1. A cruise control road speed control device for a motor vehicle, comprising:

  • a speed controller having a speed controller output signal (R);

    a load adaptation element located outside of, and coupled to, said speed controller, said load adaptation element influencing a cruise control output signal (T) in an initial time period of a speed control phase;

    wherein at an activation time (t0) of the speed control phase, said load adaptation element generates an initial engine load adaptation signal (L0) such that said cruise control output signal (T) based on the initial load adaptation signal (L0), takes over a driving force control signal (G) from a current position of an associated driving-force-determining positioning element at this point in time; and

    wherein said initial engine load adaptation signal (L0) up to an end of the initial period of time of the speed control phase, drops to zero based on a linkage to the speed controller output signal (R).
