Description
Technical field
The present invention relates to a kind of field of automobile control, especially relate to a kind of intelligentized rear-view mirror system.
Background technology
Along with the raising of customer to the quality of the life requirement; Automobile has become a kind of capital consumption article; Recoverable amount is increasing; Increasingly competitive between the automobile vendor; The customer requires vehicle satisfying on the basis of riding instead of walk; Individual character fashion more, and traveling comfort, handling, safety had higher requirement.
Orthodox car passes to chaufeur through three back mirrors in left, center, right with the information of motor vehicle environment, thereby the guiding chaufeur is correctly driven.There is following shortcoming in this traditional back mirror:
1, visually have the blind area, the vehicle periphery information that chaufeur obtains is not comprehensive, might misoperation, cause traffic accident, and threaten the own person and vehicle safety with other people.
2, when running at high speed for a long time, back mirror reflects light, makes chaufeur visual fatigue easily, and is dizzy; During night travel, it is blind that refracted ray may make the chaufeur short time produce.
3, left and right back mirror becomes the car body ridge, and when running at high speed, it is bigger to produce air resistance, influences the high stability of automobile.
4, the information around can only display automobile is waited for the operation of chaufeur passively, can not initiatively intervene some emergency situations, does not promptly have intellectuality.
Patent Office of the People's Republic of China discloses a CN101380926A document on March 11st, 2009; Name is called automobile exterior-view apparatus; This automobile exterior-view apparatus comprises car left and right sides back mirror, camera, telltale and control module, at outside at least one camera backward of installing of car body; At least one telltale is installed in the car; Camera is connected with control module through lead with telltale.When automobile normal running, through control module control, telltale shows the image of left and right vehicle wheel both sides and back.The shortcoming of this automobile exterior-view apparatus is: only traditional rear-view mirror is simply replaced, do not have pro-active intervention function or warning function promptly not to have intellectuality.
Summary of the invention
The present invention solves the technical matters that the existing in prior technology back mirror does not have pro-active intervention or warning function, provide a kind of can be according to ambient conditions Autonomous Control vehicle assistant drive person's intelligent back vision mirror system.
The present invention is directed to above-mentioned technical problem mainly is able to solve by following technical proposals: a kind of intelligent back vision mirror system; Comprise rearview camera, ECU main frame and display; Said rearview camera is connected said ECU main frame respectively with said display; Said rearview camera is arranged on body exterior; The camera lens of said video camera is over against the vehicle body rear; Said display is arranged on the facia board; Said ECU main frame also connects steering indicating light and angular transducer; Said angular transducer closure dish, said ECU main frame include and can judge whether the rear has the scene analysis module of vehicle by the picture that rearview camera photographs.Rearview camera passes through the telltale real-time play with the scene that the rear photographs, and chaufeur can be understood the situation at rear through telltale, and has the field range bigger than traditional rear-view mirror.The ECU main frame can recognize through angular transducer whether steering wheel rotation turns to chaufeur.When chaufeur turns to and do not beat steering indicating light; The scene analysis module has vehicle close through the picture judgement that rearview camera photographs simultaneously; Then ECU main frame ACTIVE CONTROL turns to the steering indicating light flicker of a side, reminds the vehicle at rear to take care, and prevents collision case.
As preferably, the present invention also comprises steer motor, and said rearview camera is connected on the vehicle body through said steer motor, and said steer motor is electrically connected with said ECU main frame.Can rotate camera through steer motor and adjust shooting angle, thereby obtain bigger field range, especially help to move backward when turning to.
As preferably, the present invention also comprises memory device, and said memory device is connected with the ECU main frame.When vehicle stops; Rearview camera still can be in shooting state, simultaneously the scene that photographs is deposited in the memory device, can keep watch on the situation of rear view of vehicle like this; The collision if meet accident, only the record that need call in the memory device just can be traced the troublemaker.For conserve storage, camera can be adjusted into camera mode, and promptly every 3-5 second beats is taken the photograph a picture and deposited memory device in, rather than carries out video record.
As preferably; The present invention comprises that also taking forward sight camera that direction is a vehicle front, taking direction be that the left side of vehicle left side looks camera and take direction is that camera is looked on the right side on vehicle right side, and said forward sight camera, a said left side are looked camera and looked camera with the right side and be connected said ECU main frame respectively.Can take simultaneously from multi-angle during vehicle parking, the sidewipe collision of scraping at any like this position all can be by record.The picture that the camera of all directions photographs can be on telltale real-time play.
As preferably, the present invention also comprises ultrasonic probe, and said ultrasonic probe connects said ECU main frame, and said ECU main frame connects door lock controller, and said ultrasonic probe is arranged on the vehicle body both sides.Each car door is furnished with a ultrasonic probe, and when vehicle stopped, each ultrasonic probe detected in the corresponding car door opening scope whether obstacle is arranged.When certain ultrasonic probe had detected obstacle, the ECU main frame was controlled corresponding car door locking through door lock controller, forbids opening, and prevented that the collision of car door and obstacle from causing damage.After obstacle removed, car door can freely be opened.
As preferably, the present invention also comprise be arranged on body tail, detection direction be rear view of vehicle, with said ECU main frame bonded assembly ultrasonic probe, said ECU main frame also connects automobile brake system.During reversing, whether the ultrasonic probe of body tail detects the rear has the distance between obstacle and vehicle and the obstacle, and when hypotelorism, ECU main frame ACTIVE CONTROL brake system is braked, and prevents collision.Initiatively stopping distance can be set by chaufeur oneself.
As preferably, said ECU main frame comprises the car plate analysis module that can obtain the front vehicle number-plate number according to the picture analysis that rearview camera photographs.The number-plate number of front vehicle is extracted in the picture analysis that the car plate analysis module is constantly taken according to rearview camera, and number and epoch are together carried out record.When certain number-plate number in the certain hour continues to trail or repeatedly repeats to occur, can warn to chaufeur, avoid the chaufeur trip to be followed the tracks of, the individual privacy and the freedom of movement of protection chaufeur.
The substantial effect that the present invention brings is; Telltale can show the scene of rear view of vehicle and both sides; And according to circumstances make driver assistance automatically and move; The rear has car can play steering indicating light automatically when turning; The rear has obstacle to brake automatically during reversing; Have obstacle to lock a door automatically during parking near the car door, can avoid being followed the tracks of by the people to front vehicle analysis, the picture in the time of can writing down parking around the car helps to seek reason after extraordinary circumstances take place.
