Abstract

A warning system for trucks includes visual and audible warning devices (12,13) at the nearside, and linked to the vehicle turning indicator. Such a system may reduce collisions with cyclists. One or more proximity sensors (34-36) may detect a cyclist at the nearside, and give an in-cab warning to the vehicle driver.

Claims

1. A warning system for the nearside of a vehicle and comprising a controller for a vehicle cab and one or more warning devices responsive to said controller for providing a visual and/or audible warning at the nearside of said vehicle, said controller being automatically triggered by operation of a vehicle nearside turn indicator, said warning system further including a plurality of proximity sensors for sensing a cycle at the nearside of a vehicle, said plurality of proximity sensors communicating with said controller, said controller being adapted to discriminate signals from the plurality of proximity sensors to detect movement of a cycle relative to a vehicle to which said sensors are mounted, said discrimination using the relative forward movement of the cycle by detecting successive inputs from a rearmost sensor to a front most sensor of the plurality of proximity sensors and eliminating stationary objects using a relative speed threshold.

2. The system of claim 1, wherein said visual and audible warning devices are combined in a common housing.

3. The system of claim 1, wherein the visual warning device is circular and comprises a plurality of LEDs in the shape of a cycle, said LEDs being illuminated upon triggering of said controller.

4. The system of claim 3, wherein the visual warning device further includes a warning sign comprising a plurality of LEDs in the form of a circle and oblique slash crossing the circle.

5. The system of claim 4, wherein the LEDs associated with the warning sign are adapted for illumination independently of the LEDs associated with the cycle.

6. The system of claim 5, wherein LEDs associated with wheels of the cycle are adapted for illumination independently of the LEDs associated with the frame of the cycle.

7. The system of claim 1, and further including an ambient light inhibit whereby operation of said one or more warning device is inhibited below a pre-determined level of ambient light.

8. The system of claim 7, further comprising an ambient light sensor incorporated in one or more of said warning devices and in communication with said controller.

9. The system of claim 1 wherein said controller includes a warning sounder for a vehicle driver.

11. The system of claim 9, wherein said controller is adapted to enable said one or more warning devices and said one or more proximity sensors independently

19. The system of claim 1, and further including a mute control associated with said controller.

20. The system of claim 1, and further including a vehicle speed inhibit whereby operation of said one or more warning devices is inhibited above a pre-determined vehicle road speed.

21. A vehicle incorporating the warning system of claim 1.

10. (canceled)

12. A driver warning system for a vehicle comprising a controller for a vehicle cab, a device responsive to said controller for providing a warning in said cab and a plurality of proximity sensors for sensing a cyclist at the nearside of the vehicle, said plurality of sensors communicating with said controller via signals, and said controller being adapted to discriminate said signals to activate said warning device upon detection of a cyclist relative to the vehicle, said discrimination using the relative forward movement of the cycle by detecting successive inputs from a rearmost sensor to a front most sensor of the plurality of proximity sensors and eliminating stationary objects using a relative speed threshold.

13. The system of claim 12, wherein said warning is audible and/or visual.

14. The system of claim 12, wherein said controller is triggered by operation of a vehicle nearside turn indicator.

15. The system of claim 12, and further including a mute control associated with said controller.

16. The system of claim 12, and further including a vehicle speed inhibit whereby operation of said one or more warning devices is inhibited above a pre-determined vehicle road speed.

17. A vehicle incorporating the warning system of claim 12.

18. (canceled)
