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] Such as figure 1 As shown, the actuator of the steering column has a fixed maximum stroke. When the motor rot...

Abstract

The invention relates to a method and device for correcting a position deviation of a steering column, a storage medium and a vehicle. The method includes the steps that in the adjustment process of the steering column, based on the number of turns of rotation at zero of the steering column, the change amount of the number of turns of rotation of a motor relative to the number of turns of rotationat zero is recorded in real time, the number of turns of rotation at zero is the predetermined number of turns of rotation when the motor rotates in a preset direction until the motor reaches a locked-rotor state, the change amount is used for determining the adjustment position of the steering column; and when the change amount is zero and the motor does not reach the locked-rotor state, the motor is controlled to rotate in a preset direction until the motor reaches the locked-rotor state, and the number of turns of rotation when the motor reaches the locked-rotor state is used as new numberof turns of rotation at zero. According to the technical scheme, the deviation between the actually detected steering column position and the actual position of the steering column can be corrected,the position adjustment accuracy of the steering column is improved, the adjustment failure caused by the position deviation is avoided, so that the adjustment process of the steering 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...
