Chinese patent CN102530050A discloses a joystick device that integrates steering, braking, and gear shifting based on an automobile control-by-wire system. The structure of the device is simple, but it does not take into account the suspension by wire and the fault-tolerant mechanism, nor does it have the function of automatic steering correction , poor anti-interference ability; Chinese patent CN102582674B discloses a two-degree-of-freedom force output joystick that can control vehicle acceleration, steering, and braking. The fault-tolerant mechanism and the function of automatic steering return are not suitable for the control-by-wire chassis vehicles that have extremely high safety requirements

The invention designs a joystick mechanism and a joystick control system based on a wire-controlled chassis, belonging to the field of wire-controlled automobiles. Through the combined use of permanent magnets and variable damping fluid, the joystick mechanism realizes the automatic return function of the vehicle and improves the ability of the vehicle to resist road interference; by manipulating different buttons, the vehicle gear can be switched; turning the joystick The ratchet wheel on the top can realize the adjustment of the suspension and improve the passability and comfort of the car. The joystick control system includes two joystick mechanisms designed by the present invention, different control modes and a set of fault-tolerant mechanism. Through the cooperative use of the two joysticks, the vehicle can be driven obliquely in any direction and rotate around its geometric center. Improve the maneuverability of the vehicle; through the selection of different modes, the joystick designed by the present invention can be applied to different chassis structures and different types of drivers, which improves the applicability of the joystick; through the design of the fault-tolerant mechanism, the vehicle driving safety.
Description
technical field [0001] The invention belongs to the field of wire-controlled automobiles, and in particular relates to a joystick mechanism and a joystick control system based on a wire-controlled chassis. The joystick mechanism based on the control-by-wire chassis designed in the present invention integrates steering, braking, driving, and suspension, and has the function of automatically returning to the center of the steering and its centering torque is adjustable, which improves the ability of the automobile to resist road interference; The lever mechanism is not only suitable for different control-by-wire chassis structures such as front-wheel steering to rear-wheel drive, front-wheel steering to front-wheel drive, front-wheel steering to four-wheel drive, four-wheel steering to rear-wheel drive, and four-wheel independent steering to four-wheel independent drive. It is suitable for people with different physical fitness and driving habits, which improves the applicabilit...
