Automotive braking automatic auxiliary system and control method thereof

Abstract

The invention discloses an automotive braking automatic auxiliary system and a control method thereof. The automotive braking automatic auxiliary system comprises a power supply module and an electronic controller; the electronic controller is connected with a road surface selecting unit, a speed monitoring device, a road surface humidity sensor, a distance measuring sensor, an alarm module and a brake parachute system; the power supply module provides power for the electronic controller and the brake parachute system. The control method includes that the safe driving distance is calculated out through the electronic controller according to the current speed and the road surface driving environment; the relation between the current actual distance and the safe distance is measured out through the distance measuring sensor; an appropriate control instruction is given out through the electronic controller according to the relation between the current actual distance and the safe distance. According to the automotive braking automatic auxiliary system and the control method thereof, real-time all-around monitoring can be performed on the driving environment, the driving pressure of drivers can be reduced, and the safe driving under different environmental road surfaces can be ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an automatic brake assist system for an automobile and a control method for the system. Background technique [0002] Inattention of the driver caused by fatigue, drugs or other reasons, as well as the influence of weather and other factors can easily cause the driver to misjudge the distance between vehicles, pedestrians or other obstacles in front, resulting in insufficient braking distance of the car and causing traffic accidents. ACCIDENT. In addition, under different road conditions and different vehicle speeds, the braking distance of the car is also different. Now drivers can only judge whether the braking distance is sufficient based on their own experience, which is also one of the reasons for traffic accidents. [0003] At present, the main braking force of automobiles comes from the friction between the wheels and the road surface. In order to increase the brak...

Problems solved by technology

However, there are still some deficiencies in the present technology, for example: 1. The driver needs to manually open the deceleration parachute, which will increase the driver's operation, make it distracted, and cause traffic accidents more easily; 2. In an environment with low visibility, driving The driver cannot accurately judge the distance, and cannot open the deceleration parachute in time; 3. Although some technologies use computers to automatically control the deceleration parachute to open, they do not have the ability to distinguish road conditions, so that the deceleration parachute is opened too late or wrongly opened, resulting in accidents
