Abstract
The utility model provides a vehicle turning state detecting device based on an electronic sensor. The vehicle turning state detecting device comprises a vehicle state detection module arranged on a vehicle, wherein the vehicle state detection module is provided with a geomagnetic sensor and an acceleration sensor and is connected with an output module, and the output module is connected with a voice prompting device, a video prompting device and a record storage device which are arranged in the vehicle. Through adopting an electronic sensor technology, the test is sensitive and accurate, the turning state of the vehicle can be quickly and precisely judged, and misjudgment of the sensors is effectively avoided by combining the advantages of the geomagnetic sensor and the acceleration sensor.
Description
Technical field
The utility model relates to the electronic sensor technical field, is specially a kind of turn inside diameter condition checkout gear based on electronic sensor.
Background technology
Full size vehicle (as earthwork car, container car, long-traveller car etc.), when turning, the vision blind spot easily occurs at the left and right sides of vehicle, thereby often causes contingency.If can not rely on the operation of chaufeur, objectively detect the state while turning and propose warning or the vehicle-surroundings environment is monitored to (as automatically opened and recording image etc.), can greatly reduce the generation of contingency.
Modal turn inside diameter state-detection has following two schemes on the market at present:
1, by the Vehicular turn modulating signal,, when chaufeur is opened the left/right steering indicating light, by the steering indicating light signal, determine the turn inside diameter state; The driving habit of this chaufeur that places one's entire reliance upon, but in the contingency of Vehicle Driving Cycle, cause due to the inadvertent of chaufeur or bad driving habit, often so the shortcoming of this scheme maximum is to lack objectivity and validity.
2, GPS information, the method requires vehicle to install the GPS device additional, and determines the turn inside diameter state by longitude and latitude (variation) information of GPS.The information of the GPS satellite-signal that places one's entire reliance upon, if satellite-signal is lost (in tunnel), GPS is by entirely ineffective; In addition, at present in common vehicle GPS, the renewal frequency of latitude and longitude coordinates is 1 time/second, wants like this to judge by GPS the turn condition of vehicle, at least needs 1 second～time of 2 seconds, and such speed of response is quite disadvantageous to the prevention of contingency; Moreover GPS scheme price is relatively costly.
The utility model content
The technical matters that the utility model solves is to provide a kind of turn inside diameter condition checkout gear based on electronic sensor, to solve the problem proposed in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of turn inside diameter condition checkout gear based on electronic sensor, comprise vehicle-mounted vehicle-state detection module, and described vehicle-state detection module is provided with geomagnetic sensor and acceleration pick-up; Described vehicle-state detection module is connected with output module, is connected with the sound prompt device, image suggestion device and the record memory device that are arranged in car on described output module.
Further, described geomagnetic sensor adopts the MAG3110 chip, and described acceleration pick-up adopts the MMA7455L chip.
Beneficial effect:
The utility model is by the electronic sensor technology, tests sensitively, accurate, judges fast and accurately the turn condition of vehicle, and, in conjunction with the advantage of above-mentioned two kinds of sensors, the erroneous judgement of sensor effectively evaded.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of turn inside diameter condition checkout gear based on electronic sensor, comprise vehicle-mounted vehicle-state detection module, and described vehicle-state detection module is provided with geomagnetic sensor and acceleration pick-up; Described vehicle-state detection module is connected with output module, is connected with the sound prompt device, image suggestion device and the record memory device that are arranged in car on described output module.Described geomagnetic sensor adopts the MAG3110 chip, and described acceleration pick-up adopts the MMA7455L chip.
In the utility model, if do not consider external disturbance, the turn condition that detects vehicle that geomagnetic sensor and acceleration pick-up can both be sensitive.Yet geomagnetic sensor can produce error in judgement under electromagnetic interference, and acceleration pick-up can produce error in judgement at the road agitation that jolts.Consider the relative independentability of two kinds of interference, if the judged result of the judged result of geomagnetic sensor and acceleration pick-up is carried out rationally comprehensively, can greatly reduce the False Rate of vehicle running state.The utility model is by the electronic sensor technology, tests sensitively, accurate, judges fast and accurately the turn condition of vehicle, and, in conjunction with the advantage of above-mentioned two kinds of sensors, the erroneous judgement of sensor effectively evaded.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
