The invention discloses an instrument panel pointer control method, and belongs to the technical field of instrument panels, an instrument panel comprises a pointer, a motor and a controller, the motor is used for driving the pointer to rotate, and a limiting check block is arranged at the zero position of the motor. The rotor reversely accelerates to reach the first angular speed and then impacts the limiting stop block at the first angular speed; and the rotor rebounds after impacting the limiting check block, and the controller controls the rotor to repeatedly impact the limiting check block at the reset angular velocity until the limiting check block stops, so that the pointer returns and stops at the zero point position. The motor is controlled to be reversely accelerated to a high speed, so that the rotor has a small torque when impacting the limiting stop block, springback and noise generated by impacting the limiting stop block are reduced, after zero-returning self-inspection of the motor is completed, the pointer of the instrument panel can indicate the zero point, the position of the pointer after zero returning serves as a reference point of rotation, and inaccurate indication of the pointer is avoided.
本发明公开了一种仪表盘指针控制方法,属于仪表盘技术领域,该仪表盘指针控制方法,仪表盘包括指针、电机及控制器,电机用于驱动指针转动,电机的零位处设有一限位挡块,控制方法包括:控制器控制电机的转子反向转动,转子反向加速达到第一角速度,后以第一角速度撞击限位挡块;转子撞击限位挡块后回弹,控制器控制转子以复位角速度反复撞击限位挡块直至停止,以使指针回归停止在零点位置。通过控制电机反向加速至较大速度,以使转子撞击限位挡块时具有较小的力矩,从而使减小撞击限位挡块产生的回弹和噪声,并且电机归零自检完成后,仪表盘指针会指示在零点,以归零后的指针位置为旋转的基准点,避免指针指示不准。
