Abstract: A method for controlling the speed of a vehicle, the method making it possible to maintain a predefined setpoint speed even on downhill grades. In the event that the actual speed of the vehicle exceeds the predefined setpoint speed by more than a first predefined speed difference, a service brake of the vehicle will be activated.

Abstract: In a method for controlling a speed of a vehicle, when an actual speed of the vehicle exceeds a predefined setpoint speed by more than a first predefined speed difference, a service brake of the vehicle is activated. In the method, the first predefined speed difference has a value greater than zero. Also, when the actual speed exceeds the setpoint speed by a second predefined speed difference, which is smaller than the first predefined speed difference, an idle speed control can be activated and a torque request of activated ancillary components can be reduced. Further, when the actual speed exceeds the setpoint speed by a sixth predefined speed difference, which is smaller than the first predefined speed difference, an ancillary component can be activated.

Abstract: A method for operating a vehicle, in which the method allows feedback about imminent risks. In this context, the vehicle moves on a predefined route at a current traveling velocity. A value characteristic of the vehicle movement along the predefined route is precalculated as a function of the current traveling velocity and the predefined route. A vehicle function is activated as a function of this value.

Abstract: A method and an arrangement for the speed control of a vehicle as well an operator-controlled element are disclosed which make possible an improved acceleration and/or deceleration input by the driver of the motor vehicle. The speed control takes place in dependence upon a value for an acceleration and/or deceleration of the motor vehicle with this value being pregiven with the aid of an operator-controlled element. The function of the operator-controlled element is different from the function of an accelerator pedal and a brake pedal. With the actuation of the operator-controlled element, one of several different values for the acceleration and/or deceleration is selected and pregiven.
