Motor control method and device of bistable gear shifter and automobile

A motor control device of a bistable gear shifter, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein when the processor executes the computer-readable instructions, the following steps are implemented:
• determine a current required gear according to a position of a shift lever and a gear judgment strategy;
• determine whether the current required gear is a P gear, an R gear or an N gear;
• further determine whether the shift lever is in a second steady state position, if it is determined that the current required gear is the P gear, the R gear or the N gear;
• determine whether a deviation of the position of the shift lever from the second steady state position is greater than or equal to a preset angle value, if it is determined that the shift lever is in the second steady state position;
• and
• determine a target angle of the motor as a target opening angle, if it is determined that the deviation of the position of the shift lever from the second steady state position is greater than or equal to the preset angle value.
