Title:
CONTROL DEVICE AND DRIVE MECHANISM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/246371
Kind Code:
A1
Abstract:
The present invention addresses the problem of preventing elements such as, for example, a coil of a motor and an inverter from being degraded and damaged due to heat generation and obtaining a high vehicle driving performance. This control device controls a drive mechanism including a motor and is provided with: an upper limit torque value line update unit for updating, on the basis of the state of the drive mechanism, an upper limit torque value line indicating an upper limit torque value; and a drive control unit for determining, on the basis of the estimated temperature of an element after a delay time has elapsed from the present, whether it is necessary to limit a torque value or not and controlling the torque value on the basis of the upper limit torque value line when it is necessary to limit the torque value.
