Title:
POWER SUPPLY CONTROL DEVICE FOR ELECTRIC ACTUATORS FOR DOOR-RELATED ACCESSORIES IN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/148732
Kind Code:
A1
Abstract:
A vehicle is equipped with a distribution board which is provided between a plurality of electric actuators and an auxiliary power supply, said plurality of electric actuators being used for door-related accessories and including a door lock device electric actuator that is appended to a door lock device, and said auxiliary power supply being connected to a main power supply. The vehicle is such that when a shock detection sensor (11) detects a shock at the same time that the voltage applied to the auxiliary power supply (33) by the main power supply (12) drops to a level not higher than a predetermined voltage, a control means (29) for controlling the distribution board (30) brings the door lock device into the unlocked state while the power feed from the auxiliary power supply (33) to the door lock device electric actuator (18) is maintained, said door lock device electric actuator (18) being among door-related electric actuators (13, 14, 15, 17, 18); and that in spite of the above, the power feed from the auxiliary power supply (33) to the remaining door-related electric actuators (13, 14, 15, 17) is forcibly stopped. Due to the above, even if a power supply or a circuit thereof is destroyed due to a collision or the like, burglar-proofness is enhanced while keeping the door locked state releasable.
