交通事故的发生与车辆行驶速度关系密切,过去认定速度都以车辆制动时所产生的轮胎的痕迹为主要计算依据。然而从上世纪50年代迄今已超过半个世纪,汽车工业之发展随着科技进步而突飞猛进,实非同日而语,尤其在安全配备上已达可无人驾驶之境界,其中制动系统的研制更是多元而细腻。由于制动系统的不同,制动方式的差 The occurrence of traffic accidents is closely related to the speed of vehicles. In the past, the speed of traffic accidents was mainly based on the traces of the tires produced when the vehicle was braking. However, from the 1950s to the present, more than half a century has passed since the development of the automotive industry has progressed rapidly with advances in science and technology. In fact, the development of the braking system has become unmanned, especially in the field of safety equipment It is more diverse and delicate. Due to the different braking system, poor braking
