  • Patent number: 10661800
    Abstract: A drivetrain for an agricultural vehicle and method for controlling the same. The drivetrain includes first and second driven axles with a variable pivot angle hydraulic motor connectable to drive the first axle through engagement of a first clutch mechanism. A further motor is connected to drive the second axle. In operation, the pivot angle of the variable pivot angle hydraulic motor is reduced with variation in a vehicle parameter value, such as transmission ratio or ground speed, to a point at which the pivot angle reaches zero at a first parameter value. With the pivot angle at zero and parameter value continuing to vary due to the drive of the further motor, the first clutch mechanism is disengaged at a second parameter value, with the first and second parameter values separated by an interval determined at least partly by an operating characteristic of the first clutch mechanism.

A pump output determining section determines a value, where the reduction amount is subtracted from the output of the hydraulic pump which is determined according to the state with the multiple operations, in a first control mode as the output of the hydraulic pump during the multiple operations. The pump output determining section increases the output of the hydraulic pump during the multiple operations in a second control mode more than in the first control mode.

  • Patent number: 9283962
    Abstract: An indirect longitudinal acceleration calculation section indirectly calculates longitudinal acceleration by calculating the longitudinal acceleration, which is an acceleration in a longitudinal direction of the vehicle, from change in the speed of the vehicle detected by a vehicle speed detection section. When an uphill travel detection section detects an uphill traveling state in which the vehicle is traveling on an uphill and a drive state determination section detects a no-driving-force state in which a vehicle driving force is not generated, a vehicle drawn down state detection section detects that the longitudinal acceleration indirectly calculated by the indirect longitudinal acceleration calculation section is oriented in an accelerating direction, and determines that the vehicle is in a drawn down state.

  • Patent number: 8862359
    Abstract: A hydrostatic drive system includes an anti-slip control unit having a hydraulic pump which supplies a plurality of hydraulic motors of a plurality of axles with pressure medium. Based on a detected slip, a control device switches over between a two-wheel and a multiple-wheel drive and controls the driving torque. Optimal distribution of driving torque and traction between the axles or wheels of the drive system is set in the drive system. A method for anti-slip control of a hydrostatic drive system includes reacting to a slip situation by activating a hydraulic motor for axles or wheels which until then were not driven, or driven only with low driving torque or by increasing the driving torque of wheels which until then did not slip. The capacity of the hydraulic motor of the axles or wheels is raised to enable the activation/increase.
