The invention relates to an acceleration and deceleration driving method for a stepping motor. The acceleration and deceleration driving method for the stepping motor comprises the following steps: presetting a stepping time interval data sheet; acquiring rotating speed data information; updating target rotating speed data according to the rotating speed data information; and drying the stepping motor according to the target rotating speed data. In the process of the driving the stepping motor according to the target rotating speed data, the stepping motor is driven by the corresponding driving strategy according to the stepping interval of from the current position to the target driving position. The invention adopts the driving strategy of combining sectional drive and other driving modes, so that the problem that a tachometer of an automobile instrument needs to quickly respond to the change of the automobile rotating speed can be solved, a pointer of the stepping motor can have high response speed and the whole smooth operation effect can be achieved no matter the change amplitude of the rotating speed is small or large, shaking is avoided, the visual effect is the best and the user experience is enhanced.
Description
technical field [0001] The invention relates to a motor driving method, in particular to an acceleration and deceleration driving method of a stepping motor, and belongs to the technical field of stepping motor driving of automobile instruments. Background technique [0002] In the design of automobile instruments, the key technology of driving the tachometer with pointer indication by the stepper motor is how to control the walking state of the stepper motor to achieve the ideal visual effect. The existing technology is mainly based on some theoretical parameters, such as trapezoidal acceleration and deceleration methods. However, in the actual processing process, especially for the engine tachometer, the pointer indication with high real-time requirements requires specific processing of acceleration and deceleration according to the law of the entire driving data, especially during the acceleration and deceleration process. The problem of acceleration and deceleration con...
