Embodiment Construction

[0031] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0032] The invention relates to a method for preventing rear-end collisions of automobiles. The method is to install an early-warning device controller on the automobile, obtain the stepping depth of the brake pedal and the change rate of the pedal position through the early-warning device controller, and use it to identify whether a sudden braking state has been reached, and control the automobile. Hazard warning sound and light, to prevent rear-end collision warning; and through the early warning device controller to know the speed of the vehicle, the slope of the driving road, calculate the safety distance, and prevent rear-end collision by identifying whether there is a target vehicle in the lane within the safety distance. Vehi...

Abstract

The invention relates to an anti-tailgating method for vehicles and a pre-warning system. A pre-warning device controller is mounted on the vehicle, the tread depth and the position change rate of a brake pedal are obtained through the pre-warning device controller, so that whether the urgent brake state is reached is identified; and the acousto-optic warning for vehicle hazards is controlled to achieve the tailgating pre-warning. In addition, the driving speed of a self-vehicle and the gradient of a driving road are obtained by the pre-warning device controller to calculate the safety distance; and the pre-warning is started through detecting whether another vehicle enters the driving lane and whether the vehicle distance is shorter than the safety distance, and therefore the tailgating between the self-vehicle and a front vehicle is prevented. The pre-warning device controller receives signals output by a brake pedal position sensor, an inclination sensor, a self-vehicle speed obtaining module and a vision analysis module, and controls the acousto-optic warning for vehicle hazards, a driver of the self-vehicle is warned and drivers of the front vehicle and a rear vehicle are cautioned, and therefore the tailgating between two vehicles is prevented, and driving safety is increased.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an early warning device for preventing automobiles from being rear-end collided (front and rear collisions). Background technique [0002] As automobiles enter people's daily life in large numbers, automobile driving safety has received more and more attention and attention. As far as common car rear-end collisions or being rear-ended accidents are concerned, most of them are caused by the failure of the rear car to respond in time after the front car brakes suddenly, the safe distance between the self-car and the front car is not enough, or the purpose of the front car's brake is not clear (emergency brake or Lightly step on the brakes), resulting in insufficient braking force, failing to stop in time within a limited time and distance, resulting in a rear-end collision accident. In order to effectively avoid and reduce the occurrence of automobile rear-end collision ...
