Door lock controller and the method thereof

摘要

When a request switch is actuated in a state where a signal outputted from a transmitter cannot be received, a cipher is inputted in accordance with the number of times the request switch is actuated. An answer back operation in response to the actuation of the request switch is performed by illuminating a lamp provided in a passenger compartment. An inputted cipher is checked by referring ciphers stored in a storage section in advance. When a coincidence exists, the control section outputs a control signal to a door lock motor drive section, thereby actuating a door lock motor to unlock a door lock.
