Vehicular anti-collision early-warning system

Abstract

The invention discloses a vehicle anti-collision early warning system, which includes a basic information collection module: to obtain vehicle size data related to the vehicle type; a direction information collection module: to obtain the turning angle of the vehicle when turning; a speed measurement module: to obtain the driving speed of the vehicle; distance measurement Module: when the vehicle is going straight, detect the distance between the vehicle's front or rear obstacles and the vehicle, and when the vehicle is turning, detect the distance between the vehicle's side obstacles and the vehicle; collision risk calculation module: evaluate the vehicle based on the data provided by the above modules Risk of collision with obstacles; early warning and reminder module: when the vehicle is at risk of collision with obstacles, an early warning is issued to the driver. The present invention can accurately and effectively evaluate and remind possible collision risks under various driving states of the vehicle, and can effectively avoid the occurrence of collision accidents.

Description

[technical field] [0001] The invention relates to an automobile safety driving assistance technology, in particular to a vehicle anti-collision warning system. [Background technique] [0002] Most of the car collision accidents are caused by the driver's inaccurate estimation of the distance around the vehicle, misjudgment of the possibility of collision, untimely braking, or vehicle blind spots and other factors. The blind spot of a vehicle refers to the part where the driver is located in the normal driver's seat and whose line of sight is blocked by the car body and cannot be directly observed. Due to the design requirements of the car body, the A, B, and C pillars of the car are usually thicker, and the rearview mirror is smaller. Therefore, vehicles usually have A, B, and C pillar blind spots, rearview mirror blind spots, front and rear blind spots, etc. When the vehicle is going straight, changing lanes, reversing, turning, etc., the driver will have a certain visual...

Problems solved by technology

[0005] However, there are many states when the vehicle is driving, such as going straight, turning, changing lanes, overtaking, reversing, etc. The existing technology uses cameras or radar sensors to detect moving targets in front of and behind the vehicle, and calculates the distance and relative speed. , Reminders are given when the vehicle behind has a collision risk, but when the vehicle turns, the distance and relative speed of pedestrians and vehicles on the inner side of the vehicle turn have not changed, so the above method cannot be applied

Moreover, due to the maneuverability of the vehicle, when the vehicle is turning, there will be inner wheel difference and rear suspension deviation, which may cause the vehicle to drive off the road or cause a collision accident during driving.

Existing vehicle anti-collision technology cannot give early warning of possible scratches and collision risks when the vehicle is turning
