Spray-adjustable wiper control method and system

Abstract

The invention provides a jet-adjustable windscreen wiper control method and system. The method includes the following steps that 1, according to the environmental resistance condition of jetting of awindscreen wiper, the target jet pressure is calculated; 2, under the vehicle static and wind-free conditions, the basic jet volume required by every half wiping period is determined, and according tothe basic jet volume and the jet stage, the target jet volume required by every half wiping period is determined, wherein the step 1 and the step 2 can be exchanged; 3, according to the target jet pressure and the target jet volume, the main jet time corresponding to each half wiping period is calculated; 4, according to the target jet pressure, the target jet volume and the main jet time, the jet work of the windscreen wiper is controlled. According to the jet-adjustable windscreen wiper control method and system, the adjustability of the jet work is achieved, and resources are easily saved.

Description

technical field [0001] The invention relates to the technical field of wiper wiping for vehicles, in particular to a control method and system for a wiper with adjustable spraying. Background technique [0002] The detergent injection pressure of the wiper of existing vehicles is generally fixed, but the environmental factors of the wiper work are not always the same, and more or less change. For example, due to different vehicle speeds, wind resistance has different resistance to nozzle injection, and it is difficult for a fixed injection pressure to fully match different resistance conditions. Generally, in order to meet the required injection quantity requirements under all conditions, the injection quantity will be configured to match sufficient injection pressure even under high vehicle speed and high wind resistance conditions. This will have the following disadvantages: (1) when the vehicle is running at a low speed, the injection resistance is small, and excessive i...

Problems solved by technology

This will have the following disadvantages: (1) when the vehicle is running at a low speed, the injection resistance is small, and excessive injection pressure will cause excessive consumption of the washing liquid; (2) in order to ensure sufficient washing liquid cruising range, the volume of the washing pot should Larger, increasing the layout space of the washing pot; (3) The storage of washing liquid increases, increasing the weight of the vehicle, which is not conducive to the idea of ​​energy saving and emission reduction of the vehicle
