摘　　要：为了提高混联式混合动力卡车的燃油经济性,充分发挥混合动力系统发动机与电机转速、转矩协调优化的特点,基于INCAFLOW实现了台架系统效率试验自动标定,再使用MATLAB进行离线仿真,优化混合动力模式相关标定数据,并进行转毂试验验证。结果表明,该方法在整车起停控制策略不变的情况下,有效提高了整车燃油经济性。In order to improve fuel economy for series-parallel hybrid trucks and make full use of the characteristics of coordinated optimization of the engine,motor speed and torque of the hybrid system,this paper proposes an automatic calibration method for system efficiency bench testing based on INCAFLOW,using MATLAB to do offline simulation for optimization of the calibration data of hybrid mode,then verifies on the bench.The results reveal that this method improves the vehicle’s fuel economy effectively without changing the start-stop control strategy of the vehicle.
