Vehicle in-the-loop test method and system

Abstract

The invention relates to a vehicle in-the-loop test method and system. The method comprises the steps that a real target vehicle obtains virtual vehicle data transmitted by a simulation platform in a current simulation period; the real target vehicle determines a front sensing target according to the received virtual vehicle data and performs vehicle control according to the determined front sensing target; the real target vehicle feeds back real vehicle control data synchronously generated in the vehicle control process to the simulation platform, so that the simulation platform updates a vehicle simulation model based on the real vehicle control data, and determines virtual vehicle data needing to be transmitted to the real target vehicle in the next simulation period based on the updated vehicle simulation model; and the next simulation period is entered, the step of acquiring the virtual vehicle data transmitted by the simulation platform in the current simulation period by the real target vehicle is returned, and operation is continously executed until the simulation platform determines that a preset simulation ending condition is reached, and a corresponding simulation test result is output by the simulation platform.

Description

technical field [0001] The present application relates to the technical field of intelligent driving, in particular to a vehicle-in-the-loop testing method and system. Background technique [0002] With the development of vehicle-road coordination technology, dynamic real-time information interaction between vehicles and roads can be realized through vehicle-road coordination technology, and effective collaboration and data sharing between different vehicles and roads can be realized. At present, quite a few algorithms need to be tested on real vehicles. At the same time, since actual vehicle parameters need to be used for calibration and strategy design in the software development process, testing on real vehicles has become an important part of the development process. However, due to the many external factors that need to be coordinated in the actual vehicle test, and the test needs in different test scenarios, different test environments and test conditions need to be pr...

Problems solved by technology

However, due to the many external factors that need to be coordinated in the actual vehicle test, and the test needs in different test scenarios, different test environments and test conditions need to be prepared during the test process, which requires a large amount of site and manpower. Resource overhead, there is a problem of low test efficiency
