DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In general, the invention relates to a technique of initiating a horn operation mode in a vehicle in responding to a signal representing a specified horn operating regulation.
The signal may be created by adopting a positing system, such as a satellite positioning system (for example, a GPS), and a digital map, and/or by adopting a traffic sign identifying device.
The horn operation mode may be such a mode in which, when the signal indicates that honking is forbidden or the sound level is not allowed to be higher than a certain level, a "honking forbidden or restriction" mode is initiated, in which the horn is deactivated, or the sound level of the horn is restricted to be under a certain level, or an alarm is created to let the driver know the forbidden or restriction condition, and when the signal indicates that honking is must to be performed, a "honking must" mode is initiated, in which the horn is activated to generate sound automatically, or an alarm is created to inform the driver to operate the horn.
The alarm may be an audio alarm or an optical/video alarm or both.
It is know that there are traffic signs indicating specified horn operating regulations arranged in those locations that have specified horn operating regulations, for example, along roads or in areas. Those signs may indicate specified points, such as a joint or an intersection of roads, specified segments, such as a distance of road or a segment of street, or specified sections, such as a living block or a government working area.
A traffic sign identifying device carried by a vehicle may capture those traffic signs and create a corresponding signal.
Electronic traffic marks may also be arranged in those locations. For example, an electric transmitter may send out a wireless signal which can be received by an electric
receiver carried a vehicle.
Additionally or alternatively, a digital map may be provided onboard, i.e., carried by a vehicle, or offboard, for example, provided in a traffic control center or a service provider. The locations that have specified horn operating regulations are combined into the map. Current location of the vehicle may be identified by a positioning system. If the digital map is provided in the traffic control center or the service provider, the vehicle is provided with a wireless interface which exchanges data with the traffic control center or the service provider.
Anyway, the vehicle may receive a signal indicating the information about the horn operating regulation at current location.
If there is not any traffic sign or regulation on horn operating regulations at a location, the vehicle at this location may have its horn working in a free mode in which the drivers may decide whether to operate the horns or not according to real traffic condition.
As the positioning system, it may be composed of at least a satellite positioning system (for example, a GPS). In addition, supplementary sensors, such as Tacho/ABS sensors for measuring traveling distances and/or Gyro sensors for measuring the angular changing of vehicles, may be incorporated for improving positioning reliability and/or compensating satellite positioning error. By means of the positioning system, current location and driving direction of the vehicle can be got. Then, current or concerned location and driving direction are taken into consideration together with corresponding data of the digital map. If, according to the digital map, the vehicle is at a location and direction that the horn is not allowed to generate sound or the sound level is not allowed to be higher than a certain level, then a "honking forbidden or restriction" mode as described above is initiated; on the contrary, if according to the digital map, the vehicle is at a location and direction that the horn must sound, then a "honking must" mode as described above is initiated; and finally, if there is not any horn operating regulation, the driver may decide to operate or not to operate the horn according to real traffic condition.
In the case of an offboard digital map, a neighboring area around current location of the vehicle can be transmitted from the traffic control center or the service provider to the vehicle via the wireless interface, and then the horn operation mode can be determined
in the vehicle. Alternatively, current location and direction of the vehicle can be transmitted to the traffic control center or the service provider via the wireless interface. The horn operation mode can be determined in the traffic control center or the service provider and sent back to the vehicle.
Permanent or temporary regulations on the operation of horns issued by the government may also be sent to the traffic control center or the service provider.
By using a digital map, horn operation modes can be set before reaching the specified locations, especially when vehicle navigation is activated.
When a traffic sign identifying device is adopted, as describe above, the traffic sign identifying device reads traffic signs or electronic traffic marks, and then a horn operation mode is set.
It can be understood that a vehicle may incorporate both the digital map and the positioning system, and the traffic sign identifying device.
For controlling the operation of the horn, a horn controlling device is provided in the vehicle. The horn controlling device receives signals or information about the specified horn operating regulations and then set the horn of the vehicle into a corresponding operation mode.
At the locations that the horns must sound, there can be generally regulations on the honking time and duration and sound level. On the other hand, at the locations that the horns are not allowed to generate sound or the sound level is not allowed to be higher than a certain level, there can be generally regulations on the forbidden or restriction dates or time periods in a day. These parameters are also adopted for controlling the operation of the horn.
When establishing such regulations, equilibrium between noise level and traffic safety should be considered.
Now some preferred embodiments of the invention will be described with reference to the drawings.
Figure 1 shows a block diagram of an automatic vehicle horn control system according to a first embodiment of the present invention. In this embodiment, the automatic horn control system comprises a control unit 1, into which programs for controlling and
configurable parameters such as languages, deactivating the horn (or mute state), lowering the sound level of the horn, etc., can be stored.
An HMI (human-machine interface) 2 is coupled to the control unit 1 for inputting parameters, setting system configuration, and outputting operation indications.
A horn 3 is connected to the control unit 1 and receives command from the control unit. The horn 3 operates in three modes, i.e., a "honking forbidden or restriction" mode, a "honking must" mode and a free mode as described above.
A positioning system 4 is coupled to the control unit 1 for providing current location and driving direction of the vehicle to the control unit.
A digital map 5 is coupled to the control unit 1 via a map interface 6. The control unit 1 fits current or concerned location and driving direction of the vehicle into the digital map and gets information about specified horn operating regulations related with this position and direction. The digital map 5 may be provided onboard or offboard. In the case of an offboard digital map, the digital map is arranged in a traffic control center or a service provider and the map interface 6 is a wireless interface.
The positioning system 4, the digital map 5 and the map interface 6 compose a horn-operating-regulation acquisition means.
In accordant with the information provided by the horn-operating-regulation acquisition means, the control unit 1 initiates a corresponding operation mode.
An automatic horn control method which may be used with the automatic horn control system of the first embodiment of the invention will be described with reference to Figure 4.
As shown in Figure 4, in step SI, a driver starts driving a vehicle.
Then, in step S2, the control unit 1 obtains current location and driving direction of the vehicle from the positioning system 4.
Then, in step S3, current location and driving direction of the vehicle are fit into the digital map and the information about specified horn operating regulations related with this position and direction is obtained.
Then, in step S4, it will judge whether honking is forbidden or restricted for current
location and direction. If the judge result of step S4 is "Yes", then the operation goes to step S41 to initiate a "honking forbidden or restriction" mode wherein the horn 3 is deactivated or the sound level of horn is lowered to be below a certain level, and/or an audio or optical/video alarming signal is sent out to let the driver know the forbidden or restriction requirement. After step S41, the operation goes to step S7 which will be described below.
On the other hand, if the judge result of step S4 is "No", then the operation goes to step
55 to judge whether it must to operate the horn to generate sound for current location and direction. If the judge result of step S5 is "Yes", then the operation goes to step S51 to initiate a "honking must" mode wherein the horn 3 is activated to generate sound and/or an audio or optical/video alarming signal is sent out to let the driver know the honking requirement. After step S51, the operation goes to step S7 which will be described below.
On the other hand, if the judge result of step S5 is "No", then the operation goes to step
56 where the operation is in a free mode in which the driver may decide whether to operate the horn according to real traffic condition
Then, the operation goes to step S7 to judge whether the driving is ended. If the judge result of step S7 is "Yes", then the operation goes to step S8 where the operation of the automatic vehicle horn control system is ended. On the other hand, if the judge result of step S7 is "No", then the operation goes back to step S2.
Figure 2 shows a block diagram of an automatic vehicle horn control system according to a second embodiment of the present invention. The second embodiment also comprises a control unit 1, an HMI (human-machine interface) 2 and a horn 3 which are similar to those disclosed in the first embodiment.
However, the automatic vehicle horn control system according to the second embodiment does not comprise the positioning system 4, the digital map 5 and the map interface 6. Instead, the automatic vehicle horn control system according to the second embodiment comprises a traffic sign identifying device 7 which reads traffic signs or electronic traffic marks and provides corresponding information to the control unit 1 which then set the horn operation mode.
The traffic sign identifying device 7 composes a horn-operating-regulation acquisition means.
Other aspects of the automatic vehicle horn control system according to the second embodiment are similar to that of the first embodiments and thus are not described.
An automatic horn control method which may be used with the automatic horn control system of the second embodiment of the invention is shown in Figure 5.
The method shown in Figure 5 is different with that shown in Figure 4 in that steps S2 and S3 are substituted with step S2' . So only step S2' will be described below.
In step S2', the traffic sign identifying device 7 reads traffic signs or electronic traffic marks and provides corresponding information to the control unit 1 which then perform the operation of step S4.
Other steps of method shown in Figure 5 are similar to that shown in Figure 4 and thus are not described.
Figure 3 shows a block diagram of an automatic vehicle horn control system according to a third embodiment of the present invention. It can be seen that the third embodiment is a combinations of the first and second embodiments. This to say, the third embodiment comprises a control unit 1, an HMI (human-machine interface) 2, a horn 3, a positioning system 4, a digital map 5, a map interface 6 and a traffic sign identifying device 7. These components are similar to those disclosed in the first and second embodiments and thus are not described.
An automatic horn control method which may be used with the automatic horn control system of the third embodiment of the invention is shown in Figure 6. It can be seen that step S2" shown in Figure 6 is a combination of steps S2 and S3 shown in Figure 4 and step S2' shown in Figure 5.
Other steps of method shown in Figure 6 are similar to that shown in Figures 4 and 5 and thus are not described.
According to the invention, at a location that honking is forbidden or restricted, the horn of a vehicle is automatically deactivated or the sound level is lowered, and/or the driver receives an alarm that the horn should not be used. Thus, horn noise will be effectively controlled in specified areas. In addition, at a location that honking must be performed, the horn of a vehicle is automatically operated to generate sound, and/or the driver receives an alarm that the horn should be operated to generate sound. Thus, traffic safety can be improved.
