Abstract

The invention discloses a steering wheel force feedback system stimulating real force feeling. The steering wheel force feedback system includes a PC machine, a motor, a motor driver, a moment sensor, an angle sensor, and a controller, the controller and the PC machine are in data exchange via a USB protocol, the controller reads the moment data of the moment sensor and the angle data of the angle sensor and transmits the moment data and the angle data to the PC machine via a USB, the PC machine calculates control signals by means of a moment curvilinear equation based on the moment data and the angle data, the control signals are transmitted to the controller via the USB, and the controller controls the running of the motor by means of the calculated control signals. The system transmits data by means of the USB protocol data transmission manner which is fast in data transmission speed and is compatible with the sampling time of a simulation system; and the system reduces the data interfaces of the simulation system, effectively improves the simulation efficiency, so that the high-speed real-time simulation timeliness is good and the accuracy of algorithm verification can be guaranteed.

Description

technical field [0001] The invention relates to the field of car driving simulators that can be used for car research and development personnel to verify algorithms or other forms, especially the field of force-sensing interactive car driving simulators with force-feedback. Background technique [0002] With the development of automobile technology, the active safety technology of automobiles has attracted more and more attention from the world, which requires the further development of safer and more practical algorithms. The traditional method for developers to verify algorithms is to use real cars, but this method has disadvantages such as unsafe, high cost, and low efficiency. The car driving simulator can effectively overcome these shortcomings, so using a car driving simulator to help developers verify algorithms has become the first choice for the automotive industry. [0003] Simulation software such as Matlab / Simulink is often used in the process of verifying algor...
