Title:
MOTOR UNIT
Document Type and Number:
WIPO Patent Application WO/2019/194076
Kind Code:
A1
Abstract:
One aspect of this motor unit comprises a power generator, a motor, a transmission mechanism, a clutch, a rotation sensor for a power generator, a rotation sensor for a motor, and a control unit. The transmission mechanism has an engine drive shaft rotated by an engine. The engine drive shaft has a first shaft part and a second shaft part disconnected or connected by a clutch. In a clutch-connecting operation, the control unit supplies power to the power generator and causes torque to be imparted to the first shaft part by the power generator on the basis of the difference between the rotational speed of the first shaft part calculated from the rotational speed of the power generator and the rotational speed of the second shaft part calculated from the rotational speed of the motor, and causes the rotational speed of the first shaft part to approach the rotational speed of the second shaft part.
