1. A control system for automatic adjustment of a rearview mirror of a vehicle, said system comprising:
- a motor vehicle pivotally coupled at a rearward end thereof to a forward end of a trailer,a rearview mirror mounted on a drive unit on a first side of said motor vehicle, a wireless signal transmitter mounted on a corresponding first side of said trailer adjacent to the rearward end of said trailer, and a wireless signal receiver for receiving a signal beam transmitted by said transmitter when mounted on said motor vehicle in preselected spatial relationship with said mirror, a horizontal angular position of said mirror being changed by said drive unit in response to a preselected change in the mutual angular position between said motor vehicle and said trailer, and said mutual angular position change being detected as a variation, said variation being between no signal when said motor vehicle is straight ahead of said trailer wherein said signal beam angularly passes said receiver and a signal received by said receiver from said transmitter when said motor vehicle is turned to said first side of said trailer wherein said signal beam hits said receiver.

7. A control system for automatic, turn-responsive adjustment of a rearview mirror of a vehicle, said system comprising:
-
a motor vehicle pivotally coupled at a rearward end thereof to a forward end of a trailer, a drive unit mounted on a first side of said motor vehicle a rearview mirror on said drive unit for adjustment of a horizontal angular position of said rearview mirror by said drive unit; a wireless signal transmitter mounted on a corresponding first side of said trailer adjacent to the rearward end of said trailer, said wireless signal transmitter transmitting a signal beam at a horizontal angle from said first side of said trailer toward said forward end of said trailer when so mounted; a wireless signal receiver for receiving said signal beam and causing said drive unit to adjust said horizontal angular position of said rearview mirror in response to receiving said signal beam; and mounting means for mounting said wireless signal receiver on said first side of said motor vehicle in a position for said wireless signal receiver to receive said signal beam only when said motor vehicle has turned sufficiently toward said first side thereof relative to said trailer.
