Disclosed is a method for controlling a speed of a vehicle in a downhill road section followed by an uphill road section. The vehicle comprising an electrical machine system for applying braking to the vehicle to maintain a first vehicle speed in the downhill road section and to apply a propelling power in the uphill road section. The method comprising determining whether a temperature of the electrical machine system will exceed a temperature limit in the uphill road section, if maintaining the first vehicle speed in the downhill road section, and if so, reducing the first vehicle speed to a second vehicle speed in the downhill road section such that, in comparison to when the first vehicle speed would have been maintained, the temperature of the electrical machine system is decreased when the vehicle reaches the uphill road section and a travelling time in the downhill road section is increased.
