Steering collision avoidance method and system for truck with trailer

Abstract

The present application provides a steering avoidance method and system for a trailer truck. The method includes: during the steering process of the trailer truck, determining the dangerous area according to the angle between the tractor and the trailer of the trailer truck, and The location in the area determines the collision avoidance strategy; during the execution of the collision avoidance strategy, if the driver’s manual collision avoidance operation is detected, the manual collision avoidance operation is used to control the trailer truck; Under the control of the collision operation, judge the change of the collision risk according to the position of the obstacle in the dangerous area; if the collision risk is not eliminated, use the A collision avoidance strategy replaces the manual collision avoidance operation to control the trailer. In this embodiment, the risks in the steering process are accurately evaluated to effectively avoid collisions.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicle control, and in particular, to a method and system for steering and avoiding collisions of a truck with a trailer. Background technique [0002] Among the traffic accidents related to trucks with trailers (tractors + trailers), a large proportion of traffic accidents occur in the scene of trucks turning right, and the injuries caused by accidents in this scene are more serious. The main reasons include: 1. When a truck with a trailer turns right, vulnerable traffic participants such as pedestrians and non-motor vehicles make the entire right-turn traffic scene more complicated. 2. When a truck with a trailer turns right, there is a large blind area of ​​vision, and it is easy to collide with pedestrians and non-motor vehicles in the scene of right turn. [0003] At present, trucks with trailers rely solely on blind spot detection and early warning, and have limited col...

AI Technical Summary

Problems solved by technology

[0002] Among the traffic accidents related to trucks with trailers (tractors + trailers), traffic accidents occurred in the right turn scene of the truck accounted for a large proportion, and the accidents caused serious injuries in this scene. The main reasons include: 1. When turning right with a trailer, vulnerable traffic participants such as pedestrians and non-motor vehicles make the entire right-turn traffic scene more complicated

2. There is a large range of blind spots when a truck with a trailer turns right, and it is easy to collide with pedestrians and bicycles in the right turn scene

[0003] At present, trucks with trailers rely solely on blind spot detection and early warning, and have limited collision avoidance capabilities for the complex scene of turning right.
