Simulation testing platform system for researching driving behaviors

Abstract

The invention relates to a simulation test platform system for researching driving behaviors, which can provide a vehicle environment and driving functions which are completely consistent with the actual driving for drivers, ensures the driving operation and the authenticity of vehicle data acquisition, and ensures the basic simulation of the indoor use of a test vehicle and the feedback of road conditions to the driving so as to provide a traffic visual simulation environment with high immersion for the drivers. The simulation test platform system comprises a driving test vehicle, a driver information acquisition system, a vehicle information acquisition and processing system, a traffic simulation visual driving module, a visual projection system, a visual simulation and a road traffic scene modeling system, a road driving resistance simulation system and a system integration module, wherein the driving test vehicle is connected with the vehicle information acquisition and processingsystem, and the real-time communication exchange and data feedback between the vehicle information acquisition and processing system and the traffic simulation visual driving module are carried out through the system integration module. The simulation test platform system is characterized in that the driving test vehicle is of a real mini bus, and the steering mechanism of the mini bus is disconnected.

Problems solved by technology

Developed countries such as Japan have done a lot of research work in this area, and have developed corresponding driving simulators for driving training tests and development-type car simulators for research. The driving seat, steering wheel, gears, brakes and other mechanical parts close to the car, or the frame of the whole vehicle that removes the engine power, movement device, electronic control and other systems, the vehicle power is replaced by the motor, etc., the disadvantage is that although it Sensors are used to collect information on driver operations such as steering wheel, brakes, accelerator, gears, etc., but because the vehicle engine power and electronic control system have been removed or motors have been used to replace power, the corresponding devices (steering wheel, brakes, accelerator, gears, etc.) The operating experience is very different from that of the real vehicle; it uses the vehicle simulation dynamics model to simulate and output the steering, speed, acceleration and other motion information of each degree of freedom of the vehicle, which cannot fully ensure that the driving operation and vehicle motion information are consistent with the actual situation; in addition, previous simulations The simulation device has no wheels or the driving wheels cannot rotate. The road condition simulation mainly calculates the driving resistance of the vehicle based on the road surface friction coefficient, slope, etc., and feeds back to the vehicle simulation dynamics model to calculate and output the vehicle motion information. The driver is stepping on the accelerator and other operations. The reaction is to feel and adjust the operation through the state changes such as the running speed of the simulation scene, which is quite different from the real road driving; in addition, the simulation display of the road traffic scene mainly uses single / three display screens or projection systems with less than three channels Since the coverage angle of the visual simulation scene is within 120 degrees, when the driver turns left or right, he can see other non-simulated traffic scenes and other objects, which will interfere with the driver's concentration on driving
