车距的自动测量及控制原理

Automatic Measuring and Controlling Principles of the Following Distance of Vehicles

采用超声波传感器测量行驶中两车之间的距离,同时通过测量后车车速并根据驾驶员的反应时间而设计出一种自动控制装置,防止交通事故的发生。

How to use the supersonic sensor to measure the distance between two vehicles is talked about here. An automatic control device is worked out to prevent traffic accidents according to the measured vehicle velocity afterwards and the driver's reaction time to handle the vehicle.
