Problems solved by technology

Among the many traffic accidents that occur every year, a large part is due to (heavy fog, heavy rain, haze) weather reasons, or driving at night, etc., which will affect the driver's sight and understanding of the situation in front of the car, which can easily cause traffic accidents make
The current vehicle prevention system mainly detects the distance between vehicles through the distance detector, and reminds the driver after the detection distance is less than the preset safe distance. This preset safe distance cannot be set according to the actual situation of the vehicle. As the load on the vehicle increases, it will directly affect the length of the safety distance, so the preset safety distance for this week cannot accurately preset the real safety distance

Embodiment 1

[0035] Such as figure 1 As shown, the system for preventing vehicle traffic accidents includes a weight acquisition module, a vehicle speed detection module, a vehicle kinetic energy calculation module, a vehicle distance detection module, a system controller, a prompt module and a mandatory braking module, and the vehicle kinetic energy calculation module respectively connected with the weight acquisition module and the vehicle speed detection module, and the system controller is respectively connected with the vehicle kinetic energy calculation module, the vehicle distance detection module, the prompt module and the forced braking module;

[0036] The weight acquisition module is used to detect the weight of the vehicle in real time;

[0037] The vehicle speed detection module is used to detect the speed of the vehicle in real time;

[0038] The vehicle kinetic energy calculation module is used to calculate the kinetic energy of the vehicle in combination with weight and sp...

Embodiment 2

[0058] Such as figure 2 As shown, the method for preventing vehicle traffic accidents includes the following steps:

[0059] S1. Detect the weight and speed of the vehicle in real time, as well as the distance to the vehicle in front of the vehicle, and calculate the kinetic energy of the vehicle according to the weight and speed.

[0060] Wherein, the step of real-time detection of the vehicle-ahead distance in front of the vehicle described in step S1 is specifically: after collecting images in front of the vehicle in real time using infrared imaging technology, calculating the vehicle-ahead distance according to the collected images.

[0061] S2. After calculating the safe vehicle distance of the vehicle based on the kinetic energy of the vehicle and preset braking parameters, it is judged whether the distance of the vehicle ahead is smaller than the safe distance between vehicles, and when it is judged that the distance of the vehicle ahead is smaller than the safe distan...

Abstract

The invention discloses a system and method for preventing a vehicle traffic accident. The method comprises the following steps: real-time detecting the weight and speed of the vehicle, and the distance in front of the vehicle, and calculating the kinetic energy of the vehicle according to the weight and the speed; combining the kinetic energy of the vehicle with the preset braking parameters to calculte the safe distance of the vehicle, and determining whether the distance of the front vehicle is less than the safe distance of the vehicle, and prompting the driver to reduce the speed when thedistance of the front vehicle is judged to be less than the safe distance of the vehicle,; determining whether the vehicle speed is reduced or not, and after judging that the vehicle speed is not reduced, forcing the speed of the vehicle to be reduced until the distance before the vehicle is greater than the safe distance. The invention calculates the safe distance of the vehicle by the momentumof the vehicle and the braking parameters, and calculate the safe distance according to the actual situation of the vehicle, make the safe distance more accurate, then actively force to reduce the speed of the vehicle after detecting the prompt deceleration of the vehicle has not decelerated, , effectively improve the active safety of the automobile, can be widely used in the field of automobile safety technology.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a system and method for preventing vehicle traffic accidents. Background technique [0002] With the continuous development of the social economy and the gradual improvement of people's living standards, cars have become the main means of transportation in daily life. As of the end of March 2017, the number of motor vehicles exceeded 300 million for the first time, of which the number of cars exceeded 200 million for the first time. The number of motor vehicle drivers has exceeded 364 million. With more people driving, there will inevitably be more traffic accidents on the road. The latest research report shows that the number of deaths caused by traffic accidents in 2017 was about 63,000, while in 2016 a total of 8.643 million road traffic accidents were reported, a year-on-year increase of 659,000 cases, an increase of 16.5%. Among them, there were 212,846 road traf...
