ABSTRACT:
A communications device to foster the correct steering of a vehicle by a driver who cannot see where the vehicle is moving with respect to its surroundings, including a control box which is handled by a remote observer, and an indicator panel having at least three lights thereon, with the control box and the indicator panel being connected by appropriate electrical conductors. The control box has one or more switches which generate nine basic signals to indicate to the vehicle driver what he should do, including such signals as turn his steering wheel to the left or to the right, or that he should either move forward, backward or stop the vehicle. The preferred embodiment includes a single control knob on the control box which is moved by the observer in the direction that the vehicle should move. The signal knob is biased to be in a centered position, and movement of the knob either forward or rearward, or to one side or the other, will cause an appropriate signal to be generated which is displayed in front of the driver on his indicator panel. When the device is activated, it has an initial rest position in which the signal displayed in front of the driver is "stop"; all movement instructions from the observer must over-ride the stop signal. Hence, the unit is fail-safe in that any interruption of signals being generated by the observer's control box due to a malfunction will cause a stop signal to appear in front of the vehicle driver. The device can also be used to give instructions to a driver who is attempting to back a vehicle and trailer, by reversing the manner in which the indicator lights are activated.
