| 摘 要： | 针对传统液压制动系统应用场景受限的问题，面向智能车设计新型电子液压制动系统，由车辆配备的智能驾驶系统将制动信号传递给制动系统，制动系统由助力制动子系统和备份制动子系统组成，两系统之间通过单向导通梭阀完成解耦。利用系统硬件在环实验，分析电子液压制动系统的动态特性。实验结果表明:影响电子液压制动系统建压响应性与精度的因素众多，为使得系统可以快速响应，应确保整车制动管路排气良好，尽量避免使用制动软管?同时，不宜长时间进行高压力保压工况，避免电机及电机驱动器过热从而降低制动效能。

| Abstract: | Aiming at the limited application scenarios of the traditional hydraulic braking system, a new type of electronic hydraulic braking system was designed for the intelligent vehicle. The intelligent driving system equipped on the vehicle transmits the braking signal to the brake system, which consists of an assist braking subsystem and a backup braking subsystem. The decoupling between the two systems is accomplished via a single-guide shuttle valve. The dynamic characteristics of the electronic hydraulic braking system were analyzed by using hardware-in-the-loop-experiment. Experimental results show that there are many factors that affect the responsiveness and accuracy of the electronic hydraulic braking system, and in order to allow the system to respond quickly, it has to be ensured that the vehicle brake lines are exhausted well and the use of brake hoses is avoided as much as possible. At the same time, it is not advisable to carry out high pressure keeping conditions for long periods of time, so as to avoid overheating of motors and motor drivers, thereby reducing braking efficiency. |
