摘　　要：汽车制动踏板感觉已成为当前整车厂商越来越关注的汽车品质之一。电子液压制动器因其响应快、安全性高、可线控制动等优点,将逐步取代传统的真空助力器。文章提出一种适合解耦式电子液压制动系统的踏板感觉设计与评价方法,以提高系统开发效率,提升制动踏板感觉。应用实例及车辆试验表明,踏板感觉理论设计能够吻合正常测试,评价方法能够对应主观感受并指导踏板感觉设计。Brake pedal feeling has become an important quality that automobile manufacturers pay more and more attention to.The electro-hydraulic brake will gradually replace the traditional vacuum booster with the advantage of fast response,high safety and brake-by-wire.In order to improve the efficiency of brake system development and the brake pedal feeling,a design and evaluation method of pedal feeling for the decoupled electro-hydraulic brake system is present in this paper.Application examples and vehicle tests show that the theoretical design of pedal feeling can be consistent with the vehicle test,and the evaluation method can correspond to the subjective feeling and guide the design.
