Abstract
A cruise control road speed control device optimizes the transient behavior during activation of speed control phases. The cruise control device has an additional device located outside the speed controller in the form of a load adaptation element. The load adaptation element sets the speed control output signal, upon activation of a speed control phase via an engine-load-adjusting additional signal, to a value that is required for a constant transition of the driving-force-determining control signal and in the subsequent transient phase of speed control with linkage to the output signal of the speed controller, for a return of this additional term to a value of zero, without the behavior of the speed controller being influenced thereby. This permits a very smooth transition from a previous driving phase into a cruise-control-determined speed control phase.
