Problems solved by technology

[0002] The "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" imposes speed limits on different roads based on conditions such as road category, traffic volume, road width, and barrier conditions. Vehicle speeding will cause the driver's vision to become smaller and the driver's reaction The driving distance of the vehicle increases during the time, and the braking distance increases
Increase the probability of accidents, aggravate the severity of accidents, and affect vehicle safety performance
In reality, in the same place, especially on expressways, the speed limit of different lanes may be different, and the existing speeding reminder system cannot provide drivers with accurate speed limit information

[0044] refer to figure 1 , is the first embodiment of the vehicle speeding reminder method of the present invention. On the expressway, the vehicle speeding reminder method includes a high-speed speed limit acquisition step S1;

[0045] The high-speed speed limit acquisition step S1 includes:

[0046] Step S110, collecting images of the road ahead of the vehicle.

[0047] Use a camera to capture images of the road ahead of the vehicle. The camera can be a camera mounted on the windshield facing the road ahead of the vehicle, or a driving recorder. When the vehicle starts to drive, the camera or driving recorder is automatically activated or artificially Start the operation and take pictures of the road ahead of the vehicle. Of course, it is not limited to these methods.

Abstract

The invention discloses a vehicle overspeed reminding method and system. The method includes the steps that on an express way, an image of the way ahead of a vehicle is collected; the number of lanes and the lane where the vehicle is located are acquired according to the image; vehicle type information of the vehicle is acquired; the speed limit value of the vehicle is acquired according to the mapping relation between the number of the lanes, the lane where the vehicle is located and the vehicle type information of the vehicle and those in a pre-stored express way information table; the real-time speed of the vehicle is measured; whether the real-time speed of the vehicle is larger than the speed limit value or not is judged, and if yes, an overspeed reminding message is sent out. According to the vehicle overspeed reminding method and system, on the express way, the image of the way ahead of the vehicle is analyzed to acquire the number of the lanes and the lane where the vehicle is located currently, the speed limit value can be dynamically adjusted according to the lane where the vehicle is located currently, and precise speed limit information can be acquired.

Description

technical field [0001] The invention relates to the field of automobile safety driving assistance, in particular to a vehicle speeding reminder method and system. Background technique [0002] The "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" imposes speed limits on different roads based on conditions such as road category, traffic volume, road width, and barrier conditions. Vehicle speeding will cause the driver's vision to become smaller and the driver's reaction The vehicle travel distance increases within the time, and the braking distance increases. Increase the probability of accidents, aggravate the severity of accidents, and affect the safety performance of vehicles. In reality, in the same place, especially on the expressway, the speed limit of different lanes may be different, and the existing speeding reminder system cannot provide accurate speed limit information for drivers.
