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, for example, Patent Documents 1 and 2.

  By the way, this type of alcohol detector that actually takes in exhaled air and measures the amount of alcohol in the exhaled air requires a plurality of types of components such as an exhalation inlet and a sensor as its component parts. There are parts that require a certain size. Therefore, there is a concern that the drunk driving prevention system using this type of alcohol detector may become large as a result, and there is a problem in that the arrangement space when mounted on the vehicle, the interior design of the vehicle, and the like are limited. In particular, in the future, if it is required to have a drunk driving prevention system in the vehicle, it is not desirable to install such a large system even in the vehicle of a person who does not drink, so some countermeasures are strongly desired . Further, even if a drunk driving prevention system is mounted on a vehicle, a system that does not require addition of many parts to the vehicle has been desired so that the conventional vehicle can be used almost as it is.

  An object of the present invention is to provide a drunk driving prevention system that does not require a large system structure and that does not require many parts to be added to the vehicle.

In order to solve the above problems, the present invention uses an electronic key for short range transmitting the key-specific key code by radio, a key code the registered key code and vehicles originating from the electronic key performs key verification by collating the in drunk driving prevention system for use in the vehicle with an electronic key system that allows various vehicle operation on condition of success of the key verification, provided at a position of the drinking Friendly, the A drinking information output means for wirelessly outputting to the electronic key drinking information for notifying that the user has stopped at a location; and the electronic key is provided with the drinking information output means , and the driver acquires the drinking information. whether the determination, and indirectly determines drink determining means using said drinking information, when the drinking determining means determines that drinkers the driver, the electronic key In the vehicle operating limit state in an equivalent system key side by adding a use restriction, and summarized in that and a limiting means to limit the vehicle operation.

  According to this configuration, the drinking determination means for determining whether or not the driver is a drinker is provided on the key side (electronic key side), and the drinking determination means acquires the drinking information output from the drinking information output means. The determination means determines whether or not the driver is a drinker on the key side using the drinking information as a determination material. If it is determined that the driver is not a drinker at this time, the restricting means does not restrict the use of the electronic key and does not operate the drunk driving prevention system. On the other hand, when the drinking determination means determines that the driver is a drinker, the restriction means places a use restriction on the electronic key to place the drunk driving prevention system in a vehicle operation restricted state, thereby disallowing free vehicle operation. For this reason, when the driver has drunk, the engine cannot be started freely, so that drunk driving of the vehicle can be prevented.

  Also, in this configuration, the drinking information output from the drinking information output means is received with an electronic key, and the presence or absence of drinking is indirectly determined with the electronic key using this drinking information. When mounting, for example, it is not necessary to mount a large alcohol detector on the vehicle. For this reason, it is possible to determine whether or not to drink and to limit vehicle operation in a small-scale system that is not large. Further, although the vehicle operation is restricted when the driver is a drinker, since this restriction is performed on the key side, it is not necessary to mount several kinds of functional parts on the vehicle. Therefore, since it is not necessary to add various parts to the vehicle, no major changes are made to the vehicle used so far.

The gist of the present invention is that the drinking information output means periodically wirelessly transmits the drinking information at the drinking allowed position .

  According to this configuration, since the drinking information output of the drinking information output means is performed in conjunction with one operation in the process of the driver's drinking behavior, for example, a dedicated operation for registering the electronic key in the drinking information output means Is unnecessary, it is difficult to create trouble and trouble in registering drinking information in the electronic key.

  In the present invention, the drinking determination means is a notification formula that makes a drinking determination by checking whether or not a drinking notice as drinking information that is output as a drinking presence / absence notification is received from the drinking information output means. The gist.

  According to this configuration, when the drinking determination unit determines whether or not the driver is drinking, the driver's drinking determination is determined by checking whether or not the electronic key has received the drinking notification output from the drinking information output unit. Therefore, it is possible to determine whether or not the driver is drinking by a simple determination process of checking whether or not a drinking notice is received.

  In the present invention, when the payment determination function is added to the electronic key, the drinking determination means is the payment information as the drinking information output from the drinking information output means that works as a communication partner of the electronic key at the time of payment. It is a summary that it is a settlement type that determines whether or not the driver is a drinker from the contents of the settlement information.

  According to this configuration, when the drinking determination unit determines whether or not the driver is drinking, the electronic key is acquired from the payment device when the driver uses the electronic key payment function to pay for food and drink. The driver determines whether or not he / she is drinking by deciphering the contents of the payment information. For this reason, when the driver actually drinks, the fact that it is described in the payment information, if you adopt a method to determine whether the driver drinks or not from the payment information, more accurately the presence or absence of drinking Can be determined.

The gist of the present invention is that it comprises selection means capable of selectively determining whether or not the drinking information is transmitted from the drinking information output means.
According to this configuration, since the selection means for selecting and specifying whether or not to send the drinking information from the drinking information output means is provided, if the driver is a drinker, the drinking information output means outputs the drinking information and the driving If the person is a non-drinker, it is possible to prevent the drinking information output means from outputting drinking information. Therefore, if the drinking information is output from the drinking information output means only when the driver recognizes that he / she is a drinker, the situation where the drinking information is registered in the electronic key of the non-drinker hardly occurs. Thus, accuracy in registering drinking information in the electronic key is increased.

  In the present invention, when the drinking determination unit determines that the driver is a drinker, the restriction unit activates the electronic key, but the electronic key accepts a request for key code transmission from the vehicle. However, the gist is to limit the vehicle operation by causing the electronic key to take a state in which the key code is not returned to the vehicle.

  According to this configuration, when the drinking determination unit determines that the driver is a drinker, the electronic key does not return a key code in response to receiving a key code return request from the vehicle. Add restrictions to vehicle operation. For this reason, for example, even if the electronic key is in a use-restricted state, the electronic key at this time maintains the activated state. For example, this type of electronic key has a key function that adds a key function to a mobile phone. Even in the case of a mobile phone, the telephone function can be continuously used even when the key is in a use restriction state.

  In the present invention, when the drinking determination unit determines that the driver is a drinker, the restriction unit limits the vehicle operation when the electronic key receives a request for key code transmission from the vehicle. And adding a vehicle operation restriction request, which is a notification to the effect, to the key code and causing the electronic key to take an action of returning the key code to the vehicle, thereby adding a restriction to the vehicle operation. To do.

  According to this configuration, when the drinking determination means determines that the driver is a drinker, when the electronic key receives a key code transmission request from the vehicle, the vehicle returns the vehicle with a key code unique to the key. By adding an operation restriction request to the key code and transmitting it to the vehicle, the vehicle operation is restricted. For this reason, when the vehicle operation is restricted on the key side, the vehicle operation restriction is performed by a simple process of transmitting a data group in which the vehicle restriction request is added to the key code to the vehicle at the time of key collation with the vehicle. It becomes possible.

  In the present invention, when the drinking determination unit determines that the driver is a drinker, the restriction unit is not an accurate key code when the electronic key receives a request for key code transmission from the vehicle. The gist of the invention is to limit the vehicle operation by causing the electronic key to perform an operation of returning a false code to the vehicle.

  According to this configuration, when the drinking determination unit determines that the driver is a drinker, the operation state of the electronic key is changed to an operation state in which a false code is returned to the vehicle when a request for a key code return is received from the vehicle. To limit the vehicle operation. Therefore, when notifying the vehicle from the electronic key to the vehicle so as to limit the vehicle operation on the key side, for example, in the case of a method of notifying information on the key code on the key code, Although the data amount is excessively increased by the amount of the notification information, this configuration is not a method for carrying this type of notification information, so that the notification can be notified with a small amount of data.

  The gist of the present invention is that the restricting means restricts the vehicle operation by forcibly turning off the power source of the electronic key when the drinking determination means determines that the driver is a drinker. To do.

  According to this configuration, when the drinking determination unit determines that the driver is a drinker, the vehicle operation is restricted by forcibly shutting off the power source of the electronic key, so that the driver is determined to be a drinker. Under such circumstances, the electronic key does not operate at all, and the electronic key in the power-off state cannot be used as a key. For this reason, since any kind of vehicle operation cannot be performed even if this electronic key is used, drunk driving can be more reliably prevented.

  In the present invention, when the drinking determination unit determines that the driver is a drinker, the limiting unit performs outputting the key code in a manner to limit the vehicle operation for a certain period of time. The gist of the present invention is to put the system into a vehicle restricted state during the predetermined time.

  According to this configuration, when the drinking determination means determines that the driver is a drinker, the restriction means places a restriction on the vehicle operation, but this restriction is added only for a certain period of time. After the vehicle restriction state is released, various vehicle operations can be freely performed as before.

  In the present invention, the electronic key system performs engine start system key verification between the electronic key and the vehicle in the vehicle as key verification required when starting the engine, and if the engine start system key verification is established. The free engine start of the vehicle is permitted, and the restricting means restricts the key code to the vehicle operation at the time of the engine start system key collation when the drinking determination means determines that the driver is a drinker. The gist is to limit the starting of the engine by outputting in an adding manner.

  According to this configuration, since the engine start is restricted when the drinking determination means determines that the driver is a drinker, for example, if the driver is a drinker, the drinker gets on the vehicle and starts the engine. Even if you do, you don't have to let the drinker start the engine at this time. Therefore, the situation where the engine starts by the engine start operation by the drinker is less likely to occur, and the situation where the drunk driving occurs can be further prevented.

  In the present invention, the verification communication system used when performing the key verification in the electronic key system and the limited communication system used when performing the wireless operation when limiting the vehicle operation restriction state are the same communication. The gist is that the system is used.

  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.

  According to the present invention, it is possible to provide a drunk driving prevention system that does not require a large system structure and that does not require many parts to be added to the vehicle.

Hereinafter, an 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 an electronic key system and a drunk driving prevention system. The mobile phone 3 with a key function corresponds to an electronic key, and the ID code Cid corresponds to a 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.

  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.

  Further, 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 using 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 in accordance with 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.

  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 door handle knob 8 outside the vehicle 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. The indoor verification corresponds to engine start system key verification.

  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 verification 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 casing 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 an electronic 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 constitutes a drunk driving prevention system, and the LF transmitter 35 constitutes a drunk information output means. The restaurant entry information Sdd constitutes drinking information and drinking notification.

  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.

  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. In addition, the vehicle operation restriction program Dpr of this example is a notification formula that makes a drinking determination by checking whether or not the mobile phone 3 with a key function has received the restaurant entry information Sdd from the LF transmitter 35. Note that the vehicle operation restriction program Dpr is also written in the memory 22 of the vehicle 1 if the operation determination of the drinking-time 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. Note that the communication control unit 18 and the vehicle operation restriction program Dpr constitute drinking determination means and restriction means.

  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 start up 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. The transmission operation device 39 constitutes a selection unit.

  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 a 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. You may use the payment type | formula on the condition that payment was performed in 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. The payment terminal 42 constitutes drinking information output means.

  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 payment notification Smn is acquired from the payment terminal 42, the store name, the store system, the order menu, etc. obtained from the payment notification Smn are viewed, and it is confirmed whether or not the store where the restaurant was eaten at this time is a pub or 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 system structure that locks to the ID signal transmission of the mobile phone 3 with the key function using the settlement notification Smn is used, if the payment terminal 42 is installed in the restaurant 34 in advance, 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 settlement notification Smn, it leads to an advantage that the parts cost of the drunk vehicle operation restriction system 33 can be kept low. The payment notification Smn constitutes drinking information and payment information.

  Furthermore, even when the mobile phone 3 with a key function is restricted using the settlement notification 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, a determination operation device 43 that can add a non-drinker notification Snd indicating that the payer is not a drinker to the settlement notification Smn is provided in the payment terminal 42. 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 a settlement notification Smn to the mobile phone 3. This non-drinker notification Snd is added and this composite information Stt (settlement notification Smn and non-drinker notification Snd) is registered in the mobile phone 3 so that the mobile phone 3 with a key function is not in the in-vehicle verification ID signal transmission lock state. To do. The determination operation device 43 constitutes a selection unit.

  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. The engine start restriction request Seg corresponds to a vehicle operation restriction request.

  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.

  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 the 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.

  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 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.

  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 as an RF band signal outside the restaurant 34. An out-of-store release device 56 capable of transmitting is attached. Then, the restaurant 34 side acquires the ID code Cid of the vehicle 1 of the visitor in advance, and when the employee determines that the driver is not a drinker at the time of payment on the way home, the vehicle 1 of the non-drinker The cancellation notification signal Sob including the ID code Cid is transmitted from the out-of-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 LF transmitter 35 capable of transmitting the restaurant entry information Sdd by a signal in the LF band is installed in the restaurant 34, and when the key holder enters the restaurant 34, the mobile phone 3 with the key function is By checking whether or not the restaurant entrance information Sdd is received, it is indirectly determined whether or not the driver is drinking, and when it is determined that there is drinking, the ID signal transmission of the mobile phone 3 with the key function is locked. Prohibit engine starting. For this reason, since the engine 24 cannot be started when the driver is a drunk person, drunk driving can be prevented. Further, whether or not the driver drinks alcohol is determined based on an indirect view of whether or not the mobile phone 3 with a key function receives the restaurant entry information Sdd. It is not necessary to attach an alcohol detector as a device to the vehicle 1, and the system scale of the drunk vehicle operation restriction system 33 can be made as small as possible. Furthermore, when the use restriction is applied to the vehicle operation, the use restriction is performed on the key side, so that it is not necessary to mount a number of such functional parts on the vehicle 1. Therefore, since it is not necessary to add various parts to the vehicle 1, it is necessary to make a major change to the vehicle 1 that has been used so far, even when the vehicle operation restriction system 33 during drinking is installed in the vehicle 1. Nor.

  (2) When the mobile phone 3 with a key function receives the restaurant entry information Sdd transmitted from the LF transmitter 35, when it is determined that there is drinking and the vehicle operation is restricted, the mobile phone with a key function Registration of the restaurant entry information Sdd to 3 is performed in conjunction with a process of drinking that a key holder opens the door of the restaurant 34 and enters the store. For this reason, when the key owner enters the restaurant 34, the employee does not bother to register the restaurant entry information Sdd in the mobile phone 3 with the key function. It can be omitted. The same applies to the case where the driver determines whether or not he / she is drinking using the payment notification Smn obtained when the mobile phone 3 with a key function makes a payment.

  (3) When the mobile phone 3 with a key function receives the restaurant entry information Sdd transmitted from the LF transmitter 35, when it is determined that there is drinking and the vehicle operation is restricted, the mobile phone with a key function It is possible to determine whether or not the driver has drunk in a simple manner in which 3 shows whether or not the restaurant entry information Sdd has been received.

  (4) When payment is completed with the mobile phone 3 with a key function, when determining whether or not the key holder is drinking using the payment notification Smn acquired by the mobile phone 3 with the key function, Since alcoholic beverages are included in the drink, it is possible to more accurately determine whether or not the key holder has drunk by using the settlement notification Smn to determine the presence or absence of drinking.

  (5) When the transmission operation device 39 capable of selectively operating the transmission of the restaurant entrance information Sdd is provided in the LF transmission device 35, when the driver is a drunk person, the transmission operation device 39 is signal-transmitted and the LF is transmitted. By sending the restaurant entry information Sdd from the transmission device 35, the restaurant entry information Sdd is registered in the mobile phone 3 with a key function to restrict the vehicle operation, and when the driver is a non-drinker. The restaurant operation information 39 is not transmitted from the LF transmission device 35 without operating the signal transmission operation of the transmission operation device 39, and the vehicle operation is performed without registering the restaurant entry information Sdd in the mobile phone 3 with the key function. The action is taken without any restrictions. For this reason, the situation where the restaurant entry information Sdd is registered in the mobile phone 3 with the key function of the non-drinker does not occur, and the situation where the vehicle operation is restricted to the vehicle 1 of the non-drinker does not occur. Can do.

  (6) When the vehicle operation is restricted by locking the ID signal transmission of the mobile phone 3 with the key function, the mobile phone 3 with the key function cannot transmit the ID signal Sid, and other functions are normal. Take the operating state. For this reason, even when the driver is a drunk person and locks the ID signal transmission of the mobile phone 3 with the key function to restrict the engine start, the ID signal transmission of the mobile phone 3 with the key function is taken. Other functions other than can be used continuously.

  (7) When the mobile phone 3 with a key function transmits the ID signal Sid, the engine start restriction request Seg for notifying that the engine start is restricted is returned to the vehicle 1 together with the ID code Cid to restrict the vehicle operation. , The vehicle 1 can be restricted by a simple process of adding this kind of restriction request to the ID signal Sid.

  (8) When the mobile phone 3 with a key function performs ID collation with the vehicle 1 to limit the vehicle operation by returning a false code to the vehicle 1, for example, an engine start restriction request Seg to the ID code Cid When using a method that restricts the vehicle operation by putting a vehicle, the amount of outgoing data will increase by the required data, but in this example, only the data for the fake code is needed. The amount of outgoing data sent to the vehicle 1 is small.

  (9) When the vehicle operation is restricted by performing the power shutdown of the mobile phone 3 with the key function, the mobile phone 3 is not moved at all in a situation where the driver is determined to be a drinker. . Therefore, in a situation where the driver is determined to be a drunk person, no vehicle operation can be performed using the mobile phone 3 with a key function, so drunk driving can be prevented more reliably.

  (10) 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.

  (11) When the driver is treated as a drinker, the engine start is prohibited as a vehicle operation restriction. In this case, the engine start itself is not permitted. can do.

  (12) A key communication function for wirelessly communicating restaurant entrance information Sdd from the LF transmitter 35 and a verification communication system used when performing wireless ID verification between the vehicle 1 and the mobile phone 3 with a key function in the hands-free system 2 The same LF band communication system is shared with the restricted communication system used when registering to the attached mobile phone 3. 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.

  (13) When the canceling function of the drinking water vehicle operation restriction system 33 is a numerical value input type, memorization type, or puzzle type button operation input type, it is bothered to release the vehicle movement restriction state of the drinking water vehicle operation 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.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
-The electronic key is not limited to the cellular phone 3 with the key function in which the cellular phone is equipped with the electronic key function. For example, a portable device having only the key function and automatically collating ID with the vehicle 1 or a button operation is performed. The wireless key may be transmitted to the vehicle 1 together with the ID code Cid when the locking request or the unlocking request is issued.

  -When the use restriction is applied to the mobile phone 3 with the key function and the vehicle operation restriction system 33 for drinking is set to the vehicle operation restriction state, the use restriction applied to the mobile phone 3 with the key function at this time must be ID verification. Any method may be used.

  The vehicle operation in which the drunk vehicle operation restriction system 33 restricts the use of the vehicle 1 is not necessarily limited to the engine start, but may be a system in which, for example, the door lock locking / unlocking is restricted to prevent the drinker from entering the vehicle. That is, various methods may be used as long as the drunk person cannot drive the vehicle.

  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's entrance is detected by this sensor. Sometimes, a method of transmitting restaurant entry information Sdd several times may be used.

-The cancellation | release of the vehicle operation restriction | limiting state of the vehicle operation | movement restriction | limiting system 33 at the time of drinking may use various systems, if it can prove that the driver is not a non-drinker.
-When canceling the vehicle movement restriction state of the drinking water vehicle movement restriction system 33, an accurate release operation input on the mobile phone 3 with a key function (numerical input type, memorization type, puzzle type or other button operation input type accurate ID verification between the vehicle 1 and the mobile phone 3 is established, and ID verification (for example, vehicle verification) is established between the mobile phone 3 with a key function and the vehicle 1. Only occasionally, activation of the release application on the mobile phone 3 with a key function may be permitted.

  -The installation location of the LF transmitter 35 is not necessarily limited to the restaurant 34. For example, the LF transmitter 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, or the vehicle operation may be in a restricted state with the purchase of liquor.

  The verification communication system used at the time of key verification, the limited communication system used when the vehicle operation restriction system 33 during drinking is set to the vehicle operation restriction state by wireless communication, and the vehicle operation restriction state of the vehicle operation restriction system 33 during drinking The cancellation communication system used when canceling by wireless communication is not necessarily limited to using the same communication system, and 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.

  The restriction communication system used when the drunk vehicle operation restriction system 33 is in the vehicle operation restriction state and the release communication system used when the drunk vehicle operation restriction system 33 is released from the vehicle operation restriction state are not necessarily wireless. It is not limited to communication. For example, a method may be adopted in which a connection connector is provided in a communication device that is a communication destination of the mobile phone 3 with a key function, and data communication is performed by wired communication by setting the mobile phone 3 to the connector.

  -The condition necessary for canceling the vehicle operation restriction state of the drunk vehicle operation restriction system 33 is not necessarily one. For example, all three of the numerical input type, the memorization type, and the puzzle type shown in FIGS. A plurality of release conditions may be combined so that the release is permitted only when it can be cleared.

  ・ When the button operation input type that requests an accurate release operation input with the mobile phone 3 with a key function is used as a release method of the vehicle operation restriction state of the drinking vehicle operation restriction system 33, the time limit at this time is appropriately changed. It can be changed depending on, for example, age, sex, and individual differences. When this type of release method is used, when the mobile terminal is a portable device or a wireless key, the release condition may be to press various buttons (lock button or unlock button) of the mobile terminal in a predetermined order.

  The key system is not necessarily limited to an electronic key system in which a unique code of a key is collated by wireless communication. For example, a mechanical key system using a mechanical key may be used.

The determination as to whether or not the driver has entered the restaurant 34 may be performed using position information obtained from the GPS if the mobile phone 3 is equipped with a GPS function, for example.
The settlement function 41 is not limited to the one using a dedicated communication method, and for example, the LF communication used for key verification may be shared.

The target for mounting the drunk vehicle operation restriction system 33 is not necessarily limited to a passenger car, but may be a motorcycle, for example.
