    摘要: A method for operating a vehicle drive train comprising a drive unit, a transmission, and an all-wheel splitter having a clutch. The all-wheel splitter is positioned between the transmission and the output and splits a transmission output torque to vary the torque distribution to driven axles of the output. The split of the output torque to the driven axles is performed by a control unit in such a way that the transmission output torque, less a predetermined nominal torque set by the all-wheel drive strategy, is transferred to a first axle while the nominal torque is transferred to a second axle. When defined operating conditions are met, a clutch monitoring function is activated and the nominal torque is replaced by a torque definition of the clutch monitoring function so that the torque which is transferred by clutch to the second driven axle, is increased, then kept constant, and thereafter reduced.

    摘要: Problems of work efficiency reduction by tire slip; durability reduction by tire damage; and large tire-changing costs for users are solved by preventing repeated tire slip occurrence in situations where tire slip likely occurs such as during excavation. A working vehicle of this invention has a work equipment, and an engine power is transmitted as driving force to the tires via a driving force transmission path. Driving force variation means for freely varying the driving force transmitted to the tires is provided in the transmission path of the working vehicle. Tire slip detection means detects tire slip occurrence. When the tire slip detection means detects tire slip, driving force measurement means measures the driving force at the time of tire slip detection. Driving force control means controls the driving force variation means such that the driving force becomes smaller than that at the time of tire slip detection.

    摘要: A clutch control device is provided for a clutch to connect and disconnect the transmission of a rotational drive force from a power source to a drive wheel in a vehicle. A clutch control unit is configured to control a control amount for said clutch. A drive wheel rotation start detector is configured to detect a start of rotation of said drive wheel. A control correction amount calculator is configured to calculate a control correction amount of said clutch based on a difference between the clutch control amount detected at the start of rotation of said drive wheel and a predetermined reference value. The clutch control unit is further configured to apply said control correction amount to the control amount for said clutch to control said clutch.
