Intelligent driving vehicle obstacle avoidance system and method

Abstract

The invention discloses an intelligent driving vehicle obstacle avoidance system and method. The system comprises a sensing layer, a decision layer and an execution layer, wherein the sensing layer comprises a camera, a laser radar, an ultrasonic sensor, a millimeter wave radar and a GPS device which are mounted on a vehicle body; the decision layer mainly comprises an intelligent driving controller; the execution layer comprises an electronic resistance steering system, an electronically controlled braking system, turn signals and a horn of the vehicle; the input end of the intelligent driving controller is connected to the output ends of the camera, the laser radar, the ultrasonic sensor, the millimeter wave radar and the GPS device of the sensing layer; and the output end of the intelligent driving controller is connected with the controlled ends of the electronic resistance steering system, the electronically controlled braking system, the turn signals and the horn of the executionlayer. The intelligent driving vehicle obstacle avoidance system and method can enable an intelligent vehicle to realize obstacle avoidance, autonomous obstacle avoidance, and even autonomous obstacle avoidance in the whole road section, and improve the driving safety of the intelligent vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a vehicle obstacle avoidance system and method. Background technique [0002] With the development of artificial intelligence, more and more products are beginning to develop in the direction of networking, intelligence, and unmanned, especially in the automotive industry. Automobiles have been redefined as smart mobile terminals, shifting from mechanical products to electronic products. , including relevant national policies, that by 2020, the proportion of new smart cars in my country will reach 50%. Against such a strong background, intelligent driving vehicles and their related ecosystems have achieved unprecedented development, but unmanned vehicles cannot be achieved overnight. It requires continuous accumulation of technology, iterative and gradual development, and there are still many core technologies that need to be solved urgently. [0003] For intelligent d...

AI Technical Summary

Problems solved by technology

Lane keeping can basically realize vehicle tracking and achieve the purpose of intelligent driving, but if there is no good obstacle avoidance method when encountering obstacles, its practical application will be limited. Stop and wait, and should be able to change lanes autonomously and cross obstacles at the right time

The industry mostly uses the method of parking and waiting. At the same time, the vehicle is still in the closed road section test stage, and the problem of autonomous obstacle avoidance has not been considered.
