Embodiment 1

[0036] For the above application scenarios, this example provides a speed control method for wipers. The design idea of ​​this method is: convert the one-way motion of the motor into the reciprocating motion of the wiper, and control the motor during the one-way motion of the motor The target drive effective voltage, so that the motor adjusts the movement speed of the wiper based on the target drive effective voltage.

[0037] Through the above-mentioned design idea, in the process of driving the wiper to and fro by the motor in one direction, the driving effective voltage of the motor is controlled, and then the variable speed movement of the wiper is controlled, for example, the wiper can be slowed down near the reversal point, The middle area controls the accelerated operation of the wiper in a certain way to increase the wiping speed, so as to ensure that the running speed of the wiper can be adjusted in the entire wiping cycle, reduce the elastic deformation of the wiper b...

Abstract

The invention relates to a wiper speed regulation control method. The method comprises steps that an angular interval in which a motor rotates one circle is divided by one single Hall signal of a single Hall sensor into a first angular interval and a second angular interval; target angular velocity functions of the motor are set for the divided angular intervals, and the target angular velocity functions are piecewise functions; target driving effective voltages corresponding to the target angular velocities are calculated through the target angular velocities expressed by the piecewise functions, during one-way movement of the motor, and the motor is driven by the target driving effective voltages to make the motor adjust the movement speed of a wiper based on the target driving effectivevoltages. Through controlling the driving effective voltages of the motor, the variable motion of the wiper is controlled, the wiper is made to slow down near a reversal point, in the middle area, the wiper is controlled for acceleration in a certain way, the speed of the wiper is improved, that the wiper can be adjusted in speed throughout the wiper cycle is guaranteed, elastic deformation of ablade during high-speed scraping is reduced, and the wiper reversal noise is further reduced.

Description

technical field [0001] The invention relates to the technical field of wiper speed regulation, in particular to a wiper speed regulation control method, a speed regulation control system and a speed regulation controller. Background technique [0002] Wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to wipe off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety. [0003] The wiper is controlled by the high-speed gear and the low-speed gear respectively to perform high-speed wiping and low-speed wiping. Among them, the wiper is driven by the motor through the connecting rod structure. There are two general driving methods: [0004] One driving method is that the motor runs at a uniform speed in one direction, and then through the connecting rod structure, the one-way movement of one circle is converted into the reciprocating motion of the wiper on the glass surface;...
