Description

  The present invention relates to an engine remote operation system for starting a vehicle-mounted engine by remote operation.

  A conventional engine remote control system as shown in FIG. 4 is known (see, for example, Patent Document 1).

  First, in terms of configuration, the engine remote control system includes a portable device 41 carried by a vehicle user (driver) and an in-vehicle device 42 mounted on the vehicle.

  And the portable device 41 has the transmitter 43 provided with the transmission antenna 43a, and the vehicle equipment 42 has the controller 45 which controls the start-up and stop of the receiver 44 provided with the reception antenna 44a, and an engine. When a vehicle user presses a start button (not shown) of the portable device 41, an engine start command signal is input from the transmission device 43 to the controller 45 via the reception device 44. Yes.

  The controller 45 includes a door opening / closing detection device 46 that outputs a signal when the vehicle door is opened, a parking brake detection device 47 that outputs a signal when the parking brake is released, and a shift lever other than the parking range. A shift lever position detection device 48 that outputs a signal when in the range is connected.

  The controller 45 is connected to a starter switch 49, a shift interlock device 50, an ignition device 51, and a starter motor driving device 52.

  The shift interlock device 50 locks the shift lever after the engine is started so that the shift lever cannot be switched from the parking position or the neutral position to the traveling position.

  Further, the controller 45 includes a timer 53, and after starting the engine based on the engine start command signal input from the receiving device 44, the vehicle door is opened and a signal is input from the door open / close detection device 46. If the ignition key is not operated and no signal is input from the starter switch 49 within a predetermined time after the door is opened, the power supply to the ignition device 51 is cut off. Then, the engine is stopped.

  Further, the controller 45 outputs a signal to the shift interlock device 50 without stopping the engine when a signal is input from the starter switch 49 before a predetermined time elapses after the door is opened. The lock is released and the vehicle is set in a state where it can run.

  Next, the operation of the conventional engine remote control system will be described.

  When there is no input signal from the door opening / closing detection device 46, the parking brake detection device 47, and the shift lever position detection device 48, the controller 45 receives the engine start command signal from the reception device 44, and the ignition device 51 and the starter The motor driving device 52 is operated to start the engine.

  Then, after starting the engine, the controller 45 outputs a signal to the shift interlock device 50 to lock the shift lever so that the shift lever cannot be switched from the parking position or the neutral position to the traveling position. .

  In addition, when the door is opened after the engine is started, the controller 45 is operated when the ignition key is not operated during a predetermined time, for example, 10 seconds from the time when the door is opened (from the starter switch 49). When no signal is input), the power supply to the ignition device 51 is cut off and the engine is stopped.

  On the other hand, the controller 45 stops the engine when the ignition key is operated and a signal is input from the starter switch 49 before the predetermined time elapses after the door is opened after the engine is started. Instead, a signal is output to the shift interlock device 50 to release the lock, and the vehicle is set in a state capable of traveling.

As described above, in the conventional engine remote control system, after the engine is started by remote control, the ignition key is turned on within a predetermined time from the time when the shift lever of the shift interlock device 50 is locked and the door is opened. The vehicle is stolen by stopping the engine when there is no operation.
Japanese Utility Model Publication No. 5-21172 (paragraphs 0017 to 0057).

  However, in the conventional engine remote control system, the engine is stopped when the starter switch is not operated with the ignition key within a predetermined time after opening the door and getting into the vehicle.

  Moreover, the predetermined time needs to be set to a relatively short time (for example, 10 seconds) for the purpose of preventing theft.

  For this reason, it is necessary to operate the starter switch immediately after getting into the vehicle, which is a burden on the driver.

  Therefore, the present invention can prevent theft of the vehicle between the time when the engine is started remotely and the time when the vehicle is started, and can reduce the burden on the driver between the start of the engine and the start of the vehicle. The purpose is to provide an engine remote control system.

In order to achieve the above object, the present invention comprises an engine start signal transmission device that is carried by a vehicle user and wirelessly transmits a command signal for starting a vehicle engine;
A unique code signal transmission device that is carried by a user of the vehicle and wirelessly transmits a signal including the unique code;
A vehicle-mounted control device mounted on a vehicle, to which a signal including the command signal and the unique code is input;
The in-vehicle control device has a unique code transmitted from the unique code signal transmission device when the engine is started by the command signal and is in a driving state and the unique code signal transmission device is in a predetermined area. A unique code matching means for matching with the unique code;
When the unique code matching means confirms that the unique code matches, the vehicle is set to a startable state, and when the unique code match is not confirmed, the vehicle is set to a start impossible state. It features an engine remote control system having vehicle state setting means.

  According to the present invention configured as described above, when the engine is started by a remote operation and is in a driving state, the unique code stored in the unique code signal transmission device possessed by the user (driver) of the vehicle, The unique code stored in the control device is collated, and when the unique code matches, the vehicle is set to a startable state. When the unique code does not match, the vehicle is not started. It is set to a possible state.

  For this reason, since the operation for preventing theft of the vehicle between the time when the engine is started by remote operation and the time when the vehicle is started is automatically performed by checking the unique code, the time between the engine start and the vehicle start It is possible to reduce the burden on the driver.

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

  First, in terms of configuration, the engine remote control system according to the present embodiment, as shown in FIG. 1, is carried by the first portable device 1 carried by the vehicle user (driver) and the vehicle user.

  In the determination of step S3 to step S6 in the in-vehicle controller 5, the door is not opened and closed, the parking brake is not forgotten, the shift lever is not misplaced, and the second portable device 2 is moved into the vehicle interior. If it is confirmed that there is no misplacement, the ignition device 11 and the starter motor drive device 12 are operated and the engine is started (step S7).

  When the second portable device 2 is left in the passenger compartment, the engine is not started, so that a third person gets in and runs the vehicle before the user reaches the vehicle. Can be prevented.

  After the engine is started, in step 8, the shift interlock device 10 is operated to lock the shift lever so that the shift lever cannot be switched from the parking position or the neutral position to the traveling position.

  Subsequently, in step S <b> 9, the unique code stored in the second portable device 2 transmitted from the unique code signal transmission device 2 a and the unique code stored in the in-vehicle control device 5 are collated.

  When the coincidence of the two unique codes is confirmed, in step S10, the shift interlock device 10 is released without stopping the engine, and the starter switch 9 is operated to turn on the accessory switch. The vehicle is set in a startable state.

  On the other hand, when the unique codes do not match, in step 11, the supply of power to the ignition device 11 is cut off and the engine is stopped.

  In this way, a series of processing of the engine remote operation system of the present embodiment is completed (step S12).

  As described above, in the present embodiment, when the engine is started by a remote operation and is in a driving state, the unique code stored in the unique code signal transmission device possessed by the vehicle user (driver), the on-vehicle control The unique codes stored in the device are collated, and when the unique codes match, the vehicle is set to a startable state. When the unique codes do not match, the vehicle is not started. It is set to a possible state.

  For this reason, since confirmation for preventing vehicle theft between the time when the engine is started by remote operation and the time when the vehicle is started is automatically performed by collating the unique code, the time between engine start and vehicle start It is possible to reduce the burden on the driver.
