Automatic vehicle speed limit control system and control method

Abstract

The invention discloses an automatic vehicle speed limit control system and control method. The automatic vehicle speed limit control system comprises an automatic speed limit controller and a remote control center. The automatic speed limit controller comprises a central processor, a satellite positioning device, a wireless communication module, a speed limit database, a vehicle communication module and an overspeed alarming module, wherein the satellite positioning device, the wireless communication module, the speed limit database, the vehicle communication module and the overspeed alarming module are connected with the central processor, the satellite positioning device acquires longitude and latitude information and time information of a vehicle and transmits the longitude and latitude information and the time information to the central processor, the central processor is in communication connection with the remote control center through the wireless communication module, the vehicle communication module acquires working states of the vehicle and provides the working states of the vehicle to the central processor, speed limit values matched with the longitude and latitude information and the time information of the vehicle are prestored in the speed limit database, and the central processor is connected with an engine through a bus. Compared with the prior art, additional modification does not need to be carried out on the vehicle, a sensor does not need to be added either, key systems such as throttle control are not changed, and extreme convenience is achieved.

Description

technical field [0001] The present invention relates to the field of automobile active safety, and more specifically relates to a vehicle automatic speed limit control system and control method, which intelligently adjusts the vehicle speed limit value and implements vehicle speed control in combination with Internet of Vehicles, environmental perception and various information. Background technique [0002] As the most commonly used means of transportation in modern society, automobiles must be regarded as the top priority. According to the analysis results of major road traffic accidents in recent years, the direct causes of the accidents are all related to the traffic violations of drivers. Various factors in descending order of proportion are speeding, improper operation, overcrowded passenger cars, overloaded trucks, illegally occupying the road, fatigue driving, illegal overtaking, improper braking, drunk driving, and failure to yield according to regulations, etc. At...

AI Technical Summary

Problems solved by technology

These technologies are relatively complicated in terms of vehicle speed control and environmental perception. The installation and realization of the device is especially difficult for vehicles after leaving the factory, and the scope of application is small, so it cannot be implemented on a large number of vehicles currently in operation, and generally there is no driving As one of the factors that affect the safe driving speed, at the same time, the system relies heavily on the road speed limit, and cannot flexibly adapt to the speed limit caused by other reasons
