Method of operating an in-vehicle charger, and an in-vehicle charger mounted to a vehicle
View Patent ↗A method for operating an in-vehicle charger and an in-vehicle charger mounted to a vehicle. The in-vehicle charger includes a charging coil for performing non-contact charging to a mobile device placed in the vehicle; and a control unit connected to the charging coil. The control unit instructs start or stop of supplying power to the charging coil in response to detecting a first signal indicating the engine is driven and a second signal indicating a state of a vehicle component of the vehicle other than the engine. The method includes a step of detecting the first signal; a step of detecting the second signal; and a step of instructing a start or stop of supplying power to the charging coil in response to detecting both of the first and second signals.
1. A method for operating an in-vehicle charger, the in-vehicle charger including a charging coil for performing non-contact charging to a mobile device placed in a vehicle to which the in-vehicle charger is mounted, comprising:
a step of detecting, in the in-vehicle charger, a first signal indicating the engine is driven;
a step of detecting, in the in-vehicle charger, a second signal indicating a state of a vehicle component of the vehicle other than the engine; and
a step of instructing a start or stop of supplying power to the charging coil in response to detecting both of the first signal and the second signal,
wherein the second signal is at least one of a brake release signal of the vehicle and a speed pulse signal from a speed pulse detection unit.
2. The method according to claim 1 , wherein the start of supplying power to the charging coil is instructed in response to detecting both that the engine is driven and the brake is released.
3. The method according to claim 1 , wherein the start of supplying power to the charging coil is instructed in response to detecting both that the engine is driven and the vehicle is moving.
4. The method according to claim 1 , wherein the start of supplying power to the charging coil is instructed in response to detecting that the engine is driven, the brake is released, and the vehicle is moving.
5. The method according to claim 1 , wherein the stop of supplying power to the charging coil is instructed in response to detecting both that the engine is driven and the brake is not released.
6. The method according to claim 1 , wherein in the step of instructing the start or stop of supplying of power to the charging coil, determining whether or not the vehicle is in a state where communication between a communication device in the vehicle and a wireless key may possibly be performed based on the first signal and the second signal.
7. An in-vehicle charger mounted to a vehicle comprising:
a charging coil for performing non-contact charging to a mobile device placed in the vehicle; and
a control unit connected to a charging coil,
wherein the control unit instructs a start or stop of supplying power to the charging coil in response to detecting a first signal indicating the engine is driven and a second signal indicating a state of a vehicle component of the vehicle other than the engine, and
wherein the second signal is at least one of a brake release signal of the vehicle and a speed pulse signal from a speed pulse detection unit.
8. The in-vehicle charger according to claim 7 , wherein the control unit instructs the start of supplying power to the charging coil in response to detecting both that the engine is driven and the brake is released.
9. The in-vehicle charger according to claim 7 , wherein the control unit instructs the start of supplying power to the charging coil in response to detecting both that the engine is driven and the vehicle is moving.
10. The in-vehicle charger according to claim 7 , wherein the control unit instructs the start of supplying power to the charging coil in response to detecting that the engine is driven, the brake is released, and the vehicle is moving.
11. The in-vehicle charger according to claim 7 , wherein the control unit instructs the stop of supplying power to the charging coil in response to detecting both that the engine is driven and the brake is not released.
12. The in-vehicle charger according to claim 7 , wherein the control unit determines whether or not the vehicle is in a state where communication between a communication device in the vehicle and a wireless key may possibly be performed based on the first signal and the second signal, and instructs the start or stop of supplying power to the charging coil in response to the determination.
