摘要
针对电动汽车电—液并联ABS制动系统建立整车制动仿真模型,在干沥青路面模拟紧急制动和中等强度制动工况,与常规机械液压制动系统相比较,研究两种制动系统间的差异。试验结果表明:与常规液压制动系统相比,电动汽车电—液复合制动系统具有可回收制动能量、制动响应迅速、制动距离较短的优点,但是在制动方式切换阶段制动扭矩波动较大,导致车体制动减速度波动显著,使制动平顺性和制动感觉一致性变差。
Aiming at the electric vehicle electric hydraulic braking system ABS parallel braking simulation model is built in the simulation of emergency braking and moderate braking dry asphalt pavement, compared with the conventional mechanical hydraulic braking system, the difference between two kinds of brake system research. The test results show that compared with the conventional hydraulic braking system, electric vehicles-hydraulic braking system with Recyclable braking energy, braking response, shorter braking distance advantages, but in the braking mode switching stage brake torque fluctuations, resulting in the vehicle braking deceleration volatility significantly the braking comfort and braking feel consistency poor.
