Abstract: A vehicle transmission includes a first transmission mechanism arranged to transmit mechanical driving power from an output shaft of the prime mover to a first input shaft and to put any one of a first set of gears in an engaged state to drivingly connect the first input shaft to the driving wheels; and a second transmission mechanism arranged to transmit mechanical driving power from the output shaft of the prime mover to a second input shaft and to put any one of a second set of gears in an engaged state to drivingly connect the second input shaft to the driving wheels. Controllable first and second clutch units are arranged to bring the output shaft of the prime mover and the first and the input shaft, respectively, into engagement with each other. A lubrication pump is drivingly connected to the first input shaft to lubricate the transmission and an electronic control unit is arranged to determine a lubricated state of the transmission and the operational state of the lubrication pump. When the first clutch unit is engaged to connect the output shaft of the prime mover to the first input shaft, the lubrication pump is driven by the first input shaft. When the second clutch unit is engaged to connect the output shaft of the prime mover to the second input shaft, the lubrication pump is arranged to be driven by the first input shaft by at least partly engaging the first clutch unit.

Abstract: A control device of a wheel loader obtains a first ratio between a value corresponding to a target traveling distance for the wheel loader, when it travels to a discharge position where an excavated substance is discharged after an excavation with a bucket, and a value corresponding to a target elevation amount for an elevation of a boom after a motion is started. The control device also obtains a second ratio between a value corresponding to an actual traveling distance after the wheel loader starts its motion to the position where the excavated substance is discharged after the excavation with the bucket, and a value corresponding to an actual elevation amount of the boom after the motion is started. The control device then controls a transmission toque transmitted to a drive wheel from an engine in order that a difference between the first ratio and the second ratio becomes zero.

Abstract: An electronic traction optimization system includes a control unit adapted to produce a corner speed estimate signal for each wheel of a machine, produce an ideal target speed signal for each wheel having a value at least partially responsive to the corner speed estimate signals, produces a practical target speed signal for each wheel, generates an actual target speed signal having a value responsive to a comparison of the ideal target speed signal and the practical target speed signal for each wheel. The control unit compares each actual target speed signal to an associated wheel speed signal to obtain a wheel speed error signal for each wheel and converts each wheel speed error signal to a clutch control signal, wherein each differential clutch actuator is responsive to an associated clutch control signal.

Abstract: A method for control of an automatically controlled clutch when setting a vehicle (100) in motion on a running surface: the vehicle includes a combustion engine for generating driving force intended for transmission to at least one powered wheel, and a throttle control for demanding driving force from the engine. The magnitude of the driving force demanded from the engine is controlled by a driver of the vehicle by means of the throttle control. The method comprises the step, when a first criterion for a representation of the grip of the powered wheels on the running surface is fulfilled, of opening the automatically controlled clutch if the driver uses the throttle control to reduce the demand for driving force from the engine.
