Embodiment 1

[0042] exist figure 1 In the shown embodiment 1, a car side collision prevention mitigation system is used to avoid the occurrence of car side collisions to the greatest extent or reduce the damage caused by car side collisions. The car side collision prevention mitigation system includes: radar Distance measuring system, anti-collision control unit, vehicle speed control system, vehicle speed sensor, alarm unit and airbag control unit, of which:

[0043] Radar ranging system, including front ranging radar, rear ranging radar, left ranging radar and right ranging radar, used to measure the real-time distance between the vehicle and the front vehicle, rear vehicle, left vehicle and right vehicle respectively. Distance; the front ranging radar is arranged at the front of the car, the rear ranging radar is arranged at the rear of the car, and the left ranging radar and the right ranging radar are respectively arranged at the left and right sides of the middle part of the car.

...

Embodiment 2

[0061] exist figure 2 In the shown embodiment 2, the vehicle anti-side collision mitigation system also includes:

[0062] The tire burst monitoring unit is used to provide the tire burst data to the anti-collision control unit when a tire burst accident occurs in the vehicle; the rest is the same as that of embodiment 1.

[0063] In addition to the method described in embodiment 1, the control method of the automobile side collision prevention mitigation system of embodiment 2 also includes the following steps:

[0064] When the car has a puncture, the puncture monitoring unit provides the puncture data to the anti-collision control unit, and the anti-collision control unit automatically transfers to the puncture processing program. The puncture processing program passes the detected distance between the vehicle and the rear vehicle and the relative speed to calculate the possible collision time with the rear vehicle. When the possible collision time between the vehicle and...

Embodiment 3

[0066] exist image 3 In the shown embodiment 3, the automobile side collision prevention mitigation system also includes a door and window control unit, which is used to automatically lock the automobile doors and windows on the side where the collision is predicted to occur when the automobile may be in danger according to the instructions of the anti-collision control unit, specifically: When the possible collision time between the vehicle and the vehicle on the left or / and the vehicle on the right is less than 1 second, the anti-collision control unit automatically locks the doors and windows on the side where the collision may occur through the door and window control unit, that is, when the vehicle may collide with the vehicle on the left When colliding, lock the doors and windows on the left side of the car; when the car may collide with the right side car, lock the doors and windows on the right side of the car; when both sides may collide, lock the doors and windows on...

Abstract

The invention discloses an automatic side-collision prevention mitigating system and a control method, which are used for avoiding automobile side-collision or lightening damages caused by the side-collision to the utmost extent; the automotive side-collision prevention mitigating system comprises a radar ranging system, a collision-prevention control unit, a speed control system, a speed sensor,an alarming unit, a pre-tightened safety belt control unit and an airbag control unit; the collision-prevention control unit is used for calculating relative speed of the automobile in relation with a left automobile and / or a right automobile according to distance data provided by the radar ranging system, judging whether the collision occurs and the possible occurrence time of collision according to the length and the speed of the automobile, and sending corresponding instructions to actuating mechanisms according to preset programs, and controlling the operations of the automobile such as alarming and acceleration, so that the automobile side-collision is avoided or the damages resulting from the automobile side-collision are lightened to the utmost extent.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile side collision prevention and mitigation system and a control method that can avoid automobile side collisions to the greatest extent or reduce automobile side collision damage. Background technique [0002] In traffic accidents, side collisions are a frequent form of accidents. Side collisions generally occur at intersections, changing lanes and overtaking other vehicles, and because there are fewer energy-absorbing areas on the side of the car, collision accidents are often serious. For vehicles The damage is also relatively large, and the maintenance cost is high. How to effectively monitor the environmental conditions on both sides of the vehicle and control the movement of the vehicle through algorithms is the key to effectively preventing side collisions. But most of the anti-collision warning systems in the prior art have considered the possible col...
