Abstract: A method for controlling a vehicle system includes receiving, at a control system, a request to open an ambient air inlet valve of a vehicle component, wherein the ambient air inlet valve is operable to move from a closed position to an open position in response to an open signal that is transmitted to the ambient air inlet valve from the control system. The method also includes determining whether a towing condition is present, determining whether at least one submergence risk criterion is present, and transmitting the open signal to the ambient air inlet valve, in response to the request to open the ambient air inlet valve, if the towing condition is not present or the at least one submergence risk criterion is not present.

Abstract: To test whether a trailer is coupled to a tractor when the tractor ignition switch is off, a test switch in the trailer connects a high-impedance power source in a trailer to a line carrying energy from the tractor ignition switch to the trailer's electrical load, and measures the voltage at the line. A high voltage indicates a connection only to the electrical load in the trailer and thus a decouple. A low voltage indicates a measurement of the electrical loads in both trailer and tractor and hence a coupling.

Abstract: An electronic system that includes a trailer sensor, a lock sensor and a control circuit determine whether a trailer hitch assembly is properly coupled to a trailer. The trailer sensor senses the position of the trailer relative to the trailer hitch assembly and the lock sensor senses the position of the locking mechanism. The control circuit is coupled to the trailer sensor and the lock sensor and masks an output of the lock sensor for a first predetermined stabilization period after the control circuit initially determines that the trailer hitch assembly is properly coupled to the trailer.

Abstract: An anti-jackknife system for use while towing a trailer with a tractor. The tractor and trailer are coupled to each other by a fifth-wheel assembly in known manner. The fifth-wheel assembly includes a wheel plate carried by the tractor and a cooperating pin carried by the trailer, the pin being rotatable within the wheel plate when the tractor and trailer are coupled to each other. First and second abutments are carried by the trailer on opposing sides of the pin. The abutments move in paths around the pin on a change in orientation between the tractor and trailer, as during turning, for example. Fluid-actuated cylinders are carried by the tractor on opposing sides of the wheel plate with each cylinder providing a stop movable between a first position out of the abutment path. The stops are normally in the second position. A jackknife condition is detected to actuate at least one of the fluid-actuated cylinders to move its associated stop into the first position. In a preferred embodiment, a back-up state of the tractor disables movement to the fluid-actuated cylinders while a steering motion selectively disables one of the cylinders.

Abstract: A trailer hitch structure for coupling a double caster-type wheel trailer to a tow vehicle having a conventional hitch bar fixed thereto and projecting rearwardly thereof. There is provided a rigid vehicle connector having a front portion fixedly connectable to the hitch bar. The front portion connects to a transversely extending rear portion which extends generally parallel to the vehicle bumper. This rear portion mounts adjustable bumper elements adjacent the opposite ends thereof, which bumper elements adjust for snug engagement with the vehicle bumper. A crossbar is positioned adjacent but slightly rearwardly from the rear portion and is coupled thereto through a swivel structure which defines a horizontal roll axis which extends in the longitudinal direction of the vehicle. The crossbar mounts a pair of hitch balls adjacent the opposite ends thereof. The trailer has a tongue structure provided with a pair of sidewardly spaced couplers for releasable engagement with the hitch balls.
