[Abstract]:Four wheel independent drive hub motor electric vehicle four-wheel torque independently controllable. It has a unique advantage in active safety and energy saving control. This paper relies on the project of National Natural Science Foundation Youth Foundation No. 51305190). The ABS control strategy of four-wheel independent drive hub motor electric vehicle is carried out with the technology development project of enterprise four-wheel independent electric drive model car. The research on the coordination control strategy of ABS and regenerative braking. Through the rational distribution of regenerative braking torque of four wheels. Under the premise of ensuring braking efficiency and braking stability, the braking energy can be fully recovered. The research contents of this paper mainly include the following aspects: 1). Modeling of electric vehicle with four-wheel independent drive hub motor. The suspension system model is built with Matlab/Simulink software. Tire model, driver model, motor model and battery model. The model of electric vehicle with four-wheel independent drive wheel motor is built by combined simulation with vehicle dynamics simulation software CarSim. The study of ABS control strategy. Two kinds of ABS control strategies are designed: ABS fuzzy control strategy with wheel slip ratio and slip rate change as the control target; The ABS logic threshold control strategy, which takes wheel slip ratio and wheel angle acceleration / deceleration as the control target, selects high adhesion pavement, low adhesion road surface, open pavement and docking pavement. The designed ABS logic threshold control strategy is simulated by high speed emergency braking. To verify the effectiveness of the model, the regenerative braking control strategy is studied. The regenerative braking control strategy of four-wheel independent drive wheel motor electric vehicle with braking intensity as the control target is designed. According to the medium and small braking strength conditions, several typical cycle conditions and three different braking intensity conditions are selected to simulate the regenerative braking control strategy. Verify the effectiveness of the model. 4ABS and regenerative braking coordinated control strategy research. Based on the ABS control strategy and regenerative braking control strategy research. ABS and regenerative braking control strategy are designed to control the brake pedal opening and speed. According to the condition of large braking strength, high adhesion road, low adhesion road, open pavement and docking pavement are selected. The design of coordinated control strategy of ABS and regenerative braking is simulated by high-speed emergency braking to verify the validity of the model. 5) the hardware of driving simulator is tested in loop. Based on the above research. Select the small braking strength condition, carry on the hardware in loop test to the regenerative braking control strategy designed; Select high adhesion road surface, low adhesion road surface and open road surface, and carry out hardware in loop test on the coordinated control strategy of ABS and regenerative braking. The experimental results show that the designed ABS control strategy has good braking efficiency and braking stability under high speed and dangerous conditions. The regenerative braking control strategy can fully recover the braking energy under the medium and small braking strength. The coordinated control strategy of ABS and regenerative braking can not only guarantee the braking stability of vehicle under the condition of high speed emergency braking, but also fully recover the braking energy and realize the regeneration and utilization of the energy.
