Abstract

With the increasing number of low-speed electric vehicles in China, their safety performance has been widely concerned. In order to explore the braking safety performance of domestic low-speed electric vehicles, six sample vehicles (including new vehicles and in-service vehicles) of three brands were selected, and the braking performance of the sample vehicles was evaluated through road test and bench test. Firstly, the vehicle braking time, braking distance and braking speed curve are collected by VBOX and portable braking performance tester, and then the wheel braking force is detected by using the counter-force roller braking test bench. According to the comprehensive analysis of the test data, it is determined whether the braking performance of the tested vehicle meets the relevant technical standards. The test results show that some low-speed electric vehicles have obvious deviation and sideslip when braking at medium and high speeds, and their braking directional stability is unqualified, and the causes of vehicle braking deviation and sideslip have been analyzed and determined. The research work in this paper will been of a certain guiding significance for improving the braking safety of low-speed electric vehicles.
