Abstract
A computerized controller ensures that the tailgate of a dump truck is in a closed position, latches the tailgate to the truck bed, and locks the tailgate closed when a speed of the dump truck is at or above a selected predetermined speed. The system implements two complementary functions: Tailgate Latch and Lock (TLL) and Tailgate Closed Assurance (TCA). The TLL function monitors the dump truck speed, and automatically latches the tailgate when the dump truck exceeds a selected predetermined speed. The TLL function will not release the tailgate latch until the dump truck is moving below the selected predetermined speed, regardless of operator input. In implementation, the TLL function relies on TCA. The TCA function ensures that the tailgate is in a fully closed position prior to the TLL actuating the tailgate latch, thus eliminating the possibility of “false positive” TLL actuation if the latch is fouled with debris.
