Embodiment 1

[0035] 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.

[0036] 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 discloses a wiper speed regulating control method. The wiper speed regulating control method comprises the steps that a rotation angle interval of a motor is divided into four angle intervals through a double hall signal of a double hall sensor; target angular velocity functions of the motor are set for each divided angle interval, wherein the target angular velocity functions are piecewise functions; and target driving effective voltage corresponding to each target angular velocity is calculated through the target angular velocity expressed by each piecewise function, in the process of one-way movement of the motor, and the motor is driven to move by each target driving effective voltage to make the motor adjust the motion speed of a wiper based on each target driving effective voltage. By controlling the driving effective voltage of the motor to control variable motion of the wiper, for instance, the wiper can slow down near a reversal point, the wiper is controlled toaccelerate in a certain way in the middle of the reversal point, the wiper speed is increased, thus the adjustable speed of the wiper throughout the wiper cycle is ensured, elastic deformation of a blade during the high-speed wiper is reduced, and at the same inversion noise of the wiper is 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;...
