System and method for limiting vehicle speed

Abstract

The invention relates to a vehicle speed limit system, comprising a traffic speed limit indicator and a vehicle automatic over-speed governor, wherein the traffic speed limit indicator is used to transmit speed limit information and the vehicle automatic over-speed governor is used to limit the speed of vehicles. The invention also relates to a vehicle speed limit system, comprising a central processor and a vehicle automatic over-speed governor, wherein the central processor is used to deliver speed limit information, and the vehicle automatic over-speed governor which is connected with the central processor and is loaded on vehicles is used to limit the speed of vehicles. The invention further relates to a vehicle speed limit method, an information conversion module of the traffic speed limit indicator converses the speed limit information into short distance wireless signal sent by a short distance wireless signal transmitting module, the wireless signal processing module of the vehicle automatic over-speed governor receives the short distance wireless signal and analyzes the short distance wireless signal as speed limit information, and the speed limit information is prompted by a prompting module. The invention also relates to a vehicle speed limit method, a positioning module is used to measure vehicle position information, transmits the information to a central processor, and transfers the speed limit information in database, and the speed limit information is prompted by the prompting module, thereby realizing automatic speed limit control of vehicles.

Description

technical field [0001] The invention relates to a vehicle speed limiting system and method, in particular to an automatic vehicle speed limiting system and method, belonging to the field of wireless communication. Background technique [0002] Whether it is a road in a city or a road between cities, there will be a speed limit for vehicles under normal circumstances, but the speed limit of each road section is different, and it is impossible for drivers to remember the speed limit speed of all road sections, so now, on the road The current traffic speed limit information is presented to the driver through signs. When the driver is not paying attention, it is easy to miss the first instruction, which will lead to speeding violations and even serious traffic accidents. [0003] And if the display board is broken, or it is not easy to be seen, and on the same road section, the speed limit value will also change according to different road conditions (such as heavy fog, rain and...

AI Technical Summary

Problems solved by technology

It is necessary to pre-write the driving parameters in the memory, which not only increases the complexity of the operation, but also makes it difficult to pre-set when the vehicle is driving on an unfamiliar road section.

[0005] Therefore, there is no vehicle speed limit system and speed limit method at present, which can make the vehicle carry out speed limit according to the speed limit information of the current road section.
