Embodiment Construction
[0079] An embodiment of the present application provides a steer-by-wire system, which can be applied to smart cars, new energy vehicles, or self-driving cars, and these cars can be collectively referred to as vehicles. Among them, the steer-by-wire system is a system that controls the steering of the vehicle through electrical signals, canceling the mechanical connection device between the steering wheel and the steering wheel, so that the rotation between the steering wheel and the steering wheel is independent. This embodiment provides a steer-by-wire system that can control the range of rotation of the steering wheel, can also control the steering wheel to be consistent with the steering wheel, and can also control the automatic return of the steering wheel.
[0080] Such as figure 1 As shown, the steer-by-wire system includes a steering wheel 1, a steering column 2 and a limiting device 3, and the limiting device 3 includes a fixed rod 31, a slider 32 and a movable limiti...

The application discloses a steer-by-wire system and a steering control method, which belong to the technical field of vehicle steering and can be applied to smart cars, new energy cars or self-driving cars. The steer-by-wire system includes a steering column and a limit device, the limit device includes a fixed rod, a slider and a movable limit block; the slider is located on the fixed rod, and the slider can slide on the fixed rod as the steering column rotates; the movable The limit block is located on the fixed rod and can slide on the fixed rod, and is used to limit the slide block from sliding on the fixed rod, so as to realize the rotation of the steering column within the target rotation range. With this application, the limit device limits the steering of the steering column, so that the steering column no longer rotates unlimitedly, but rotates within the target rotation range corresponding to the rotation range of the steering wheel, so that the rotation of the steering column and the steering wheel The range is consistent, which is conducive to the driver's operation and control of the steering of the vehicle, and is conducive to driving safety.
Description
technical field [0001] The present application relates to the technical field of vehicle steering, in particular to a steering-by-wire steering system and a steering control method. Background technique [0002] The steer-by-wire system is a system that controls the steering of the vehicle through electrical signals, and cancels the mechanical connection between the steering wheel and the steering wheel. [0003] The steer-by-wire system mainly includes a steering controller, a steering drive motor, a steering wheel, and a steering column. The output shaft of the steering drive motor is connected to the steering wheel, and the steering wheel is installed at the end of the steering column. Sensors for rotation angle and torque. In this way, when the driver operates the steering wheel, the steering controller can obtain the angle and torque of the steering wheel through the sensor, and then control the steering drive motor to drive the steering wheel to turn according to the ...
