Problems solved by technology

However, increasing the internal friction of the steering gear will not only solve the steering wheel shimmy, but also increase the fuel consumption of the engine; and reducing the inner diameter of the steering gear oil pipe will cause problems such as poor steering return of the steering gear

Embodiment Construction

[0047] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] figure 1 It is a flowchart of a control method for a hydraulic steering gear provided according to an embodiment of the present invention. like figure 1 As shown, the present invention provides a control method for a hydraulic steering gear, the control method may include:

[0049] In step S110, the wheel speed is obtained. Wherein, the wheel speed can be obtained, for example, by communicating with the vehicle communication bus, and can also be obtained directly from a wheel speed sensor of the vehicle.

[0050] In step S120, it is determined whether high-frequency swivel occurs in the steering column. Specifically, the high-frequency rotation of th...

Abstract

The invention discloses a control method for a hydraulic steering gear, a controller and a vehicle. The control method includes the steps of obtaining the wheel rotating speed, determining whether high-frequency rotation happens to a steering pipe column or not, determining that a steering wheel vibrates when the obtained wheel rotating speed is larger than the preset wheel rotating speed threshold and it is determined that the high-frequency rotation happens to the steering pipe column, and reducing the flow of steering liquid flowing in the hydraulic steering gear when it is determined thatthe steering wheel vibrates. By means of the control method, the controller and the vehicle, the problems that the steering wheel vibrates, the comfort and operation convenience of a driver are influenced, and vehicle safety is endangered can be effectively solved, the oil consumption of an engine can not be increased, and energy conservation and emission reduction are facilitated.

Description

technical field [0001] The invention relates to the field of vehicle electronics, in particular to a control method for a hydraulic steering gear, a controller and a vehicle. Background technique [0002] With the continuous development of vehicle electronic technology, users have higher and higher requirements for the driving comfort, driving safety and operation convenience of the vehicle. The shimmy of the steering wheel is a common problem that affects these performances. The shimmy vibration of the steering wheel mainly occurs when the vehicle is running in a straight line at high speed. The wheels are affected by the dynamic imbalance and swing left and right. The wheels drive the steering rod to move axially through the steering knuckle, causing the steering column of the steering gear to rotate, and the steering wheel therefore Oscillation ensues, and once the oscillating frequency of the wheels matches the natural frequency of the steering wheel, the steering wheel ...
