Abstract

The invention discloses a vehicle chassis test system and method based on intelligent driving and ADAS simulation, and the system comprises a scene interaction data preprocessing module which receives a control command that a test vehicle decision-making system controls a chassis execution system of a vehicle to make a motion response, and obtains the motion information of the test vehicle, carrying out fusion processing on the test vehicle motion information and a set scene to obtain relative motion target object motion information, and sending the relative motion target object motion information to a scene simulation device; the scene simulation device is used for carrying out real-time simulation control on a test scene according to the motion information of the relative motion target object; the road condition simulation control module is used for receiving the test vehicle motion information and the test requirement sent by the scene interaction data preprocessing module to form a road condition simulation control command; and the road condition simulation module executes corresponding road condition change according to the road condition simulation control command and is used for simulating the driving state of the test vehicle on the road.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle chassis testing system and method based on intelligent driving and ADAS simulation. Background technique [0002] In the process of vigorous development of the intelligent driving market at home and abroad, users' requirements for various performances of intelligent driving vehicles are increasing day by day, so they are paying more and more attention to reasonable and effective functions, performance testing methods and means of intelligent driving vehicles. In the process of vehicle research and development, a large number of tests and inspections must be carried out on vehicle parts and vehicles to obtain necessary data. The hub test is an important part of the vehicle test. Before a new vehicle is put on the market, it needs to complete a number of tests on the hub such as economy, power and driving range. [0003] The above-mentioned traditional vehicle hub test needs ...
