Title:
VEHICLE DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070765
Kind Code:
A1
Abstract:
In the present invention, a backlash in the rotational direction is present between a lock member in a lock position and a first rotating member. By setting, as a detected rotational position, the rotational position of a target rotating member which is detected by a rotational position sensor in the lock state of a parking lock mechanism and setting, as a theoretical lock position, the rotational position of the target rotating member in which the backlash is assumed not to be present in the lock state of the parking lock mechanism, a control device performs torque direction determination processing for determining a wheel torque direction (Ct) on the basis of the displacement direction of the detected rotational position with respect to the theoretical lock position due to the backlash.
