Automated angulating mirror

Claim 1

An actuating device for automatically controlling the position of a movable mounted mirror in response to a relative positioning of the vehicle with respect to a trailer pivotably mounted to the vehicle about and axis, said device comprising; mirror actuating means comprising a motor and means for powering hydraulic fluid from a reservoir; a hydraulic actuated electrical piston and cylinder arrangement, said piston being directly connected to said mirror; a first electric power source for powering said motor; a check valve in direct hydraulic connection to said reservoir; a first solenoid valve in direct hydraulic connection to said hydraulic actuated electrical cylinder; said first solenoid valve for directional flow control of said hydraulic fluid between said reservoir and said hydraulic actuated electrical cylinder; a first switching means for opening said first solenoid valve and for closing said check valve and causing flow of said hydraulic fluid to said hydraulic actuated electrical cylinder whereby said piston is moved to directly move said mirror; a second switching means for closing said first solenoid valve, causing said hydraulic fluid to open said check valve to return hydraulic fluid to said reservoir; a third switching means for opening a second solenoid valve, releasing said hydraulic fluid from said hydraulic actuated electrical cylinder to said reservoir; a fourth switching means for closing said second solenoid valve; a second electrical power source for said first, second, third and fourth switching means; and a circuit board for controlling current between all said switching means and said first and said second solenoid valves.
