Description

  The present invention relates to a drunk driving prevention system that prevents drunk driving of a vehicle.

In recent years, the number of vehicle accidents caused by drunk driving has increased, and the momentum for preventing drunk driving has further increased. As one countermeasure, the driver's morals may be further improved, but it is also desired that the vehicle manufacturer take measures. As an example of measures to be taken on the vehicle side, when a device capable of measuring alcohol content is installed in the vehicle from the exhaled breath that the person to be detected actually exhales, It is most effective from the aspect of drunk driving prevention to install a drunk driving prevention system prohibiting engine start in the vehicle. Various kinds of drunk driving prevention systems have been conceived so far, and technical examples thereof are disclosed in Patent Documents 1 and 2, for example.

  By the way, when the drunk driving prevention system is in a vehicle operation restricted state such as engine start prohibition etc., it is also possible to call a non-drinker instead and let the non-drinker drive on behalf of the vehicle. Since it is necessary to cancel the drunk driving prevention system that has become the original state, it is necessary to incorporate this type of releasing function into the drunk driving prevention system. For example, if the vehicle operation restriction state of the drunk driving prevention system is canceled on the vehicle side, it is necessary to provide the vehicle with several parts groups (including functions) of this cancellation function. Therefore, when the cancellation function of the drunk driving prevention system is provided in the vehicle, there is a possibility that a problem that a large design change has to be made on the vehicle that has been used until now can be denied, and some solution has been desired. .

  An object of the present invention is to provide a drunk driving prevention system that does not involve a significant change in the vehicle when incorporating the release function when a vehicle operation is restricted when the driver is a drunk person.

  In order to solve the above problems, the present invention has a drinking presence / absence judging means for judging whether or not the driver of the vehicle has drunk, and when the drinking presence / absence judging means judges that there is drinking, the operating state of the system In the drunk driving prevention system that switches the vehicle operation to the vehicle operation restricted state that restricts the use of the vehicle operation and restricts the use of the vehicle operation that can be operated, the vehicle operation restricted state is released to the portable terminal that can be held by the vehicle occupant The gist is that the vehicle operation restriction state is released on the portable terminal side by providing the releasing means.

  According to this configuration, when the drinking / no drinking determination unit determines that the driver is a drinker, the operation state of the drunk driving prevention system is switched to a vehicle operation restricted state in which free vehicle operation is not permitted, and the vehicle operation is changed. Will be subject to usage restrictions. For this reason, when the driver has drunk, the engine cannot be started freely, so that drunk driving of the vehicle can be prevented. Moreover, in order to cancel the vehicle operation restricted state of the drunk driving prevention system, the vehicle operation restricted state is canceled by using a release means provided in the portable terminal. Therefore, in this configuration, since the mobile terminal is provided with a canceling unit used when canceling the vehicle operation restricted state of the drunk driving prevention system, it is not necessary to mount this type of functional component on the vehicle. Therefore, since it is not necessary to add various parts to the vehicle, no significant changes are made to the vehicle used so far.

The gist of the present invention is that the portable terminal has a key function.
According to this configuration, since the mobile terminal is provided with a key function, various operations of the vehicle (for example, door lock locking / unlocking) can be performed if the mobile terminal is carried.

  In the present invention, the release means determines whether or not the operation means provided in the portable terminal has been operated in an order that allows the release of the vehicle operation restricted state, and the operation means operates in the order. The gist of the invention is to release the vehicle operation restricted state on the condition.

  According to this configuration, if the vehicle operation restriction state of the drunk driving prevention system is released by operating the operation means of the mobile terminal according to a predetermined procedure, the driver who performs the release operation is a drinker. If so, it is often the case that the operation means of the portable terminal cannot be performed accurately due to sickness. Therefore, if the operating means of the mobile terminal can accurately operate the release condition of the vehicle operation restriction state, whether or not the driver who performs the release of the vehicle operation restriction state of the drunk driving prevention system is a drunk person It becomes possible to more accurately determine whether or not to drink.

  In the present invention, the vehicle key system uses an electronic key that wirelessly transmits a key code unique to the key, and the key code transmitted wirelessly from the electronic key and the key code registered in the vehicle, Is an electronic key type that allows the vehicle operation on condition that the key verification is established, and the release means is operated in the order, The gist is to cancel the vehicle operation restriction state on condition that the key collation performed between the portable terminal and the vehicle is established when the vehicle is operated by an electronic key.

  According to this configuration, cancellation of the vehicle operation restriction state is also conditional on the establishment of key verification performed wirelessly between the electronic key and the vehicle, so that the driver holding the electronic key is close to the vehicle. If you do not speak, the vehicle operation restriction state of the drunk driving prevention system will not be released. Therefore, for example, it becomes difficult for an unauthorized person to establish a cancellation condition to set the drunk driving prevention system in a released state, and it is possible to ensure the accuracy of the cancellation operation of the drunk driving prevention system.

  In the present invention, the mobile terminal obtains a release permission notice as a proof necessary for performing the release from the communication terminal that functions as a component when performing the release operation of the vehicle operation restricted state. It is determined whether or not the vehicle operation restricted state is released on condition that the release permission notice is obtained.

  According to this configuration, when determining whether or not the vehicle operation restricted state can be released, whether or not the vehicle operation restricted state can be released is determined by checking whether the mobile terminal has acquired the release permission notification output from the communication terminal. Therefore, it is possible to determine whether or not the vehicle operation restricted state can be canceled by a simple determination process of checking whether or not the release permission notification is received.

  In the present invention, the release means counts the elapsed time since the system enters the vehicle operation restricted state with the portable terminal, and the vehicle operation restriction is performed on the condition that the measured time exceeds a set value. The gist is to cancel the state.

  According to this configuration, when a certain time elapses after the system enters the vehicle operation restricted state, the vehicle operation restricted state of the system is automatically released, so that no special operation is required when releasing the vehicle operation restricted state. It becomes.

  In the present invention, the key system of the vehicle uses an electronic key that wirelessly transmits a key code unique to the key, and the key code transmitted wirelessly from the electronic key and the key code registered in the vehicle A collation communication system that is used when performing the key collation in the key system, and the vehicle The gist is that the same communication system is used as the cancel communication system used when canceling the operation restricted state by wireless communication.

According to this configuration, since it is not necessary to prepare communication parts individually, it is possible to reduce the number of parts required for the communication system.
In the present invention, the vehicle key system uses an electronic key as the portable terminal that wirelessly transmits a key code unique to a key, and registers the key code transmitted wirelessly from the electronic key and the vehicle The electronic key type that performs key collation by comparing with the key code that has been made and permits the vehicle operation on condition that the key collation is established, and the release means restricts the use of the electronic key by When the system is in a vehicle operation restricted state, when the release condition of the vehicle operation restricted state is established on the electronic key side, the electronic key subjected to the use restriction is returned to the original normal state, thereby The gist is to cancel the vehicle operation restriction state.

  According to this configuration, even if the drunk driving prevention system takes an operation state in which the use restriction is applied to the electronic key and the vehicle operation restriction state is taken, the operation to return the electronic key in the use restriction state to the original normal state It is possible to cancel the vehicle operation restriction state of the drunk driving prevention system by taking

  In the present invention, when the release means sets the system to a vehicle operation restricted state by restricting the use of the vehicle, a release permission notice is issued when a release condition for the vehicle operation restricted state is established on the mobile terminal side. Is registered in the mobile terminal, the cancellation permission notification is output from the mobile terminal to the vehicle, and the vehicle operation restricted state is released by returning the vehicle that has been restricted to the original normal state. The gist is to do.

  According to this configuration, even if the drunk driving prevention system is in an operation state where the vehicle operation restriction state is caused by the use restriction being applied to the vehicle, when the release condition is established on the mobile terminal side, the release permission notification is issued. It is possible to cancel the vehicle operation restriction state of the drunk driving prevention system by outputting to the vehicle from the portable terminal and causing the vehicle in the use restriction state to return to the original normal state.

  ADVANTAGE OF THE INVENTION According to this invention, when a driver | operator is a drunk person and a vehicle operation | movement is restrict | limited, when incorporating this cancellation | release function, the drunk driving prevention system which does not accompany a vehicle drastic change can be provided.

(First embodiment)
Hereinafter, a first embodiment of a vehicle operation restriction system for drinking a vehicle embodying the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the vehicle 1 is equipped with a hands-free system 2 that can perform door locking / unlocking and engine starting without actually operating a vehicle key. The hands-free system 2 uses an electronic key that transmits a key-specific ID code Cid by wireless communication. In this example, this type of electronic key is a mobile phone with a key function in which a mobile phone is equipped with an electronic key function. Phone 3 is in use. The hands-free system 2 transmits a request signal Srq from the vehicle 1, and when the mobile phone 3 with a key function receives this request signal Srq, the mobile phone 3 with a key function responds to the ID with the ID code Cid on it. When the signal Sid is returned to the vehicle 1 by narrow-range transmission, and the ID code Cid of the mobile phone 3 with the key function matches the ID code Cid of the vehicle 1, door locking / unlocking and engine starting are permitted or executed. . The hands-free system 2 constitutes a drunk driving prevention system and a key system. The mobile phone 3 with a key function constitutes a mobile terminal and an electronic key, and the ID code Cid corresponds to the key code.

  The hands-free system 2 will be described below. The vehicle 1 is provided with a verification ECU 4 that performs ID verification with the mobile phone 3 with a key function used as a vehicle key. The verification ECU 4 includes an out-of-vehicle LF transmitter 5 that is embedded in a door or the like and capable of transmitting an LF band signal outside the vehicle, and an in-vehicle LF transmitter 6 that is embedded under the floor of the vehicle and that can transmit an LF band signal into the vehicle. And an RF receiver 7 that is embedded in an in-vehicle rearview mirror and can receive an RF band signal. These LF transmitters 5 and 6 can transmit the request signal Srq to the surroundings, and the outside LF transmitter 5 forms an outside communication area E1 (see FIG. 2) of the request signal Srq around the vehicle, and the in-vehicle LF transmission. The machine 6 forms an in-car communication area E2 (see FIG. 2) for the request signal Srq throughout the car. In addition, collation ECU4 comprises a drinking / no drinking determination means.

  As shown in FIG. 1, for example, a touch sensor 9 embedded in an outside door handle knob 8 (see FIG. 2) is connected to the verification ECU 4. The touch sensor 9 detects an operation of touching the outside door handle knob 8 when the operator releases the locked door lock. For example, a lock button 10 provided on the outside door handle knob 8 is connected to the verification ECU 4. The lock button 10 is pushed when the operator locks the unlocked door lock. A door ECU 11 that controls the locking and unlocking of the door lock is connected to the verification ECU 4 through an in-vehicle LAN (Local Area Network) 12. The door ECU 11 drives the door lock motor 13 based on a command from the verification ECU 4 to place the door lock in a locked state or an unlocked state.

  On the other hand, the cellular phone 3 with a key function is provided with a telephone mechanism 14 as an electrical component that operates when the cellular phone 3 performs a call or the Internet. The telephone mechanism 14 is provided with a terminal control unit 15 that performs overall control of the telephone mechanism 14 and a telephone function transmission / reception unit 16 that functions as a transmission / reception portion of various data of the telephone mechanism 14. When the operator operates the group of operation buttons of the mobile phone 3, the terminal control unit 15 performs call control under the wireless telephone communication network via the telephone function transmission / reception unit 16 and also controls the group of operation buttons of the mobile phone 3. When the operator operates the Internet, the Internet communication is performed under the wireless Internet communication network via the telephone function transmitting / receiving unit 16.

  In addition, the cellular phone 3 with a key function is provided with an electronic key mechanism 17 capable of transmitting the ID code Cid held by itself as a vehicle key to the vehicle 1 by signal data by wireless communication. The electronic key mechanism 17 transmits a communication control unit 18 that functions as a control unit for narrowband wireless communication according to the hands-free system 2, an LF reception unit 19 that can receive an LF band signal, and an RF band signal. A possible RF transmitter 20 is provided. The communication control unit 18 is provided with a memory 21 composed of, for example, an EEPROM, and the key side ID code Cid is registered in the memory 21. The communication control unit 18 reads various reception data received by the LF reception unit 19 and performs an operation of transmitting an ID signal Sid via the RF transmission unit 20. The LF receiver 19 demodulates the LF band signal received by its own LF receiving antenna 19a by the LF receiver circuit 19b, and outputs the demodulated signal to the communication controller 18 as received data. The RF transmission unit 20 can modulate the transmission data received from the communication control unit 18 using its own RF transmission circuit 20a, and can transmit the modulated transmission data from the RF transmission antenna 20b. In addition, the communication control part 18 comprises a drinking presence determination means and a cancellation | release means.

  When the vehicle 1 is in a parked state (engine stopped and door locked), the verification ECU 4 intermittently transmits a request signal Srq for the LF band from the external LF transmitter 5 to form an external communication area E1 around the vehicle. . When the mobile phone 3 with a key function enters the outside communication area E1 and receives the request signal Srq by the LF receiver 19, the mobile phone 3 with a key function responds to the request signal Srq with a confidence ID code Cid. The ID signal Sid is returned from the RF transmitter 20 as an RF band signal. When the verification ECU 4 receives the ID signal Sid via the RF receiver 7, the verification ECU 4 compares the ID code Cid registered in its own memory 22 with the ID code Cid of the mobile phone 3 with a key function (verification outside the vehicle). )I do. When the verification outside the vehicle is established, the verification ECU 4 sets the verification flag outside the vehicle in the memory 22 to recognize the establishment of the verification outside the vehicle, and activates the touch sensor 9 in standby. When the touch sensor 9 detects a touch operation on the vehicle handle knob 8 while the vehicle outside verification is established, the door ECU 11 rotates the door lock motor 13 to one side to release the locked door lock.

  On the other hand, when the vehicle 1 is in a stopped state (engine stopped and door unlocked state), the verification ECU 4 transmits a request signal Srq from the outside LF transmitter 5 when detecting that the lock button 10 is pressed. When the verification ECU 4 receives the request signal Srq and recognizes that verification outside the vehicle has been established in the ID signal Sid returned from the mobile phone 3 with a key function, the verification ECU 4 outputs a door lock locking request to the door ECU 11. Receiving the door lock locking request, the door ECU 11 rotates the door lock motor 13 to the other side to lock the unlocked door lock.

  A power supply ECU 23 that manages the power supply of the on-vehicle electrical components and an engine ECU 25 that performs ignition control and fuel injection control of the engine 24 are connected to the verification ECU 4 through the in-vehicle LAN 12. Connected to the power supply ECU 23 are an in-vehicle accessory (not shown) and an engine start switch 26 operated when the engine 24 is operated, an ACC relay 27 connected to the in-vehicle accessory, and an IG relay 28 connected to the engine ECU 25.

  After the vehicle exterior verification is established and the door lock is released, the verification ECU 4 detects that the door is opened from the courtesy switch 29, for example, and recognizes that the driver gets on the vehicle, and sends a request signal Srq from the in-vehicle LF transmitter 6. And in-vehicle communication area E2 is formed in the vehicle interior. When the ID signal Sid returned from the in-vehicle communication area E2 by the mobile phone 3 with the key function is received by the RF receiver 7, the verification ECU 4 receives the ID code Cid registered therein and the ID of the mobile phone 3 with the key function. ID verification (in-vehicle verification) is performed by comparing the code Cid. When the in-vehicle collation is established, the collation ECU 4 sets an in-vehicle collation establishment flag in the memory 22 and recognizes that the in-vehicle collation is established.

  When the boarded driver depresses the brake pedal and the engine start switch 26 is turned on (switch push start operation), the power supply ECU 23 detecting this operation confirms the in-vehicle collation result with the collation ECU 4. When the power supply ECU 23 receives notification from the verification ECU 4 that the indoor verification has been established, the power supply ECU 23 turns on the ACC relay 27 and the IG relay 28 and outputs an activation signal to the engine ECU 25. The engine ECU 25 that has received the start signal performs encrypted communication with the verification ECU 4 to confirm the in-vehicle verification result and to perform pairing to confirm that the communication destination is the verification ECU 4 that forms a pair. The engine ECU 25 that has confirmed both of these conditions starts ignition control and fuel injection control to start the engine 24.

  Further, the vehicle 1 is provided with an immobilizer system 31 that performs ID collation by wireless communication using a transponder 30 embedded in the mobile phone 3 with a key function. The immobilizer system 31 is provided with a transponder key coil 32 serving as an antenna when performing transponder communication with the mobile phone 3 with a key function. The transponder key coil 32 is mounted in a ring shape in a housing that supports the engine start switch 26 and is connected to the verification ECU 4. The immobilizer system 31 activates the transponder 30 with the driving radio wave Sv transmitted from the transponder key coil 32 by bringing the mobile phone 3 with a key function close to the transponder key coil 32, for example, and the activated transponder 30 returns a reply. This is a system that collates the code number in the transponder code signal Str on the vehicle 1 side and performs ID verification.

  When the verification ECU 4 detects that the driver has pushed the engine start switch 26 while depressing the brake pedal, the verification ECU 4 performs an operation for confirming whether or not the in-vehicle verification is established as an authentication operation before the engine start. The verification establishment target to be performed is not limited to ID verification according to the hands-free system 2. That is, the verification ECU 4 performs two verifications of ID verification according to the hands-free system 2 and ID verification according to the immobilizer system 31 when confirming the ID verification establishment in order to cope with the battery running out of the mobile phone 3 with the key function. If at least one of them is established, it is recognized that the in-vehicle verification is established. The immobilizer system 31 constitutes a key system.

  As shown in FIG. 1, the vehicle 1 is provided with a drunk vehicle operation restriction system 33 that restricts various vehicle operations such as engine starting when the driver drinks. This system 33 installs the LF transmission device 35 in, for example, a restaurant (pub, bar, etc.) 34, and the restaurant entry information Sdd for notifying that the vehicle driver has entered the restaurant 34 is sent to the LF transmission device. When the mobile phone 3 with a key function receives the restaurant entry information Sdd through LF communication, the key function of the mobile phone 3 with a key function is limited. Here, if the driver stops at a restaurant 34 such as a pub or a bar, there is a high possibility that the driver has drunk, and this is indirectly recognized as a drinking operation by entering the restaurant. The key function restriction of this example employs an engine start prohibition that prohibits starting of the engine 24 by preventing the ID signal Sid from being transmitted from the mobile phone 3 with the key function at the time of in-vehicle verification.

  The drunk vehicle operation restriction system 33 will be described below. The LF transmission device 35 includes a transmission control unit 36 that performs overall control of the LF transmission device 35, and an LF transmission unit 37 that modulates a signal in the LF band and transmits the signal. It is a transmission unit with The LF transmitter 35 is installed, for example, near the cash register of the restaurant 34 or near the door, and periodically transmits the restaurant entrance information Sdd near the exit of the restaurant 34. The restaurant entry information Sdd is, for example, an LF signal with a communication area of a few meters in diameter, and the vehicle driver has entered the restaurant 34, that is, the vehicle driver has drunk at the restaurant 34. This is a group of information for notifying information, a restaurant name, a store entry time, etc. in order to notify that there is a property. The drunk vehicle operation restriction system 33 constitutes a drunk vehicle operation restriction system.

  In addition, since the LF transmitter 35 transmits the restaurant entry information Sdd near the door of the restaurant 34, the key holder carries out the operation of opening the restaurant 34 in the process of drinking. In conjunction with this, the restaurant entry information Sdd is registered in the mobile phone 3. Furthermore, since the drinking water vehicle operation restriction system 33 transmits the restaurant entry information Sdd from the LF transmitter 35 as a signal in the LF band and causes the mobile phone 3 to receive it, the key holder The same communication system (communication system), that is, the frequency band of the LF band is used for the restricted communication system that restricts vehicle operation when drinking and the collation communication system when the mobile phone 3 performs wireless communication with the vehicle 1 during ID collation. It is performed using the same wireless communication.

  In the mobile phone 3 with the key function, the vehicle operation restriction program Dpr is written in the memory 21 of the communication control unit 18 as program data of the drinking-time vehicle operation restriction system 33 registered in the mobile phone 3 with the key function. This vehicle operation restriction program Dpr does not actually detect exhalation from the driver and detect alcohol, but reads the signal content when the LF receiver 19 receives the LF signal. In the case of the store entry information Sdd, this is a program assigned with a vehicle operation restriction function for indirectly determining drinking by restricting the key function of the mobile phone 3 with a key function. Further, the vehicle operation restriction program Dpr is also written in the memory 22 of the vehicle 1 if the operation determination of the drunk vehicle operation restriction system 33 extends to the vehicle 1 side. The communication control unit 18 sequentially executes the vehicle operation restriction program Dpr and constantly monitors whether or not the restaurant entrance information Sdd is received.

  When the communication control unit 18 receives the restaurant entry information Sdd and enters the engine start prohibited state, the communication control unit 18 sends the ID signal Sid from the RF transmission unit 20 to the vehicle 1 even if the request signal Srq is received from the vehicle 1 at the time of in-vehicle verification. The ID signal transmission lock state at the time of in-vehicle verification without reply is taken. The mobile phone 3 with a key function takes an operation of receiving a request signal Srq from the vehicle 1 for both external verification and in-vehicle verification when performing ID verification with the vehicle 1. Is included from the in-vehicle LF transmitter 5 and the in-vehicle LF transmitter 6, and by reading this, the request signal Srq can be used for both out-of-vehicle verification and in-vehicle verification. Judge whether or not. The communication control unit 18 also stops the transmission of the transponder code from the transponder 30 when the in-vehicle verification ID signal transmission lock state is entered.

  The drunk vehicle operation restriction system 33 does not restrict the transmission of the ID signal Sid from the key function mobile phone 3 when the mobile phone 3 with key function is in a normal state where the restaurant entry information Sdd is not received. Then, the engine start permission state for permitting free engine start operation of the vehicle 1 is entered. On the other hand, when the mobile phone with key function 3 receives the restaurant entry information Sdd at the restaurant 34 or the like, the mobile phone with key function 3 receives the request signal Srq from the vehicle 1 at the time of in-vehicle verification. Even if it receives, it will be in the engine start prohibition state which prohibits the engine start of the vehicle 1 when it will be in the state which cannot return ID signal Sid. That is, when the driver is a drinker, as a restriction on use, the transmission of the ID signal Sid in the in-vehicle verification is locked, and the engine start is prohibited.

  The drunk vehicle operation restriction system 33 is provided with a restriction state release function for returning the system that has entered the vehicle operation restriction state to the original normal state. This restriction state release function is written as program data in the vehicle operation restriction program Dpr registered in the memory 21. When the terminal control unit 15 recognizes that the operation button group of the mobile phone 3 has been operated to cancel the vehicle operation restriction by the operator, the terminal control unit 15 makes an inquiry to the communication control unit 18 to activate the restriction state release function (restriction state release application). . When the communication control unit 18 recognizes that the operator has performed an appropriate release operation on the mobile phone 3 in accordance with the instructions of the application, the communication control unit 18 releases the vehicle operation restriction state of the drinking-time vehicle operation restriction system 33.

Next, the operation of the drunk vehicle operation restriction system 33 configured as described above will be described.
Assuming that the user drives the vehicle 1 and goes to the restaurant 34 as shown in FIG. 3, when the vehicle 1 arrives at the parking lot 38, the engine 1 is stopped while the vehicle 1 is stopped on the parking frame of the parking lot 38. The start switch 26 is pressed to put the running engine 24 into a stopped state. Then, the driver holds the mobile phone 3 with the key function and gets off the vehicle. After getting off the vehicle 1, the driver pushes the lock button 10 on the door handle knob 8 outside the door to lock the vehicle 1 to the door. Thereby, the vehicle 1 will be in a parking state (engine stop and door lock locked state).

  Subsequently, the driver (key holder) who gets off the vehicle 1 enters the restaurant 34. When the key holder enters the restaurant 34, the driver enters the restaurant 34. When the mobile phone 3 with a key function enters the communication area Edd of the installed LF transmitter 35, the mobile phone 3 with a key function enters a state where the LF receiver 19 receives the restaurant entry information Sdd. At this time, the communication control unit 18 in the mobile phone 3 with the key function reads the restaurant entry information Sdd received by the LF receiver 19, and the received LF data at this time is the restaurant entry information Sdd. If it recognizes, even if it receives request signal Srq from vehicle 1 when performing in-vehicle collation with vehicle 1, it will be in the ID signal transmission lock state at the time of in-vehicle collation which does not perform reply operation of ID signal Sid. That is, the drunk vehicle operation restriction system 33 enters the vehicle operation restriction state, and in this example, the engine start inhibition state in which the free engine start operation is prohibited.

  Here, it is assumed that the driver who has finished eating and drinking (drinking) returns to the parking lot 38 and drives the vehicle 1 to return home. Since the parked vehicle 1 periodically transmits a request signal Srq from the outside LF transmitter 5 to form the communication area E1 outside the vehicle, when the mobile phone 3 with a key function enters the communication area E1, the key function Outside vehicle verification is performed by comparing the ID code Cid of the attached mobile phone 3 with the ID code Cid of the vehicle 1. At this time, the cellular phone 3 with a key function is in an ID signal transmission lock state. This is because the ID signal is not transmitted when the request signal Srq is in-vehicle verification. In this case, the ID signal Sid is returned to the vehicle 1 in response to the request signal Srq. If the ID code Cid transmitted from the key-equipped mobile phone 3 at this time matches the ID code Cid registered in the vehicle 1 and the vehicle outside verification is established, the unlocking of the door lock is permitted. For this reason, when this operation is detected by the touch sensor 9 when the driver grips and operates the outside door handle knob 8 of the parked vehicle 1, the door lock is unlocked.

  Subsequently, the key holder performs an operation of opening and closing the driver's seat door and getting in the vehicle. When the verification ECU 4 detects the opening / closing operation of the driver's seat door by the courtesy switch 29, the request signal Srq from the in-vehicle LF transmitter 6 is obtained. To check whether in-vehicle verification is successful. Here, when the key holder is returning from the restaurant 34, the mobile phone 3 with the key function is in the ID signal transmission lock state at the time of in-vehicle verification, so that the in-vehicle LF transmitter 6 transmits when the key holder gets on. Even if the request signal Srq is received, it does not react to this and the in-vehicle verification is not established. Therefore, even if the verification ECU 4 transmits the request signal Srq from the in-vehicle LF transmitter 6, the verification ECU 4 does not accept the ID signal Sid within a predetermined time. Therefore, even if the drunk person presses the engine start switch 26 to start the engine 24 after sitting in the driver's seat, the engine 24 cannot be started.

  Therefore, in this example, the LF transmitter 35 is installed in a place where the driver of the restaurant 34 or the like is likely to perform drinking behavior, and the restaurant is entered to notify that the driver may have drunk. Information Sdd is transmitted from the LF transmitter 35. When the key holder enters the restaurant 34 and the mobile phone 3 with the key function receives the restaurant entrance information Sdd from the LF transmitter 35, the mobile phone 3 with the key function receives the signal and the driver receives the signal. Even if it is indirectly determined that alcohol has been drunk and the request signal Srq is received by in-vehicle collation, the in-vehicle collation ID signal transmission lock state in which no response is made. Therefore, even if the key holder goes to the restaurant 34 and drinks, the mobile phone 3 with the key function at this time cannot return the ID signal Sid at the time of in-car verification, so it returns to the vehicle 1 after eating and drinking. Even if the engine 24 is started, the engine 24 cannot be started by the cellular phone 3 with the key function. Thus, since the engine start of the vehicle 1 is limited when the key holder has a possibility of drinking, drunk driving can be prevented.

  Further, in the alcohol drinking vehicle operation restriction system 33 of this example, the LF transmitter 35 is installed in the restaurant 34, and the mobile phone 3 with a key function receives the restaurant entry information Sdd transmitted from the LF transmitter 35. Whether or not alcohol is consumed is determined by an indirect method of checking whether or not the alcohol has been consumed. For this reason, when detecting whether or not the driver is drinking, it is not necessary to mount a large-scale alcohol detection device on the vehicle 1 to detect the amount of alcohol in the intake amount by actually blowing in, for example. This example is a system that requires only software setting processing (application registration) for the cellular phone 3 with a key function and the vehicle 1. Therefore, for example, it is not necessary to mount a large-scale alcohol detection device on a vehicle of a person who does not drink alcohol, and the effect is high even when considering the cost of vehicle parts and the interior of the vehicle.

  For example, it is also possible for the store side to lock the ID signal transmission of the mobile phone 3 with the key function only to the drinker and selectively prohibit the engine start. As a specific example in this case, as shown in FIG. 4, a transmission operation device 39 that transmits restaurant entry information Sdd from the LF transmission device 35 when a button operation is performed is provided near the cash register 40, etc. The restaurant entry information Sdd is selectively transmitted from the LF transmitter 35 only when the employee of the restaurant 34 operates the transmission button 39a of the transmission operation device 39.

  In this case, when the employee at the store side determines the owner of the mobile phone 3 with the key function, that is, the driver is a drinker, By operating the transmission operation device 39, the restaurant entry information Sdd is transmitted from the LF transmission device 35, and the mobile phone 3 with a key function is put into the ID signal transmission lock state during in-vehicle verification. On the other hand, when it is determined that the owner of the mobile phone 3 with the key function, that is, the driver is a non-drinker, the restaurant entry information Sdd is transmitted from the LF transmission device 35 without operating the transmission operation device 39. I won't let you. As a result, the cellular phone 3 with a key function is not restricted, and the engine can be started with the cellular phone 3. Therefore, it is difficult for the non-drinker to lock the mobile phone 3 with the key function, and convenience is improved.

  The condition when the mobile phone 3 with a key function is in the in-vehicle ID signal transmission lock state is limited to receiving the restaurant entry information Sdd transmitted by the LF transmitter 35 installed in the restaurant 34. Not. For example, as shown in FIG. 5, if the mobile phone 3 with a key function is equipped with a payment function 41 (payment IC, payment application) for paying with electronic money, the possibility of drinking such as a tavern or a bar is possible. It may be a condition that payment is made at a certain place. In this case, each restaurant 34 is provided with a payment terminal 42 capable of performing payment with electronic money with the mobile phone 3 with key function, and the mobile phone 3 with key function has a payment function. As a function 41, it is necessary to attach an IC chip for electronic money settlement. The communication method of the settlement function 41 is a high-speed non-contact communication method that has high security and is difficult to intercept data.

  At this time, the payment is made by holding the mobile phone 3 with the key function over the payment terminal 42 installed near the cash register of the restaurant 34, but the terminal control unit 15 pays with the payment terminal 42. When the settlement information Smn is obtained from the payment terminal 42, the store name, the store system, the order menu, etc. obtained from the settlement information Smn are viewed, and it is confirmed whether or not the store where the restaurant was eaten at this time is a pub or a bar. Do. And if the terminal control part 15 judges that the restaurant 34 at this time is a shop where drinking is possible, it will output the restriction | limiting operation request | requirement Skc to the communication control part 18 as a notification to that effect. When the communication control unit 18 receives the restricted operation request Skc from the terminal control unit 15, the communication control unit 18 enters the in-vehicle verification ID signal transmission lock state by receiving the request.

  By the way, this kind of payment terminal 42 has been installed more and more for convenience of payment, as represented by convenience stores and the like. Therefore, in order to lock the ID signal transmission of the mobile phone 3 with the key function using the LF transmitter 35 first mentioned, it is necessary to newly install the LF transmitter 35 in each restaurant 34. If the payment terminal 42 is installed in the restaurant 34 in advance by using the system structure that locks to the ID signal transmission of the mobile phone 3 with the key function using the payment information Smn, a new device is connected to the restaurant 34. There is no need to install. Therefore, when locking the ID signal transmission to the mobile phone 3 with the key function using the payment information Smn, it leads to an advantage that the parts cost of the drunk vehicle operation restriction system 33 can be kept low.

  Furthermore, even when the mobile phone 3 with a key function is restricted using the payment information Smn, the store side can selectively lock the mobile phone 3 with a key function only for a drinker. In this case, as shown in FIG. 5, the payment terminal 42 is provided with a determination operation device 43 that can add a non-drinker notification Snd indicating that the payer is not a drinker to the payment information Smn. When the employee determines that the key holder is a non-drinker at the time of payment, the employee operates the determination button 43a of the determination operation device 43 to send the settlement information Sm n to the mobile phone 3. Non-drinker notification Snd is added to this composite information Stt (settlement information Smn and non-drinker notification Snd) in the mobile phone 3 so that the mobile phone 3 with a key function does not enter the in-vehicle verification ID signal transmission lock state. To.

  Further, the engine start restriction of the drunk vehicle operation restriction system 33 is not limited to the method of locking the ID signal transmission of the mobile phone 3 with a key function. For example, as shown in FIG. 6, when the mobile phone 3 with a key function receives a request signal Srq from the in-vehicle LF transmitter 6, the ID signal Sid returned to the vehicle 1 includes an engine other than the ID code Cid. A method of including an engine start restriction request Seg for prohibiting the start and returning it to the vehicle 1 may also be used. When the verification ECU 4 receives the ID signal Sid via the RF receiver 7 and confirms that the engine start restriction request Seg is included in the ID signal Sid, the ID code of the mobile phone 3 with the key function is temporarily set to the vehicle 1. Even if it coincides with that, the in-vehicle collation at this time is regarded as not established, and the engine is not permitted to start. In this case, it is necessary to add a reading function for decoding the engine start restriction request Seg included in the ID signal Sid to the data reading function of the verification ECU 4.

  Further, as shown in FIG. 7, the engine start restriction of the drunk vehicle operation restriction system 33 is as follows. When the mobile phone 3 with a key function receives the request signal Srq and returns the ID signal Sid, the ID code Cid that is returned at this time is returned. May be transmitted with a fake code. In this case, when the verification ECU 4 transmits the request signal Srq from the in-vehicle LF transmitter 6, the ID signal Sid transmitted from the mobile phone 3 with a key function is received by the RF receiver 7, but the ID signal Sid at this time Since the ID code Cid included in does not match that of the vehicle 1, the engine start is not permitted.

  Further, the engine start restriction of the drunk vehicle operation restriction system 33 may be a system in which the power supply of the mobile phone 3 with a key function is shut down for a predetermined time as shown in FIG. In this case, even if the driver pushes the engine start switch 26 to start the engine 24 and the verification ECU 4 transmits the request signal Srq from the in-vehicle LF transmitter 6, the key function at this time Since the attached mobile phone 3 is not in the activated state, the mobile phone 3 with the key function does not take a state of returning the ID signal Sid in response to the request signal Srq. Therefore, in-vehicle collation communication is not established between the mobile phone 3 with a key function and the vehicle 1, and the drunk vehicle operation restriction system 33 enters a state in which engine start is not permitted.

  Here, even if the driver stops at the restaurant 34, there is a case where he / she does not drink there. Therefore, in order to get on the vehicle 1 and return home, it is necessary to cancel the vehicle operation restriction state of the drunk vehicle operation restriction system 33 at this time There is. In this case, first, the operation button group of the mobile phone 3 with a key function is operated, and the terminal control unit 15 starts up the restricted state release function registered in the mobile phone 3 with the key function, that is, the restricted state release application. When the restriction state release application starts, the mobile phone 3 with a key function enters the operation restriction release operation input state, and the engine 45 is prohibited from being displayed on the screen 45 of the mobile phone 3 with the key function as shown in FIGS. Release operation input screens 46 to 48 used for inputting the state release operation are displayed. The release operation input screens 46 to 48 are input screens that prompt the key holder to input a button operation of a predetermined order or predetermined condition within a predetermined time period in order to verify whether the key holder is not drunk.

  As this canceling method, for example, as shown in FIG. 9, there is a numerical value input formula in which numerical values are sequentially displayed on the canceling operation input screen 46 at short time intervals and the key holder is made to follow the input of the displayed numerical values. When the release method is a numerical value input method, the input screen 46 includes a numerical value display field 46a for displaying a numerical value to be input, and a numerical value actually inputted by the key holder by operating the operation button 44 (alphanumeric key). There is a numerical value input field 46b to be displayed. In the release operation input screen 46, the numerical value displayed in the numerical value display field 46a is switched at a short time interval (a few seconds of commas), and the key holder of the mobile phone 3 with the key function so as to follow the numerical value in the numerical value display field 46a. The operation button 44 is operated to input the numerical value following the numerical value input field 46b. The operation button 44 constitutes an operation unit.

  Here, if the driver is in a normal state not drunk, it should be possible to perform this input operation without any problem. When the terminal control unit 15 confirms that all the numerical values have been input correctly, the terminal control unit 15 recognizes that the key holder is a non-drinker, and sends a lock state release request Skr (see FIG. 1) to the communication control unit 18. Output. Upon receiving the lock state release request Skr, the communication control unit 18 releases the in-vehicle verification ID signal transmission lock state that has been in the set state until then, and returns to the normal state in which the ID signal Sid can be transmitted freely. That is, the drunk vehicle operation restriction system 33 is in an engine start permission state, and a free engine start operation is possible.

  Therefore, after releasing the ID signal transmission lock state during in-vehicle verification of the mobile phone 3 with a key function, the engine start switch 26 is pushed while the brake pedal is depressed by the driver while the shift lever is in the parking position. When operated, the in-vehicle collation is executed again even when the engine start switch 26 is operated. If the mobile phone 3 with the key function at this time returns to the normal state, the request received from the in-vehicle LF transmitter 6 An ID signal Sid is returned to the vehicle 1 in response to the signal Srq. The verification ECU 4 recognizes that the in-vehicle verification has been established if the ID code Cid of the ID signal Sid received from the mobile phone 3 with a key function matches the vehicle 1 after transmitting the request signal Srq from the in-vehicle LF transmitter 6. To allow the engine to start.

  Therefore, in this example, since the cancel function for canceling the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is provided, the vehicle 1 is returned to the original normal state if a correct release operation is performed with the mobile phone 3 with the key function. It becomes possible to return to. Moreover, since the cancellation | release of the vehicle operation | movement restriction | limiting state of this example is performed by the mobile telephone 3 with a key function, it is not necessary to mount this kind of cancellation | release function in the vehicle 1 variously. Therefore, since it is not necessary to add various parts of the vehicle operation restriction state cancellation system to the vehicle 1, no significant changes are made to the vehicle 1 used so far.

  As another release method, for example, as shown in FIG. 10, there is a memorization method in which a numerical value (including English letters) notified to the key holder in advance is input. When the release method is the memorization method, the release operation input screen 47 has a numerical value input field 47a in which a numerical value actually input by the key holder operating the operation button 44 of the mobile phone 3 with a key function is displayed. . When the terminal control unit 15 confirms that the numerical value input in the numerical value input field 47a matches the numerical value group notified in advance, the key holder recognizes that the key holder is a non-drinker, and the drunk vehicle operation restriction system A lock state release request Skr is output to the communication control unit 18 so as to put 33 in the release state.

  Furthermore, as another cancellation method, for example, as shown in FIG. 11, there is a puzzle type in which a puzzle (including a game or the like) is solved within a predetermined time. When the release method is a puzzle method, a plurality of puzzle parts 48 a are displayed on the release operation input screen 48. The key holder moves the puzzle part 48a by operating the operation button 44 of the mobile phone 3 with a key function, and solves the puzzle in a suitable position and orientation. When the terminal control unit 15 confirms that the key holder has solved the puzzle within a predetermined time on the release operation input screen 48, the terminal control unit 15 recognizes that the key holder is a non-drinker, and sets the drunk vehicle operation restriction system 33. A lock state release request Skr is output to the communication control unit 18 so as to enter the release state.

  Canceling the engine start prohibition state involves a button group operation of the mobile phone 3 with a key function, that is, a button operation input type such as a numerical input type, a memorization type, a puzzle type, etc. As a condition. By the way, the in-vehicle LF transmitter 6 moves to an operation of periodically transmitting a request signal Srq after opening / closing the door when the driver gets in the vehicle, and the out-of-vehicle LF transmitter 5 is periodically operated during parking. The operation of transmitting the request signal Srq is performed. Therefore, when the release input operation is normally performed on the mobile phone 3 with the key function, the mobile phone 3 with the key function is located in the communication area E2 (E1) for in-vehicle verification (external verification) at this time, and the in-vehicle LF transmission is performed. If the request signal Srq transmitted from the machine 6 (the LF transmitter 5 outside the vehicle) can be received, the engine start prohibition state is canceled in addition to the cancellation condition at this time.

  In this case, for example, in a restaurant 34 where the request signal Srq does not reach, a normal person who has a normal sense of not drinking (non-drinker) performs a release operation with the mobile phone 3 with a key function, and inputs a numerical value and memorizes it. Even if various events such as puzzles are cleared, if the clear operation is performed in the restaurant 34, the mobile phone 3 with the key function is not in a situation of receiving the request signal Srq from the vehicle 1, At this time, the engine start prohibition state is not released. For this reason, a situation in which the engine start prohibition state is illegally canceled by a normal person who is not drunk is less likely to occur, and the effect of preventing drunk driving is further enhanced.

  Further, the release of the in-vehicle verification ID signal transmission lock state of the mobile phone 3 with a key function may be performed using a release device 49 dedicated to canceling the transmission lock installed in the restaurant 34 as shown in FIG. . When the signal transmission start button 49a of the cancel device 49 is pressed, the cancel device 49 generates a lock state cancel request signal Sot for the LF band for requesting cancel of the in-vehicle verification ID signal transmit lock state of the mobile phone 3 with a key function. Narrow band transmission is performed by signals in the LF band during the time. When the mobile phone 3 with a key function receives the lock state release request signal Sot transmitted from the release device 49 by the LF receiver 19, the mobile phone 3 with the key function releases the in-vehicle verification ID signal transmission lock state, and the engine of the drunk vehicle operation restriction system 33. Release the start prohibition state. The release device 49 constitutes a communication terminal, and the lock state release request signal Sot constitutes a release permission notice.

  The cancellation of the engine start prohibition state of the drunk vehicle operation restriction system 33 may be an exhalation measurement type using an alcohol detector 50 installed in a parking lot 38 or the like, as shown in FIG. In this case, an alcohol detector 50 that actually inhales and measures the amount of alcohol in the exhalation is installed at each outdoor location such as the parking lot 38. The alcohol detector 50 includes a detection unit 51 that works as a location where a person to be detected (key holder) actually blows exhalation, and an alcohol measurement unit 52 that actually measures the amount of alcohol in the exhalation taken from the detection target person. An LF transmitter 53 is provided that can transmit data of the amount of alcohol calculated by the alcohol measuring unit 52 as a measurement information using a signal in a narrow LF band. The alcohol detector 50 also constitutes a communication terminal.

  When canceling the engine start prohibition state of the drunk vehicle operation restriction system 33, the key holder performs an operation of blowing the breath to the detection unit 51 after starting the measurement of the alcohol detector 50. The alcohol measuring unit 52 calculates the amount of alcohol from the exhaled breath obtained at that time, and if no alcohol is contained in the exhaled breath, transmits the lock state release request signal Sot from the LF transmitting unit 53 within a predetermined range. When the mobile phone with key function 3 receives the lock state release request signal Sot transmitted from the alcohol detector 50 by the LF receiver 19, if the own operation state is the in-vehicle verification ID signal transmission lock state, this lock state To return to the original normal state. Thereby, the engine start prohibition state of the drunk vehicle operation restriction system 33 is released, and the engine start operation can be freely performed by the mobile phone 3 with the key function.

  Further, the drunk vehicle operation restriction system 33 is limited to the prohibition state continuation type in which the engine start prohibition state is continued until the release operation is performed on the mobile phone 3 with a key function when the system is in the engine start prohibition state. Not. For example, as shown in FIG. 14, the drunk vehicle operation restriction system 33 measures the elapsed time since the system is in the engine start prohibited state, and when this elapsed time exceeds a set value, the engine start prohibited state. A time-up type in which is automatically canceled may be used. When the drunk vehicle operation restriction system 33 is of the time-up type, the communication control unit 18 measures the elapsed time after the ID signal transmission lock state at the time of vehicle verification by a counter, a timer, etc., and the elapsed time at this time When the value becomes equal to or greater than the predetermined value, the in-vehicle verification ID signal transmission lock state is canceled, and the engine start state of the drunk vehicle operation restriction system 33 is canceled.

  In addition, when the drinking-time vehicle operation restriction system 33 is a time-up type, the remaining time until the time when the engine start prohibition time is up is displayed on the display 54 installed in the center cluster in the vehicle. It may be added to the hour vehicle operation restriction system 33. In this case, when the engine depresses the engine start switch 26 while the driver depresses the brake pedal while the shift lever is at the parking position, the verification ECU 4 transmits the request signal Srq from the in-vehicle LF transmitter 6. When the mobile phone 3 with the key function at this time receives the request signal Srq transmitted from the in-vehicle LF transmitter 6, the ID code Cid is not returned, but the engine start prohibited state is set. Remaining time information Stm related to the remaining time until the time is up is transmitted from the RF transmission unit 20 to the vehicle 1 by an RF band signal.

  When the verification ECU 4 receives the remaining time information Stm at the RF receiver 7 when the request signal Srq is transmitted from the in-vehicle LF transmitter 6, the verification ECU 4 decodes the remaining time information Stm until the engine start prohibition state is released. The remaining time is confirmed, and the remaining time data is output to the screen control ECU 55 (see FIG. 1) through the in-vehicle LAN 12. When the remaining time data is input from the verification ECU 4, the screen control ECU 55 displays this data on the display 54, and displays the remaining time until the engine start prohibition state of the drunk vehicle operation restriction system 33 times out on the display 54. Display numerical values. As a result, it is possible to notify the driver of the time until the engine start prohibited state is released, and it is possible to eliminate the inconvenience that it is not known when the engine start prohibited state is released It becomes.

  Moreover, the release of the ID signal transmission lock state during in-vehicle verification of the mobile phone 3 with a key function may be performed not on the mobile phone 3 side with a key function but on the vehicle 1 side. As an example, for example, as shown in FIG. 15, it may be a condition whether or not the vehicle exterior door handle knob 8 or the lock button 10 of the vehicle 1 is operated according to a predetermined procedure. For example, when the lock button 10 is pressed for a long time, the drunk vehicle operation restriction system 33 enters the operation restriction release operation input state, and in this state, the pull-in operation of the door handle knob 8 and the push operation of the lock button 10 are performed. When it is confirmed that the steps are performed in a predetermined order, the verification ECU 4 recognizes that the engine start prohibition state of the drunk vehicle operation restriction system 33 may be canceled. The collation ECU 4 that has recognized the release permission receives from the LF transmitters 5 and 6 a restriction state release request signal Szz including a lock state release request signal Sot for notifying that fact and an ID code Cid registered in advance in the vehicle 1. It transmits with the signal of LF band.

  When the cellular phone 3 with a key function receives the restricted state release request signal Szz by the LF receiver 19, the mobile phone 3 with the key function decodes the data in the restricted state release request signal Szz. At this time, when the mobile phone 3 with a key function recognizes that the lock state release request signal Sot is included in the received LF signal, the vehicle 1 makes a request to release the vehicle operation restriction state of the drunk vehicle operation restriction system 33. The ID code Cid in the subsequent signal Szz is compared with the ID code Cid registered in itself. Then, if the collation of the ID code Cid is established, the mobile phone 3 with the key function determines that the correct restricted state release request signal Szz has been received, and releases its own in-vehicle collation ID signal transmission lock state.

  When the in-vehicle verification ID signal transmission lock state of the mobile phone 3 with a key function is released on the vehicle 1 side, the operation required on the vehicle 1 side at this time is the operation of the outside door handle knob 8 or the lock button 10. It is not limited to being. In other words, in addition to these operation parts, the vehicle 1 is provided with various operation switches (operation buttons) used when operating on-vehicle equipment, accessories, and the like. Needless to say, it can be used. When this release method is adopted, a release-dedicated switch may be prepared near the driver's seat in the vehicle, for example.

  In addition, when the ID signal transmission lock state at the time of in-vehicle verification of the mobile phone 3 with a key function is released on the vehicle 1 side, a method for prompting the key holder used by the mobile phone 3 with the key function to input a predetermined button is applied. May be. That is, when one operation button in the vehicle is pushed, operation input screens 46 to 48 as shown in FIGS. 9 to 11 are displayed on the display 54 in the vehicle, and the conditions given on the operation input screens 46 to 48 are set in the vehicle. Operate the various operation buttons to clear. When the verification ECU 4 confirms that the operation input screens 46 to 48 have been cleared, the verification ECU 4 transmits a restriction state release request signal Szz to that effect from the LF transmitters 5 and 6 using a signal in the LF band, and is equipped with a key function. The ID signal transmission lock state at the time of in-car verification of the telephone 3 is released.

  Furthermore, the method of registering the lock state release request signal Sot in the mobile phone 3 with the key function is not limited to registering it directly in the mobile phone 3 with the key function. For example, as shown in FIG. Assuming that this type of registration operation is started before going outside, the vehicle 1 may be used. As an example of this case, a release notification signal Sob including the lock state release request signal Sot and the ID code Cid registered in the vehicle 1 is sent to the parking lot 38 outside the restaurant 34 as an RF band signal. Attach an out-of-store release device 56 that can be used to send calls. Then, the restaurant 34 side acquires the ID code Cid of the visitor's vehicle 1 in advance, and when the employee determines that the driver is not a drinker at the time of payment on the way home, the non-drinker's vehicle 1 The cancellation notification signal Sob including the ID code Cid is transmitted from the store cancellation device 56 to the parking lot 38.

  When the vehicle 1 receives the release notification signal Sob by the RF receiver 7, the vehicle 1 decodes the data in the release notification signal Sob. At this time, when the vehicle 1 recognizes that the received RF signal includes the lock state release request signal Sot, the vehicle 1 recognizes that a request for releasing the drunk vehicle operation restriction system 33 is received from the restaurant 34, and continues. The ID code Cid in the signal Sob is compared with the ID code Cid registered in itself. When the verification of the ID code Cid is established, the vehicle 1 enters a lock state release permission state, and transmits a restriction state release request signal Szz from the LF transmitters 5 and 6 as an LF band signal. That is, one specific vehicle among a plurality of vehicles existing in the parking lot 38 is in a lock state release permission state in which the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is permitted to be released. Call to release the restricted state.

  When the key holder goes out of the store and the mobile phone 3 with the key function receives the restriction state release request signal Szz from the vehicle 1 by the LF receiver 19, the mobile phone 3 with the key function enters the restriction state release request signal Szz. Decipher the data. When the mobile phone 3 with the key function recognizes that the reception LF signal includes the lock state release request signal Sot, a request for releasing the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is received from the vehicle 1. And ID verification of the ID code Cid in the subsequent signal Szz is performed. And if this ID collation is materialized, the mobile telephone 3 with a key function will recognize that the vehicle 1 is in a lock release permission state, and will release the ID signal transmission lock state at the time of in-vehicle collation. In this specific example, it is needless to say that the determination of the presence or absence of drinking is not limited to the employee's confirmation, and an actual measurement using an alcohol detector is also possible.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) The drunk vehicle operation restriction system 33 for preventing drunk driving is provided with a release function for releasing the vehicle operation restriction state of the drunk vehicle operation restriction system 33. The hour vehicle operation restriction system 33 can be returned to the original normal state. Further, when this release function is provided on the mobile phone 3 with key function side, it is not necessary to provide various functional parts for the release system on the vehicle 1 side. Therefore, if the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is canceled on the key side, it is not necessary to add various parts to the vehicle 1, so that the vehicle 1 that has been used up to now can be used. No significant changes are made.

  (2) Since the vehicle operation restriction state of the drinking alcohol vehicle operation restriction system 33 is canceled using the mobile phone 3 with a key function having a key function, the portable terminal used when releasing the vehicle operation restriction state Thus, various operations (door lock locking / unlocking operation, engine starting operation, etc.) of the vehicle 1 can be performed.

  (3) When the cancellation function of the drinking alcohol vehicle operation restriction system 33 is a numerical input type, memorization type, or puzzle type button operation input type, since the drinker is weak in judgment due to alcohol, these cancellation functions are normal. There are many situations that cannot be cleared. Therefore, if the cancellation function of the drinking-time vehicle operation restriction system 33 is set to a numerical input type, memorization type, or puzzle type button operation input type, the vehicle movement restriction state of the drinking-time vehicle movement restriction system 33 is released. In doing so, it is possible to more accurately determine whether or not the driver is a drinker.

  (4) The vehicle operation restriction state of the drinking alcohol movement restriction system 33 is the normal button input (numerical input type, memorization type, puzzle type screen clear) on the mobile phone 3 with a key function, and ID verification. If two conditions are satisfied (external vehicle verification or in-vehicle verification), for example, even if normal button input can be performed with the cellular phone 3 with a key function, ID verification is not established at that time. The vehicle operation restriction state of the drunk vehicle operation restriction system 33 is not released. For this reason, for example, it becomes impossible to cancel the vehicle operation restriction state of the drunk vehicle operation restriction system 33 by fraud such as having a non-drinker clear the screens 46 to 48 in advance away from the vehicle 1. It is possible to ensure the accuracy of the unlocking operation of the vehicle operation restriction system 33 during drinking.

  (5) The vehicle operation restriction state of the drinking alcohol vehicle operation restriction system 33 can be released by registering the lock state release request signal Sot issued from the release device 49 in the mobile phone 3 with a key function. . Therefore, in this case, whether or not the unlocked vehicle operation restriction system 33 releases the vehicle operation restriction state is determined by checking whether or not the lock state release request signal Sot is registered in the mobile phone 3 with the key function. It can be implemented with a simple determination process.

  (6) When the drinking-time vehicle operation restriction system 33 is a time-up type, the vehicle 1 automatically returns to the original normal state after a certain period of time has elapsed since the vehicle operation was restricted. For this reason, when returning the drunk vehicle operation restriction system 33 from the vehicle operation restriction state to the original normal state, a special release operation is not required, which is highly effective from this viewpoint.

  (7) When canceling the vehicle operation restriction state by registering the LF band lock state release request signal Sot issued from the release device 49 (outside store release device 56) in the mobile phone 3 with a key function, this example In the hands-free system 2, the verification communication system used when performing ID verification wirelessly between the vehicle 1 and the mobile phone 3 with the key function, and the restaurant of the LF transmitter 35 to make the system operation state a vehicle operation restricted state A restricted communication system used when registering the store entry information Sdd in the mobile phone 3 with a key function by wireless communication and a lock state release request signal Sot for registering the vehicle operation restricted state are registered in the mobile phone 3 with a key function. The same communication system is shared with the release communication system used at the time. For this reason, it is not necessary to prepare individual communication parts in each communication system, and therefore the number of parts required for the communication system can be reduced.

(8) The drunk vehicle operation restriction system 33 is restricted on the mobile phone 3 side with the key function, but even in this case, the vehicle operation restriction state can be canceled on the key side without any problem.
(9) When the canceling function of the drinking water vehicle operation restriction system 33 is a numerical input type, memorization type, or puzzle type button operation input type, it is troublesome to release the vehicle movement restriction state of the drinking water vehicle movement restriction system 33. Since it is not necessary to go to the restaurant 34 and receive notification of non-drinking, it is convenient from this viewpoint. Moreover, even if the vehicle operation restriction system 33 during drinking is, for example, mischievously set in the vehicle operation restriction state, the restriction state can be canceled by operating the mobile phone 3 with a key function each time. Even if there is, it is hard to feel inconvenience in cancellation.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. Note that the second embodiment is a mechanism that restricts the engine start operation at the time of drinking on the mobile phone 3 side with a key function in the first embodiment, but only changes this on the vehicle 1 side. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and only different parts are described in detail.

  As shown in FIG. 17, the drunk vehicle operation restriction system 33 has an RF transmitter 60 installed in a restaurant parking lot 38 (dedicated parking lot) installed in a restaurant 34 (pub, bar, etc.). When the vehicle driver stops the vehicle at the restaurant parking lot 38 and stops at the restaurant 34, the RF transmission device 60 notifies the vehicle 1 to that effect and restricts various vehicle operations of the vehicle 1. System. Here, if the vehicle 1 is stopped at a restaurant parking lot 38 such as a pub or bar, it can be considered that there is a high possibility of drinking at the restaurant 34, so this is indirectly set by parking at the restaurant parking lot 38. Recognize as drinking behavior. The use restriction of the vehicle operation in this example is that even if the in-vehicle collation is established between the mobile phone 3 with the key function and the vehicle 1, the in-vehicle collation establishment is ignored if the in-vehicle collation is established, and the engine is started. Prohibited to start the engine is adopted.

  The drinking water vehicle operation restriction system 33 will be described below. The RF transmission device 60 includes a transmission control unit 61 that performs overall control of the RF transmission device 60, and an RF transmission unit 62 that modulates and outputs a signal in the RF band. It is a transmission unit with The RF transmitter 60 is installed, for example, at the entrance position of the restaurant parking lot 38, and periodically transmits the restaurant parking information Spk to the entire restaurant parking lot 38. The restaurant parking information Spk is an RF band signal in which a transmission area is set in accordance with the size of the parking lot, and the fact that the vehicle 1 is parked in the restaurant parking lot 38, that is, the driver of the vehicle is a tavern. In order to notify that there is a possibility of drinking at a bar or the like, it is a group of information for notifying information, a parking lot name, a parking time, and the like.

  On the other hand, the vehicle operation restriction program Dpr is written in the memory 22 of the verification ECU 4 as program data of the drunk vehicle operation restriction system 33 registered in the mobile phone 3 with a key function. The vehicle operation restriction program Dpr is program data having basically the same function as that registered in the communication control unit 18 described in the first embodiment. The vehicle operation restriction program Dpr of this example reads the content of the signal when the RF receiver 7 receives the RF signal, and restricts the engine start of the vehicle 1 when the received RF signal is the restaurant parking information Spk. This is a program to which a vehicle operation restriction function is assigned. The verification ECU 4 sequentially executes the vehicle operation restriction program Dpr separately from the formation of the communication areas E1 and E2 by the LF transmitters 5 and 6, and constantly monitors whether or not the vehicle 1 is parked in the restaurant parking lot 38. To do.

  When the restaurant ECU parking information Spk is received by the RF receiver 7 and the engine start is prohibited, the verification ECU 4 ignores the establishment of the indoor verification even if the in-vehicle verification is established with the mobile phone 3 with the key function. Thus, the state in which the indoor verification is not established, which does not allow the engine 24 to start, is taken. In addition, when the operation state becomes the room verification establishment neglected state, the verification ECU 4 is able to establish the transponder verification even if the transponder verification that is the ID verification with the transponder 30 in the mobile phone 3 with the key function is verified. ignore.

  Further, the drinking-time vehicle operation restriction system 33 of this example is also provided with a restriction state release function for returning the system that has entered the vehicle operation restriction state to the original normal state. As the restriction state release function, as shown in FIG. 17, in a restaurant 34 such as a pub or bar, non-drinker certification information Sok indicating that the person is a non-drinker is registered in the mobile phone 3 with a key function. A possible registration device 63 is provided. The registration device 63 operates when a start operation is performed, for example, when the signal transmission start button 63a is pushed by an employee of the restaurant 34, and notifies that the key holder is a non-drinker. Non-drinker certification information Sok is transmitted to a narrow area by an LF signal. When the registration device 63 transmits the non-drinker certification information Sok, if the mobile phone 3 with the key function enters the narrow area of the registration device 63, the mobile phone 3 with the key function wirelessly transmits the non-drinker certification information Sok. This is acquired by communication and registered in the memory 21. The registration device 63 automatically returns to the standby state when registration is completed or when a predetermined time has elapsed since activation. The registration device 63 constitutes a communication terminal, and the non-drinker certification information Sok constitutes a release permission notice.

  When the verification ECU 4 receives the ID signal Sid by the RF receiver 7 when the verification of the indoor verification is ignored, the verification ECU 4 checks whether or not the non-drinker certification information Sok is included in the ID signal Sid. At this time, if the non-drinker certification information Sok is not included in the ID signal Sid, the collation ECU 4 recognizes that the key holder at this time is a drunk person, and continues the state of neglecting the establishment of the indoor collation, and starts the engine. Maintain prohibited status. On the other hand, if the non-drinker certification information Sok is included in the ID signal Sid, the verification ECU 4 recognizes that the key holder at this time is a non-drinker, cancels the indoor verification establishment neglected state, and drinks The operation | movement which returns the vehicle operation | movement restriction | limiting system 33 to the original normal state is taken.

Next, the operation of the drunk vehicle operation restriction system 33 configured as described above will be described.
When the user drives the vehicle 1 and goes to the restaurant 34, when the user arrives at the parking lot 38 of the restaurant 34, the engine 1 is pushed to the parking frame of the parking lot 38 and the engine start switch 26 is pressed. The operating engine 24 is stopped. In the case of this example, since the RF transmission device 60 that transmits the restaurant parking information Spk is installed in the parking lot 38 of the restaurant 34 throughout the parking lot, when the vehicle 1 is parked in the parking lot 38, The vehicle 1 receives the restaurant parking information Spk. When the verification ECU 4 receives the RF signal by the RF receiver 7 and recognizes that the received signal is the restaurant parking information Spk, if the engine 24 is stopped at this time, the verification function ECU 4 Even if the in-vehicle collation is established, the in-car collation is neglected. That is, the drunk vehicle operation restriction system 33 enters the vehicle operation restriction state, and in this example, the engine start inhibition state in which the free engine start operation is prohibited.

  After the vehicle 1 is parked in the parking lot 38, the driver gets on the mobile phone 3 with the key function and gets off. After getting off the vehicle 1, the driver pushes the lock button 10 on the door handle knob 8 outside the driver's door and pushes the vehicle 1 Lock the door. Thereby, the vehicle 1 will be in a parking state (engine stop and door lock locked state). The driver (key holder) who gets off from the vehicle 1 enters the restaurant 34 and eats or drinks in the store.

  After eating and drinking in the store, the occupants including the key holders complete the payment in the store, but the store clerk of the restaurant 34 confirms whether or not the driver is a drinker at the time of the payment. At this time, if the driver is a drinker, the store clerk keeps the registration device 63 stopped or the key holder holds the mobile phone 3 with the key function over the detection surface of the registration device 63. Do not allow that. For this reason, the drinker cancels the in-vehicle verification establishment neglected state of the vehicle 1, that is, the non-drinker certification information Sok necessary for releasing the engine start prohibition state of the drunk vehicle operation restriction system 33 is displayed as a key function. Cannot register with the mobile phone 3.

  When the key holder returns to the vehicle 1 without registering the non-drinker certification information Sok in the mobile phone 3 with the key function, the mobile phone 3 with the key function enters the outside communication area E1 formed by the outside LF transmitter 5. In this case as well, outside-vehicle verification is performed between the mobile phone 3 with a key function and the parked vehicle 1 according to a normal format. The vehicle 1 at this time is in an in-vehicle verification establishment neglected state, but the establishment of the in-vehicle verification is accepted without any problem. Therefore, when the outside verification with the mobile phone 3 with a key function is established, the door lock is released. Allow lock. For this reason, when this operation is detected by the touch sensor 9 when the driver grips and operates the outside door handle knob 8 of the parked vehicle 1, the door lock is unlocked.

  Subsequently, the key holder performs an operation of opening and closing the driver's seat door and getting in the vehicle. When the verification ECU 4 detects the opening / closing operation of the driver's seat door by the courtesy switch 29, the verification ECU 4 at this time A request signal Srq is transmitted from the transmitter 6 to form a communication area E2 in the vehicle. At this time, if the mobile phone 3 with the key function is located in the in-vehicle communication area E2 formed by the in-vehicle LF transmitter 6, the mobile phone 3 with the key function returns the ID signal Sid in response to the request signal Srq. . When the driver is a drunk person, the non-drinker certification information Sok is not registered in the mobile phone 3 with the key function, so this ID signal Sid is signal data having only the ID code Cid that does not include the non-drinker certification information Sok. It is transmitted as.

  When the verification ECU 4 receives the ID signal Sid by the RF receiver 7 when the request signal Srq is transmitted from the in-vehicle LF transmitter 6, the ID code Cid of the mobile phone 3 with the key function acquired at this time and the ID of the vehicle 1 In-vehicle verification is performed against the code Cid. By the way, when the in-vehicle verification is established, for example, if the operation state of the vehicle is a normal state that is not in the in-vehicle verification ignored state, the engine is allowed to start. When the restaurant parking information Spk of the vehicle is received, the vehicle 1 is neglected in the in-vehicle verification, and therefore, if the non-drinker certification information Sok is not registered in the mobile phone 3 with the key function, the verification ECU 4 uses the ID code Cid. Even if they match, the in-vehicle verification is not allowed and the engine is not allowed to start. For this reason, even if a drinker pushes the engine start switch 26 to start the engine 24, the engine 24 cannot be started.

  Therefore, in this example, the RF transmitter 60 is installed in the parking lot 38 of the restaurant 34, and restaurant parking information Spk for prohibiting the engine start of the vehicle 1 is transmitted from the RF transmitter 60 to the entire parking lot. When the vehicle 1 receives the restaurant parking information Spk transmitted from the RF transmitter 60 when the vehicle 1 is parked in the parking lot 38, the vehicle 1 (verification ECU 4) receives the signal and the driver receives the signal. It is indirectly determined that alcohol has been drunk, and the operation state is set to an in-vehicle verification establishment neglected state, and free engine starting operation is prohibited. Then, the vehicle 1 takes the engine start prohibited state until the non-drinker certification information Sok indicating that it is not a drinker is registered in the mobile phone 3 with a key function, and does not allow the drinker to start the engine. For this reason, even if a drinker pushes and operates the engine start switch 26 to drive the vehicle 1, the engine 24 does not start, and drunk driving can be prevented.

  In addition, for the engine start prohibition, instead of a method of ignoring the in-vehicle collation, for example, a method may be used in which the collation ECU 4 does not accept a signal at the RF receiver 7 during the in-car collation. That is, when the vehicle 1 receives the restaurant parking information Spk of the RF transmitter 60, the collation ECU 4 at this time responds to the request signal Srq transmitted from the in-vehicle LF transmitter 6 and the mobile phone 3 with the key function Even if the ID signal Sid is sent back to the vehicle 1, an operation of not accepting the ID signal Sid is performed. For this reason, after all, the vehicle 1 does not take a state where the in-vehicle collation is established, and it becomes possible to prohibit the engineer from starting the engine as in the case where the in-vehicle collation is ignored.

  Further, when the vehicle 1 obtains the restaurant parking information Spk by wireless communication (narrow area communication) from a wireless communication device, this method is not limited to a method performed by installing a dedicated RF transmitter 60 in the parking lot 38. For example, as shown in FIG. 18, when the wireless LAN communication device 64 is mounted on the vehicle 1 and the public wireless LAN device 65 (hot spot (R)) is installed in the parking lot 38, the public wireless LAN When the wireless LAN communication device 64 receives the restaurant parking information Spk transmitted from the device 65, the vehicle 1 may be in a state in which in-vehicle verification is not established. Note that the narrow area communication of the wireless LAN communication is, for example, wireless communication using a frequency band of 2.4 GHz, and is a wireless communication method that is widely used regardless of vehicle relations.

  Furthermore, as a method other than this, since a vehicle 1 that can use an Intelligent Transport Systems (ITS) is equipped with a DSRC communication device 66 (Dedicated Short Range Communication communication device), it is wireless. Instead of the LAN communication device 64, a DSRC communication device 66 may be adopted. Furthermore, when the DSRC communication device 66 is mounted on the vehicle 1, road-to-vehicle communication for exchanging various types of information with a communication device on the road may be used as this communication, or from another vehicle 67. Vehicle-to-vehicle communication that receives various types of information may be used. The DSRC communication narrow-area communication is a vehicle-related dedicated wireless communication method using a frequency band of, for example, 5.8 GHz.

  The determination as to whether or not the vehicle 1 is located in the parking lot 38 is transmitted wirelessly from wireless communication devices (RF transmission device 60, wireless LAN communication device 64, DSRC communication device 66) installed in the parking lot 38. It is not limited to being performed by obtaining restaurant parking information Spk. For example, as shown in FIG. 18, when the vehicle position determination device 68 capable of determining the current position of the vehicle 1 is mounted on the vehicle 1, the current position information Sps of the vehicle 1 derived by the vehicle position determination device 68 is used. Thus, it may be determined whether or not the vehicle 1 is located in the parking lot 38. Examples of the vehicle position determination device 68 include a car navigation device 68a that guides the driver during driving and a G-Book device 68b that notifies the driver of store information such as restaurants while driving.

  The vehicle position determination device 68 has a GPS 69 that sequentially determines the current position based on various information obtained from the satellite, and outputs the current position information Sps derived by the GPS 69 to the verification ECU 4. When the verification ECU 4 obtains the current position information Sps from the vehicle position determination device 68, the vehicle 1 is compared with the vehicle position corresponding to the current position information Sps and the map map Mpp around the host vehicle, and the vehicle 1 is parked in the restaurant 34. It is determined whether it is located at 38 or not. When the verification ECU 4 recognizes that the vehicle 24 is in the parking state 38 of the restaurant 34 and the engine 24 is stopped in the position state, the verification ECU 4 sets the drunk vehicle operation restriction system 33 to the engine start prohibited state. Therefore, the in-vehicle verification is ignored.

  On the other hand, when a crew member including a key holder completes the checkout in the store, the store clerk of the restaurant 34 checks whether or not the driver is a drunk person. Since it is necessary to permit the cancellation of the engine start prohibition state of the drunk vehicle operation restriction system 33, the employee of the restaurant 34 permits the mobile phone 3 with a key function to be held over the registration device 63. At this time, if the registration device 63 is in the stopped state, the employee of the restaurant 34 activates the registration device 63 in the stopped state by, for example, pressing the signal transmission start button 63a of the registration device 63. The registration device 63 in the activated state transmits the non-drinker certification information Sok in a narrow area as a notification that the key holder is a non-drinker.

  After the registration device 63 is activated, when the key holder holds the mobile phone 3 with the key function over the detection surface of the registration device 63 and enters the communication area of the registration device 63, the mobile phone 3 with the key function is not drunk from the registration device 63. The user certification information Sok is received wirelessly, and this is written into the memory 21. When the mobile phone 3 with the key function receives the non-drinker certification information Sok from the registration device 63 and writes it in the memory, the mobile phone 3 with the key function displays the non-drinker certification information Sok on the screen 45 of the mobile phone 3. A message indicating that writing is in progress, for example, a character display such as “Loading ...” is performed. When the writing is normally completed, a completion notification is displayed on the screen 45, and when the writing is not successful, a re-execution notification is displayed on the screen 45.

  When the key holder registers the non-drinker certification information Sok in the mobile phone 3 with the key function and returns to the vehicle 1, the mobile phone 3 with the key function enters the outside communication area E1 formed by the outside LF transmitter 5. Even at this time, the outside verification is performed between the mobile phone 3 with a key function and the parked vehicle 1 as usual. When the outside vehicle collation is established at this time, the release of the door lock is permitted. Therefore, when the driver grasps the outside door handle knob 8 of the parked vehicle, the grasp operation is detected by the touch sensor 9. The door lock is unlocked.

  Subsequently, if the key holder opens and closes the driver's seat door and gets in the vehicle, the verification ECU 4 at this time transmits a request signal Srq from the vehicle LF transmitter 6 to form a communication area E2 in the vehicle. Thus, communication with the mobile phone 3 with a key function is attempted to be established. At this time, if the mobile phone 3 with the key function is located in the in-vehicle communication area E2 formed by the in-vehicle LF transmitter 6, the mobile phone 3 with the key function sends the ID signal Sid to the vehicle 1 in response to the request signal Srq. Move on to reply. When the ID signal is returned, if the non-drinker certification information Sok is registered in the cellular phone 3 with a key function (memory 21 of the communication control unit 18), the communication control unit 18 uses the ID code Cid unique to the key. The drinker certification information Sok is added, and this is transmitted as an ID signal Sid from the RF transmission unit 20 to the vehicle 1 by an RF band signal.

  When the ID signal Sid is received by the RF receiver 7, the verification ECU 4 reads various information included in the ID signal Sid (that is, the ID code Cid and the non-drinker certification information Sok). Here, if the ID code Cid included in the ID signal Sid does not match that of the vehicle 1, the verification ECU 4 recognizes that the in-vehicle verification is not established and does not allow the engine start in a form that follows a normal format. . On the other hand, when the verification ECU 4 confirms that the non-drinker certification information Sok is included in the same ID signal Sid when the ID code Cid included in the ID signal Sid matches that of the vehicle 1, If the own operation state is in the in-vehicle verification establishment neglected state, the in-vehicle verification establishment neglected state is canceled and the in-vehicle verification establishment is recognized as usual. That is, the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is released, and the engine can be freely started.

  Therefore, if the non-drinker certification information Sok is registered in the mobile phone 3 with the key function, the mobile phone 3 with the key function is set in the vehicle 1 when performing ID verification (in-vehicle verification) with the vehicle 1. The in-vehicle verification establishment neglected state is canceled, and the vehicle 1 returns to the normal state. Therefore, the drunk vehicle operation restriction system 33 is in the engine start permission state, so after entering the vehicle 1 after taking the procedure for registering the non-drinker certification information Sok in the mobile phone 3 with the key function, the shift lever is set to the parking position. When the engine start switch 26 is pushed while the brake pedal is depressed by the driver in the state of being positioned at, the engine 24 starts without any problem.

  In addition, as shown in FIG. 19, the non-drinker certification information Sok is registered in the mobile phone 3 with a key function by measuring the breath using an alcohol detector 50 installed in a parking lot 38 or the like to detect alcohol. If not, the breath measurement type in which the non-drinker certification information Sok is registered in the mobile phone 3 with a key function may be used. In the case of measuring the breath with the alcohol detector 50, the key holder performs an operation of blowing the breath to the detector 51 after starting the measurement of the alcohol detector 50, and the alcohol detector 50 detects the alcohol from the breath obtained at this time. If it is not measured, the non-drinker certification information Sok is transmitted to the mobile phone 3 with a key function by an LF band signal. When the mobile phone 3 with a key function receives the non-drinker certification information Sok transmitted from the alcohol detector 50 by the LF receiver 19, it writes this into the memory 21 and performs certification registration.

  Furthermore, the registration of the non-drinker certification information Sok to the mobile phone 3 with a key function starts up the operation input screens 46 to 48 shown in FIGS. 9 to 11 described in the first embodiment, and the predetermined button operation input is accurate. It may be possible to apply a method for determining whether or not registration is possible by confirming whether or not the registration has been performed. That is, when the operation input screens 46 to 48 shown in FIGS. 9 to 11 are launched on the screen 45 of the mobile phone 3 with a key function, the conditions given on the operation input screens 46 to 48 are as follows. If the operation button 44 is cleared, the non-drinker certification information Sok may be registered in the mobile phone 3 with a key function.

  Furthermore, when a portable device 70 having only a vehicle key function is used as shown in FIG. 20 instead of the cellular phone 3 with a key function as an electronic key, a cellular phone 71 without a key function (ie, When the non-drinker certification information Sok output from the registration device 63 is registered in the mobile phone 71) in which the ID code Cid of the vehicle 1 is not registered, the mobile phone 71 is used to cancel the in-vehicle verification establishment neglected state. It is also possible to use. In this case, the mobile phone 71 is used to release the in-vehicle verification establishment neglected state of the vehicle 1, and the door lock / unlock and engine start of the vehicle 1 are actually performed using the portable device 70. The mobile phone 71 constitutes a mobile terminal.

  Moreover, the cancellation of the in-vehicle verification establishment neglected state of the vehicle 1 may be performed on the vehicle 1 side, not on the mobile phone 3 with a key function. As an example thereof, as described in the first embodiment, for example, there is a method for determining whether or not the outside door handle knob 8 or the lock button 10 of the vehicle 1 is operated according to a predetermined procedure. When the verification ECU 4 confirms that the outside door handle knob 8 or the lock button 10 is operated in accordance with the determined procedure when the operation state is the vehicle verification establishment neglected state, the verification ECU 4 cancels the in-vehicle verification establishment neglected state and drinks alcohol. Return the hour vehicle operation restriction system 33 to the original normal state.

  Furthermore, when canceling the in-vehicle verification establishment neglected state of the vehicle 1 on the vehicle 1 side, this may be applied to a method in which the key owner clears the cancel operation input screens 46 to 48. That is, when one operation button in the vehicle is pushed, one screen of the release operation input screens 46 to 48 as shown in FIGS. 9 to 11 is displayed on the display 54 in the vehicle, and the conditions given on this input screen are as follows. Operate various operation buttons in the car and clear them in time. When the verification ECU 4 confirms that the release operation input screens 46 to 48 have been cleared, the verification ECU 4 cancels the in-vehicle verification establishment neglected state and returns the drunk vehicle operation restriction system 33 to the original normal state.

  The in-vehicle collation establishment neglected state of the vehicle 1 is a method in which the elapsed time after the vehicle 1 takes the established neglected state is counted, and is automatically canceled when the elapsed time exceeds a predetermined value and the time is up. Good. As an operation in this case, when the operation state becomes an in-vehicle collation establishment neglected state, the elapsed time after the collation ECU 4 enters this state is counted by a counter, a timer, etc., and when this elapsed time exceeds a predetermined value, the vehicle 1 cancels the in-vehicle verification establishment neglected state and cancels the engine start prohibition state of the drunk vehicle operation restriction system 33. In this example, it is also possible to display the remaining time from when the in-vehicle collation establishment neglected state is timed up to the released state on the in-vehicle display 54 or the screen 45 of the mobile phone 3 with a key function.

  Furthermore, the cancellation of the in-vehicle verification establishment neglected state of the vehicle 1 is not limited to the method in which the non-drinker certification information Sok is registered in the mobile phone 3 with a key function using the registration device 63 in the restaurant 34, as shown in FIG. As shown in FIG. 6, a method of directly registering the non-drinker certification information Sok in the vehicle 1 may be used. In this case, when the RF type release transmitter 72 capable of transmitting an RF signal to the entire parking lot 38 is provided outside the restaurant 34 and the employee of the restaurant 34 gives a proof of non-drinking to the customer, the RF type release transmitter 72 is provided. This is performed by transmitting a release notification signal Sor including the ID code Cid of the vehicle 1 and the non-drinker certification information Sok from the transmitter 72 as a signal in the RF band. In this example, among the plurality of parked vehicles 1, those having the same ID code Cid receive the release notification signal Sor, and the in-vehicle collation establishment neglected state of the vehicle 1 is released. Moreover, when outputting non-drinker certification | authentication information Sok from the alcohol detector 50 by the same view as this, you may cancel | release the restriction | limiting state of the vehicle 1 by sending this directly to the vehicle 1. FIG.

According to this embodiment, in addition to the various effects described in the first embodiment, the following effects can be obtained.
(10) Even if the vehicle operation restriction system 33 at the time of drinking has a system configuration that is restricted on the vehicle 1 side, the vehicle operation restriction state of the vehicle operation restriction system 33 at the time of drinking can be released without any problem on the key side.

  (11) When cancellation of the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is performed by the non-drinker certification information Sok to the mobile phone 3 with the key function, the vehicle 1 parked in the parking lot 38 is the driver. However, since it cannot be moved until the non-drinker certification information Sok is registered in the mobile phone 3 with a key function, the present system can be used instead of a time-rented parking lot.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
In the first and second embodiments, the electronic key (portable terminal) is not limited to the cellular phone 3 with the key function in which the cellular phone is equipped with the electronic key function. A portable device that performs collation or a wireless key that transmits a lock request or an unlock request to the vehicle 1 together with the ID code Cid when a button operation is performed may be used.

  In the first embodiment, when the use restriction is applied to the mobile phone 3 with the key function and the drinking water vehicle operation restriction system 33 is set to the vehicle operation restriction state, the use restriction applied to the mobile phone 3 with the key function at this time is ID Any method may be used as long as the verification is not established. Note that this can also be said similarly when the use restriction is applied to the vehicle 1 in the second embodiment to place the drinking-time vehicle operation restriction system 33 in the vehicle operation restriction state.

  -In 1st and 2nd embodiment, the vehicle operation | movement limitation system 33 which restrict | limits the vehicle operation at the time of drinking to the vehicle 1 does not necessarily restrict | start an engine, for example, restrict | limits door lock locking / unlocking and makes a drinker in a vehicle It is also possible to use a method of not entering. That is, various methods may be used as long as the drunk person cannot drive the vehicle.

  In the first embodiment, the LF transmitter 35 is not limited to constantly transmitting the restaurant entry information Sdd, and for example, a sensor for detecting the passing of a visitor is provided near the door of the restaurant 34, and the customer uses this sensor. A system may be used in which restaurant entry information Sdd is transmitted several times when a store entry is detected. In addition, it cannot be overemphasized that this can be utilized for the transmission system at the time of RF transmission apparatus 60 transmitting the restaurant entrance information Sdd in 2nd Embodiment.

  -In 1st and 2nd embodiment, even if it utilizes various systems, if the driver | operator can prove that the driver | operator is not a non-drinker, cancellation | release of the vehicle operation | movement restriction | limiting state of the vehicle operation | movement restriction | limiting system 33 at the time of drinking Good.

  In the first and second embodiments, when canceling the vehicle operation restriction state of the drunk vehicle operation restriction system 33, an accurate release operation input (numerical value input type, memorization type, puzzle type) on the mobile phone 3 with a key function ID verification between the mobile phone 3 with a key function and the vehicle 1 when the two conditions of the ID input between the vehicle 1 and the mobile phone 3 are established. For example, the activation of the release application on the mobile phone 3 with the key function may be permitted only when the vehicle exterior verification is established.

  In the first embodiment, the installation location of the LF transmitter 35 is not necessarily limited to the restaurant 34. For example, the LF transmission device 35 may be installed in a place where there is a possibility of performing a drinking operation such as a liquor store or a liquor vending machine. It may be. This is also true for the RF transmitter 60 in the second embodiment.

  -In 1st and 2nd embodiment, the collation communication system used at the time of key collation, the restriction | limiting communication system used when the vehicle operation | movement restriction | limiting system 33 at the time of drinking are made into a vehicle operation restriction | limiting state by radio | wireless communication, vehicle operation at the time of drinking The cancellation communication system used when canceling the vehicle operation restriction state of the restriction system 33 by wireless communication is not necessarily limited to using the same communication system. For example, these communication systems may be provided separately. Needless to say, various communication systems (frequency band, modulation system) can be used as communication systems used in these communication systems.

  In the second embodiment, when the vehicle operation is restricted on the vehicle 1 side and the restriction release is performed in a time-up manner, for example, the elapsed time after the vehicle 1 enters the vehicle operation restricted state is expressed as the cellular phone 3 with a key function. When the mobile phone 3 with the key function confirms that the time is up, the vehicle 1 may be notified to that effect and the vehicle operation restriction state of the vehicle 1 may be released.
