In this case, the engine can be started without getting into the vehicle, so if you set the air conditioner in advance in the summer or winter season, just before turning off the engine, There are advantages such as making the temperature comfortable.

  Since the ignition switch 24 is provided with an accessory switch 25 that is turned on / off in conjunction with the ignition switch 24 being turned on / off, the accessory switch 25 is turned on when the ignition switch 24 is turned on. Thus, as the navigation device 14 is activated and the ignition switch 24 is turned off to stop the engine, the accessory switch 25 is turned off and the navigation device 14 is also stopped.

  In this case, in the navigation device 14 in which the acoustic device 21 such as a radio or a CD player is integrated, the navigation device 14 and the acoustic device 21 are interlocked, and the acoustic device 21 is activated as the navigation device 14 is activated. When the navigation device 14 is stopped and the navigation device 14 is stopped, the audio equipment 21 is also stopped.

  However, when the driver forgets to turn on the mute switch before turning off and the ignition switch 24 is turned off and the engine is stopped, the next time the remote control starter 26 is turned on, the navigation device When 14 is activated, the audio equipment 21 is also activated, and noise is generated around the vehicle.

  Therefore, in the present embodiment, the navigation device 14 is selectively activated when the engine of the vehicle is started by remotely operating the remote control starter 26.

  FIG. 2 is a flowchart showing the operation of the navigation activation control system in the embodiment of the present invention.

  In this case, the battery 20 and the power supply control unit 23 are electrically connected with the ignition switch 24 and the accessory switch 25 turned off, and the navigation device 14 is placed in the state 1. In the state 1, a minute current supply processing unit (not shown) of the power supply control unit 23 performs a minute current supply process and supplies a minute current that does not erase the contents recorded in the RAM 32, ROM 33, data recording unit 16, and the like. To do.

  By the way, in the present embodiment, when the remote control starter 26 is turned on, the first activation mode for activating the navigation device 14 and the second activation mode for not activating the navigation device 14 are selectively set. Can be done. Therefore, when the driver operates the display unit 35 to select the first and second activation modes, the activation mode setting processing unit (not shown) of the power supply control unit 23 performs the activation mode setting process. The second activation mode is selectively set.

  Therefore, when the driver turns on the remote control starter 26 and starts the engine of the vehicle by remote control, the start setting determination processing means (not shown) of the power supply control unit 23 performs the start setting determination processing, and performs the first and second settings. It is determined which one of the startup setting modes is set.

  When the second activation setting mode is set, the navigation device 14 is placed in the state 2. In the state 2, the activation processing unit does not activate the navigation device 14. Then, the screen of the display unit 35 becomes a black screen or an audio off screen on which nothing is displayed, the sound output unit 37 does not output sound, and the acoustic device 21 is not activated.

  Then, an operation determination processing unit (not shown) of the power supply control unit 23 performs an operation determination process, and in this embodiment, whether or not the driver has boarded and performed a predetermined operation to activate the navigation device 14. , If the driver has inserted the start key into the key groove and rotated it to the first position, and if the driver has inserted the start key into the key groove and rotated it to the first position, An activation processing unit (not shown) of the power supply control unit 23 performs activation processing, applies a control voltage of 5 [V] to the navigation device 14, and activates the navigation device 14. In this case, an activation operation unit is configured by the start key.

  Note that when the driver inserts the start key into the keyway and rotates it to the first position, the startup process is performed. However, the driver turns on a power switch (not shown) of the operation unit 34. When activated, the activation process can be performed. In this case, a startup operation unit is configured by the power switch.

  On the other hand, when the first activation setting mode is set, the activation processing means applies a control voltage of 5 [V] to the navigation device 14 and puts the navigation device 14 in the state 3. That is, the navigation device 14 is activated, the screen of the display unit 35 becomes an initial screen, a predetermined initial audio is output by the audio output unit 37, and the acoustic device 21 is also activated.

  Subsequently, the activation mode setting processing means determines whether or not the change of the activation mode is instructed by the driver operating the operation unit 34, and when the change is instructed, the activation mode is changed. If not instructed, keep current boot mode.

  In this way, it is determined whether or not the first activation mode for activating the navigation device 14 is set in accordance with the operation of the remote control starter 26, and when the first activation mode is not set, the remote control starter 26 operates. The navigation device 14 is not activated. Therefore, next, when the remote control starter 26 is operated and the engine of the vehicle is started by remote control of the engine, the acoustic device 21 is not activated, so that generation of noise around the vehicle can be prevented. .

Next, a flowchart will be described.
Step S1 The engine is started by the remote control starter 26.
Step S2: Determine whether or not the first activation mode is set. When the first activation mode is set, the process proceeds to step S4, and when it is not set, the process proceeds to step S3.
Step S3: The navigation device 14 is not activated.
Step S4: The navigation device 14 is activated.
Step S5: It is determined whether or not a change of the start mode has been instructed. If the start mode change is instructed, the process proceeds to step S7. If not instructed, the process proceeds to step S6.
Step S6: The current activation mode is maintained and the process is terminated.
Step S7: The start mode is changed and the process is terminated.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.
