Motor lock prevention control for hybrid vehicle

摘要

There is provided a motor lock prevention control device for a hybrid vehicle that has a motor-generator (5) and a clutch (7) capable of changing a transmission torque capacity between the motor-generator (5) and driving wheels (2). The motor lock prevention control device is configured to, when the motor-generator (5) is in a motor locked state to cause heat generation under drive load operating condition, perform motor prevention control to induce rotation of the motor-generator (5) by adjusting at least one of the transmission torque capacity of the clutch (7) and torque of the motor-generator (5) in such a manner that the torque of the motor-generator (5) exceeds the transmission torque capacity of the clutch (7).
