[0072] In another aspect, the application provides a front windshield cleaning method, comprising the following steps:

[0073] Step S1: obtaining the running state of the vehicle and weather information;

[0074] Step S2: selecting the spray mode of the washing liquid spray device based on the preset liquid delivery rule and spray rule according to the running state of the vehicle and weather information.

[0075] The running state of the vehicle includes the running speed of the vehicle; the weather information at least includes: rainy day, foggy day, sunny day information, weather level;

[0076] The step S2 specifically includes:

[0077] Step S21: defining the priority of the spray mode according to the running state of the vehicle and weather information, wherein the priority is ranked in the order of: foggy day > rainy day > running speed;

[0078] Step S22: selecting the spray mode of the washing liquid spray device according to the preset liquid delivery rule and spray rule based on the priority of the spray mode.

[0082] For example, when it is detected that the weather at the vehicle driving position at the current time changes from sunny day to foggy day, and the foggy day level is heavy fog level, the spray duration, spray cycle and spray intensity information corresponding to the heavy fog level are adjusted, and the fan-shaped spray is selected, so that the fog, dust or stains can be better dispersed and removed, and the driver's vision is clear.

[0083] For example, when the weather is sunny, the columnar spraying mode is selected when the vehicle speed is greater than the vehicle speed preset value, and the fan-shaped spraying mode is selected when the vehicle speed is less than or equal to the vehicle speed preset value. For example, the vehicle speed preset value is 20 km / h, the vehicle speed is 18 km / h at this time, and the spraying information matching the vehicle speed is selected according to the washing liquid delivery rule and the spraying rule. The advantage is that when driving in sunny weather, the external view of the driver is relatively clear, and when the vehicle speed is high, the columnar spraying is used to prevent the high vehicle speed from affecting the view of the driver, so as to avoid traffic accidents.
