The invention discloses a driving simulator high-simulation tactile feedback system for man-machine co-driving evaluation, and belongs to the field of driving simulators. Comprising an electronic brake pedal, an electronic accelerator pedal, a force feedback steering wheel and a microcontroller. The force feedback steering wheel comprises a steering wheel body, a steering shaft, a turbine, a worm, a steering column, a fixed supporting structure, a direct-current power-assisted motor, an electromagnetic clutch and a magnetic ring encoder. A steering wheel, an accelerator and a brake are subjected to fusion control, the steering torque of the steering wheel is controlled according to the brake and accelerator stepping force of a driver, and cooperative control of a complete tactile sensing system is achieved; in the aspect of force feedback simulation, an electromagnetic clutch is additionally arranged between a direct-current power-assisted motor and a steering shaft of a steering wheel, the direct-current power-assisted motor is used for controlling the rotating speed and the direction, the electromagnetic clutch provides damping of force feedback, force feedback or automatic return of the steering wheel is achieved, and a driver obtains real road feeling.

Description

technical field [0001] The invention belongs to the field of driving simulators, and in particular relates to a high-fidelity haptic feedback system for driving simulators for human-machine co-driving evaluation. Background technique [0002] With the continuous development of human-machine co-driving technology, driving simulators are more and more widely used in scientific research and industry. High-fidelity driving simulators can test the functional characteristics of the man-machine co-pilot system and verify the takeover characteristics of the man-machine co-pilot system, which has an important impact on the construction of the man-machine co-pilot evaluation system. [0003] Driving simulators are mainly divided into static simulators and dynamic simulators. In a static simulator, the visual and auditory systems are responsible for participating in motion perception. In a dynamic simulator, other sensory systems of the body are also involved in constructing the driv...

AI Technical Summary

Problems solved by technology

[0004] At present, the customized high-end driving simulator system is expensive, it is developed for specific scenarios, and it is difficult to realize other functions, and the high-end simulator is generally limited by foreign technology, the system is highly integrated, and the development is difficult

The traditional common driving simulator system generally controls the steering wheel, accelerator, brake and other components independently, and does not realize a complete set of systems for coordinated control, and only relies on the DC motor to complete the force feedback control, which will cause the steering wheel force feedback to be distorted and reduce the Immersion in a Driving Simulator
