Abstract
A device for controlling a directional motion indicator includes a motion detector transmitting a directional motion signal based on a movement and a direction of the movement of the motion detector. A controller includes a controller input port receiving the directional motion signal. The controller determines a backward movement of the motion detector based on the directional motion signal. The controller transmits a motion indicator signal, via a controller output port, based on the determined backward movement of the motion detector.
Claims28
A device for controlling a directional motion indicator, the device comprising:
- a motion detector transmitting a directional motion signal based on a movement and a direction of the movement of the motion detector;
- and
- a controller including a controller input port receiving the directional motion signal, the controller determining a backward movement of the motion detector based on the directional motion signal indicating a motion vector having a motion vector component extending away from a rear side of the motion detector and transmitting a motion indicator signal, via a controller output port, based on the determined backward movement of the motion detector.
(canceled)
A vehicle trailer backup warning system, comprising:
- a motion detector transmitting a directional motion signal based on a movement and a direction of the movement of the motion detector;
- a controller including a controller input port receiving the directional motion signal, the controller determining a backward movement of the motion detector based on the directional motion signal indicating a motion vector having a motion vector component extending away from a rear side of the motion detector and transmitting a motion indicator signal, via a controller output port, based on the determined backward movement of the motion detector;
- and
- a directional motion indicator activated based on the transmitted motion indicator signal.
A method for activating a vehicle trailer directional motion indicator, the method comprising:
- transmitting a directional motion signal based on a movement and a direction of the movement of a motion detector on an associated vehicle trailer;
- receiving the directional motion signal;
- determining a backward movement of the vehicle trailer based on the directional motion signal indicating a motion vector having a motion vector component extending away from an identified rear side of the motion detector;
- transmitting a motion indicator signal based on the determined backward movement of the vehicle trailer;
- and
- activating the directional motion indicator based on the motion indicator signal.
