Vehicle active speed limiting control system and control method

Abstract

The invention discloses a vehicle active speed limiting controlling system and a controlling method and relates to the field of automobile safe driving controlling. The system comprises a steering wheel control button, a speed limiting value obtaining module, a speed limiting controller and an engine. The steering wheel control button is used for selecting one of a normal driving mode, a general speed limiting mode and a map speed limiting mode. The speed limiting value obtaining module is used for obtaining a speed limiting value. The speed limiting controller is used for conducting comprehensive treatment and calculation by combining a real-time vehicle speed value and the speed limiting valve according to the function mode to achieve a vehicle automatic speed limiting function. One of the normal driving mode, the general speed limiting mode and the map speed limiting mode can be independently selected according to the requirement, selection is flexible, multiple control modes are switched freely, and convenience and rapidness are achieved. When the map speed limiting mode is selected, the vehicle speed is limited automatically according to the speed limiting value in a GPS navigation host, the automatic speed limiting function of the system is achieved, driving convenience is improved, and violation or a traffic accident caused by overspeed is reduced effectively.

Description

technical field [0001] The invention relates to the field of automobile safety driving control, in particular to a vehicle active speed limit control system and control method. Background technique [0002] With the development of the automobile industry, the safety driving technology of automobiles has gradually matured. Existing roads have more and more speed restrictions on cars and are becoming more and more complicated, and many drivers do not pay much attention to road rules, and drive faster and faster. On the one hand, it is easy to cause traffic accidents and cause great safety hazards. On the other hand, it is easy to exceed the prescribed speed limit and cause violations, which need to be deducted points, fined, and more seriously, the driver's license will be revoked, which will bring great trouble to drivers. [0003] At present, most of the cars on the market have a speed limit function, but the speed limit function is basically based on the driver's own setti...

AI Technical Summary

Problems solved by technology

However, the speed limit values ​​stipulated on different roads are constantly changing, and even the speed limit values ​​in different places on the same road are constantly changing. value will be very troublesome

Therefore, the speed limit system of the prior art can only set a maximum speed limit value, and the driver can adjust the vehicle speed independently according to the speed limit prompt on the navigation or the speed limit sign, so it is difficult to achieve the automatic speed limit function of the vehicle.
