Anti-collision early warning device based on active safety of vehicle and method

Abstract

The invention discloses an anti-collision early warning device based on active safety of a vehicle. The device comprises a distance measuring device, a corner sensor, a controller and a reminding device, wherein the distance measuring device is arranged on the front part of the vehicle and is used for monitoring a distance between the vehicle body and the front vehicle in real time; the corner sensor is connected with a rotating shaft part of a steering column of a steering wheel through a belt and is used for monitoring the corner information of the steering wheel; the controller is connected with the distance measuring device and the corner sensor and is used for receiving the distance information and the corner information of the steering wheel and judging the risk of the vehicle state; the reminding device is connected with the controller and is used for reminding the driver of danger. The invention also discloses an anti-collision early warning method based on the active safety of the vehicle.

Description

technical field [0001] The invention relates to the field of active safety of traffic systems, in particular to an anti-collision early warning device and method based on vehicle active safety. Background technique [0002] Rear-end collision refers to the behavior of the front of the rear vehicle colliding with the rear of the vehicle in front when vehicles traveling in the same lane are following behind, mainly due to the following distance being less than the minimum safety distance and the slow response of the driver or the poor performance of the braking system. Under any circumstances, it is required to keep a certain safe distance between the two vehicles. Without the distance, the driver will lose the time to react, and no matter how good the vehicle brake is, it will lose the stage to play its role. In order to prevent rear-end collision accidents, keep a corresponding The safe distance is very important; however, in the process of high-speed driving, it is impossib...

[0002] Rear-end collision refers to the behavior of the front of the rear vehicle colliding with the rear of the vehicle in front when vehicles traveling in the same lane are following behind, mainly due to the following distance being less than the minimum safety distance and the slow response of the driver or the poor performance of the braking system. Under any circumstances, it is required to keep a certain safe distance between the two vehicles. Without the distance, the driver will lose the time to react, and no matter how good the vehicle brake is, it will lose the stage to play its role. In order to prevent rear-end collision accidents, keep a corresponding The safe distance is very important; however, in the process of high-speed driving, it is impossible to predict in advance the situation that the car and the dangerous vehicle in the non-own lane merge into or suddenly break into the lane, or for the In the urban road driving environment, dense and interweaving traffic and frequent lane changes will lead to frequent rear-end collision accidents, and most of the estimation of the safety distance is only for the vehicle ahead in the lane, which also leads to the There are frequent friction accidents with vehicles in non-own lanes. Therefore, it is particularly important to provide comprehensive anti-collision warnings for vehicles in front of the own lane and non-own lanes.
