Wiper intelligent control method and device

Abstract

The invention discloses a wiper intelligent control method and device. The wiper intelligent control method simultaneously realizes a manual wiper adjustment function and a rainfall sensing automaticwiper adjustment function, and the two functions can work interactively; and in an automatic wiper working state, the wiper movement speed preset according to the rainfall amount can be manually adjusted until the wiper movement speed required by a driver is reached, so that the wiper movement speed meets the specific requirements of the driver at the time and meets the requirements of individualdifferences of the driver. According to the wiper intelligent control method and device, the current wiper movement speed under the automatic wiper working state can be locked to the wiper movement speed under the manual wiper working state at any time, and when the wiper movement speed is not the wiper movement speed required by the driver, the current wiper movement speed can be manually adjusted until the wiper movement speed required by the driver is reached; and thus multistage manual adjustment of the wiper movement speed of a wiper is realized, the operation is simple, and the efficiency of adjusting the wiper movement speed is improved.

Description

technical field [0001] The invention relates to the field of wiper control, in particular to an intelligent control method and device for a wiper. Background technique [0002] The wiper is an indispensable electrical device for motor vehicles, which is used to help motor vehicle drivers obtain a better observation field of vision when driving, so as to better ensure driving safety. At present, there are two types of wipers installed on motor vehicles: 1. Manual wipers; manual wipers are usually set with 6 working gears: 1-stop, 2-jog, 3-intermittent, 4-slow, 5-fast, 6- Cleaning; 2. Automatic wiper; automatic wiper uses rain sensor to realize automatic wiper. As we all know, the shifting operation of the manual wiper is realized by the driver of the motor vehicle manually turning the mechanical electrical switch. The automatic wiper senses the amount of rain outside the motor vehicle through the rain sensor, and automatically adjusts the movement speed of the wiper through ...

AI Technical Summary

Problems solved by technology

[0003] But present manual wiper and automatic wiper have following many deficiencies in actual use: one, manual wiper is provided with 6 working gears usually, and the driver must be manually adjusted to the required correct gear accurately during operation , and must be adjusted according to the order of the gears, and cannot be over-shifted, the operation is complicated, and the execution efficiency is low

2. The wiper movement speed of the automatic wiper is determined by the amount of rain sensed by the rain sensor (this is an objective amount), and the wiper speed cannot be adjusted flexibly. Due to the individual differences of each driver, under the same rainfall, The requirements for the wiper movement speed are not the same, and even the same driver will have the same requirement for the wiper movement speed under the same rainfall at different times and under different physical conditions (this is subjective) Require)

At present, the wiper movement speed of the automatic wiper is only controlled by the amount of rain, and the driver of the motor vehicle cannot actively adjust it, which leads to the contradiction between the subjective and the objective.

[0004] To sum up, the current motor vehicle wiper technology is still in the manual wiper and automatic wiper are separated in different independent systems, and one of them must be manually selected when using it. When the manual wiper is working, the automatic wiper cannot work, and vice versa.

When the automatic wiper is working, manual operation cannot affect (or change) the wiper movement speed automatically set by the rain sensor according to the amount of rain; when the manual wiper is working, the amount of rain sensed by the rain sensor cannot affect (or change) the driver The wiper movement speed selected by manual operation, that is, the wiper movement speed selection of manual wiper is only: "intermittent", "slow", "fast", poor flexibility
