Title:
回転電機制御装置
Document Type and Number:
Japanese Patent JP6504030
Kind Code:
B2
Abstract:
A motor-generator control part controls driving of a motor-generator, which is a drive power source of a vehicle. A torque limitation part of the MG control part limits a torque of the motor-generator when an element temperature indicating a system temperature increases to be higher than a limitation starting temperature. The torque limitation part continues the torque limitation, which was performed when the element temperature was at a peak temperature, until a limitation continuation period elapses, when the element temperature changes from increasing to decreasing as a result of limiting the torque of the motor-generator. Thus torque variation is suppressed while also suppressing overheating of a motor-generator driving system.
