Problems solved by technology

[0005] In fact, after the current electronic wiper is wiped 100w to 150w times, the gap between the motor and the connecting rod becomes large and irregular. In the prior art, only the wiper angle and wiper parameters are calibrated according to the number of wipes, which cannot effectively deal with mechanical aging. the impact

Embodiment Construction

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] Such as Figure 1-3 As shown, the electronic wiper control method with self-learning function includes the following steps:

[0023] 1. Enable wiper dry wipe learning

[0024] 1.1 Make sure the glass is dry and free of foreign matter, long press the lever jog switch, the wiper moves upward slowly, when the wiper moves to the A-pillar position, release the lever switch, the wiper stops, the software records the current of the whole process and the current reaching the A-pillar Wiper dry wiper motor angle one;

[0025] 1.2 Long press the lever jog switch, the wiper moves downward slowly, when the wiper moves to the lower edge of the windshield, let go, the wiper stops, and the software records the current of ...

Abstract

The invention relates to an electronic windscreen wiper control method with a self-learning function. The method comprises the steps of enabling windscreen wiper dry wiping learning and enabling windscreen wiper wet wiping learning, collecting corresponding motor current, deflection angle and other parameters, and adjusting PID control parameters of a motor and the deflection angle of a windscreen wiper motor through a controller according to the dry wiping learning and the wet wiping learning. Different aging conditions of different motors under different working conditions can be effectively adapted, so that the windscreen wiper is more harmonious and smooth in wiping, and meanwhile, the situation that the windscreen wiper hits an A column due to a large connecting rod gap is avoided.

Description

technical field [0001] The invention relates to the technical field of electronic wiper control, in particular to an electronic wiper control method with a self-learning function. Background technique [0002] Existing automobile wipers include motors, reducers, rocker shafts, four-bar linkages, wiper arms, etc., with complex structures and bulky volumes, and the speed regulation of the wipers is inconvenient. [0003] In view of the above defects, the Chinese invention patent CN101875342A discloses an automobile electric wiper and its control method. The automobile electric wiper includes a first servo motor and a first wiper arm. The output of the first servo motor passes through the first coupling and the second A wiper shaft is connected, a first wiper arm is provided on the first wiper shaft, and the first wiper arm swings with the rotation of the first wiper shaft, wherein, the motor shaft of the servo motor is provided with The first position detection device; the fi...
