A kind of automobile intelligent speed limit system and automobile speed limit method

Abstract

The invention discloses an automobile intelligent speed limiting system and an automobile speed limiting method, and relates to the technical field of automobile safety driving assistance. The automobile intelligent speed limiting system and the automobile speed limiting method can improve accuracy of speed limiting identification recognition and improve driving safety of a driver. The automobile intelligent speed limiting system comprises a camera, an intelligent navigation device, an automobile body sensor and a controller, wherein the camera can recognize road traffic identification boards and extract road traffic identification information through the image processing technology, the intelligent navigation device can provide current road information, navigation route information and national or regional traffic road speed limiting law related information in real time, the automobile body sensor can provide automobile body information in real time, a traffic speed limiting identification database is set up in the controller, the input end of the controller is connected with the camera, the intelligent navigation device and the automobile body sensor, and the output end of the controller is connected with an automobile instrument and an engine ECU. The automobile intelligent speed limiting system is used for assisting in limiting the speed of the automobile.

Description

technical field [0001] The invention relates to the technical field of automobile safety driving assistance, in particular to an automobile intelligent speed-limiting system and an automobile speed-limiting method. Background technique [0002] With the increasing development of the automobile industry, automobiles have become the main means of transportation for people to travel. As the number of automobiles increases year by year, the construction of road infrastructure and the improvement of people's driving habits are relatively lagging behind. Casualties and property losses caused by traffic accidents are increasing year by year. Increase. In traffic accident statistics, traffic accidents and casualties caused by speeding account for a large proportion in all types of traffic accidents. The types of accidents caused by speeding are mainly rear-end collisions between vehicles and unilateral traffic accidents, which are likely to cause major accidents and extraordinarily...

AI Technical Summary

Problems solved by technology

[0005] ⑴. The speed limit device based only on the camera has poor adaptability to the region

Even if the same or similar speed limit signs can be accurately identified by the camera, the regulations or information hidden in the corresponding traffic signs in different countries or regions cannot be accurately identified only by the camera

For example, on a road section, the speed limit information implemented at different times of the day or in different seasons of the year is different, and the camera cannot recognize these hidden information;

[0006] ⑵. On road sections with multiple speed limit signs, the speed limit information suitable for the current vehicle cannot be accurately identified;

For example, the vehicle is about to change lanes or turn, and the speed limit sign on the current straight road is not suitable for the vehicle;

[0008] ⑷. The driver is the main body of vehicle control. The device ignores the driver's subjective wishes, and decelerating without reminding the driver of the vehicle's speeding will result in poor user experience and the risk of accidents

When the vehicle speed exceeds the speed limit sign, the device does not obviously limit the process of the vehicle continuing to overspeed and maintain the vehicle speed. Only by reducing the sensitivity of the accelerator, it is easy for the driver to ignore the risk of accidents caused by overspeeding.
