基于整车道路测试的几次ABS事故分析

摘要

Several ABS test data was investigated, pointed out that the difference of wheel speed can lead to failure of ABS test. When left wheel speed was faster or slower than right wheel, vehicle would transverse sway and slip out from the initial lane. When rear wheel speed was slower than front wheel, the braking stability would be deteriorated and vehicle was prone to whipping. According to the test data and the subjective evaluation of driver, an evaluation method of road test and some suggestion were given out.%分析了几次ABS测试不合格的试验数据，指出轮速差异过大是造成ABS不合格的主要原因。主要体现为两方面：左右轮速差异对车辆横摆有不利影响，易造成车辆滑出规定的车道宽度；前后轮速差异中的后轮过度制动则会恶化车辆的制动稳定性，易造成甩尾等严重事故。根据积累的各种数据和驾驶员主观感受，提出整车道路测试时的风险评估方法，并给出几起ABS不合格的改进建议。
