摘要
分析电动车辆在对开路面上紧急制动时的整车受力情况,在前后轴制动力比例分配情况下,对比分析左右轮制动力分别采用低选控制、独立控制和修正独立控制3种不同制动控制策略时的制动稳定性、制动距离和制动能量回收效率。仿真结果表明,采用修正独立控制策略的电动车辆在对开路面上紧急制动时能降低横摆力矩、横摆角加速度和制动距离,且具有较高的制动能量回收效率。
The stress of the whole vehicle is analyzed when the electric vehicle is stopped with emergency on the bisectional road. Under the proportion distribution of the braking force of front and stability, distance and energy recovery efficiency of the braking analyzed when the three different control strategies such as the force of left and right back axles, the braking wheels are comparatively low selection control, independent control and modified independent control are applied. The simulation result shows that the yaw moment, yaw angular acceleration and braking distance can be reduced and the higher braking energy recovery efficiency is obtained when the electric vehicle is stopped with emergency by using the modified independent control strategy on the bisectional road.
