    • The invention is directed to a method and an arrangement for controlling a drive unit (1) of a motor vehicle. The method and arrangement reduce the lost motion of an operator-controlled element (5), which is actuable by the driver, up to an increase of the road speed of the vehicle beyond the road speed pregiven by the road speed controller (10). The degree of actuation (F) of the operator-controlled element (5) is detected and a desired value (S) for the torque of the drive unit (1) is formed from this degree of actuation (F). The desired value (S) for the torque is compared to a pregiven value (V) for the torque requested just then by the road speed controller (10). The torque of the drive unit (1) can only then approach the desired value (S) via control of the drive unit (1) when the desired value (S) exceeds the input value (V). The course of the desired value (S) for the torque is selected as a function of the degree of actuation (F) of the operator-controlled element (5) so that a pregiven value (VW) for the degree of actuation (F) of the operator-controlled element (5) is not exceeded at an intersect point (SP′) of the course of the desired value (S) for the torque and the input value (V) just then requested by the road speed controller (10).
    • 本发明涉及一种用于控制机动车辆的驱动单元(1)的方法和装置。 所述方法和装置减少驾驶员可以驱动的操作者控制的元件(5)的运动,直到道路速度控制器(10)所预期的道路速度超过车辆的道路速度。 检测到操作者控制元件(5)的致动度(F),并且通过该致动程度(F)形成驱动单元(1)的扭矩的期望值(S)。 将扭矩的期望值(S)与刚刚由道路速度控制器(10)请求的转矩进行比较(V)。 当期望值(S)超过输入值(V)时,驱动单元(1)的扭矩只能经由驱动单元(1)的控制而接近期望值(S)。 作为扭矩的期望值(S)的过程被选择为操作者控制元件(5)的致动程度(F)的函数,使得用于驱动程度(F)的预定值(VW) 在对于扭矩的期望值(S)的过程的交点(SP')和刚刚由道路速度控制器(10)请求的输入值(V)不超过操作者控制元件(5) )。
