Wireless signal apparatus for assisting drivers to back large vehicles
First Claim
1. A back-up safety apparatus that enables a driver of a vehicle to receive indications from a spotter positioned outside of the vehicle in a position that provides the spotter with a view of one or more blind spots of the driver positioned in a driver seat of the vehicle, the apparatus comprising:
- a handheld wireless transmitter configured for control by the spotter, the handheld wireless transmitter comprising a button having only two positions, wherein the handheld wireless transmitter is configured to transmit a first wireless signal only when the button is depressed by the spotter so that the button is in a first position;
a wireless receiver configured to be positioned on the vehicle that is capable of detecting reception of the first wireless signal that is transmitted from the handheld wireless transmitter; and
a first signal device configured to be positioned on the vehicle such that the driver of the vehicle can see and/or hear the first signal device when the driver is operating the vehicle, wherein the first signal device is configured to provide a first audio and/or visual indication indicating that the driver is clear to back-up the vehicle in response to the wireless receiver receiving the first wireless signal, and wherein the first signal device is configured to provide a second audio and/or visual indication indicating that the driver is not clear to back-up the vehicle in response to the wireless receiver not receiving the first wireless signal when the button is in the second position.

Abstract
A back-up safety apparatus and method that enables the driver of a large vehicle with inherent rear blind spots to receive signals, to proceed or stop, based on changing safe or unsafe conditions. A spotter who monitors the vehicle'"'"'s progress from a safe and remote vantage point in the rear, uses a hand held wireless transmitter to signal the driver. The transmitter also provides a deadman style safety switch for the benefit of the spotter that will automatically signal the driver to stop if the spotter becomes disabled, falls or drops the transmitter.

17. A method of signaling a driver of a vehicle of a spotter'"'"'s indications regarding backing of the vehicle, wherein the driver is positioned to drive the vehicle at least in reverse and the spotter is positioned outside of the vehicle in a position to view at least a portion of an intended backing path to be taken by the vehicle, the method comprising:
-
emitting a first signal from an indicator positioned on the vehicle such that the first signal is perceivable by the driver, the first signal indicating that the driver should not move the vehicle; in response to receiving a first wireless signal from a handheld transmitter held by the spotter, emitting a second signal from the indicator, the second signal indicating that the driver may move the vehicle, wherein the handheld transmitter does not include a mechanism for providing indications of steering directions; and in response to not receiving the first wireless signal, after having received the first wireless signal, emitting the first signal from the indicator indicating that the driver should not move the vehicle. - View Dependent Claims (18, 19, 20, 21)
