Abstract

The invention provides an automatic drive vehicle semi-physical simulation testing system and method; the system comprises a vehicle body, a fly wheel and a processing module; the vehicle body is fixed on an external lifting machine, and provided with tires that make contact with the flywheel; the vehicle body is used for driving the tires to rotate via an internal engine; the tires rotate to drive the flywheel to rotate; the processing module is used for determining rotation information of the flywheel; the method comprises the following steps: acquiring the vehicle body drive information; determining the vehicle body driving safety state according to the flywheel rotation information and the vehicle body drive information. The system and method need a small test field, and can better ensure the sensors on the automatic drive vehicle not to be damaged in a testing process, thus reducing the testing cost.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a semi-physical simulation test system and method for an automatic driving vehicle. Background technique [0002] With the development of science and technology, research on autonomous driving at home and abroad is gradually deepening, and people are paying more and more attention to the safety of autonomous vehicles, and performance testing is an important means to verify and improve the safety of autonomous vehicles. [0003] At present, the performance test of self-driving vehicles is generally carried out in a closed field, that is, by driving the self-driving vehicle in a closed field, collecting the driving parameters of the self-driving vehicle during the driving process, and then determining the driving safety state of the self-driving vehicle according to the driving parameters , to determine the safety performance of autonomous vehicles. [0004] This test method re...
