Vehicle and control method thereof
A vehicle may include an auxiliary battery to prevent full discharge of a main power source while remotely controlling electronic devices of the vehicle, wherein the vehicle may include a communication device configured to receive a control signal indicating a control command from a mobile device; a controller configured to control a target of control based on the control signal; and a power management device including an auxiliary battery and configured to supply power to the controller using the auxiliary battery when the communication device receives the control signal while an ignition of the vehicle is turned off.
1. A vehicle comprising:
a communication device configured to receive a control signal indicating a control command from a mobile device;
a controller configured to control a target of control based on the control signal;
a memory configured to perform a backup of data of the controller; and
a power management device including an auxiliary battery and configured to supply power to the controller using the auxiliary battery when the communication device receives the control signal while an ignition of the vehicle is turned off,
wherein when functions of the controller are deactivated and data stored in the controller is lost, the power management device boots the controller by supplying power to the controller using the auxiliary battery and uploads the lost data based on the data stored in the memory to the controller.
2. The vehicle according to claim 1 , wherein the controller receives power from a main power source of the vehicle when the ignition of the vehicle is turned on.
3. The vehicle according to claim 1 , wherein the power management device blocks a supply of power from the auxiliary battery when the ignition of the vehicle is turned on.
4. The vehicle according to claim 1 , wherein the power management device switches the auxiliary battery into a charging state when the ignition of the vehicle is turned on.
5. The vehicle according to claim 1 ,
wherein the power management device is configured to download data related to control of the vehicle from the controller and to store the data in the memory while the ignition of the vehicle is turned on.
6. The vehicle according to claim 1 , wherein when the controller is deactivated, the power management device is configured to boot the controller by supplying power to the controller using the auxiliary battery.
7. The vehicle according to claim 1 , wherein when the communication device receives the control signal while the ignition of the vehicle is turned off, the power management device is configured to boot the controller by supplying power to the controller using the auxiliary battery.
8. The vehicle according to claim 1 , wherein the power management device supplies power to the controller using the auxiliary battery until the controller completes predetermined operation and blocks the supply of power to the controller upon completion of the operation while the ignition of the vehicle is turned off.
9. A method of controlling a vehicle, the method comprising:
determining whether or not a control signal is received from a mobile device when an ignition of the vehicle is turned off; and
supplying power from an auxiliary battery to a controller of the vehicle by a power management device of the vehicle,
wherein the method further includes:
booting the controller by supplying power to the controller using the auxiliary battery by the power management device and uploading the lost data based on the data stored in the memory to the controller by the power management device, when functions of the controller are deactivated and data stored in the controller is lost.
10. The method according to claim 9 , further comprising supplying power from a main power source to the controller when the ignition of the vehicle is turned on.
11. The method according to claim 9 , further comprising blocking a supply of power from the auxiliary battery by the power management device when the ignition of the vehicle is turned on.
12. The method according to claim 9 , further comprising switching the auxiliary battery to a charging state when the ignition of the vehicle is turned on.
13. The method according to claim 9 , further comprising downloading data related to control of the vehicle from the controller by the power management device of the vehicle and storing the data in the memory when the ignition of the vehicle is turned on.
14. The method according to claim 9 , further comprising booting the controller by supplying power to the controller using the auxiliary battery by the power management device when the controller are deactivated.
15. The method according to claim 9 , wherein the supplying of power to the controller of the vehicle comprises booting the controller by supplying power to the controller using the auxiliary battery by the power management device of the vehicle upon receiving the control signal from the mobile device.
16. The method according to claim 9 , further comprising:
supplying power to the controller using the auxiliary battery until the controller completes predetermined operation by the power management device; and
blocking the supply of power to the controller upon completion of the operation by the power management device, while the ignition of the vehicle is turned off.
