Description
Technical field
The utility model relates to a kind of deviation annunciator, refers to that especially a kind of vehicle speed signal of cooperating and can directly utilizing global positioning system and provided of being connected with global positioning system (GPS) is to reach the deviation annunciator of deviation caution effect.
Background technology
The vehicle of automobile for popularizing, often installing various electronics additional along with user (driver) needs in recent years is equipped with, as global positioning system (global positioning system, GPS), deviation caution system (Lane Departure Warning System, LDWS), drive recorder (Event DataRecorder, EDR) etc., wherein, global positioning system (GPS) be utilize a gps receiver as global positioning system with C/A sign indicating number WGS-84 ellipsoidal coordinates with the car locating data in the satellite-signal that receives GPS, and can cooperate default electronic chart (e-map) and display screen so that the area at the present place of driving to be provided, the position, the orientation and the speed of a motor vehicle etc. are beneficial to the driver and grasp the driving trend at any time; Because global positioning system (GPS) has been a matured product, so in this not elsewhere specified (NES) its thin bilge construction and functions of use.
Existing deviation caution system (LDWS) mainly is to utilize a phtographic lens (camera/imagesensor) to be installed in Che Nei also to face car the place ahead in order to read the road image in car the place ahead, during use as travelling on express highway, generally be the white lane mark image that reads the track dual-side, and can set up track initial point, track vanishing point and car left and right sides deviation sensitivity when mounted earlier on their own with as identified parameters; Again the image that is read is imported the set electronic control unit (ECU of described deviation caution system (LDWS), electronic control unit) in, described electronic control unit (ECU) mainly comprises a digital signal processor (digital signal processor, DSP) and cooperate a storage location (memory unit) (random access memory is RAM) to handle image identification work as random access memory; Described electronic control unit (ECU) connects the left and right directions lamp of car or speed of a motor vehicle code table etc. again to obtain and to utilize the car body signal of car, to judge whether the being dangerous driving behavior, for example: the speed of a motor vehicle is per hour travelled on express highway more than 60 kilometers, and learn that by the car body signal person of driving does not handle left and right commentaries on classics lamp (not lane change), if be line ball or the state that crawls but deviation caution system (LDWS) picks out garage's direction with respect to lane mark, promptly stably between two lane maries, do not travel; If identification result is for being, then can transmission signals to warn unit (warning unit) as visual alarm unit (visual warning unit) and/or sense of hearing caution unit (audible warning unit) with start and in order to warning drivers, reach the action function of deviation caution system (LDWS).
Yet, to so far, existing its electronic control unit of deviation caution system (LDWS) (ECU) all is outwards to be connected to bearing circle or left and right directions lamp or speed of a motor vehicle code table to obtain car body signal such as the left and right directions lamp or the speed of a motor vehicle etc. by lead, be provided as identification and judgement in order to combine with the lane mark image, so that existing circuit and the outfit that deviation caution system (LDWS) Shi Douhui employs car is being installed, relatively easily causing the change of interior equipment of car and outward appearance; And because each factory's car type is a lot, each car type is equipped also or difference is arranged, and therefore is increased in the degree of difficulty when doing the connection of car body signal relatively; Especially the customer generally dislikes changing in order to install electronic machine additional or influences equipment and outward appearance in the car of original car, so reduce the wish of installation deviation annunciator relatively, is unfavorable for using the universalness and the service efficiency of deviation annunciator; Again, the car inner space is originally just limited, and global positioning system (GPS) has been adopted by most of car, but with deviation caution system (LDWS) for individual and must install respectively respectively, not only easily cause the inconvenience of installation, and can't be used in combination between the two, relatively also increase manufacturing cost and cost of installation, become and install sorry that these electronics are equipped with in the car additional, also influence the service efficiency that these electronics are equipped with relatively.
As from the foregoing, how designing a deviation annunciator can use onboard for the customer in easy installation, especially prior art can be replaced and car body signal such as mounting meanss such as the left and right directions lamp or the speed of a motor vehicle must be connected, by with comfort feature and service efficiency that the deviation annunciator promote to be installed and the acceptance that promotes the customer, be that exigence is arranged, the utility model promptly is need and to design at this.
