Abstract: A method for controlling a motor vehicle, comprising: retrieving road gradient data relating to an expected travelling route of the motor vehicle; based on at least the retrieved road gradient data and on a motor vehicle mass, simulating a required value of a braking power related variable, which required value is needed to prevent a vehicle speed from increasing above a preset desired vehicle speed in an upcoming downhill slope; determining an available value of the braking power related variable of at least one auxiliary brake of the motor vehicle; and based on the determined available value and the simulated required value of the braking power related variable, controlling the vehicle speed and/or at least one brake actuator of the motor vehicle such that the vehicle speed does not increase above the preset desired vehicle speed in the upcoming downhill slope.
