发明名称 Work machine drive train torque vectoring
摘要 A machine may include a powertrain drivingly connected to left and right front and rear wheels through a torque transfer unit to transfer torque to the front wheels as a function of a desired front torque and to the rear wheels as a function of a desired rear torque. At least one sensor of the machine may detect a value of an operating parameter indicative of a weight distribution of the machine across the wheels, and generate a parameter signal corresponding to the operating parameter. A control unit determines the weight distribution across the wheels as a function of the parameter signal, and the desired front and rear torques as a function of the weight distribution. The control unit also considers the weight and position of a load of material borne by an implement of the machine in determining the weight distribution.

主权项 1. A machine, comprising: a powertrain drivingly connected to at least one left front wheel, at least one right front wheel, at least one left rear wheel, and at least one right rear wheel through a torque transfer unit, the torque transfer unit configured to transfer torque to the front wheels as a function of a desired front torque, and to transfer a different torque to the rear wheels as a function of a desired rear torque, wherein the powertrain is drivingly connected to the front wheels through a front differential and to the rear wheels through a rear differential, the front and rear differentials configured to transfer torque to the left wheels as a function of a desired left torque, and to transfer a different torque to the right wheels as a function of a desired Light torque; at least one sensor configured to detect a value of an operating parameter of the machine that is indicative of a distribution of a weight of the machine across the left and right front and rear wheels of the machine, and to generate a parameter signal corresponding to the value of the operating parameter; and a control unit configured to determine the weight distribution of the machine across the left and right front and rear wheels of the machine as a function of the parameter signal and to determine the desired front torque and the desired rear torque as a function of the weight distribution, and wherein the control unit is configured to determine the desired left torque and the desired right torque as a function of the weight distribution.
