Embodiment Construction

[0038] Specific embodiments of the present disclosure 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 disclosure, and are not intended to limit the present disclosure.

[0039] It should be noted that the terms "first" and "second" in the specification and claims of the present disclosure and the above drawings are used to distinguish similar objects, and do not necessarily have to be interpreted as a specific sequence or sequence.

[0040] In order to make it easier for those skilled in the art to understand the improvements made by the embodiments of the present disclosure over the prior art, a brief introduction to the position offset occurring during the adjustment of the steering column is firstly made.

[0041] like figure 1 As shown, the actuator of the steering column has a fixed maximum stroke. When the motor rotate...

Abstract

The present disclosure relates to a method, a device, a storage medium and a vehicle for correcting the position offset of a steering column. Record the amount of change in the number of rotations of the motor relative to the number of rotations at zero point. The number of rotations at zero point is the predetermined number of rotations when the motor rotates in the preset direction until it reaches the locked-rotor state. The amount of change is used to determine the adjustment of the steering column Position; when the variation is zero and the motor has not reached the locked-rotor state, control the motor to rotate in the preset direction until it reaches the locked-rotor state, and use the number of rotations of the motor when it reaches the locked-rotor state as the new zero-point rotation number . Through the technical solution of the present disclosure, the deviation between the actually detected position of the steering column and its actual position can be corrected, thereby improving the position adjustment accuracy of the steering column, and avoiding adjustment failures caused by position deviation, so that the steering column The adjustment process of the column is more stable and reliable.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a method, device, storage medium and vehicle for correcting a position offset of a steering column. Background technique [0002] The steering column is an important component of the vehicle, which includes the actuator connected to the steering wheel of the vehicle and the motor used to drive the actuator to move. By driving the motor of the steering column to rotate and detecting the position of the actuator, the position adjustment of the steering column can be realized, and then the adjustment of the steering wheel and other mechanisms can be realized to meet the needs of the driver and passengers. [0003] However, due to the mechanical clearance of the actuator, there is a certain deviation between the detected adjustment position of the actuator and its actual position. The position of the column is not adjusted correctly. Contents of the invention [00...
