Abstract

A vehicle remote starting apparatus includes a control device that starts an engine when the control device has set a registration flag and the control device receives an engine starting signal from an external device, which is apart from the vehicle remote starting apparatus. When the vehicle remote starting apparatus is mounted on a vehicle, the control device executes registration process for setting the registration flag, which allows the control device to start the engine when the control device receives the engine starting signal.

Claims

1. A vehicle remote starting apparatus for use with a vehicle having an engine, comprising:

an external device that generates an engine starting signal; and

a control device that starts the engine when the control device has set a registration flag and the control device receives the engine starting signal from the external device, the external device being seperate from the control device, wherein;

when the control device is mounted on the vehicle, the control device executes an initial registration process for setting the registration flag, which allows the control device to start the engine when the control device receives the engine starting signal.

2. The vehicle remote starting apparatus according to claim 1, wherein:

the control device receives a signal input from the vehicle;

when the control device receives the engine starting signal, after the control device is mounted on the vehicle, and confirms that the signal input from the vehicle satisfies an engine starting condition, the control device starts the engine;

during the initial registration process the control device checks for changes in the signal input from the vehicle; and

when the control device determines that the signal input from the vehicle does not change during the registration process, the control device does not set the registration flag.

3. The vehicle remote starting apparatus according to claim 2, wherein during the registration process, the control device requests a user to operate the vehicle in a predetermined way, and then checks as to whether or not the signal input from the vehicle changes in response to user'"'"'s operation.

4. The vehicle remote starting apparatus according to claim 2, wherein the signal input from the vehicle changes in response to a state of a switch, which is turned off when the switch is in a normal state and is turned on when the switch is operated.

5. The vehicle remote starting apparatus according to claim 2, wherein the signal input from the vehicle is a signal output from a group consisting of a door switch, a hood switch, a key sensor, an ignition switch, a brake switch, a shift position, and a gear shift position sensor.

6. The vehicle remote starting apparatus according to claim 2, further comprising:

a display device disposed on the control device, wherein;

when the control device has not set the registration flag, the control device displays on the display device a message indicating that the control device is in an inhibition state.

7. The vehicle remote starting apparatus according to claim 1, wherein when the control device of the vehicle remote starting apparatus is powered down, the control device releases the registration flag which has been set in the initial registration process.

8. The vehicle remote starting apparatus according to claim 7, wherein when the control device of the vehicle remote starting apparatus is powered down in a state where a hood of the vehicle is opened, the control device does not release the registration flag which has been set in the initial registration process.

9. The vehicle remote starting apparatus according to claim 1, wherein when the control device of the vehicle remote starting apparatus is powered on, the control device releases the registration flag which has been set in the initial registration process except for in a state where a hood of the vehicle is opened.

10. The vehicle remote starting apparatus according to claim 1, wherein when the engine is started using a key, the control device checks the signal input from the vehicle and then if the signal input from the vehicle does not satisfy a predetermined condition, the control device releases the registration flag which has been set in the initial registration process.

11. The vehicle remote starting apparatus according to claim 1, wherein:

the signal input from the vehicle includes a specific signal, which should be in a predetermined state during traveling of the vehicle; and

during the traveling of the vehicle, the control device checks the specific signal and then if the specific signal is not in the predetermined state, the control device releases the registration flag which has been set in the initial registration process.

12. The vehicle remote starting apparatus according to claim 1, wherein the external device is a portable remote controller that is capable of transmitting the engine starting signal to the vehicle remote starting apparatus.

13. A vehicle remote starting system comprising:

a signal transmission unit that transmits an engine starting signal; and

a control device that starts an engine when the control device has set a registration flag and the control device receives the engine starting signal from the signal transmission unit, the control device being separate from the signal transmission unit wherein;

when the control device is mounted on a vehicle, the control device executes an initial registration process for setting the registration flag, which allows the control device to start the engine when the control device receives the engine starting signal.

14. A method for executing a registration process for initially setting a registration flag, which allows a control device to start an engine when the control device receives an engine starting signal from an external device, the method comprising:

checking changing of a signal input from a vehicle; and

when the signal input from the vehicle changes, setting the registration flag.

15. The method according to claim 14, wherein the checking comprises requesting a user to operate the vehicle in a predetermined way, and then checking as to whether or not the signal input from the vehicle changes in response to user'"'"'s operation.

16. A control device which is configured to start an engine of a vehicle when a registration flag is set and an engine starting signal is received from an external device which is separated from the control device,

wherein when the control device is mounted on the vehicle, the control device executes an initial registration process for setting the registration flag, which allows the control device to start the engine when the engine starting signal is received.
