Abstract
A cruise control arrangement is provided with a cruise control speed function and where the cruise control arrangement is provided with a set cruise speed value and a set brake cruise speed value, and where the cruise control brake function is active when the vehicle travels downhill, where the cruise control arrangement is adapted to activate at least one auxiliary brake when the vehicle speed reaches the set brake cruise speed, to apply a service brake of the vehicle in order to reduce the speed of the vehicle to a predefined first speed if the vehicle speed exceeds the set brake cruise speed when the least one auxiliary brake is delivering full brake power, where the predefined first speed is lower than the set brake cruise speed. Undesired acceleration during downhill travel can be avoided when the brake power of the auxiliary brake is not sufficient. Further, a required downshift can be delayed, which will improve the fuel consumption of the vehicle.
