Abstract

The invention discloses an automobile intelligent braking system based on road surface visual detection and a control method thereof, belonging to the field of vehicle intelligent driving and braking safety control. Use the on-board camera to obtain high-definition images of the road the car is driving on, use the deep self-learning algorithm to determine the specific type of road the car is driving on, and determine the maximum braking deceleration of the car on the road; divide the maximum braking deceleration into several braking intervals , combined with the expected braking deceleration of the vehicle required by the upper control system to control the braking strength of the braking system; the braking system is a graded braking system based on floating caliper disc brakes, which can achieve the braking strength of the vehicle in grades, And can realize anti-lock function. The invention performs hierarchical control of the braking system according to the maximum braking deceleration and expected braking deceleration of the vehicle on the basis of determining the type of driving road surface, which not only ensures the safety and reliability of braking, but also greatly reduces the system cost.

Description

technical field [0001] The invention relates to an automobile intelligent braking system based on road surface visual detection and its control method, in particular to a system and method for controlling the braking intensity of the braking system according to the type of road surface on which the automobile is driving and the expected braking deceleration, and belongs to the vehicle Intelligent driving and braking safety control field. Background technique [0002] The vehicle braking system is the core and key to realize the deceleration and parking of the car, and to keep the speed of the car running downhill stable. It is very important to ensure the safety and reliability of the car. With the rapid development of society and economy, the number of automobiles continues to increase, and traffic accidents and traffic congestion have become one of the key problems that the government and related scientific research institutions need to solve urgently. Through the compreh...
