Problems solved by technology
However, there is a certain deviation between the position of the steering column detected by this method and its actual position, which makes the detection result of the position of the conversion column inaccurate. As the deviation accumulates, the adjustment of the position of the steering column will eventually become invalid.

The invention relates to a position detection method and device of a steering pipe column, a storage medium and a vehicle. The position detection method of the steering pipe column comprises the stepsthat a position adjustment instruction for the steering pipe column is received, and the position adjustment instruction comprises a target rotation direction of a motor of the steering pipe column;when the target rotation direction is consistent with a preset direction, the first edge of a pulse signal triggered during motor rotation is counted; when the target rotation direction is opposite tothe preset direction, the second edge of the pulse signal triggered during the motor rotation is counted, if the first edge is a rising edge, the second edge is a falling edge, and if the first edgeis a falling edge, the second edge is a rising edge; the current cumulative number of rotation of a motor is determined according to a count value; and according to the current cumulative number of rotation, a current position of the steering pipe column is determined. Through the technical scheme of the position detection method of the steering pipe column, count deviation of the pulse signal canbe eliminated, and the position detection accuracy of the steering pipe column can be improved.
Description
technical field [0001] The present disclosure relates to the field of vehicles, in particular, to a method, device, storage medium and vehicle for detecting the position 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 steering column (that is, the position of the actuator), the position adjustment of the steering column can be realized, and then the steering wheel and other mechanisms can be adjusted to meet the needs of the driver and passengers. need. [0003] The position detection method of the steering column in the prior art usually counts the pulse signals triggered during the rotation of the motor, and determines the accumulated rotation number of the motor according to the count value of the...
