Abstract
The utility model provides an automatic cleaning system of a rearview mirror, which comprises the rearview mirror, a judgment unit, a detection unit and a control unit, wherein the judgment unit is used for judging igniting states of a motor, the detection unit is used for detecting environment states around a vehicle, the control unit is connected with the judgment unit, the detection unit and the rearview mirror and used for controlling rotation direction and rotation angles of the rearview mirror and cleaning the rearview mirror when the igniting states of the motor and the environment states around the vehicle meet preset conditions. The automatic cleaning system controls the rotation direction and the rotation angles of the rearview mirror when a vehicle body is in a rainy state and the motor flames out, solves the technical problem that the rearview mirror cannot achieve an automatic cleaning function, has good cleaning effect, does not affect rearview effect of drivers due to the fact that the automatic cleaning system performs cleaning when the vehicle motor is flamed out, and enhances driving safety.
Description
Technical field
The present invention relates to a kind of automobile and use back mirror, be specifically related to a kind of back mirror auto cleaning system.
Background technology
In the vehicle ' process, back mirror provides the rear view of vehicle visual field for the driver, and this has not only increased travel safety, has also improved driver's driving impression simultaneously.In the prior art, the cleaning of back mirror is mainly adopted the mode of manual cleaning or installation rearview mirror wiper blade device.Adopt when manually cleaning, the promptness and the cleaning effect of cleaning are relatively poor, and have reduced vehicle hommization and intelligentized level.
When cleaning through the rearview mirror wiper blade device is installed, because direction is omited towards ground at the angle of inclination of rear-vision mirror face, rainwater can not fully contact with rear-vision mirror face, and the effect of its cleaning is relatively poor; Because the area of rear-vision mirror face is less, the backsight effect that wiper has influenced back mirror is installed on back mirror, there is interference in the action of rearview mirror wiper blade device to chaufeur in the vehicle ' process in addition, has reduced travel safety.
Summary of the invention
The utility model provides a kind of back mirror auto cleaning system, has realized the automatic cleaning function to back mirror, and its cleaning effect is better, has strengthened travel safety.
A kind of back mirror auto cleaning system comprises back mirror, judging unit, detecting unit and control unit, and wherein, judging unit is used to judge the fired state of driving engine; Detecting unit is used to detect the ambient condition of vehicle periphery; Control setup is connected with judging unit, detecting device and back mirror, is used for satisfying when pre-conditioned at the fired state of driving engine and vehicle-periphery state, and the rotation direction and the rotational angle of control back mirror clean back mirror.
Said system also comprises timing unit, and timing unit is connected with control unit, time value that once cleans before being used to write down and current time value; Said control unit specifically is used for preceding time value that once cleans and the current time value acquisition time difference according to the timing unit record; And judge whether said time difference satisfies preset clean conditions; When judged result when being; The rotation direction and the rotational angle of control back mirror clean back mirror; Otherwise, do not control the rotation action of back mirror.
Above-mentioned detection device is a rain sensor, and said rain sensor is installed on the vehicle body, is used to detect vehicle body and whether is in rainy state and rainfall size.
Above-mentioned control setup specifically is used for, and is in rainy state when detecting vehicle, and when judging engine off, the rotation direction and the rotational angle of control back mirror.
The utlity model has following beneficial effect:
The utility model provides a kind of back mirror auto cleaning system, is in rainy state at vehicle body, and during engine off, the rotation direction and the rotational angle of control back mirror have been realized the automatic cleaning function to back mirror, and its cleaning effect is better; In addition, under vehicle motor is in flameout state, clean, do not influence the backsight effect of chaufeur, strengthened travel safety.
Description of drawings
Fig. 1 is the functional block diagram of the utility model.
The specific embodiment
The core concept of the utility model is, is in rainy state at vehicle body, and during engine off, the rotation direction and the rotational angle of control back mirror clean back mirror.The back mirror auto cleaning system that the utility model provides comprises back mirror, it is characterized in that: also comprise judging unit, detecting unit and control unit, wherein, judging unit is used to judge the fired state of driving engine; Detecting unit is used to detect the ambient condition of vehicle periphery; Control setup is connected with judging unit, detecting device and back mirror, is used for satisfying when pre-conditioned at the fired state of driving engine and vehicle-periphery state, and the rotation direction and the rotational angle of control back mirror clean back mirror.This system also comprises timing unit, and timing unit is connected with control unit, time value that once cleans before being used to write down and current time value.
Control unit specifically is used for preceding time value that once cleans and the current time value acquisition time difference according to the timing unit record; And judge whether said time difference satisfies preset clean conditions; When judged result when being; The rotation direction and the rotational angle of control back mirror clean back mirror; Otherwise, do not control the rotation action of back mirror.Detecting device is a rain sensor, and said rain sensor is installed on the vehicle body, is used to detect vehicle body and whether is in rainy state and rainfall size.Control setup specifically is used for, and is in rainy state when detecting vehicle, and when judging engine off, the rotation direction and the rotational angle of control back mirror; Control setup specifically is used for, and is in rainy state when detecting vehicle, and when judging engine off, according to the rotation direction and the rotational angle of the size control back mirror of said rainfall.Wherein, said back mirror rotational angle is associated with said rainfall size.Concrete, said back mirror rotational angle and said rainfall size are inversely proportional to.Need to prove, be in rainy state, and when judging engine ignition, do not control the rotation of back mirror when detecting vehicle.In addition, be in no rain state when detecting vehicle, no matter whether driving engine goes out under fired state, does not control the rotation of back mirror.The rotation direction of said control back mirror and rotational angle comprise, control setup drives back mirror and under preset rotation direction, rotates preset angle through the rotation of motor in the control back mirror, and back mirror is cleaned; Or control setup drives back mirror under preset rotation direction through the rotation of motor in the control back mirror, rotates repeatedly according to preset rotational angle range, and back mirror is cleaned.Wherein, the rotation direction of control back mirror makes progress for control rear-vision mirror face direction, and rainwater fully contacts with back mirror like this, and is better to the cleaning effect of back mirror.Control setup also is used for, and reaches predetermined threshold value at the cleaning time of said back mirror, controls said back mirror playback.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
