Description:A METHOD AND A SYSTEM FOR ADJUSTING ANTENNA TO REDUCE WIND-CUT NOISE IN A VEHICLE
TECHNICAL FIELD
[0001] The present disclosure relates, generally, to a method and a system for adjusting antenna of a vehicle. The present disclosure, in particular, relates to a method and a system for adjusting antenna to reduce wind cut noise in a vehicle.
BACKGROUND
[0002] In the vehicles, an infotainment system is provided which is a unified hardware interface for the systems including screen, buttons and system controls for numerous integrated information and entertainment function. One of the entertainment function of the infotainment system includes AM/FM radio. Car antenna is an automotive accessory that can provide an uninterrupted transmission of wireless signals and radio waves. Thus, it is quintessential that the antenna in the car is adjusted properly for proper working of the AM/FM radio in the vehicle.
[0003] Antennas are traditionally disposed on the exterior of the vehicle. Monopole rod antennas are usually used for best AM/FM reception in the vehicles. Length and angle of the antenna are based on the frequency band of AM/FM radio. For instance, for FM frequency band of 88 MHz to 108 MHz requires antenna having approximately length of 750 mm. However, various instances, such as daily parking need, underpass, high speed driving and high mileage require length and angle of the antenna to be changed as per the need.
[0004] A close loop control unit is provided in the antenna to adjust antenna length and angle for better reception. Generally, the antenna receives signal which is utilized by infotainment system/ audio system. An in-built tuner IC is provided to measure signal to noise ratio. The signal to noise ratio is a parameter used to define the quality of received signal. Thus, control unit is adapted to change the length and angle of the antenna for better reception when the signal to noise ratio is below predefined threshold.
[0005] In addition, a radar sensor could be provided on the tip of the antenna rod which can detect low underpass or parking entrances. This radar sensor could be used in tandem with the control unit to change the length and angle of the antenna to avoid any damage to the antenna.
[0006] In addition to the problem of bad reception of signal, underpass and parking entrance, one other problem related to antenna exists, namely, wind cut noise generated by the antenna when the vehicle is travelling at high speed. At high speed, the antenna generates high wind cut noise in cabin of the vehicle. The generation of wind cut noise deteriorates NVH performance of the vehicle and cause unease to the passengers and driver of the vehicle.
[0007] Accordingly, there is a need for a method and a system for adjusting the antenna to reduce wind cut noise in the vehicle.

[0034] The present disclosure provides a method and a system for adjusting antenna to reduce wind cut noise in a vehicle.
[0035] FIG. 1 illustrates an exemplary system 100 for adjusting antenna that can be utilized to implement one or more exemplary embodiments of the present disclosure. The system 100 become functional when the user has chosen radio as entertainment function on infotainment system 106 or the user has switched on the audio unit 106 (such as radio). The system 100 comprises a controller 101, a memory 101a, a noise cancellation microphone 102 and a control unit 105. The noise cancellation microphone 102 is provided in cabin of the vehicle to determine wind-cut noise level. In an aspect, the noise cancellation microphone 102 is positioned above the head of the driver on roof inside the vehicle. However, the noise cancellation microphone 102 can be positioned at any other position inside the vehicle. The noise cancellation microphone 102 is adapted to determine wind cut noise level and ignoring any other noise created by passengers or the driver. This makes the system 100 more accurate and eliminate any possibility of adjustment of the antenna 107 where the adjustment is not required.
[0036] The control unit 105 is provided to adjust the length and angle of the antenna 107. The control unit 105 is operatively connected to the controller 101. The controller 101 is adapted to determine adjusting parameters to adjust the antenna 107 to reduce the wind cut noise in the cabin of the vehicle. The operating parameters are sent to the controller 101 in the form of signals. The controller 101 needs some operating parameters to accurately determine the adjusting parameters. For instance, it is necessary to take into account the possibility of the noise cancellation microphone 102 catching some noises which are not resulting from wind cut noise generated by the antenna 107. To eliminate such possibilities, the system 100 is designed to operate only when the doors and windows of the vehicles are closed. This eliminates outside noises entering into the cabin of the vehicle. The controller 101 is configured to receive a first parameter signal and a second parameter signal. The first parameter corresponds to state of doors of the vehicle. The second parameter corresponds to state of windows of the vehicle. The state of the doors and windows of the vehicle is determined by a display audio/ speedometer 104. The display audio/ speedometer is configured to transmit a first parameter signal and a second parameter signal confirming all the doors and windows of the vehicle are closed.
[0037] In addition, it is necessary to take into account the situation where the noise in the cabin is due to some other factors not including wind cut noise generated by the antenna 107. To eliminate such possibilities, the system 100 is designed to operate only when speed of the vehicle is above a predefined limit for a predefined period of time. This eliminate taking into account any noises other than the wind cut noise generated by the antenna 107. The controller 101 is configured to receive a third parameter signal. The third parameter corresponds to speed of the vehicle. The speed of the vehicle is determined by a BCM 103/ speedometer 104. The BCM 103/ speedometer 104 is configured to transmit a third parameter signal when speed of the vehicle is above a predefined limit for a predefined period of time.
[0038] After receiving the first parameter signal, the second parameter signal, the third parameter signal and the real time wind cut noise level in cabin of the vehicle, the controller 101 is configured to compare the received real time wind cut noise level in the cabin of the vehicle with a predefined threshold value stored in memory 101a of the vehicle operatively connected to the controller 101. This comparison is performed only when the wind cut noise is more than a predefined limit for a predefined period of time. Further, the predefined threshold value depends on the predefined requirement set by OEM (Original Equipment Manufacturer).
[0039] Based on the comparison, by the controller 101, the controller 101 is further configured to determine adjustment parameters for the antenna 107. The determination of adjustment parameters is only performed by the controller 101 when the compared real time wind cut noise signal is more than predefined threshold value stored in the memory 101a. The adjustment parameters include length and angle for the antenna 107. Since the system 100 become functional when the user has chosen radio as entertainment function on infotainment system 106 or the user has switched on the audio unit (such as radio), the adjustment parameters i.e. the length and angle of the antenna 107 is determined keeping into consideration the AM/FM reception for operation of the radio 106. Further, the adjustment parameters are determined based on pre-set mappings stored in the memory 101a operatively connected to the controller 101. The pre-set mapping stored in the memory 101a includes a wind cut noise and length of antenna 107 mapping and a wind cut noise and angle of antenna 107 mapping. Through the determined real-time wind cut noise level, the corresponding length and angle of the antenna 107 at such real-time wind cut noise level in the mappings are determined. These length and angle of the antenna 107 are the adjusting parameters at that real-time wind cut noise level.
[0040] The controller 101 after determining the adjustment parameters transmit the determined adjustment parameters to the control unit 105. The control unit 105 is adapted to adjust the length and angle of the antenna 107 based on the determined adjustment parameters.
[0041] However, before transmitting the adjustment parameters, the controller 101, send a request signal to the infotainment unit 106 suggesting to switch OFF the radio or change the multimedia source from radio to other source. The user can switch OFF the radio or change the multimedia source from radio to other source instead of adjustment of the antenna 107. In addition, an override feature is also available wherein the user can manually direct the control unit 105 to adjust length and angle of the antenna to reduce wind cut noise.
[0042] FIG. 2 illustrates a flow chart of the method 200 for adjusting antenna to reduce wind cut noise in a vehicle that can be utilized to implement one or more exemplary embodiments of the present disclosure. The method 200 is implemented on the system 100 discussed with reference to FIG. 1.
[0043] At block 202, the method 200 includes receiving real-time wind cut noise level in cabin of the vehicle. The real-time wind cut noise level is received on the controller 101. The wind cut noise level is determined by noise cancellation microphone 102. The noise cancellation microphone 102 is adapted to determine wind cut noise level and ignoring any other noise created by passengers or the driver. This makes the method 200 more accurate and eliminate any possibility of adjustment of the antenna 107 where the adjustment is not required. The determined wind cut noise level in the cabin of the vehicle is transmitted to the controller 101 in real time.
[0044] At block 204, the method 200 includes receiving a first parameter signal confirming all the doors of the vehicles are closed. The first parameter signal is received on the controller 101. The first parameter corresponds to state of doors of the vehicle. The state of the doors of the vehicle is determined by the display audio/ speedometer 104. The display audio/ speedometer 104 is configured to transmit the first parameter signal when all the doors of the vehicles are closed.
[0045] At block 206, the method 200 includes receiving a second parameter signal confirming all the windows of the vehicles are closed. The second parameter signal is received on the controller 101. The second parameter corresponds to state of windows of the vehicle. The state of the windows of the vehicle is determined by the display audio/ speedometer 104. The display audio/ speedometer 104 is configured to transmit the second parameter signal when all the windows of the vehicles are closed.
[0046] At block 208, the method 200 includes receiving a third parameter confirming speed of the vehicle is above a predefined limit for a predefined period of time. The controller 101 is configured to receive the third parameter signal. The third parameter corresponds to speed of the vehicle. The speed of the vehicle is determined by the BCM 103/ speedometer 104.
[0047] At block 210, the method 200 includes comparing real-time wind cut noise level in the cabin of the vehicle with a predefined threshold value stored in memory 101a operatively connected to the controller 101 when the wind cut noise is more than a predefined limit for a predefined period of time after receiving the first parameter signal, the second parameter signal and the third parameter signal.
[0048] At block 212, the method 200 includes determining adjusting parameters for the antenna 107 based on pre-set mappings stored in the memory 101a operatively connected to the controller 101 when the real-time wind cut noise level in the cabin is more than the predefined threshold value. The adjustment parameters include length and angle of the antenna 107. Since the method 200 become functional when the user has chosen radio 106 as entertainment function on infotainment system 106 or the user has switched on the audio unit (such as radio 106), the adjustment parameters i.e. the length and angle of the antenna 107 is determined keeping into consideration the AM/FM reception for operation of the radio 106. Further, the adjustment parameters are determined based on pre-set mappings stored in the memory 101a operatively connected to the controller 101. The pre-set mapping stored in the memory includes a wind cut noise and length of antenna mapping and a wind cut noise and angle of antenna mapping. Through the determined real-time wind cut noise level, the corresponding length and angle of the antenna 107 at such real-time wind cut noise level in the mappings are determined. These length and angle of the antenna are the adjusting parameters at that real-time wind cut noise level.
[0049] At block 214, the method 200 includes transmitting the determined adjusting parameters to adjust the antenna 107 to reduce the wind cut noise in the cabin of the vehicle. The determined adjusting parameters are transmitted to the control unit 105. The control unit 105 is adapted to adjust the length and angle of the antenna 107 based on the determined adjustment parameters.
[0050] Figure 1 already discussed the features of the components of the system 100 used to implement the method 200. The method 200 works in the same way as already disclosed for the system 100.
WORKING OF THE SYSTEM AND THE METHOD
[0051] FIG. 3 illustrates a flow chart of the system 100 and method 200 for adjusting antenna to reduce wind cut noise in a vehicle that can be utilized to implement one or more exemplary embodiments of the present disclosure. The need for determining adjusting parameters only exist when the user has chosen AM/FM radio as multimedia source or AM/FM radio as entertainment function on the infotainment system 106. In case, the user is not listening to AM/FM radio, there is no need to determine adjustment parameters for the antenna 107 for reception of AM/FM signal to operate AM/FM radio. If wind cut noise exists in this scenario, the user can adjust the length and angle of the antenna 107 as per the need to reduce wind cut noise level in the cabin of the vehicle.
[0052] The present system 100 and method 200 comes into operation when the user has chosen AM/FM radio 106 as multimedia source or AM/FM radio as entertainment function on the infotainment system 106. The noise cancellation microphone 102 detects real time wind cut noise level inside the cabin of the vehicle. The real time wind cut noise level is transmitted to the controller 101 in real time. In addition, the first parameter signal, the second parameter signal and the third parameter signal are received by the controller 101 confirming that all the doors and windows of the vehicle are closed and speed of the vehicle is more than a predefined limit for a predefined period of time. Only after receiving the first parameter signal, the second parameter signal and the third parameter signal and the real time wind cut noise being more than predefined limit for a predefined period of time, the controller 101 compare the received real time wind cut noise level in the cabin of the vehicle with a predefined threshold value stored in the memory 101a. When the real-time wind cut noise level in the cabin is more than the predefined threshold value, the controller 101 determines the adjusting parameters for the antenna based on preset mappings stored in the memory operatively connected to the controller 101. The controller 101 sends a request signal to the infotainment system 106 suggesting to switch OFF the radio or change the multimedia source from radio to other source. The user can switch OFF the radio or change the multimedia source from radio to other source instead of adjustment of the antenna 107. In addition, an override feature is also available wherein the user can manually direct the control unit 105 to adjust length and angle of the antenna 107 to reduce wind cut noise. In case user does not choose override feature, the determined adjusting parameters are than transmitted to the control unit 105 which is capable of adjusting the length and angle of the antenna 107 based on the received adjustment parameters.
