ABSTRACT:
Automatic Trailer Control System--containing four principle inventions. One part of the invention provides automatic trailer steering control to the trailer to cause a delayed turn of the trailer steering mechanism while maneuvering a turn. A second part of the invention provides an electro-magnetic braking system, to the trailer, which is controlled by the same Microcomputer system that controls the trailer turning. The third part of the invention utilizes the electro-magnetic braking system as an alternator/generator to be used as an auxiliary battery charging system. A fourth part of the invention uses the electro-magnetic braking system as a motor to drive the trailer wheels as an assist during trucking operations. All operational functions are controlled by the Microcontroller based control system mounted on the trailer rear wheel platform. Sensors are placed on the truck/trailer operating system to obtain operational information needed for the control of the system.
