汽车防撞系统设计

为了防止车辆发生碰撞事故，降低交通事故的发生频率。系统利用红外探测模块对所驾驶的车辆前方的行人及其他机动车行驶时发动机所发出的红外线感应，检测是否有车或行人。在红外探测模块不适宜检测人的温度点启动超声波探测模块辅助检测是否有行人。根据红外探测模块或超声波辅助探测模块的检测结果自动控制警报发出或解除、自动刹车或刹车解除以及汽车离合器的分开或啮合,从而实现汽车防撞的智能化控制。

Design of automobile collision prevention system

The aim of this system was to prevent the vehicles from collision and to reduce the frequency of traffic accidents. The infrared detection module was used to detect the infrared which was radiated by the pedestrian and other motor vehicles when the engine was running, thus whether there were cars or pedestrians in front of the vehicle driven could be judged. At the temperature point where the infrared detection module was not suitable for human detection, the ultrasonic detection module was started to assist in the detection of pedestrians. According to the detection results of infrared detection module or ultrasonic assisted detection module, the following actions were automatically implemented: the issue or release of alarm, the autobrake or released, and the disengagement or engagement of car clutch. Consequently, the intelligent control of automobile collision prevention could be realized.
