Automobile collision avoidance system capable of reducing collision damage

Abstract

The invention discloses an automobile collision avoidance system capable of reducing collision damage. The automobile collision avoidance system capable of reducing the collision damage is characterized by comprising an automobile state detection unit, an environment detection unit, a central control system, a steering control unit, a brake control unit and a protection device; three protection levels of a safety state, an emergency controllable state and an imminent collision state are set; in the imminent collision state, the avoidance route is planed according to the current automobile angular velocity measured by an automobile angular velocity sensor, automobile accelerated velocity measured by an automobile accelerated velocity sensor, relative distance and relative velocity; the collision area is estimated according to predicated collision part; and the steering control unit and the brake control unit automatically intervene through the central control system to implement avoidance. The avoidance logic is that the priority level of side collision of the automobile head or the automobile tail is higher than that of the front collision of the automobile head or the automobile tail and the collision area is small as much as possible; during avoidance, the central control system distributes four steering angles to hub motor controllers of four wheels in real time according tothe collision part and the estimated collision area, and each wheel singly steers; and when a collision occurs, the protection device is started.

Description

Technical field [0001] The application relates to the field of automobile collisions, and in particular to an automobile anti-collision system that reduces collision damage. Background technique [0002] With the increase in the number of vehicles in my country, there are more and more traffic accidents, especially traffic accidents on highways are fatal. Therefore, research on automobile anti-collision technology has become a hot spot, mainly including active anti-collision technology and passive anti-collision technology. Active anti-collision technology mainly studies how to avoid collisions. Under the situation of continuous advancement of artificial intelligence technology, it takes time for humans to respond in emergencies. Through the detection of the environment and accurate data analysis, the machine is assigned to control the steering and control of the vehicle. Instead, it is more beneficial. In addition, the anti-collision methods in the prior art only consider how t...

AI Technical Summary

Problems solved by technology

In addition, the anti-collision methods in the prior art only consider how to protect the passengers during a collision, and do not further consider the damage to the car.

When the vehicle collides, the direct frontal collision of the front or rear of the vehicle will cause huge damage to the body and chassis, and it is difficult to repair. Therefore, the collision cost is extremely high, whereas the side collision damage is relatively small
