基于EPBi系统的动态制动控制策略设计

Design of dynamic braking control strategy based on EPBi

为避免车辆在主动制动系统失效后,采用驻车制动系统制动时发生后轮抱死甩尾、侧翻等危险情况,提出了一种基于集成式电子驻车制动(EPBi)系统的动态制动控制策略.根据EPBi系统的相关特性,确定了卡钳的控制方式.结合实际路况,实现了智能化的控制方式,同时在装备了EPBi系统的实验车辆上对控制策略进行了各种路况下的实验验证.实车验证结果表明:所提出的动态制动控制策略满足企业和国家相关标准要求.

In order to avoid the dangerous circumstances of the rear wheel anti-locking tail and rollover when the vehicle braked using the parking brake (EPBi) system after the active brake system failed,a dynamic braking control strategy based on EPBi system was proposed in this paper.By determining the related parameters of the EPBi system caliper,the control method of the caliper was defined. What’s more,combining with the actual road conditions,the intelligent braking method was realized.At the same time,the experimental strategy under various road conditions was verified on the experimental vehicle equipped with EPBi system.The results of the experiments showed that the dynamic braking control strategy proposed can satisfy enterprise standards and national standards.
