Problems solved by technology

[0011] This method has a certain warning effect on the driver's speeding, so that the driver should try not to drive over the speed limit on the road section with a radar speed measurement area, but it cannot play a warning role on the entire road section
[0012] It can be seen that there is currently a lack of a method and device for expressway lane-dividing speed limit automatic alarm prompts

Abstract

The invention relates to a vehicle overspeed detection alarm system and a vehicle overspeed detection method thereof. The vehicle overspeed detection alarm system comprises a vehicle overspeed detection device, an alarm device, a first camera device, a second camera device and a third camera device, wherein the first camera device, the second camera device and the third camera device are arranged on a vehicle, and are respectively in communication connection and / or electric connection to the vehicle overspeed detection device and transmit shot lane images to the vehicle overspeed detection device; and the vehicle overspeed detection device is in communication connection and / or electric connection to the alarm device, and used for controlling the alarm device to send alarm when the vehicle is overspeed.

Description

technical field [0001] The invention relates to the technical field of automotive electronic control related to safe driving of vehicles, in particular to a road condition sign scanning recognition, overspeed detection and alarm system and a vehicle overspeed detection method. Background technique [0002] According to relevant national regulations, the maximum speed limit on expressways is 120km / h. But what is mentioned here is that the maximum speed limit is 120km / h. In our actual driving, each expressway, even each lane, and each block has a different speed limit. Generally, the innermost lane of domestic expressways has a speed limit of 120km / h, and then the speed of the outward lanes decreases in turn. Vehicles should go their own way, and the speed of the vehicle should be controlled within the speed limit corresponding to the driving section, otherwise speeding or even traffic accidents may occur. [0003] In order to keep the vehicle running normally, the following...
