Abstract
A vehicle and a method are configured to prevent malfunction of a touch sensor in a vehicle door. The vehicle includes a transceiver for transmitting a searching signal to a smart key located outside the vehicle and receiving a response signal to the searching signal, at least one touch sensor mounted in a door of the vehicle to sense a touch input of a user in a capacitive scheme, and a controller that determines an approach direction of the smart key based on the response signal and controls to operate only a touch sensor installed in a door mapped to the approach direction among the at least one touch sensor.
Claims18
A vehicle, comprising:
- a transceiver for transmitting a searching signal to a smart key located outside the vehicle and receiving a response signal from the smart key;
- at least one touch sensor mounted in a door of the vehicle to sense a touch input of a user in a capacitive scheme;
- and
- a controller configured to:
- determine an approach direction of the smart key based on the response signal;
- control to operate only a touch sensor installed in the door mapped to the approach direction among the at least one touch sensor;
- and
- store a failure code in a memory when the at least one touch sensor fails to activate a sleep mode for a predetermined number of times or more.
A method for preventing a malfunction of at least one touch sensor mounted in a door of a vehicle, the at least one touch sensor configured to sense a touch input of a user in a capacitive scheme, the method comprising:
- determining, by a controller, an approach direction of a smart key based on a response signal from the smart key to a searching signal transmitted by a transceiver of the vehicle to search for the smart key located outside the vehicle;
- controlling, by the controller, to operate only a touch sensor installed in a door mapped to the approach direction among the at least one touch sensor;
- and
- storing, by the controller, a failure code in a memory when the at least one touch sensor fails to activate a sleep mode for a predetermined number of times or more.
