System and method for automatic vehicle collision protection

Abstract

The present application relates to the field of vehicle protection, in particular to an automatic vehicle collision protection system and method, wherein the protection system includes a sensing device, a control device and a braking device; the sensing device includes a contact sensor and a crush structure, and the contact type The sensor is used to sense the collision to generate a collision signal when the vehicle collides, and the collapse structure is used to generate deformation and absorb the impact force of the collision when the vehicle collides; the control device receives the collision signal and generates a brake that lasts for a preset time based on the collision signal Signal; the braking device brakes the vehicle based on the braking signal, and can automatically brake after the vehicle collides to prevent secondary collisions, reduce risks, and reduce losses.

Description

technical field [0001] The present application relates to the field of vehicle protection, in particular to an automatic vehicle collision protection system and method. Background technique [0002] In the field of vehicles, there is a risk of the vehicle colliding with an obstacle, especially if the vehicle's anti-collision system fails. If a collision occurs, it is desirable to have the vehicle brake immediately. But if the obstacle is bounced off by the vehicle, the vehicle may not stop, so a secondary collision may occur, causing greater damage. In the prior art, the vehicle can detect the collision signal when the collision occurs. If the obstacle is not bounced off, the vehicle can detect the continuous collision signal and take braking measures; but if the obstacle is bounced off, the collision signal continues If the time is too short, it is not enough for the vehicle to start the braking action, and the vehicle cannot stop moving forward. Especially in the field of...

But if the obstacle is bounced by the vehicle, the vehicle may not stop moving forward, which may cause a secondary collision, causing greater damage

In the prior art, the vehicle can detect the collision signal when the collision occurs. If the obstacle is not bounced off, the vehicle can detect the continuous collision signal and take braking measures; but if the obstacle is bounced off, the collision signal continues The time is too short for the vehicle to start the braking action, and the vehicle cannot stop moving forward, especially in the field of unmanned vehicles. After the collision, there is a risk of secondary collision because no driver actively brakes.
