To effectively identify the driver's driving intention and improve the fuel economy of the hybrid vehicle,a method of adjusting the torque distribution of the engine and motor in real time according to the real-time demand power of the driver and the universal characteristics of the engine is proposed.Through the analysis of the fuel consumption of the whole vehicle,the minimum objective function of the real-time instantaneous fuel consumption rate of the whole vehicle is constructed,so as to calculate and adjust the torque distribution of the whole vehicle in real time,so that the engine and motor can maintain the highest comprehensive efficiency.The test results show that this method can reduce the fuel consumption by 5.01%per 100 kilometers.
