Description

  The present invention relates to a vehicular remote control device that remotely controls an in-vehicle device on a vehicle side using a portable device.

  Conventionally, a wireless signal transmitted by a user operating a switch of a portable device (key) is received on the vehicle side, and an ID code included in the wireless signal is compared with an ID code registered on the vehicle side, 2. Description of the Related Art A remote control device for a vehicle that locks or unlocks a door lock of a vehicle when verification is confirmed is widely known.

In recent years, two-way communication is performed between the transceiver on the vehicle side and the portable device by weak radio waves, and the approach of a legitimate user to the vehicle is detected by confirming the ID code of the portable device. A remote control device for a vehicle that releases a door lock of the vehicle simultaneously with detection of an operation has been proposed. In this type of vehicular remote control device, if the user has a portable device, the switch operation of the portable device becomes unnecessary, and convenience is improved. However, this type of vehicle remote control device eliminates the need for a switch operation of the portable device and improves convenience, but has the disadvantage that locking or unlocking the door lock can be realized against the user's intention. Conventionally, various proposals have been made to improve this point (for example, see Patent Document 1).

  ADVANTAGE OF THE INVENTION According to this invention, the operation of a some vehicle is possible with one portable machine, and the remote control apparatus for vehicles which a vehicle contrary to the intent does not respond by operation of the said one portable machine can be obtained.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a system configuration diagram showing an embodiment of a vehicle remote control device according to the present invention. The vehicle remote control device according to the present embodiment includes a portable device (key) 20 possessed by a user. The portable device 20 has a function of transmitting a predetermined response signal in response to the request signal when receiving the request signal transmitted from the transceiver 30 mounted on the vehicle. This response signal includes a first ID code assigned to the portable device 20 in advance. Hereinafter, the two-way communication with the vehicle realized by the communication function of the portable device 20 is referred to as “smart communication”, and the first ID code is referred to as “smart ID”.

  The portable device 20 includes a switch 21 that can be operated by the user. The portable device 20 has a function of transmitting a predetermined command signal in response to the operation of the switch 21 by the user. This command signal includes a command for requesting locking or unlocking of the door lock, and similarly includes a second ID code assigned to the portable device 20 in advance. Hereinafter, the one-way communication with respect to the vehicle realized by the communication function of the portable device 20 is referred to as “wireless communication”, and the second ID code is referred to as “wireless ID”.

  The vehicle-side transceiver 30 is disposed at an appropriate position of the vehicle (for example, a door of the vehicle) and is connected to an electronic control device 32 mounted on the vehicle. The electronic control device 32 may be a microcomputer including a CPU, various memories, and the like, and predetermined registration data is stored in the memory together with various programs executed by the CPU. The registration data stored in the memory includes ID codes respectively corresponding to the smart ID and the wireless ID.

  Hereinafter, for the sake of explanation, the smart ID and wireless ID assigned to the portable device 20 side will be referred to as the portable device side smart ID and wireless ID, and the smart ID and wireless ID registered on the vehicle side corresponding to these will be described. It is called a vehicle-side smart ID and a wireless ID. These IDs may be any codes as long as they correspond one-to-one on the portable device side and the vehicle side.

  The electronic control device 32 performs verification of the ID code included in the signal sent from the portable device 20 based on the ID code included in the registration data, and performs various controls according to the verification result. For example, at the time of the above-described wireless communication, the electronic control device 32 collates the portable device side wireless ID included in the command signal transmitted from the portable device 20 with the vehicle side wireless ID included in the registration data. As a result of this collation, when both wireless IDs match, the electronic control device 32 executes predetermined control according to the command content included in the command signal. That is, the electronic control device 32 sends a control signal to the door lock actuator, and realizes the command content (for example, locking or unlocking the door lock) included in the command signal. On the other hand, when both wireless IDs do not match, the electronic control device 32 does not perform predetermined control or generates an alarm. Thus, the ID code given in advance to the vehicle side and the portable device 20 side plays an important role of ensuring the legitimate use of the vehicle by the legitimate user. Therefore, from this point of view, an individual ID code is assigned to each vehicle.

  In this embodiment, in the registration data, in addition to the individual ID codes (smart ID and wireless ID) given in advance for each vehicle as described above, another smart ID can be newly registered. The registration of this new different smart ID is an operation to be executed by the legitimate user himself or under the approval thereof. From this point of view, the additional registration of the smart ID may be designed so that only the person who has the master key or the dealer can do it.

  Next, the operation of the vehicle remote control device of this embodiment will be described in detail with reference to FIG. Here, it is assumed that a legitimate user of the two vehicles 1 and 2 has the portable device 20 for the vehicle 1 and approaches the adjacent vehicles 1 and 2. In this example, it is assumed that the smart ID 1 related to the vehicle 1 is registered in the memory of the electronic control device 32 of the vehicle 2 in addition to the smart ID 2 and wireless ID 2 related to the vehicle 2 that are initially assigned.

  In this situation, request signals are periodically transmitted from the transceivers 30 of the two vehicles 1 and 2 toward a predetermined area. The request signal may be transmitted using, for example, 125 to 134 kHz as a use band, and may be given a strength such that the communication distance with the transceiver 30 is about several meters. The request signal from the transceiver 30 of the vehicle 1 includes the smart ID 1, but the request signal from the transceiver 30 of the vehicle 2 includes the smart ID 1 in addition to the smart ID 2.

  The portable device 20 for the vehicle 1 receives both of these request signals, but since each request signal includes the smart ID 1, it responds to any request signal and A wireless signal (response signal) including the smart ID 1 assigned to is transmitted. The response signal may be transmitted with a predetermined transmission power (transmission power sufficiently larger than the request signal) using, for example, the vicinity of 300 MHz as a use band. After the received response signal is subjected to predetermined processing such as amplification and demodulation, the response signal is supplied to the electronic control unit 32.

  Here, the electronic control device 32 of the vehicle 1 collates the smart ID 1 included in the supplied response signal with the smart ID 1 set and stored in advance, so that the portable device 20 (user) having the valid smart ID 1 ) Is detected to approach the vehicle. The electronic control unit 32 detects a predetermined operation intended to open the door by the user within a predetermined time after detecting the approach of the legitimate user to the vehicle (for example, disposed on the door outer handle). In the case of detection by a touch sensor), at the time of detection, a control signal is sent to a door lock actuator that drives a door lock mechanism of a predetermined door to realize unlocking of the door lock. As a result, a user who has a legitimate portable device 20 takes out the portable device 20 and inserts it into the key cylinder or opens the desired door and enters the vehicle 1 without operating the switch 21 of the portable device 20. Can do.

  On the other hand, the electronic control device 32 of the vehicle 2 similarly collates the smart ID 1 included in the response signal transmitted from the portable device 20 for the vehicle 1 with the smart ID in the registration data. In this case, as described above, since the smart ID 1 is stored in addition to the smart ID 2 in the registration data of the electronic control device 32 of the vehicle 2, the electronic control device 32 includes the portable device 20 having the valid smart ID 1. The approach of the (user) to the vehicle is detected. Similarly, the electronic control device 32 detects a predetermined operation intended to open the door by the user within a predetermined time after detecting the approach of the legitimate user to the vehicle (for example, arranged on the door outer handle). In the case of detection by a touch sensor provided, at the time of detection, a control signal is sent to the door lock actuator to unlock the door lock. Therefore, even if the user does not have the portable device 20 for the vehicle 2, if the user has the portable device 20 for the vehicle 1, the user can open the desired door and get into the vehicle 2.

  On the other hand, the case where the user operates the switch 21 (the door opening command switch) of the portable device 20 for the vehicle 1 under the same situation will be outlined. In this case, the command signal transmitted from the portable device 20 includes only the wireless ID 1. Accordingly, the electronic control device 32 of the vehicle 1 realizes unlocking of the door lock as a result of the ID collation, but the electronic control device 32 of the vehicle 2 does not match the ID code (the wireless ID 1 does not exist in the registration data). Therefore, unlocking the door lock is not realized. Note that this command signal may be transmitted with a predetermined transmission power using, for example, the vicinity of 300 MHz as in the case of the response signal described above.

  Thus, according to the present embodiment, by additionally registering the smart ID 1 related to the vehicle 1 on the vehicle 2 side, the user does not need to have two portable devices 20 for the vehicles 1 and 2. If you have the portable device 20 for the vehicle 1, you can get into either the vehicle 1 or 2. At this time, a state in which verification of the smart ID is confirmed on the vehicle side that the user does not actually intend to use is formed, but a predetermined operation (for example, operation of the door outer handle) that the user intends to unlock the door lock is formed. ) Is not realized, the door lock of the vehicle on the side not intended by the user is not unnecessarily unlocked.

  When the user commands unlocking of the door lock of the vehicle 1 by operating the switch 21 of the portable device 20, the unlocking of the door lock of the vehicle 1 is realized as usual. Unnecessary unlocking of the door lock of the vehicle 2 is not realized.

  As described above, in the vehicle remote control device according to the present embodiment, a user using a plurality of vehicles adds the smart ID related to the portable device 20 possessed by the user to the electronic control device 32 (memory) of the plurality of vehicles. By registering, the plurality of vehicles can be used with only one portable device 20.

  In the present embodiment, similarly, the smart ID 2 related to the vehicle 2 may be registered in the memory of the electronic control device 32 of the vehicle 1 in addition to the smart ID 1 related to the vehicle 1 and the wireless ID 1.

  In addition, as a matter of course, in this embodiment, the user who uses the vehicle 2 with the portable device 20 for the vehicle 1 as described above can drive the vehicle 2 instead of just getting on the vehicle 2. For example, when the immobilizer function is given to the vehicle 2, the transponder ID may be collated between the portable device 20 for the vehicle 1 and the communication device for in-vehicle communication via transponder communication. At this time, in addition to the transponder ID 1 given in advance to the vehicle 1, the transponder ID 2 related to the vehicle 2 is registered in the registration data in the memory of the electronic control device 32. Thereby, the verification of the transponder ID is confirmed, and the operation state of the immobilizer function is released. As a result, the user who has the portable device 20 for the vehicle 1 can start the engine of the vehicle 2 and drive the vehicle 2 as usual. Note that a communication device (not shown) for in-vehicle communication may be disposed on the instrument panel in front of the driver's seat.

  In the present embodiment, the user who uses the vehicle 2 with the portable device 20 for the vehicle 1 can also lock the door lock of the vehicle 2 and set the immobilizer function after the operation of the vehicle 2 is completed. . In this case, when the electronic control device 32 detects an operation of the lock switch 70 (see FIG. 3) outside the vehicle by the user, the electronic control device 32 starts the same smart communication with the portable device 20 and passes the smart communication. A lock of the door lock and / or a set of immobilizer functions is realized by collating and checking the smart ID. The lock switch 70 is, for example, a switch that is disposed on the door outer handle and detects a user's intention (trigger) to lock the door lock (see FIG. 3).

  In the above-described embodiment, an additional smart ID is registered on the vehicle side, but an additional smart ID may be registered on the portable device 20 side. In this case, the portable device 20 transmits a response signal including the smart ID additionally registered in addition to the smart ID assigned initially. If any one of the plurality of smart IDs included in the response signal matches the vehicle-side smart ID, the electronic control device 32 detects the approach of the legitimate user to the vehicle. Thereafter, similarly, the electronic control unit 32 detects the detection of the door opening operation by the user by the touch sensor with a built-in door outer handle within a predetermined time after detecting the approach of the legitimate user to the vehicle. Sometimes, the door lock is unlocked by sending a control signal to a door lock actuator that drives a door lock mechanism of a predetermined door.

  Next, with reference to FIG.2 and FIG.3, the door lock system which may be used for the above-mentioned remote control apparatus for vehicles is demonstrated. The remote control device for a vehicle according to the present embodiment realizes ID collation that requires electrical energy by using power when a user operates the door outer handle 90. Therefore, the door lock system of the present embodiment is particularly useful in an emergency state in which normal power supply from the battery is cut off.

  FIG. 2 shows a power storage unit of the power generation door lock system. As shown in FIG. 2, when the user operates the door outer handle 90, the rod 92 moves downward. This lowering operation of the rod 92 is converted into a rotation operation of the power generation rotor 94, and power generation by the power generation rotor 94 is realized. The electric power generated in the power generation rotor 94 is converted into direct current through the rectifier circuit 96 and then stored in the storage capacitor 98.

  FIG. 3 shows a configuration of a verification unit that performs ID verification using the power stored in the storage capacitor 98. Here, an emergency state in which normal power supply from the battery is cut off is assumed. In this case, since the vehicle-side transceiver 30 cannot transmit the above-described request signal and cannot receive the command signal from the portable device 20, the user who owns the portable device 20 approaches the vehicle and approaches the door outer. Even if the handle is touched or the user operates the switch 21 of the portable device 20, the unlocking of the door lock is not realized. Normally, the portable device 20 is provided with a mechanical key that is inserted into the key cylinder of the door outer handle, assuming such an emergency state, and the user uses the mechanical key of the portable device 20. The door lock is unlocked by mechanically operating the link of the door lock mechanism.

  On the other hand, in this embodiment, when the user presses the lock switch 70 while holding the portable device 20 near the door outer handle, the transceiver 30 uses the power stored in the storage capacitor 98 as a power source. Transponder communication is performed with the portable device 20 via the antenna 99 with a built-in outer handle. That is, the electronic control device 32 causes the transceiver 30 to transmit a request signal. In this transponder communication, the use band is around 134 kHz, and the radio wave used is a weak radio wave having a communication distance of about several centimeters with the transceiver 30.

  In response to the request signal from the transceiver 30, the portable device 20 transmits a response signal including the transponder ID assigned to itself. The vehicle transceiver 30 performs predetermined processing such as amplification and demodulation on the response signal received via the antenna 99 using the electric power stored in the storage capacitor 98 as the power source, and then transmits the response signal to the electronic signal. This is supplied to the control device 32.

  The electronic control device 32 collates the portable device-side transponder ID and the vehicle-side transponder ID included in the response signal using the power stored in the storage capacitor 98 as a power source. Note that the portable device-side transponder ID and the vehicle-side transponder ID are initially assigned to each vehicle in the same manner as the smart ID and the wireless ID, and the vehicle-side transponder ID is stored in the memory of the electronic control device 32. May be included in the registration data. If the ID verification is confirmed as described above as a result of the ID verification, the electronic control unit 32 uses the power stored in the storage capacitor 98 as a power source to drive a door lock mechanism for a predetermined door. The door lock actuator unlocks the door lock using the power stored in the storage capacitor 98 as a power source.

  Thus, according to the present embodiment, even in an emergency state in which the power supply from the battery to the electronic component on the vehicle side is cut off, the power stored in the storage capacitor 98 without using the mechanical key of the portable device 20. Can be used to unlock the door lock. Therefore, it is not necessary to give the function of the mechanical key to the portable device 20, and ultimately, the door side mechanical key itself can be made unnecessary. In this case, since the key cylinder and the link of the door lock mechanism for realizing the unlocking of the door lock are not required (that is, the rod 92 does not constitute the link of the door lock mechanism), the crime prevention performance of the vehicle is improved.

  In the present embodiment, in addition to the individual transponder ID given in advance for each vehicle as described above, the transponder ID related to another vehicle is additionally registered in the registration data in the memory of the electronic control device 32. In this case, the unlocking of the door lock described above can also be realized using the portable device 20 corresponding to the other vehicle. Thereby, the convenience of the user who uses multiple vehicles improves like the above-mentioned example.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  In the above-described embodiments, different ID codes are used for smart communication and transponder communication, but a common ID code may be used.
