1. A method for controlling a speed of a vehicle, comprising:

  • generating an acceleration-demand signal which represents one of a positive setpoint acceleration of the vehicle and a negative setpoint acceleration of the vehicle;

    outputting one of a first control command to an engine of the vehicle and a second control command to a braking system of the vehicle as a function of the acceleration-demand signal;

    outputting a signal for preloading the braking system when the acceleration-demand signal falls below a threshold value which is above a value at which the braking system is activated;

    determining a triggering threshold as a function of a vehicle deceleration; and

    restricting a change rate of the acceleration-demand signal over time by a lower limit.
