Abstract:
1. A motor torque management method, comprising: determining, by a Hybrid Control Unit, HCU, torque requests of a system according to a vehicle state and a driver requirement; performing synthesis and limitation on requested torques so that each of the torque requests is within a proper range; arbitrating the torques according to set priorities; and sending a torque request having the highest priority to a motor control module after smoothing of the torque request, so as to obtain a required torque; wherein: the torque requests comprise an electric mode torque request and an electricity generating mode torque request; and the management method comprises: electric mode torque synthesis and limitation, electricity generating mode torque synthesis and limitation, and torque arbitration management; wherein: the electric mode torque request comprises an auxiliary driving torque request and a battery warming-up torque request, and the auxiliary driving torque request comprises a performance electric torque request aiming for fulfilling vehicle power performance and an efficiency electric torque request aiming for improving vehicle efficiency; and the electric mode torque synthesis and limitation comprise synthesis and limitation of a performance electric torque, by which a performance electric torque limit is obtained, and comprise synthesis limitation of an efficiency electric torque, by which an efficiency electric torque limit is obtained.
