Abstract

The invention discloses a system and method for measuring the distance and speed of vehicles ahead in real time. The system comprises a measuring module and a processing module, wherein the measuring module is composed of a first ultrasonic sensor, a second ultrasonic sensor and a Hall sensor, and the processing module is composed of an input module and a controller. The system can further comprise a prompt module which is composed of a displayer and a voice system, wherein the first ultrasonic sensor, the second ultrasonic sensor, the Hall sensor, the input module, the displayer and the voice system are connected with the controller. Summarily, the method includes the steps that the controller processes data, and the distance and speed of the vehicles ahead are obtained and displayed on the displayer; meanwhile, the controller judges whether the distance and the speed exceed safety threshold values, and if yes, the voice system gives a voice prompt. By means of the system and the method, the distance between vehicles and the speed of the vehicles ahead can be measured in real time in the moving state of the own vehicle and the vehicles ahead, the prompt is given to a driver, and thus traffic safety is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle speed measurement and distance measurement, and more particularly, to a measurement system and method for real-time measurement of the distance and speed of the vehicle ahead. Background technique [0002] A large number of traffic accidents have been statistically analyzed, and automobile rear-end collision accidents account for a considerable proportion of the total number of traffic accidents. The main reason for rear-end collisions is that the distance between the two vehicles is not maintained enough. In order to ensure driving safety, it is necessary to measure the distance and speed of the vehicle ahead and remind the driver. [0003] The methods of vehicle distance measurement include radar distance measurement, laser distance measurement and video distance measurement. Radar ranging and laser ranging equipment are expensive, and one side must be in a static state. Video ranging is affected by il...
