ABSTRACT:
An automatic adjustment system for maintaining a line of sight between a driver and a rear end of a trailer towed by a tow vehicle is disclosed. A transmitter and a receiver are coupled proximal a side-view mirror. A reflector is mounted proximal the rear end of the trailer and is adapted to receive a signal from the transmitter and to reflect the signal to the receiver. A control unit is provided for determining a deviation from an initial value of a selected property of the signal, the initial value corresponding to an orientation of the mirror when the line of sight is established. An actuator responsive to the controller orients the mirror such that the value of the selected property of the signal is returned to the initial value.
