According to the invention, through the adoption of the active pre-warning system, the system is used for actively performing protecting actions after the central processor computer judges camera-collected information; meanwhile, the central processing unit actively interferes with vehicle behaviors and warns personnel in the vehicle through the audible alarming system so that pre-warning failure caused by unconscious behaviors of passengers due to not understanding meanings expressed by an alarming signal is avoided.
Description
Technical field
The present invention relates to field of vehicle safety, particularly forewarn system is assisted at a kind of active vehicle rear.
Background technology
Along with the concern to vehicle safety performance, such as forward direction intelligent collision warning system, the various driving such as Lane Departure Warning System assists forewarn system to obtain increasing application, these forewarn systems can give chaufeur and warn accordingly or information before the dangerous driving situations such as collision or run-off-road occur, thus avoided the generation of accident.But assist for forewarn system for current driving, it also exists the problem in two when early warning.One, these early warning signals are mostly arranged on gauge panel, and this is making cumbrous to the requisite space of gauge panel while, also need chaufeur to divert sb.'s attention and watch its alarm content, easily the attention of dispersion chaufeur, thus cause new potential safety hazard.They are two years old, the early warning information of conventional forewarn system is similar at present, easily cause the misunderstanding of chaufeur and obscure, because chaufeur needs the driving condition processed according to current driving environment and analyze residing for it in driving procedure, this is a kind of information process of complexity, for the chaufeur that experience is still shallow, common alarm pattern and such as " drip drip ", " too " etc. early warning sound be not enough to allow it understand current unsafe condition fast and effectively, thus make it cannot make correct response fast, have impact on actual early warning effect.
Summary of the invention
When stopping, rear is observed not enough to overcome chaufeur and passenger, unconscious enabling causes and damages to pedestrian and vehicle rear, the invention provides a kind of active vehicle rear and assist forewarn system, effectively prevent personnel's dispersion attention, raising early warning effect by bus.
Technical scheme of the present invention is:
Forewarn system is assisted at a kind of active vehicle rear, comprises central processor unit and difference connected vehicle-mounted pick-up head unit, radar sensor, audible alarm system and electronic lock controller, wherein,
Described vehicle-mounted pick-up head unit comprises two and is installed on the camera of the tailstock for perception parking rear car rear road conditions, and after automobile stops, camera detects back car situation, and the video of shooting or image are sent to central processor unit;
Described radar sensor comprises two and is installed on the ultrasonic detector of the tailstock for the abnormal object distance in perception rear, and detection information is sent to central processor unit;
Described central processor unit, the particular location of the detection information danger factor to external world that the video image information sent according to camera and ultrasonic detector send identifies, and sends instruction to audible alarm system and electronic lock controller;
Described audible alarm system, uses vehicle audio, utilizes sound speaker to carry out information warning, reminds rear pedestrian and sends a car, carrying out audio alert to occupant;
After described electronic lock controller receives alerting signal, of short duration locking is carried out to the car door of alerting signal source direction.
Preferably, two cameras of described vehicle-mounted pick-up head unit are installed on the two ends, left and right of the tailstock respectively, the road conditions within the scope of the 45° angle of shooting left and right, car rear.
Preferably, described central processor unit is communicated with electronic lock controller with audible alarm system respectively by CAN.
Preferably, described central process unit is placed in the console of vehicle, starts when vehicle levels off to and stops.
Preferably, described electronic lock controller controls the open and close of left and right sides car door by middle control electronic lock.
Advantage of the present invention is:
1. forewarn system is assisted at the active vehicle rear that the present invention carries, formula of taking the initiative alarm mode, according to central process unit computer, judge initiatively to carry out protective action afterwards to camera collection information, central processing unit is initiatively interfered vehicle behavior simultaneously, and by audible alarm system, occupant is warned, avoid passenger do not understand alerting signal " tick " " too " meaning expressed time make automatism and cause early warning to be lost efficacy.
2. audible alarm system of the present invention, adopts CAN communication to connect auto audio equipment, does not change electronics framework and increases cost, make alarm sound soft, not ear-piercing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the schematic diagram that forewarn system is assisted at active vehicle rear of the present invention.
Detailed description of the invention
As shown in Figure 1, forewarn system is assisted at disclosed active vehicle rear, comprises central processor unit and difference connected vehicle-mounted pick-up head unit, radar sensor, audible alarm system and electronic lock controller, wherein:
Described vehicle-mounted pick-up head unit comprises two and is installed on the camera of the tailstock for perception parking rear car rear road conditions, and after automobile stops, camera detects back car situation, and the video of shooting or image are sent to central processor unit; Two cameras of described vehicle-mounted pick-up head unit are installed on the two ends, left and right of the tailstock respectively, the road conditions within the scope of the 45° angle of shooting left and right, car rear.Described radar sensor comprises two and is installed on the ultrasonic detector of the tailstock for the abnormal object distance in perception rear, by ultrasonic transduter, the distance of abnormal object distance vehicle body and foreign matter gait of march are calculated, and result is sent to central processor unit.Central process unit is calculated rear foreign matter course of action by image and radar sensor, and whether judging now opens the door to there will be jeopardizes the situation of rear by vehicle, then initiatively assign instruction to audible alarm system and electronic lock controller.
Described central processor unit, the particular location of the detection information danger factor to external world that the video image information sent according to camera and ultrasonic detector send identifies, and sends instruction to audible alarm system and electronic lock controller; Central processor unit is placed in the console of vehicle, start when vehicle levels off to and stops, now vehicle-mounted camera transmits rear images as reference, vehicle-mounted camera takes rear images continuously subsequently, depict abnormal contour of object by 2, front and back image comparison, thus judge to determine that rear is abnormal as people or Moped Scooter to profile analysis.
Described audible alarm system and electronic lock controller are installed in console, after it receives the alarm command that central processing unit sends, in the short time (1-2 second), locking is carried out to warning direction car door, avoid causing collision of opening the door, voice guard sends warning by loud speaker simultaneously, prompting rear object.Described audible alarm system, adopt vehicle audio as voice guard, central processor unit is connected to by CAN communication, central processor unit is to the distance that image comparison analysis is obtained a result and radar sensor obtains, result is transmitted to voice guard in the mode of signal, carries out audio alert to occupant, which kind of foreign matter prompting rear is, direction, and Distance geometry speed.
