Title:
VEHICULAR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/034427
Kind Code:
A1
Abstract:
This parking lock mechanism comprises: a locking member that is capable of moving between a locked position, at which the locking member engages with a target rotating member that rotates in conjunction with vehicle wheels to restrict the rotation of the target rotating member, and an unlocked position, at which the locking member is separated from the target rotating member to allow the target rotating member to rotate; a drive device that drives the locking member; and a position detection device that detects the position of the locking member. When the drive device generates driving force for moving the locking member from the locked position to the unlocked position, if movement of the locking member is not detected by the position detection device, a control device executes an unlock assist process in which the absolute value of the torque of a rotary electrical machine is gradually increased so as to weaken the engaging force between the locking member and the target rotating member until movement of the locking member is detected.
