A New Generation of Virtual Driving Simulation Platform

Overview
With the improvement of the functions of the intelligent driving system, there are more and more interactive functions between the driver and the intelligent driving system, and the complexity of the test is getting higher and higher. HiRain Technologies’s newly launched virtual driving simulation platform can provide realistic virtual driving scenes, real cockpit environment, and dynamic driving experience in a laboratory environment, it can achieve a highly immersive driving experience and satisfy interaction function test requirements between driver behavior and intelligence driving system.

• The virtual driving simulation platform supports co-simulation with the unmanned simulation test system to test the influence of driver behavior intervention on the driverless function or subjective evaluation of the control effect of the driverless vehicle
• The virtual driving simulation platform can be associated with traffic participants to realize the game between human drivers and the unmanned driving system (for example, when a human is driving on and off the ramp  that jumps in line and interact with the unmanned driving system), resulting in a more realistic Traffic disturbance
• Provides an extensible human factor efficacy evaluation system in unmanned driving, which is used to analyze human physiological characteristics and behavioral responses in unmanned vehicles, and evaluate the impact of unmanned driving systems on occupants
• The virtual driving simulation cockpit can be modified based on the real car to achieve a realistic experience environment, and it can also be developed based on user needs to customize the shape to meet the needs of different users
• Provide a six-degree-of-freedom motion platform, and cooperate with the wash-out algorithm to simulate the body feel of a real car, so that the driver has a more realistic sense of immersion
• Provide realistic pedal feel simulation and steering wheel feel simulation
