摘要
针对某4×4越野车液压助力制动系统的结构和特点,设计了一套双回路电控-液压制动系统,在保留车辆有人驾驶模式下踩踏板制动功能的同时,实现其在无人驾驶模式下的电控制动功能,且两种模式能够无缝切换.其中,有人驾驶模式的优先级高于无人驾驶模式.在某4×4越野车上搭建实车系统,通过静态试验和实际道路试验,测试其响应特性和控制特性,在此基础上,进行电控制动试验.结果表明,设计的双回路电控-液压制动系统能够满足车辆无人驾驶的要求.
A double circuit electrical hydraulic braking （EHB） system was developed, in consideration of the structures and features of hydraulic power braking of a four-wheel drive off- road vehicle. The system could implement electrical brake at the autonomous mode and pedal brake at the manual mode. Meanwhile, the two modes could be switched seamlessly, and the manual mode showed a higher priority than the autonomous mode. The system was applied to a four-wheel drive off-road vehicle. Static and real world tests were carried out to obtain the biasing and response characteristics of the system. On this basis, electrical braking tests were conducted. Experiment results show that the EHB system can meet the requirements of an autonomous vehicle.
