An Intelligent Vehicle Obstacle Avoidance System Based on Predictive Safety

Abstract

The invention discloses an intelligent vehicle obstacle avoidance system based on safety prediction. The intelligent vehicle obstacle avoidance system based on the safety prediction comprises a vehicle-mounted control module, a travelable area predicating module, a steering angle control module, a speed control module, a vehicle-mounted GPS module, a vehicle-mounted speed measuring module, a laneline identification module, an obstacle vehicle tail lamp recognition module and a radar module; the travelable area predicating module receives road information, obstacle vehicle tail lamp information, obstacle vehicle speed information, obstacle vehicle traveling direction information and obstacle vehicle position information, predicates an obstacle vehicle traveling intention according to the information, combines the obstacle vehicle traveling intention with the road information to calculate a dynamic travelable area within a period of time, and transmits the dynamic travelable area withinthe period of time to the vehicle-mounted control module; and the vehicle-mounted control module calculates steering angle control quantity and speed control quantity of the traveling within the dynamic travelable area and transmits the steering angle control quantity and the speed control quantity of the traveling to the steering angle executing module and the speed control module.

Description

technical field [0001] The present invention relates to an intelligent vehicle obstacle avoidance system, and more specifically, relates to an intelligent vehicle obstacle avoidance system that determines a feasible area by predicting the motion posture of an obstacle vehicle. Background technique [0002] With the increasing number of cars, road traffic tends to be denser and more complicated, which leads to an increase in driving pressure, which reduces the driving ability of drivers in normal traffic scenarios and greatly increases the probability of traffic accidents. Smart vehicles can autonomously avoid obstacles and avoid risks through advanced technology, which has become a key research direction to solve vehicle safety. [0003] An intelligent vehicle obstacle avoidance system usually consists of a self-vehicle state perception module, an environment perception module, a vehicle control module, and an execution module. The on-vehicle control module receives vehicle...

Problems solved by technology

[0004] However, the obstacle avoidance of intelligent vehicles is a dynamic process, and the obstacle vehicles in the actual scene are not stationary

The above methods can only consider the current position of the obstacle vehicle, and cannot predict the driving intention of the obstacle vehicle, which is prone to problems such as insufficient road utilization or reduced vehicle safety.
