Problems solved by technology

The unavoidable disadvantages of this solution are: (1) All sensors are connected to the signal processing integrated circuit board, and the types and quantities of sensors are numerous, which makes the signal processing integrated circuit board complicated, the circuit board design is difficult, wiring is difficult, and the cost is high

(2) The operating parts of the driving simulator are relatively scattered, such as the clutch pedal, brake pedal and accelerator pedal are generally located directly in front of the driving simulator operator, and the parking brake joystick and transmission joystick are generally located at the driving simulator operator. At the bottom right of the screen, operating components such as turn signals, far and near lights, and wipers are generally located directly in front of the driving simulator operator. The connecting wires of these operating parts must be connected to the signal processing integrated circuit board, making the connecting wires longer and easier to connect. many and messy

(3) Some of the existing steering wheel operating parts are also equipped with more operating parts, such as horn buttons, start buttons, light operation buttons, cruise control buttons, etc., and the connecting lines of these operating parts should also be connected to the signal When dealing with integrated circuit boards, these connecting lines are many and messy, and the steering wheel is required to be able to rotate within a certain angle (such as 540 degrees clockwise and 540 degrees counterclockwise from the center), so that the connecting lines of the operating components set on the steering wheel It also rotates with the steering wheel, so that the pins of the connecting wire are easy to loosen and the connecting wire is easy to break

(5) In the existing system, the keyboard or mouse is generally used as the operating device for the simulated driving software. For users who are not familiar with computer operation, it is difficult and the user experience is very poor; (6) The keyboard and mouse require a large (7) In some new multimedia devices such as Tmall's Magic Box, there is only one USB interface, except for connecting the signal processing integrated circuit board, there is no redundant USB interface that can be directly connected to the keyboard or mouse
