Abstract

The invention provides a vehicle verification platform with adjustable control characteristics, and the platform comprises a data collection system which is used for collecting the control parametersof a power system of a variable stability vehicle and the first motion state of the variable stability vehicle in six degrees of freedom, and taking the control parameters and the first motion state as input data; a numerical simulation system which is used for analyzing a second motion state of the variable stability vehicle in six degrees of freedom based on the input data and taking the secondmotion state as control input; an intelligent control system which is used for calculating the optimal control scheme of the variable stability vehicle in the current state according to the control input and converting the optimal control scheme into a corresponding output signal; and a power system which is used for outputting output parameters to the data acquisition system and the intelligent control system according to the output signals, and is also used for performing comparative analysis on the input data and the second motion state to correct the output parameters of the power system.A variable-stability vehicle for simulating the driving state of a target vehicle with dynamic characteristics is used as a verification platform of an automatic driving program to verify the controlability of the automatic driving program on different vehicles.

Description

technical field

[0001] The invention relates to the technical field of vehicle automatic driving control and simulation, in particular to a vehicle verification platform with adjustable handling characteristics and an implementation method. Background technique

[0002] In the era of autonomous driving, the driving of vehicles will gradually be completed by artificial intelligence programs. How to evaluate the ability of artificial intelligence programs to control different vehicles has become a core problem. One of the main hurdles is that there are huge differences in the scale, dynamic characteristics, etc. of different vehicles. It is difficult to prove that an artificial intelligence program with autonomous driving capabilities on a certain vehicle is equally effective on other vehicles. In the future, it will be very dangerous to directly let an unverified artificial intelligence program operate different vehicles, and it will be expensive to repeatedly build different...
