Intelligent automobile braking system based on road surface visual inspection and control method thereof

Abstract

The invention discloses an intelligent automobile braking system based on road surface visual inspection and a control method thereof, and belongs to the field of intelligent vehicle driving and braking safety control. The control method comprises the steps that an in-vehicle camera is used for obtaining a high-definition image of a road surface on which an automobile is running, a deep self-learning algorithm is used for determining the specific type of the road surface on which the automobile is running, and the maximum braking deceleration of the automobile on the road surface is determined; the maximum braking deceleration is divided into a plurality of braking intervals, and the multiple braking intervals are combined with the expected braking deceleration realized by the automobile and required by an upper control system to control the braking strength of the braking system; and the braking system is a grading braking system based on a floating caliper disc type brake, can achieve the braking strength of the automobile in a grading mode, and can achieve an anti-lock function. According to the intelligent automobile braking system based on road surface visual inspection and the control method thereof, grading control over the braking system is performed according to the maximum braking deceleration and the expected braking deceleration of the automobile based on the determination of the driving road surface type, so that the braking safety and reliability are ensured, and the system cost is greatly reduced.

Description
