Abstract
The invention relates to a system and a method for controlling the time for spraying a cleaning solution. When a driver presses down a switch for spraying the cleaning solution, a car body controller detects the position of a scraping sheet, and only when the scraping sheet is positioned at the initial position, a washing motor is switched on to spray the cleaning solution.
Description
Technical field
The present invention relates to a kind of controlling schemes, relate to the restoring board structure of Body control module, washing motor and rain shaving electrical machine, be specifically related to a kind of time for spraying cleaning solution control system and control method thereof time for spraying cleaning solution.
Background technology
Chaufeur generally can be in the process of windscreen wiper wiper when utilizing scrubber and wiper that front windshield is cleaned, jet washing liquid.The position of scraping blade is all changing constantly, and the injection direction of nozzle is fixed, and following situation can occur sometimes:
1, spraying cleaning solution is on scraping blade, and the part cleansing fluid is wasted;
When 2, the scraping blade wiper is to the extreme higher position of windscreen, jet washing liquid, and scraping blade this moment can be at once the direct wiper of cleansing fluid in the roof drip, cleansing fluid is utilization completely.
Above-mentioned situation can cause the too much waste of cleansing fluid, and cleansing fluid consumption is serious, the filling cleansing fluid that chaufeur for this reason can be frequent.Also be to have following technical matters in the prior art: can't well coordinate the spraying cleaning solution time with the relation between the scraping blade path of motion, cause waste and inefficiency.
Summary of the invention
The object of the present invention is to provide a kind of time for spraying cleaning solution control system and control method thereof, good control injection opportunity, utilize cleaning liquid more fully, when preventing to spray, spraying cleaning solution arrived above the scraping blade or spraying cleaning solution below scraping blade by the direct wiper of scraping blade to roof drip, cause the waste of cleansing fluid.
When chaufeur was pressed the switch of jet washing liquid, car body controller detected the position of scraping blade, has only when scraping blade is positioned at initial position, just connects washing motor, jet washing liquid.
Concrete technical scheme is as follows:
A kind of time for spraying cleaning solution control system, comprise car body controller BCM, rain shaving electrical machine and washing motor, be electrically connected between car body controller BCM and rain shaving electrical machine and the washing motor or communication is connected, wherein, car body controller BCM is used to detect the signal of rain shaving electrical machine, and the mode of operation of algorithm controls rain shaving electrical machine and washing motor as required.
The signal that described car body controller BCM is used to detect rain shaving electrical machine is a reset signal.
Rain shaving electrical machine is connected with scraping blade, and car body controller BCM is used to detect the position of scraping blade, and the control washing motor only is positioned at the initial position connection at scraping blade.
Also comprise nozzle, the normal power supply of wiper switch and storage battery, described nozzle is used for jet washing liquid, the work that described wiper switch is used to control windscreen wiper whether, the normal power supply of described storage battery provides energy, its with other members between be conventional the connection.
Rain shaving electrical machine has restoring board, and it is continuous variable condition when windscreen wiper is worked, and car body controller BCM detects its state and determines the signal of rain shaving electrical machine.
The variable condition of restoring board is for rotating always.
Described restoring board has a reset pin and an inner draw-in groove, when scraping blade is in the desired location, and reset pin P
3Point overlaps with the inside draw-in groove of restoring board.
Described desired location is the initial position of windscreen wiper.
A kind of control method of above-mentioned time for spraying cleaning solution control system is pressed the switch of jet washing liquid when chaufeur, and car body controller detects the position of scraping blade, only when scraping blade is positioned at the desired location, and car body controller connection washing motor, jet washing liquid.
Its step is specific as follows:
(1) car body controller detects the reset signal of rain shaving electrical machine;
(2) car body controller is determined the real time position of scraping blade;
(3) be positioned at initial position when scraping blade, car body controller detects the unsettled signal of rain shaving electrical machine in-to-in and cuts off the power supply to rain shaving electrical machine;
(4) car body controller is given preceding washing motor energising, washing motor work, jet washing liquid.
Further comprise step (5): after whole course of injection finished, windscreen wiper worked on according to the position of switch again.
Compare with present prior art, the present invention controls the time point of spraying cleaning solution, prevents the waste that cleansing fluid is too much.The invention has the beneficial effects as follows that nozzle can accurately avoid spraying cleaning solution to avoid the waste of cleansing fluid to the first-class phenomenon of scraping blade spraying cleaning solution above windshield.

The specific embodiment
Describe the present invention with reference to the accompanying drawings below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
This spraying cleaning solution time controlling schemes mainly comprises: comprise washing motor and the preceding rain shaving electrical machine that has auto-reset function, front nozzle, car body controller, wiper switch, the normal power supply of storage battery at least.For realizing this mode, the reset signal of rain shaving electrical machine before car body controller need detect, to determine whether scraping blade is positioned at initial position this moment, when determining that scraping blade is positioned at initial position this moment, car body controller can detect the unsettled signal of rain shaving electrical machine in-to-in, at first cut off the power supply to rain shaving electrical machine, this moment, the scraping arm position was positioned at the initial position of windshield below, gave preceding washing motor energising then, washing motor work, jet washing liquid is accurately the top of spraying cleaning solution to scraping blade.The whole process BCM period is at 2-3 in second, need avoid cleansing fluid also do not spray do not come up in and the scraping arm setting in motion, after whole course of injection finished, windscreen wiper worked on according to the position of switch again.
When windscreen wiper was worked, restoring board was (shown in the Fig. 1,2) that is always rotating, when scraping blade wiper during to initial position, and P
3Point can overlap with the inside draw-in groove of restoring board.
When wash switch is put through, BCM begins to detect reset pin (P3 point) signal, P2 one directly, except scraping blade other positions initial position, P2 is in off-state with P3 always, and the signal that BCM detects is high (unsettled), when scraping blade moves to initial position, P2 is communicated with P3, and the signal that this moment, BCM detected is low (ground connection).This moment, BCM switches on to washing motor, washing motor work, with spraying cleaning solution on front windshield glass.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
