A dynamic adjustment method while driving a vehicle of at least one vehicle operating parameter is for a vehicle having an electronic control unit adapted to set the operating parameter, and a communication interface operatively connected to the electronic control unit. An application program is installed on board a portable processing device including a communication interface communicating with the vehicle communication interface. The application program accesses an electronic map of a path and divides the path in sectors. Operating parameter values are stored via the application program, each value being associated to a corresponding sector. While driving, the sector occupied by the vehicle is identified in real time. Values are transmitted sector by sector, from the portable processing device to the electronic control unit so that the electronic control unit sets, sector by sector, the vehicle operating parameter vehicle to the value associated to the occupied sector.

A system for determining an axle load for an agricultural tractor. The system includes an axle or wheel suspension device arranged on a front axle of the agricultural tractor and has a hydraulic spring strut having a hydraulic cylinder and a hydraulic piston dividing the hydraulic cylinder into an annular space and a piston space. A first pressure sensor detects a first working pressure, which is present in the annular space. A second pressure sensor detects a second working pressure, which is present in the piston space. A control device calculates a front axle load variable which represents an axle load acting on a front axle on the basis of a pressure force difference derived from the first and second working pressures.

The present disclosure relates to a noise reduction system for an automobile suspension for reducing structurally transmitted noise caused by vibrations generated when a damper of the suspension operates and entering the interior of the automobile. The noise reduction system comprises: a vibration detection unit that is mounted on the suspension damper; an anti-phase vibration generator that is mounted on a top mount portion of a vehicle body on which the suspension damper is mounted and generates vibration in an opposite phase to vibration generated when the damper operates to be applied to the top mount portion; and a control unit that receives a measurement value detected by the vibration detection unit, calculates a target anti-phase vibration, and controls the anti-phase vibration generator.

A snow vehicle having a body spring subject to a load compression dictated by a control circuit. The control circuit generates a resultant load compression value by combining a pre-load compression value and a slope offset value. The pre-load compression value may be controlled by a pre-load control mechanism accessible to a user. The slope offset value may be controlled by an inertial management unit responding to data generated by a sensor array. The sensor array may comprise an accelerometer and generate 6-dimensional accelerometer data.
