Traffic condition prediction reminding device and method for vehicles

Abstract

The invention provides a traffic condition prediction reminding device and method for vehicles, and belongs to the technical field of vehicles. The traffic condition prediction reminding device and method solve the problem that whether the vehicles can pass before a red light is on can not be accurately judged in the prior art. The traffic condition prediction reminding device for the vehicles comprises a vehicle-mounted navigator, a vehicle speed sensor, a voice reminding mechanism and a controller, wherein the vehicle-mounted navigator and the vehicle speed sensor are connected with the input end of the controller, and the voice reminding mechanism is connected with the output end of the controller. The traffic condition prediction reminding method for the vehicles comprises the steps of presetting the time rule function of the traffic light of each road intersection; calculating the time for reaching the road intersection with the traffic light according to the distance to the road intersection with the traffic light and the driving speed; calculating out the condition of the traffic light at the time point in the previous step according to the time rule function of the traffic light, and outputting corresponding control signals to the voice reminding mechanism to remind a driver. According to the reminding device and method, the traffic condition of the road intersection with the traffic light can be accurately predicted.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a vehicle traffic condition prediction and prompting device and method. Background technique [0002] Traffic safety has increasingly become a focus of human society. Behaviors such as vehicles running red lights have caused serious traffic safety hazards, and sometimes even lead to major accidents. Some drivers ignore the traffic safety and intentionally run the red light, and some drivers mistakenly think that the vehicle can still pass through the green light due to miscalculation of the time and distance when the green light is about to end. Red light, and now the traffic management is becoming more and more strict. In the latest traffic regulations, 6 points are deducted for running a red light. That is, a driver’s license can’t be used once a red light is run. device is very necessary. [0003] In view of the above-mentioned problems, the existing Chinese patent litera...

Problems solved by technology

The car anti-running red light control device can automatically brake and stop in front of the zebra crossing when the red light is on, but the camera device in the control device has limitations. The information calculates the distance between the front of the car and the zebra crossing, so it is impossible to judge whether it can pass before the red light is on, the judgment is not accurate enough, and it cannot serve as a good reminder
