Definitions

  • the present invention relates to a vehicle turn indicator system especially but not exclusively for commercial vehicles.
  • the present invention is directed to a turn indicator system for a vehicle which comprises four or more flashing visual indicators, one or more audible indicators, such that at least two visual indicators are on each side of the vehicle, and the one or more audible indicators emit(s) sound selected from at least one of broadband sound, white sound ® or noise, pink sound or noise and multi-frequency sound, and a cut out which upon engagement stops operation of the audible indicator or indicators, in which the visual and the audible indicators operate at the same time, such that when the vehicle is in motion upon operation of the indicator system the visual and the audible indicators emit their warning signals at the same time.
  • the visual and audible indicators emit their warning signals synchronously or simultaneously.
  • the cut out can be acted upon by a vehicle speed monitor which stops operation of the audible indicator or indicators when no motion in occurring or when the vehicle speed exceeds a predetermined speed.
  • a vehicle speed monitor which stops operation of the audible indicator or indicators when no motion in occurring or when the vehicle speed exceeds a predetermined speed.
  • the cut-out can be operated at predetermined times which are for instance deemed anti-social.
  • At least one of the audible indicators is placed on the near side, off side, blind side or rear of the vehicle. This has the advantage that the audible indicator is installed where driver-visibility difficulties are most acute.
  • at least one audible indicator on each side of the vehicle is at least one audible indicator on each side of the vehicle.
  • the sound emitted is in the human audible hearing range, preferably 50 Hz to 6 kHz, and in an especially preferred embodiment 50 Hz to 4 kHz.
  • the frequency range is such that it does not necessarily enhance the locatability of the sound which depends on the sound’s frequency spectrum and number of frequencies that are emitted at the same time or richness of the sound. Also in higher frequency ranges the ability of older people to hear is reduced. This is discussed in the Brigade White Paper of March 2009, whose contents are imported.
  • the audible warning can in addition include voice instructions which can vary depending on the side of the vehicle concerned, local language and driving position on the road.
  • the turn indicator system can have a country selector included with it to enable appropriate audible warnings and voice commands.
  • the visual indicator and the audible indicator are a single unit and can be fitted to a vehicle as one unit. This provides the advantage that the indicator system can be fitted simply.
  • the audible indicator is powered by a source independent to that of the visual indicator. This provides the advantage that such an indicator system can be retrofitted readily to most commercial vehicles as current commercial vehicles have circuits which indicate to the driver that an indicator light is not working. If the audible indicator takes power from the fitted indicator system it is likely that the existing vehicle safety system will misinform the driver that the relevant visual indicator is not working.
  • each visual indicator has a locatable audible indicator associated with it. This helps draw the cyclist’s attention to the visual indicator.
  • a vehicle is equipped with one or more visual and audible indicators down each side in addition to those at each corner. This provides the advantage that a cyclist proceeding down the side of a particularly long vehicle will see the indicators more readily as they are closer.
  • broadband sound white sound® or noise, pink sound or noise or multi-frequency sound means that the propagation of the sound is limited to an area round the vehicle and does not provide nuisance in a built-up area. Furthermore it means that a cyclist will not be distracted by other vehicles equipped with a similar system.
  • the indicator system is equipped with a selector such that if the hazard lights are switched on the audible indicators can be selected on one or other side or on both sides of the vehicle. This provides the advantage that attention can be drawn to a stopped vehicle.
  • the audible indicator is linked directly to or through the cut-out switch to an object detection system so that the audible indicator is only operational or is operational at a lower sound level except when an object or person is detected in the hazard zone.
  • This minimises the emission of sound and potential noise nuisance.
  • one or more sensors or cameras are positioned along the side of the vehicle such that they can detect objects in the danger zone alongside the vehicle. The width and length of the detection zone may be varied depending on the capability of the detection technology used (ultrasonic, radar or camera image processing) and the perceived area of danger.
  • the detection system On detecting a target for example a cyclist the detection system transmits a signal via high or low voltage trigger wire or CAN message. This signal is used as an input to the audible indicator. For example as the inverse of the cutout activation. Such that when there is no detection the cutout is ON and where there is detection the cutout is off.

  • the vehicle 20 is equipped with a front driver’s side visual indicator or direction-lamp indicator 22 and a rear offside visual indicator 26 at the rear of the trailer and a front offside visual indicator 24.
  • the rear driver’s side visual indicator is not shown.
  • the cab 28 of the articulated vehicle is equipped with visual indicators 30 at its rear, in this case only the offside visual indicator 30 is shown.
  • the vehicle 20 is equipped with two additional side visual indicators 32 on the trailer 34.
  • the vehicle 20 in this case is equipped with audible indicators on each side. These can be placed directly in association with the visual indicators 22, 24, 26, 30, 32 or alternatively with just one on each side.

  • Figure 3 shows a plan view of a vehicle 40.
  • the vehicle 40 is equipped with four visual indicators 42 at each corner.
  • the vehicle 40 is also equipped with side visual indicators 44 and 46.
  • the vehicle 40 is articulated as indicated by the dotted line 48, there is a separation of cab and trailer and the indicators 44 are placed on the rear of the cab.
  • a cyclist 50 is seen alongside the vehicle offside. Cyclist 50 is making its way along the side of vehicle between the side of the vehicle 52 and the road edge 54. In reality the distance between vehicle side 52 and the edge of the road 54 can be quite narrow. Thus as can be seen in such cases it may not be easy for the cyclist 50 to see the indicators 42. Furthermore depending upon the position of the cyclist 50 the visibility of the indicators 44 and 46 may be low. Therefore audible indicators in association with any of the visual indicators would draw the attention of the cyclist to the visual indicators 42, 44, 46.
  • Figure 4 shows a block diagram of an indicator system 60 according to the present invention.
  • a left turn visual indicator input 62 and a right turn visual indicator input 64 are connected to the system 60. These inputs 62, 64 are initiated by the vehicle driver selecting a left or right turn indicator.
  • a vehicle speed signal 66 and a cut out input 68 are connected to the indicator system 60.
  • the cut out input 68 is a driver or timer operated cut out which stops the transmission of the left or right turn indicator input by the system 60 to the audible alarms when for instance operating in hours deemed to be anti social i.e. between 23:00 and 07:00.
  • the indicator system 60 is connected to a left turn audible output 72 connected to an audible indicator 72 and a right turn alarm output 74 connected to a right turn audible indicator 76.
  • the indicator system 60 is connected independently to the vehicle 12/24 volt power supply by connection 78.
  • the indicator system 60 is also attached to the vehicle ground 80.
  • the vehicle speed signal 66 connected to the indicator system 60 which has a predetermined threshold speed set. Above the selected speed, the indicator system 60 will switch a transmission switch from an “off” state to an “open” state allowing output to the audible indicators 72, 76.
  • the left turn visual indicator input 62 When the left turn visual indicator input 62 is active the left turn audible indicator 72 will sound in sync with the left turn indicator input 62.
  • the right turn visual indicator input 64 is active the right turn audible indicator 76 will sound in sync with the right turn indicator input 64. In all other states the outputs 70, 74 are off.
  • Figure 5 shows the operational logic for the indicator system. As can be seen if the vehicle speed is not sufficient then the audible indicators do not operate. This ensures that if the vehicle is stationary and the indicators are operating then no sound is emitted. As is obvious if a vehicle is stopped then it is unlikely to be a danger to a cyclist and furthermore this reduces noise pollution. It also ensures if the hazard lights are selected when the vehicle is stationary then the audible indicators do not work. Furthermore the cut-out input can stop output of the audible indicators during anti-social hours.
  • FIG. 6 shows a block diagram of a further indicator system 160 according to the present invention.
  • An A indicator input 162 and a B indicator input 164 are connected to the system 160. These inputs 162, 164 are initiated by the vehicle driver selecting a left or right turn indicator thus also initiating the relevant visual indicators.
  • a vehicle speed signal input can be optionally connected to the indicator system 160.
  • a latched mute input 166 is connected to the system 160 and is a driver operated cut out which stops the transmission of the A or B indicator input by the system 160 to the audible alarm when desired.
  • a timed mute input 168 is connected to the system 160 and is a timer operated cut out which stops the transmission of the A or B indicator input by the system 160 to the audible alarm when for instance operating in hours deemed to be anti social i.e. between 23:00 and 07:00.
  • the timed mute input 168 has a predetermined mute period, in this case four minutes after which it operates in order to provide warning as necessary.
  • the mute inputs 166, 168 are reset when vehicle is turned off and on.
  • the indicator system 160 contains a single audible output 172.

  • the indicator system 160 is also attached to a vehicle ground 180.

When the B indicator input 164 is active the audible indicator 172 will sound in sync with the B indicator input 164. In all other states the audible indicator 172 is off.
  • Figure 7 shows the operational logic for the indicator system 160. As can be seen if the A or B indicators are operating then the audible warning is on. However if both indicators are off or are both operating then the audible indicator is off. This ensures that if the vehicle indicators are off or the hazard lights are selected then the audible indicator does not work.

  • the sensors can be grouped together using a common ECU or ECUs to analyse their signals. If a target is detected within this zone each sensor will send a signal to the ECU and the ECU will signal this to the audible device by changing the voltage on a trigger wire.
