Abstract

To CVT-based hybrid electric vehicle, this paper proposed a new algorithm for the motor torque. The algorithm can realize smoothness of mode switching from pure electric mode to the engine operating mode. In the CVT speed ratio computing function, this algorithm obtain engine pseudo-target speed according to speed and throttle opening. According to the engine output characteristics and throttle opening and engine pseudo speed, we can get engine pseudo torque and derive motor output torque. Simulation results show that this algorithm can realize smoothness of mode switching.
