specific Embodiment
[0035] The virtual simulation subsystem of the driving environment is composed of an industrial computer, a display screen 7 and an intelligent network simulation software. As a hardware carrier, the industrial computer can run the intelligent network simulation software. In the simulation software, the starting point, the ending point and the driving route of the current trip are set based on the map database. At the same time, the traffic flow density, traffic light timing and other traffic flow in the driving route information to set. After the test starts, the display screen 7 updates and displays the driving environment information in real time according to the driving situation of the vehicle, and presents it to the driver of the test vehicle. The driver manipulates the accelerator pedal and the brake pedal according to the driving environment shown on the display screen 7 and his own driving experience, so as to control the driving speed of the vehicle. Since the vehic...
