Motor torque limit hybrid system method

The present invention relates to a multi-motor hybrid system motor torque limiting method, which comprises the following steps: Step A, the vehicle is determined in hybrid mode and determines the priority assigned to the motor torque limit; procedure B, to be selected according to the priority allocation limit and determine the motor power limit; step C, and according to the power limit, efficiency of real-time speed and real-time determination of the first value of the motor torque; procedure D, the second motor torque limit value is determined according to the real-time transfer Issue; step E, by itself, the motor controller which is calculated in real time to obtain a third torque limit; and a step F, and Comparative three torque limit torque of the motor is defined in accordance with the smallest. Multi-motor torque limit of the proposed method of the present invention is comprehensively considered reasonable distribution among multi-motor torque limit, reasonable and effective use of the characteristics of the motors, with strong practicability.
