Abstract
Car door opening safe early warning ancillary system of the present utility model, the phonetic alarm comprising control unit and be connected with control unit and for monitoring rear mobile object and monitoring data being transferred to multiple radar sensors of control unit, described radar sensor is arranged on rear bumper, also comprise the Door Lock for the multiple door handle sensor and controlled unit controls that identify driver and crew's door opening action be connected with control unit, described door handle sensor is arranged at inside door handle place.Effective object of the present utility model is driver and crew, it is dual prompting on door opening action and voice, even if people after a stop of the vehicle, hand carries out door opening action, but because car door cannot be opened, compare this effect by the sense of hearing and visual alarm of prompting label prompting rear chaufeur and car interior installation speech sound alarming device or light alarm more effective, Peril Incident more can be avoided to occur.
Description
Technical field
The utility model relates to a kind of car door opening safe early warning ancillary system, belongs to vehicle application technology field.
Background technology
Along with economic develop rapidly, one of automobile main traffic instrument having become people, according to statistics, traffic accident greatly occurs after parking, reason is that people forget other vehicles of observing outside car when getting off and directly open car door, the vehicle of coming from rear, because having little time to dodge thus colliding, causes traffic accident.At present, more existing car door opening prior-warning devices: the first, paste at car door side posting reminder or install Warning light, but prompting label and Warning light are mainly used for pointing out front vehicle, prompting label and Warning light are easily by the impact of light, visual angle and distance, and front vehicle chaufeur easily ignores prompting label; The second, the vehicle had installs speech sound alarming device or light alarm in car, but when car stops, the hand of people has been placed on grip handle, habitually will go to open the door, still can cause the generation of Peril Incident; Three, utilize doubling ancillary system, doubling ancillary system is the competence exertion effect when vehicle reaches certain speed, and the vehicle of prompting chaufeur blind area, can not play its effect when vehicle stops.
Utility model content
The utility model, in order to overcome the deficiency of above technology, provides a kind of car door opening safe early warning ancillary system, and when can prevent car door opening, rear mobile object damages the people that gets off, the generation avoided traffic accident.
The utility model overcomes the technical scheme that its technical matters adopts:
A kind of car door opening safe early warning ancillary system, the phonetic alarm comprising control unit and be connected with control unit and for monitoring rear mobile object and monitoring data being transferred to multiple radar sensors of control unit, described radar sensor is arranged on rear bumper, also comprise the Door Lock for the multiple door handle sensor and controlled unit controls that identify driver and crew's door opening action be connected with control unit, described door handle sensor is arranged at inside door handle place.
Preferred according to the utility model, described radar sensor can monitor that rear bumper rear width is greater than W, angle is α=30-90 ° and area division within the 800m of rear bumper rear.
Further preferred, it is W+3 rice, angle [alpha]=45-60 ° and the area division within the 60m of rear bumper rear that described radar sensor can monitor rear bumper rear width.
Preferred according to the utility model, described radar sensor is 2-5.
Preferred according to the utility model, described control unit is MCS-96 micro controller system.
The beneficial effects of the utility model are:
1, whether the utility model is by having mobile object to control Door Lock in the certain area of radar sensor monitoring rear, if there is mobile object, it is invalid that driver and crew open the door first time, and car door cannot be opened, and with voice message; Second time is opened the door effectively, and car door opening, without voice message.If without mobile object, car door is directly opened, without voice message.Effective object of the present utility model is driver and crew, it is dual prompting on door opening action and voice, even if people after a stop of the vehicle, hand carries out door opening action, but because car door cannot be opened, compare this effect by the sense of hearing and visual alarm of prompting label prompting rear chaufeur and car interior installation speech sound alarming device or light alarm more effective, Peril Incident more can be avoided to occur.
2, the utility model adopts radar sensor, and the electromagnetic wave beam of radar emission has certain subtended angle, and the distance that tests the speed farthest is 800m, and the data being calculated radar sensor feedback by control unit can select effective working distance; And radar beam is large compared with the shadow surface of laser beam, be easier to captured target, need not fine sight.
3, ancillary system of the present utility model is started working under Parking situation, and comparing doubling ancillary system just can only start working when certain speed, and the utility model has more the effect of crashproof, anti-wound when driver and crew get off.
Accompanying drawing explanation
Fig. 1 is the module diagram of the utility model car door opening safe early warning ancillary system.
Fig. 2 is the radar sensor monitored area schematic diagram of the utility model early warning ancillary system.
In figure, 1, control unit, 2, door handle sensor, 3, Door Lock, 4, phonetic alarm, 5, radar sensor, 6, car door, 7, rear bumper, the maximum width that W, both sides car door are opened afterwards completely and car body is added up, the maximum angle of the electromagnetic wave beam that α, each radar sensor are launched.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As Fig. 1, shown in 2, car door opening safe early warning ancillary system of the present utility model, the phonetic alarm 4 comprising control unit 1 and be connected with control unit and for monitoring rear mobile object and monitoring data being transferred to multiple radar sensors 5 of control unit, described radar sensor 5 is arranged on rear bumper 7, also comprise the Door Lock 3 for the multiple door handle sensor 2 and controlled unit controls that identify driver and crew's door opening action be connected with control unit, described door handle sensor 2 is consistent with the quantity of Door Lock 3, described door handle sensor 2 is arranged at inside door handle place.
Radar sensor 5 can monitor that rear bumper rear width is greater than W, angle is α=30-90 ° and apart from the area division within the 800m of this car rear; Preferable width is W+3 rice, α=45-60 ° and the area division within the 60m of rear bumper rear, and the monitoring range of radar sensor 5 can self-defined amendment in control unit programming procedure, and described control unit is MCS-96 micro controller system.
When the vehicle is stopped, car door opening safe early warning ancillary system is started working, radar sensor 5 utilizes Doppler effect, namely mobile object has the calculation of effect of frequency displacement to draw the distance of rear object to received electromagnetic wave, and the side-play amount calculating rear object in certain hour difference is to judge whether tested rear object moves, by data transfer to control unit 1, namely monitor and whether have vehicle in monitored area; And at this moment door handle sensor 2 has identified whether door opening action, and by Signal transmissions to control unit 1; When at this moment opening the door, if have mobile object in monitored area, in car during driver and crew's first time door opening, control unit 1 can control Door Lock 3 closedown to be made car door open and starts the unlatching of control phonetic alarm 4 to carry out voice message, when second time door opening, control unit only controls Door Lock 3 unlatching and makes car door opening, and phonetic alarm 4 does not work.When in monitored area without mobile object, when driver and crew open the door, control unit control Door Lock 3 open make car door opening, phonetic alarm 4 does not work.
