针对纯电动汽车电液复合制动系统电机再生制动力与液压制动力动态响应特性的差异及其非线性特性问题,提出了一种基于Agent的电液复合制动防抱死控制方法。构建了由电机Agent、液压制动Agent和ABS Agent组成的复合制动系统,依据让步策略、竞争策略和协同策略对电机再生制动力和液压制动力协调分配。MATLAB/Simulink仿真结果表明:紧急制动状态下,各Agent间能有效协作,前轮始终先于后轮进入抱死趋势,复合制动系统可以准确识别路面附着系数变化并及时调整电机制动力与液压制动力,提高了制动稳定性与系统的自适应能力。
For the dynamic response characteristics differences between the motor regenerative braking forces and the hydraulic braking forces and the nonlinear characteristics of the electro-hydrau- lic braking systems of a battery electric vehicle, an anti-lock braking method was proposed based on Agents for electro-hydraulic braking systems. The motor regenerative braking forces and hydraulic braking forces were distributed according to unilateral concession strategy, competition strategy and cooperative strategy of the Agent based braking systems which was composed of motor Agent, hy- draulic braking Agent and ABS Agent. MATLAB/Simulink simulation results show that the front wheel is always ahead of the rear wheel into the lock trends by cooperation among Agents under emer- gency braking conditions, besides, the Agent based braking system may identify road adhesion accu- rately to distribute the motor regenerative braking forces and the hydraulic braking forces, braking stability and adaptive ability of the braking systems are promoted.
