Abstract
There is provided a motor lock prevention control device for a hybrid vehicle that has a motor-generator and a clutch capable of changing a transmission torque capacity between the motor-generator and driving wheels. The motor lock prevention control device is configured to, when the motor-generator 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 by adjusting at least one of the transmission torque capacity of the clutch and torque of the motor-generator in such a manner that the torque of the motor-generator exceeds the transmission torque capacity of the clutch.
