Intelligent speed-adjusting control method of vehicle wiper

Abstract

The invention discloses an intelligent speed-adjusting control method of a vehicle wiper. Any structure of the existing wiper device does not need to be changed, a rain quantity sensor does not need to be additionally arranged, some agreed opening and closing operation methods are adopted, and the speed adjusting can be executed by a controller. A driver can make judgments according to the rain quantity, can freely set the rain wiping intermittent time and the rain wiping speed of the wiper by carrying out the simple opening and closing operations, and can freely select the satisfied control values. The problems of reliability and difficult optimum matching of rain wiping speed and rain quantity in the prior art are solved. The vehicle wiper has the advantages that the cost is low, the function is higher, the operation is convenient, the safety and the reliability are realized, and the vehicle wiper is ideal for vehicles, especially for medium-end and low-end vehicles.

Description

technical field [0001] The invention relates to the field of automobiles, and more specifically relates to an intelligent speed regulation control method for a wiper blade for a vehicle. Background technique [0002] At present, there are many technical methods for controlling the wiping speed of existing wipers for vehicles. The most mainstream and basic technical solutions are: intermittent (INT) gear, slow speed (I) gear, fast (II) gear, etc. Three kinds of wiper speed control, the intermittent gear is completed by the intermittent controller, and the intermittent time is fixed; the slow gear and the fast gear are determined by the structure of the motor body, and the slow or fast speed is also fixed. The shortcoming of this technical method is: because the size of rainfall is uncertain, and the speed of wiping water is too single, its speed is difficult to match with rainfall, and often it is not fast or slow, and fast will bring unnecessary wind. The scraping noise an...

Problems solved by technology

The shortcoming of this technical method is: because the size of rainfall is uncertain, and the speed of wiping water is too single, its speed is difficult to match with rainfall, and often it is not fast or slow, and fast will bring unnecessary wind. The scraping noise and too much interference with the driver's sight, if it is too slow, it will be too late to wipe off the rainwater and block the driver's sight

This method optimizes the intermittent time control, but it is not thorough. One is that the maximum wipe interval time is fixed, and the other is that the need to increase the gear switch will increase the system cost, and the choice of the wipe interval time is arbitrary. The performance is still not enough, and it cannot achieve the best match with the rain; the other is the rain sensor wiper, that is, the intermittent gear, the slow gear or the fast gear are automatically selected through the rain sensor to sense the amount of rain, thus saving the driver from operating these three. The action of the gear switch, this method is essentially the same as the most basic technical solution introduced above from the aspect of wiper speed regulation, but the system cost is much higher, and this method has the most deadly The defect is that once the rain sensor is blocked by mud or other colloids, it will wipe in fast gear
