Title:
CONTROL DEVICE AND METHOD FOR MOTOR OF POWER-OPERATED TAILGATE OF AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2018/205973
Kind Code:
A1
Abstract:
A control device and method for a motor of a power-operated tailgate of an automobile. The control device for a motor of a power-operated tailgate of an automobile comprises a controller (1), a drive module (2), a measurement unit (4), and a motor (3). The motor rotates to drive the power-operated tailgate of the automobile to rise and fall. The measurement unit measures the actual rotating speed of the motor, and provides the actual rotating speed of the motor to the controller. The controller computes the duty cycle of the drive module according to a proportional-integral algorithm. The controller sets a value of a proportion coefficient in the proportional-integral algorithm according to a difference between the actual rotating speed of the motor and a target rotating speed of the motor. According to the duty cycle, the drive module drives the motor to rotate. In the control device and method, the PI algorithm is optimized, and accordingly, the operation stability of the motor is improved.
