用于操控车辆动力传动系的方法
摘要：
用于操控车辆(1)的动力传动系(2)的方法，所述动力传动系具有至少一个驱动单元(4)、尤其是电动马达，动力传动系(2)具有：至少一个第一子动力传动系(2-1)，其配设给第一从动单元(6；10；11)、尤其是第一车轮(10；11)和/或被驱动的第一车桥(6)并且其在驱动单元(4)与第一从动单元(6；10；11)之间传递转矩(M)；第二子动力传动系(2-2)，其配设给第二从动单元(8；12；13)、尤其是第二车轮(12；13)和/或被驱动的第二车桥(8)并且其在驱动单元(4)与第二从动单元(8；12；13)之间传递转矩(M)，在传递正转矩(+M)时动力传动系(2)沿第一方向被加载负载，在传递负转矩(-M)时动力传动系(2)沿与第一方向相反的第二方向被加载负载，还设有至少一个预紧装置(14；16)，该预紧装置在达到预定的正转矩极限值(M1)时或在达到预定的负转矩极限值(M2)时沿正转矩(+M)的第一方向预紧第一子动力传动系(2-1)和沿负转矩(-M)的第二方向预紧第二子动力传动系(2-2)。
摘要（英）：

A method for actuating a vehicle drivetrain (2) of a vehicle (1) having at least one drive unit (4), in particular an electric motor, wherein the drivetrain (2) has at least one first partial drivetrain (2-1) which is assigned to a first output unit (6; 10; 11), in particular to a first wheel (10; 11) and/or to a first driven vehicle axle (6), and which transmits a torque (M) between the drive unit (4) and the first output unit (6; 10; 11), and having at least one second partial drive train (2-2) which is assigned to a second output unit (8; 12; 13), in particular to a second wheel (12; 13) and/or to a second driven vehicle axle (8), and which transmits a torque (M) between the drive unit (4) and the second output unit (8; 12; 13), and wherein when a positive torque (+ M) is transmitted aload is applied to the drivetrain (2) in a first direction, and when a negative torque (- M) is transmitted a load is applied to the drivetrain (2) in a second direction opposed to the first direction, wherein furthermore at least one pre-tensioning device (14; 16) is provided which, when a predetermined positive torque limiting value (Mi) is reached or when a predetermined negative torque limiting value (M2) is reached, pre-tensions the first partial drivetrain (2-1) in the first direction of the positive torque (+ M) and pre-tensions the second partial drivetrain (2-2) in the second direction of the negative torque (-M).
