摘要
When a sub transmission mechanism is switched to the LO-side gear stage, a hybrid control unit executes a control operation such that vehicle speed does not exceed limit vehicle speed determined in advance in accordance with the transmission gear ratio of LO-side gear stage. Specifically, the hybrid control unit reduces at least one of the driving torque generated by the engine and the second motor generator, so that rotation speed of the second motor generator does not exceed tolerable rotation speed. Further, the hybrid control unit reduces at least one of the driving torque generated by the engine and the second motor generator when any of temperatures respectively detected by temperature sensors exceed corresponding upper limit temperatures.
