摘要：For the electro-hydraulic composite braking system, the regenerative braking is characterized by quick response, while the response of hydraulic braking is hysteretic. As the braking mode is switched, it always has a mutation of the braking torque and causes the driver to produce inconsistent braking sense. This paper mainly discusses the braking sense consistency strategy from two aspects of multi-objective optimization and compensation control. An optimized allocation method of braking force is explored under multi objectives and multi constraint conditions, which is to find the optimal distribution ratios of front and rear axles, as well as regenerative braking and hydraulic braking. Based on this, the braking sense consistency controller is further designed to make up the difference of braking force and keep the braking force change rate unchanged. Simulation results show that the composite braking system with the proposed strategy can not only eliminate the fluctuation in braking mode switching and ensure the driver obtaining consistent braking sense, but also has satisfactory tracking performance and strong anti-interference ability.
