Intelligent detection control device and method of safe interval

Abstract

The invention relates to intelligent detection control device and method of safe interval. The device comprises a binocular pinhole camera, a signal processor, a vehicle speed control mechanism and a voice prompter. An output interface of the binocular pinhole camera is respectively connected with two image input interfaces of the signal processor through a video cable; and an output interface ofthe signal processor is connected in parallel with an input interface of the vehicle speed control mechanism and an input interface of the voice prompter. In the method, the vehicle distance from thefront vehicle is automatically detected, and the kept safe distance is accurately controlled according to the speed of the vehicle. The invention ensures that the speed is reduced in a real-way and accurate way until braking according to the current vehicle speed and the interval, thereby effectively avoiding traffic accidents such as tailgate. The counting data in the implementation result showsthat the tailgate accident can be reduced by above 95%.

Description

technical field [0001] The present invention relates to a device and method in the field of control technology in automobile engineering, in particular to a device and method for intelligent detection and control of safe distance between vehicles. Background technique [0002] Maintaining a certain distance between front and rear vehicles is a problem that must be paid attention to and mastered in safe driving, especially for cars driving on expressways. However, if the driver controls the safe vehicle distance, there are obviously the following fatal weaknesses: [0003] (1) It is difficult to grasp the accurate vehicle distance by visual inspection; [0004] (2) On the expressway, for ordinary drivers, it is absolutely impossible to accurately "mentally calculate" the best safe distance with the vehicle in front according to the current speed of the vehicle; [0005] (3) Affected by factors such as driving experience and driving psychology, it may cause negligence of the...
