Title:
MOTOR CONTROL METHOD AND DEVICE OF BISTABLE GEAR SHIFTER AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2021/244511
Kind Code:
A1
Abstract:
A motor control method of a bistable gear shifter. The method comprises: determining a currently required gear according to the position of a gear shift lever and a gear determination strategy; determining whether the currently required gear is a P gear, an R gear or an N gear; when it is determined that the currently required gear is the P gear, the R gear or the N gear, further determining whether a deflector rod is in a second stable state position or not; when it is determined that the deflector rod is in the second stable state position, determining whether the position of the deflector rod deviates from the second stable state position by being greater than or equal to a preset angle value; and when it is determined that the position of the deflector rod deviates from the second stable state position by being greater than or equal to the preset angle value, determining the target angle of a motor to be the target opening angle. This method solves the problem that an motor reset mechanism is jammed because a gear shift lever is quickly shifted to the M+ position or the M- position when an existing D gear is switched to an R gear or an N gear, and the problem that the gear shift lever is still in a second stable state while the automatic parking function intervenes and a D gear is required at the M/S gear. Further disclosed are a motor control device of the bistable gear shifter and an automobile comprising same.
