摘要/Abstract

摘要：

为在保证人车安全性的基础上给驾驶员带来更好的制动体验，根据制动主缸压力及压力变化率采用模糊推理对驾驶员制动意图进行识别，将制动意图分为常规减速和紧急制动，分别设计助力电流控制和主动压力控制两种策略，并进行实车验证。结果表明：压力主动控制模式下，制动主缸压力能迅速跟随目标压力；助力电流控制模式下，助力电流能较好地跟随目标电流；对比普通控制策略和本文控制策略在迅速踩下制动踏板时的压力曲线，后者能更快地完成制动主缸建压过程。

Abstract:

In order to give the driver better braking experience on the basis of ensuring safety， the driver’s braking intention is identified according to the pressure of the brake master cylinder and the rate of pressure change. First， the braking intention is divided into conventional deceleration and emergency braking. Then， two control strategies， current closed-loop control and active pressure control， are designed respectively. The two control strategies were verified by real car experiments. The experimental results show that： under active pressure control mode， the brake master cylinder pressure can quickly follow the target pressure. In the current closed-loop control mode， the booster current can follow the target current well. Compared with the ordinary control strategy， the control strategies designed in this paper can complete the process of building the brake master cylinder faster.
