为测试高温、常温不同气温条件下汽车制动性能的变化,本文开展了重庆市不同气温条件、不同初始速度下的汽车制动试验,并对测试结果进行分析。结果表明高温条件下制动距离增大,充分发出的平均减速度(MFDD)减小,制动性能有所降低。这为驾驶员在行车过程中的制动动作提供实践基础。
In order to test the braking performance of automobile under different temperatures and temperatures, this paper carried out automobile braking tests under different temperature conditions and different initial speeds in Chongqing, and analyzed the test results. The results show that under high temperature conditions, the braking distance increases, the full MFDD decreases, and the braking performance decreases. This provides a practical basis for the driver to brake during driving.
