[0033] The application will be further described below in conjunction with the drawings and embodiments.

[0034] It should be noted that the following detailed description is merely exemplary and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0035] It should be noted that the terms used herein are merely for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should be further understood that the terms "comprise" and / or "include" as used herein indicate the presence of a feature, step, operation, device, component and / or a combination thereof.

[0036] The wiper controller is divided into two categories: positive control wiper controller and negative control wiper controller. The positive control is called positive trigger, and the signal line is triggered by high level. The negative control is called negative trigger, and the signal line is triggered by negative (ground). The signal line is connected to the negative, which can be directly triggered. The positive control is to control the positive, and the negative control is to control the negative. Each type of controller is divided into two small categories: intermittent adjustable and intermittent non-adjustable. This results in four states of wiper controller: negative control intermittent adjustable, negative control intermittent non-adjustable, positive control intermittent adjustable, and positive control intermittent non-adjustable. This leads to errors in production and assembly of wiper controllers, thereby reducing the efficiency of production and assembly.

[0037] Therefore, the following embodiments give a wiper control system, a control method and a motor vehicle, which concentrates the above four states in the same wiper controller, realizes compatibility, and improves the production and assembly efficiency and avoids the risk of wrong production and assembly.

[0060] As shown in Figure 4 , taking a positive control wiper as an example, when in use, the combination switch is switched between no-gear input, intermittent gear, low-speed gear and high-speed gear according to requirements;

[0061] When there is no-gear input, the wiper is static;

[0062] When in the intermittent gear, the pin 13 outputs intermittently (i.e., the high-level intermittent trigger of the low-speed movement of the wiper motor), and the wiper motor drives the wiper body to move at low speed intermittently;

[0063] When in the low-speed gear, the pin 13 outputs continuously (i.e., the high-level continuous trigger of the low-speed movement of the wiper motor), and the wiper motor drives the wiper body to move at low speed;
