Description

technical field [0001] The invention relates to the field of computer simulation, in particular to an intelligent vehicle simulation method and device. Background technique [0002] A smart car is a car that senses the road environment through an on-board sensor system, automatically plans a driving route, and controls the vehicle to reach a predetermined target. In the research and development process of smart cars, a large number of experiments are often required to test the functions of smart cars. Compared with the real vehicle road test, the test method using computer simulation can effectively shorten the development cycle and reduce the development cost. The traditional computer simulation test method is to carry out numerical simulation with the help of tools such as Matlab and Simulink, input vehicle parameters, road conditions and other environmental parameters, and the test results are expressed in the form of parameter curves. [0003] This numerical simulation...
