Problems solved by technology

[0004]However, although the existing technology can adopt different steering commands in different working modes, while ensuring the normal energy consumption of the vehicle, it is better to realize the steering control of the vehicle However, due to the introduction of a new equipment axial encoder in the existing technology, the hardware cost of the whole vehicle is increased. At the same time, once the axial encoder fails, the vehicle can hardly run normally, increasing the after-sales cost

Abstract

The embodiment of the invention discloses a steering control method, device and equipment and a storage medium. The method comprises the steps of when a power-assisted steering signal is detected to be activated, sending a steering instruction to a pump motor of a vehicle so that the pump motor is controlled to be in a steering rotating speed mode; judging whether the vehicle meets a power-assisted steering condition or not; and according to the judgment result, enabling the pump motor to be in a corresponding working mode, wherein the working mode is the steering rotation speed mode or the idling rotation speed mode. By means of the technical scheme, the power-assisted steering process is optimized, and ideal power-assisted steering is provided for a driver under the condition that no extra hardware cost is introduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of control, and in particular, to a steering control method, device, device, and storage medium. Background technique [0002] Due to the weight of the whole vehicle, the forklift must provide steering assistance for the driver to turn the steering wheel when turning. Among them, a higher motor speed will produce more ideal steering assistance, assisting the driver to complete the steering of the vehicle more easily. Usually, power steering includes two working modes: idle speed mode and steering speed mode. In the idle speed mode, the pump motor will give a lower speed to reduce system energy consumption; in the steering speed mode, the pump motor will give A relatively high speed assists the driver to complete the steering wheel steering operation. [0003] At present, the existing technology is mainly through adding an axial encoder on the steering wheel. When the vehicle has...
