Abstract
An HV-ECU calculates requested output torque Tec based on requested power and compares the requested output torque with controlled upper limit torque Teth. When requested output torque Tec has attained to controlled upper limit torque Teth, the HV-ECU restricts output torque of engine to controlled upper limit torque Teth and calculates actual output torque Ter at that time. Then, the HV-ECU calculates a difference (differential torque ΔTe) between controlled upper limit torque Teth and actual output torque Ter. The HV-ECU learns controlled upper limit torque Teth based on differential torque ΔTe.
