Abstract
The utility model relates to the field of warning of car reversing, in particular to an alerting system for a car reversing light which is out of work. The alerting system for the car reversing light which is out of work comprises a left chip arranged in a left reversing light and a right chip arranged in a right reversing light, wherein the left chip and the right chip are respectively connected with a controller. The other input end of the controller receives a car reversing signal discharged from a car reversing switch, one output end of the controller is connected with a back fog lamp switch, and the other output end of the controller is connected with an alerting unit. The controller detects the left chip and the right chip when receives the car reversing signal, and if the left car reversing light or the right car reversing light is out of work, the controller drives the alerting unit to raise an alarm to alert an driver. When both the left car reversing light and the right car reversing light are out of work, the controller turns on the back fog lamp switch to achieve automatic lighting of a back fog lamp, and the back fog lamp replaces the car reversing light temporarily to achieve the aim of alerting cars on the behind and passengers on the periphery.
Description
Technical field
The utility model relates to reversing caution field, the particularly caution system of backing-up lamp inefficacy.
Background technology
At present, after vehicle was hung reverse gear, backing-up lamp can automatically light and play by day other vehicles of caution and passerby dodges, and also played effect to the vehicle rear illumination except warning function at night.But when backing-up lamp itself broke down, backing-up lamp can't be lighted, at chaufeur and when not knowing that backing-up lamp lost efficacy in the reversing process other vehicles and passerby can not predict in advance this car and will move backward, cause easily traffic accident.And at night without backing-up lamp illumination chaufeur to the rear view of vehicle road invisibility hidden danger that also can cause the accident.
Summary of the invention
The purpose of this utility model provides a kind of timely prompting backing-up lamp fault and automatically lights the caution system of the backing-up lamp inefficacy of fog tail lamp illumination.
For achieving the above object, the utility model has adopted following technical scheme: the caution system that a kind of backing-up lamp lost efficacy, comprise the left chip and the right chip that are separately positioned in the left and right backing-up lamp, described left chip links to each other with controller respectively with right chip, another input end of controller receives the astern signal that reversing switch sends, the mouth of controller connects rear fog lamp switch, and another mouth of controller connects the caution unit.
Owing to adopt above technical scheme, when receiving astern signal, controller detects left chip and right chip, if left backing-up lamp or one of them inefficacy of right backing-up lamp, controller drives the caution unit reminding driver that gives the alarm; If when left backing-up lamp or the equal et out of order of right backing-up lamp, controller is opened rear fog lamp switch, realizes automatically lighting fog tail lamp, replaces backing-up lamp with fog tail lamp temporarily, play caution front vehicle and peripheral pedestrian's purpose, avoid drawing the traffic accident that backing-up lamp lost efficacy and causes.
Description of drawings
Fig. 1 is flow chart of the present utility model.
The specific embodiment
Such as Fig. 1, the caution system that a kind of backing-up lamp lost efficacy, comprise the left chip 11 and the right chip 12 that are separately positioned in the left and right backing-up lamp, described left chip 11 links to each other with controller 20 respectively with right chip 12, another input end of controller 20 receives the astern signal that reversing switch 30 sends, the mouth of controller 20 connects rear fog lamp switch 40, and another mouth of controller 20 connects caution unit 50.Controller 20 drives left chip 11 when collecting astern signal and right chip 12 is opened left and right backing-up lamp, if controller 20 detects left chip 11 and right chip 12 one of them et out of order, when being one of them inefficacy of left backing-up lamp or right backing-up lamp, controller 20 drives caution unit 50 reminding driver that gives the alarm, can allow chaufeur find that in time backing-up lamp damages, improve the vigilance of driving; If when left backing-up lamp or the equal et out of order of right backing-up lamp, controller 20 is opened rear fog lamp switch 40, realize automatically lighting fog tail lamp, replace backing-up lamp with fog tail lamp temporarily, play caution front vehicle and peripheral pedestrian's purpose, avoid drawing the traffic accident that backing-up lamp lost efficacy and causes, and this system opens the not backing-up lamp of et out of order automatically by controller 20, avoid chaufeur to forget the phenomenon of opening backing-up lamp because of negligence of operation, further improve the safety performance of vehicle.Certainly this system also can light fog tail lamp automatically when the arbitrary et out of order of left and right backing-up lamp.Controller 20 in the utility model adopts car body controller BCM, need not additionally to set up controller, rationally utilizes element on the vehicle body, and simplified structure is saved cost.
Described caution unit 50 is for being arranged on the indicator lamp on the meter panel of motor vehicle, and caution unit 50 receives the indication rear drive indicator lamp flicker of controller 20, reminding driver.Can respectively corresponding left and right backing-up lamp of two indicator lamps be set at gauge panel, make things convenient for chaufeur from indicator lamp, can find out directly that just concrete which backing-up lamp is damaged.
Described controller 20 gathers astern signal by the CAN bus.Usually reversing switch 30 is connected Automatic Transmission control unit TCU on the automobile of automatic catch, had astern signal in the CAN bus, it is more quick that controller 20 directly reads this signal from CAN bus biography.
Described reversing switch 30 is connected with controller 20 circuit, and this scheme especially is adapted to the manual gear vehicle, and reversing switch 30 can transfer to controller 20 with astern signal by high level or low level form.
