影响行车安全的主要技术因素表现为汽车的制动、转向效能对行车安全有直接的影响,传动、行走效能、汽车的外廓结构参数、油(电)路及汽车启动性对行车安全有关联的影响。 一、制动效能的影响 制动的正常效能,应使行驶的汽车按需要减速或停车。这种效能是经过制动系各装置的正常作用相互协调实现的。当其中有一环节出现问题,不能正常地作用时,便会对行车安全构成不同程度的威胁。其中主要是制动失效、制动距离过长、制 The main technical factors affecting traffic safety are the braking of the vehicle. The steering efficiency has a direct impact on the driving safety. The transmission and running performance, the structural parameters of the vehicle, the oil (electricity) road and the car starting are related to driving safety Impact. First, the braking effect of the normal braking performance, should be driven by the need to slow down or stop the car. This efficiency is through the braking system of the normal role of each device to achieve coordination. When a problem occurs in a part of the work, it can pose different levels of threat to driving safety when it can not function normally. Which is the main brake failure, braking distance is too long, the system
