Problems solved by technology

[0003] At present, the main measure for the development and verification of the lane keeping system is the real vehicle road test. There are many problems in the real vehicle road test: the real vehicle test method greatly prolongs the development cycle of the controller and increases the development cost; The randomness of the road scene is strong, and it is impossible to accurately verify the characteristics of the controller; the real vehicle test is highly dangerous, and the test cannot be carried out under various extreme conditions

Abstract

The invention provides an automobile lane-keeping strategy verification platform. The automobile lane-keeping strategy verification platform comprises a hardware system, an upper computer, a control software, a lane-keeping controller and a lane-keeping simulation bench, wherein the lane-keeping controller is arranged on the lane-keeping simulation bench, the upper computer and the control software are used for setting different road scenes and environment scenes, testing required parameters and generating a model required for testing, and the lane-keeping controller acquires a control parameter set by a tester and feeds back a control result to the upper computer through the hardware system. The automobile lane-keeping strategy verification platform has the advantages that the effectiveness of the lane-keeping controller is verified by adopting the simulation of a whole vehicle driving environment, compared with real vehicle verification, the verification cost and the development cycle can be shortened; test scenes can be set arbitrarily, the test verification is more comprehensive, the repetitive recurrence verification of a specific scene can be achieved, and the safety problemsof real vehicle testing under high vehicle speed, sharp curve and lane departure testing are solved.

Description

technical field [0001] The invention belongs to the field of development of an advanced auxiliary driving system for automobiles, in particular to the development of a vehicle lane keeping control strategy verification platform. Background technique [0002] ADAS (Advanced Driver Assistance System) is at the forefront of the current development of automotive technology, and it is also a bridge for the accumulation of unmanned driving technology. Its principle is to collect road and environmental information around the vehicle through radar, camera and other sensors to provide drivers with safer decisions. mechanism to ensure the safety of the driver. As one of the core technologies of ADAS, the lane keeping system collects lane lines through the camera and calculates the distance between the vehicle and the left and right lane lines in real time, automatically controls the vehicle steering system and assists the driver to keep the vehicle in its own lane, which can greatly r...
