The invention provides an automatic safety device of an automobile. Firstly, a speed detector detects the current speed of the automobile, and an infrared distance sensor detects a current distance between the automobile and an obstacle at the front end of the automobile, then calculates a shortest braking distance according to the detected current speed and distance, and adds a preset buffer distance and a preset isolation distance to the shortest braking distance to obtain a warning distance and a braking distance of the automobile respectively; when the distance between the automobile and the obstacle at the front end of the automobile is smaller than or equal to the warning distance of the automobile, a driver is warned; and when the distance between the automobile and the obstacle atthe front end of the automobile is smaller than or equal to the braking distance of the automobile, a brake control system of the automobile automatically brakes the automobile. Traffic accidents canbe effectively avoided.
本发明提供了一种汽车自动安全装置,首先速度检测器检测汽车的当前速度,红外距离感应器探测汽车与其前端障碍物之间的当前距离,然后根据探测到的当前速度和距离,计算出最短制动距离,将最短制动距离加上预设的缓冲距离和隔离距离,分别得到汽车的警告距离和刹车距离;当汽车与其前端障碍物之间的距离小于等于汽车的警告距离时,对驾驶员发出警告;当汽车与其前端障碍物之间的距离小于等于汽车的刹车距离时,则汽车的刹车控制系统自动对汽车进行刹车。本发明能够有效地避免车祸的发生。
