Intelligent Driving Simulation Test Solution

Overview
Simulation test verification, as a very important procedure in the development process of intelligent driving system, can solve the problems of low efficiency of real vehicle test, high risk of some working conditions, high cost of real vehicle test, and unreproducible working conditions during the test process of intelligent driving system. The intelligent driving concept covers the traditional advanced driving assistance system (ADAS) and fully automatic driving system (AD). Generally, it includes three parts: environment perception, intelligent decision-making, and vehicle control. The new generation of intelligent driving HIL simulation test platform launched by HiRain Technologies can provide realistic road traffic scenes, high-precision vehicle dynamics model and various types of sensor simulation, which can meet the simulation test requirements of intelligent driving system from L1 to L5. Users can establish various of intelligent driving test scenarios on this platform to run adequate and efficient tests on perception, decision-making, and vehicle control.
