CYCLIST WARNING SYSTEM

摘要

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.

主权项

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.
