摘要： A control device includes a motor control unit that controls an electric motor, a shift control unit that controls a shift by wire system of a movable body, and a torque detection unit that detects torque applied to a power transmission mechanism. The shift control unit drives an actuator unit so that the power transmission mechanism locked by a lock mechanism is unlocked, based on a change of a shift range of the shift by wire system from a parking range to a non-parking range. The motor control unit controls output of the electric motor depending on detected torque of the torque detection unit, based on the change of the shift range of the shift by wire system from the parking range to the non-parking range.

摘要： A control system for a work vehicle includes a power source including an engine and at least one electric motor configured to generate power; a transmission including a plurality of clutches coupled together and configured for selective engagement to transfer the power from the engine and the at least one electric motor along a power flow path to drive an output shaft of a powertrain according to a plurality of transmission modes; and a controller coupled to the power source and the transmission. The controller has a processor and memory architecture configured to: monitor an electric motor speed of the at least one electric motor; and generate and execute, when the electric motor speed is less than a first predetermined stall speed threshold, a clutch modulation command for the transmission such that at least one clutch of the plurality of clutches along the power flow path is partially engaged.
