Coordinated Control of Hybrid Electric Vehicle Based on Stochastic Network Delay Compensation

In order to improve the mode switching quality of the power-split hybrid vehicle, a torque coordinated control strategy based on stochastic network delay compensation was proposed. On the basis of the general motor torque compensation control strategy, the influence law of different communication network time delay on the stability of motor compensation control was studied to improve the accuracy of vehicle distributed coordinated control system. The composite coordinated control strategy including the BP-Smith adaptive compensation module and motor torque change rate limiting module was then proposed and verified by simulation. The results show that the control strategy can improve the system stability and smoothness of mode switching under the interference of stochastic network delay.
