The specific embodiment
In general, the present invention relates to the technology of loudspeaker operation mode in a kind of signal enabling vehicle of specifying loudspeaker operation regulations in response to representative.
By adopting for example global position system of position fixing system (as GPS) and numerical map, and/or adopt traffic signal means of identification, can produce this signal.
Loudspeaker operation mode can be such pattern, wherein, when signal designation no horn or while not allowing sound level higher than specific rank, " ring loudspeaker are forbidden or limit " pattern is activated, wherein loudspeaker are disabled, or the sound level of loudspeaker is restricted to lower than specific rank, or produces warning and allow chaufeur know to forbid or restriction situation; And when signal designation must be carried out ring loudspeaker, " loudspeaker must ring " pattern is activated, wherein loudspeaker are started to produce sound automatically, or produce warning with driver operation loudspeaker.
Warning can be audio-alert or optics (video) warning, or the two.
Known thering are the loudspeaker operation regulations of specifying the area of loudspeaker operations regulations to be provided with traffic signal in various positions to indicate corresponding appointment, for example, along road or in various areas.These signals can be indicated the place of appointment, and for example road is joined or point of crossing, or the section of specifying, for example Yi Duan highway Huo Yiduan street, or the interval of specifying, for example dwelling district or government work district.
The traffic signal means of identification that vehicle carries can catch these traffic signal and produce corresponding signal.
Also can be at these place arranging electronic traffic marks.For example, electronic transmitter can be sent wireless signal, and its electronic receiver that can be carried by vehicle receives.
As additional or alternative, can be equipped with vehicle-mounted (being arranged on vehicle) numerical map, or be equipped with the outer numerical map of car, for example at traffic control center or service supplier there, be equipped with.Be provided with and specify the place of loudspeaker operation regulations to be incorporated in map.The system identification that can be positioned of the current location of vehicle.If be equipped with numerical map in traffic control center or service supplier there, vehicle is equipped with and the radio-type interface of traffic control center or service supplier's swap data.
No matter how, vehicle can receive the signal of indication about current location loudspeaker operation regulatory information.
In certain place, without any traffic signal or the regulations of relevant loudspeaker operation, vehicle is at this point put and can be made its loudspeaker with free schema work, and wherein chaufeur can determine whether operate loudspeaker according to actual traffic situation.
As position fixing system, it can at least comprise global position system (for example GPS).In addition, aiding sensors, for example, for measuring the speed sensor/abs sensor of operating range, and/or the gyro sensor changing for measuring vehicle angle, may be utilized to improve reliability of positioning and/or compensation satellite position error.By means of position fixing system, the current location of vehicle and driving direction can obtain.Then, position and driving direction current or that pay close attention to current or that pay close attention to are counted together with corresponding digital map data.According to numerical map, if being in, vehicle do not allow loudspeaker produce sound or do not allow sound level higher than other position of a specific order and direction, foregoing " ring loudspeaker are forbidden or limit " pattern is activated; On the other hand, according to numerical map, if vehicle is positioned at position and the direction of the necessary sounding of loudspeaker, foregoing " loudspeaker must ring " pattern is activated; Finally, if here without any loudspeaker operation regulations, chaufeur can determine operation or inoperation loudspeaker according to actual traffic situation.
Outside car, numerical map in the situation that, around the neighbouring area of current vehicle location, can from traffic control center or service supplier, to vehicle, send information by radio-type interface, then can in vehicle, determine loudspeaker operation mode.As an alternative, the current location of vehicle and direction can be sent to traffic control center or service supplier by radio-type interface.Loudspeaker operation mode can be at the definite vehicle that then sends to of traffic control center or service supplier there.
Permanent or the provisional loudspeaker operation regulations of government's issue also can be sent to traffic control center or service supplier.
Utilize numerical map, can before arriving the position of specifying, determine loudspeaker operation mode, particularly when automobile navigation is activated.
When traffic signal means of identification is used, as previously mentioned, traffic signal means of identification reads traffic signal or electronic communication sign, and then loudspeaker operation mode is set.
Be appreciated that vehicle can be by numerical map and position fixing system these two and the combination of traffic signal means of identification.
In order to control the operation of loudspeaker, can in vehicle, be equipped with horn control device.Horn control device receives signal or the information about specifying loudspeaker operation regulations, then the loudspeaker of vehicle is arranged on to corresponding operation mode.
In the position of the necessary sounding of loudspeaker, conventionally can stipulate ring loudspeaker moment and time length and sound level.On the other hand, do not allow loudspeaker to produce sound or do not allow sound level higher than other position of a specific order, conventionally can provide against or limit the period in date or every day of ring loudspeaker.These parameters also can be used to control the operation of loudspeaker.
When setting up this regulations, need to consider the balance between noise rank and traffic safety.
