Embodiment 1

[0036] exist figure 1 In the shown embodiment 1, a car longitudinal collision mitigation system is used to avoid car collision to the greatest extent or reduce the damage caused by car collision. The car longitudinal collision mitigation system includes a radar ranging system, a collision avoidance control unit . Vehicle speed control system and alarm unit, wherein:

[0037] The radar ranging system includes a front ranging radar and a rear ranging radar. The front ranging radar and the rear ranging radar are respectively installed at the front and rear of the car, and are used to measure the distance between the vehicle and the vehicle in front and the rear in the same lane. The real-time distance between the vehicle and the following vehicle in the same lane;

[0038] The anti-collision control unit is used to receive the real-time distance measured by the radar ranging system and calculate the real-time distance provided by the above-mentioned radar ranging system, and at ...

Embodiment 2

[0048] exist figure 2 In the shown embodiment 2, the vehicle longitudinal collision mitigation system is also provided with a tire burst monitoring unit, which is used to provide the tire burst data to the anti-collision control unit when a tire blowout accident occurs in the vehicle, and the rest is the same as in embodiment 1. .

[0049] The control method of the automobile longitudinal collision mitigation system of embodiment 2 is: when a puncture occurs in the car, 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, and the puncture The tire processing program detects the distance and relative speed between the vehicle and the rear vehicle and calculates the possible collision time. When the possible collision time between the vehicle and the rear vehicle is greater than 3 seconds, it sends out sound and light to the driver of the vehicl...

Embodiment 3

[0051] exist image 3 In the shown embodiment 3, the vehicle longitudinal collision mitigation system is also provided with a pre-tensioned safety belt control unit and an airbag control unit, wherein the pre-tensioned safety belt control unit is used to Tighten the seat belts to protect passengers during deceleration and braking; the airbag control unit is used to activate the airbags in advance to protect passengers according to the instructions of the anti-collision control unit, and the rest are the same as in embodiment 2.

[0052] The control method of the longitudinal collision mitigation system of the automobile in embodiment 3 is: when the possible collision time between the vehicle and the front vehicle or / and the rear vehicle is less than 2 seconds and greater than or equal to 1 second, the anti-collision control unit passes the pretensioned safety belt The control unit tightens the seat belts to protect passengers; when the possible collision time between the vehic...

Abstract

The invention discloses an automobile longitudinal collision mitigating system and a control method, which are used for avoiding automobile collision or lightening damages caused by the automobile collision to the utmost extent; the automobile longitudinal collision mitigating system comprises a front ranging radar and a rear ranging radar, a collision-prevention control unit, a speed control system and an alarming unit; the collision-prevention control unit is used for calculating relative speed of the automobile in relation with front and rear automobiles according to distance data provided by a radar ranging system, judging whether the collision occurs and the possible occurrence time of collision, sending corresponding instructions to actuating mechanisms according to preset programs, and controlling acceleration or deceleration braking of the automobile, so that the automobile collision is avoided or the damages resulting from the automobile 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 longitudinal collision mitigation system and control method which can avoid automobile longitudinal collision to the greatest extent or reduce automobile longitudinal collision damage. Background technique [0002] The anti-collision warning system is a hotspot in the current research of automobile safety assisted driving systems. It is generally divided into two systems for longitudinal collision and lateral anti-lane departure. Relative to the measurement and calculation of the position of the lane boundary line, but most of the existing anti-collision warning systems have considered the possible collision between the vehicle and the front vehicle. The issue of how to protect the passengers in the car is not enough, and the protection function is not complete. In recent years, with the successive maturity of ESC technology, pre-tensioned seat belt techn...
