Abstract
The utility model relates to a novel automatic wiper control device, which aims to solve the problems of complicated structure and low reliability in the prior art. The control device comprises a controller, a wiper driving device connected with the controller and a rainfall sensor. The rainfall sensor is provided with a built-in CPU connected with the controller. The device adopting the CPU has simple structure and high reliability, and uses a central centralized controller and a serial communication network bus to further lower manufacturing cost and provide possibility for wide use of family saloons.
Description
Technical field
The utility model relates to automobile manufacturing field, and in particular, the utility model is about a kind of later-model automatic wiper control setup of automobile automatically controlled.
Background technology
At present, safety and traveling comfort are that the customer pursues one's goal, and also are the directions that auto vendor makes great efforts, and the automatic wiper control system is just meeting this requirement.And present most of automobile still uses the wiper of manual control, mainly is because present automatic wiper control system reliability is not high.
Patent Office of the People's Republic of China discloses a CN201247318Y document on May 27th, 2003, name is called screen wiper, the characteristics of this wiper are in the automobile top direction of facining the wind a specially designed rain sensor to be installed, real-time identification also detects rainfall (snowflake, sleet) size, automatically operate in optimum speed (shelves) state by micro controller system instruction wiper electrical motor, chaufeur needn't just can have good sight line by frequent operation all the time.Its shortcoming is to use the single chip computer architecture complexity, and reliability is not high.
Summary of the invention
The utility model is for solving the complex structure that exists in the prior art, and the problem that reliability is not high provides a kind of later-model automatic wiper control setup, for a large amount of uses of family saloon provide may.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model comprises controller and the windscreen wiper actuating device that links to each other with controller, also comprises rain sensor, and rain sensor is provided with built-in CPU, and CPU links to each other with controller.The function of rain sensor is based on the principle of optics, be transferred to receptor by the light beam that built-in projector produced by complete principles of internal reflection, any moisture in predefined induction range or aqueous vapor all can form the path of light beam and disturb, these interference are monitored and are diagnosed by complicated circuit by a built-in intelligent processor, the signal that monitors sends controller to after handling by built-in CPU, by the rainfall size information control windscreen wiper actuating device that controller transmits according to rain sensor, realize the automatic wiper of windscreen wiper or stop; Owing to adopt built-in CPU, therefore simple in structure, reliability improves greatly.
As preferably, controller is central central controller.Utilize the controller of the existing central central controller of automobile, simplified circuit and reduced manufacturing cost as wiper.
As preferably, rain sensor links to each other with controller by the serial communication network-bus.Serial communication network-bus LIN BUS is a kind of data bus cheaply, has the advantage of low cost, high reliability.
The beneficial effects of the utility model are: the rain sensor that adopts built-in CPU, simple structure, high reliability, utilize central central controller, the serial communication network-bus of automobile itself further to reduce manufacturing cost, for a large amount of uses of family saloon provide may.
Description of drawings
Fig. 1 is a kind of functional block diagram of automatic wiper control setup of the present utility model.
Among the figure: 1. rain sensor, 2. central central controller, 3. windscreen wiper actuating device, 4. serial communication network-bus.
The specific embodiment
Embodiment:
A kind of later-model automatic wiper control setup of present embodiment referring to Fig. 1, comprises rain sensor 1, central central controller 2, windscreen wiper actuating device 3, and rain sensor 1 links to each other with central central controller 2 by serial communication network-bus 4 with windscreen wiper actuating device 3; Rain sensor 1 is installed in automobile external, detect exterior rainfall size, be transferred to receptor by the light beam that built-in projector produced by complete principles of internal reflection, any moisture in predefined induction range or aqueous vapor all can form the path of light beam and disturb, these interference are monitored and are diagnosed by complicated circuit by a built-in intelligent processor, the signal that monitors sends testing result to central central controller 2 by serial communication network-bus 4 after handling by built-in CPU, and central central controller 2 is controlled the speed and the start and stop of windscreen wiper actuating devices 3 by serial communication network-bus 4 according to the size of rainfall.
Above embodiment is one of preferred plan of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
