Title: PASSENGER VEHICLE DOOR LOCK CONTROL DEVICE
Abstract:
A door lock control device for a passenger vehicle having an ignition switch comprises: a door lock relay having two input terminals (A, B), a locking output terminal (C) and an unlocking output terminal (D); a main control unit (MCU) configured to provide an MCU-state signal indicating whether the MCU has failed and to input a logic control instruction to the two input terminals (A, B) of the door lock relay to control electrical levels at the locking and unlocking output terminals of the door lock relay; a forced unlocking module connected to the two input terminals (A, B) of the door lock relay and configured to receive an ON-state signal or an OFF-state signal of the ignition switch; and a system-basis chip (SCB) configured to receive the MCU-state signal and generate an unlocking enablement signal for the forced unlocking module upon failure of the MCU, wherein, when the forced unlocking module simultaneously receives the unlocking enablement signal and the OFF-state signal of the ignition switch, the door lock relay is forced to be unlocked.
