The present invention provides a vehicle control apparatus capable of determining an oscillating motion with no or less delay. The vehicle control apparatus includes a vehicle behavior detection sensor configured to detect a behavior acting on a vehicle, a vehicle behavior reference value calculation unit configured to calculate a reference value of the behavior of the vehicle, based on an output value of another sensor than the vehicle behavior detection sensor, and an oscillating detection unit configured to compare the output value of the sensor and the reference value and detect that a trailer towed by a towing vehicle has an oscillating motion, based on a magnitude of an amplitude of the output value relative to an amplitude of the reference value.

Apparatus for braking a coupled tractor-trailer combination (10) in which the tractor (11) includes a drive train (12) one or more operational parameters of which is adjustable and having an engine and at least one ground-engaging member driveably connected thereto via an adjustable ratio transmission; and the trailer includes at least one ground engaging member having at least one trailer brake (28), includes a control circuit (36) for the trailer brake (28) having a control device and one or more fault detectors, the apparatus also including a controller that adjusts one or more parameters of the drive train in response to detection of one or more faults by one or more said fault detectors. A method of operating the apparatus includes carrying out such adjustment when one or more faults is detected.
摘要:
A trailer brake system constructed and arranged to effect the relay of a brake signal from the tractor and an automatically generated brake signal of an electronic control device of the trailer to one or more additional trailers in an expanded vehicle train. In one embodiment, the brake signal is relayed to an additional coupled trailer in the form of an electrical signal via an electrical interface (10). In another embodiment, the brake signal is relayed to an additional trailer by means of a valve device (25). In yet another embodiment, the brake signal is relayed to an additional trailer by means of a combination of electrical signal transmission and valve device.

A brake controller is disclosed for a towed vehicle braking system. The controller is adapted to be mounted in a towing or a towed vehicle having a longitudinal axis for generating a braking control signal to the towed vehicle braking system. The controller comprises an inertial sensor including plural sensor axes adapted to be mounted in an undefined orientation relative to the longitudinal axis for generating sensor data associated with each sensor axis. The controller also comprises a memory device for storing the sensor data associated with each sensor axis and a processor for processing the sensor data with the braking control signal to evaluate orientation of the inertial sensor relative to the longitudinal axis. In particular the brake controller is adapted to control activation of the towed vehicle braking system in a manner that is relatively insensitive to acceleration of the vehicle in a lateral direction and to orientation of the inertial sensor without prescribing a mounting orientation of the brake controller relative to the towing or towed vehicle. A method of operating a brake controller for a towed vehicle braking system is also disclosed.
摘要:
Die Erfindung betrifft ein ein Fahrzeug mit einem hydrostatischen Fahrantrieb (2) und einer Betriebsbremse (3), wobei der Fahrantrieb (2) im Fahrantriebsstrang ein Hydrostatgetriebe (4) aufweist, wobei das Hydrostatgetriebe (4) die Funktion einer Inchbremse bereitstellt, wobei die Inchbremse jedenfalls auch separat von der Betriebsbremse (3) betätigbar ist und wobei ein Anhänger (7) mit einer vom Fahrzeug (1) aus betätigbaren Anhängerbremse (8) an das Fahrzeug (1) ankoppelbar ist. Es wird vorgeschlagen, dass zumindest in einem vorbestimmten Betriebsmodus und bei angekoppeltem Anhänger (7) eine Inchbremsung als solche eine vorbestimmte Anhängerbremsung auslöst.

The present invention also pertains to a coupling head (10, 100, 200) for a trailer, the coupling head comprising a control inlet (16, 106. 206) connected or connectable to be in fluid communication with a control line (44) of the trailer, a supply inlet (14, 104, 204) connected or connectable to a supply inlet line (13) providing a supply pressure, and a supply outlet (34, 138, 224) connected or connectable to be in fluid communication with a supply line (36) of the trailer. The coupling head (10, 100, 200) is arranged such that in an uncoupled state of the coupling head, the control line (44) is exhausted via the control inlet (16, 106. 206) and the supply line (36) is exhausted via a supply exhaust (32, 146, 244), the supply exhaust (32, 146, 244) being sealed against the control inlet (16, 106, 206). The invention also refers to a trailer with such a coupling head (10, 100, 200).
