Abstract
A door lock release device includes an actuator for releasing a door lock, a first detection means for detecting an operation of a door handle, a first control circuit for controlling an actuation of the actuator based on the detected door handle operation, a second detection means for detecting a vehicle state, and a second control circuit independent from the first control circuit for controlling the actuation of the actuator based on the detected vehicle state.
Claims9
A door lock release device comprising:
- an actuator for releasing a door lock;
- a first detection means for detecting an operation of a door handle;
- a first control circuit for controlling an actuation of the actuator based on the detected door handle operation;
- a second detection means for detecting a vehicle state;
- and
