Abstract

The present invention relates to a method for controlling a vehicle in association with a descent, the vehicle having a powertrain comprising: a drive unit configured to provide propulsion power; an auxiliary brake device; and a first cooling circuit comprising a first coolant; wherein the drive unit and the auxiliary brake device are arranged to be selectively connected or disconnected with/from the first cooling circuit, wherein the drive unit has a first maximum temperature and the auxiliary brake device has a second maximum temperature higher than the first maximum temperature, the method comprising: controlling the drive unit to reduce the provided propulsion power when the vehicle is approaching an upcoming descent, which fulfils predetermined criteria; disconnecting the drive unit from the first cooling circuit; connecting the auxiliary brake device with the first cooling circuit; and controlling the auxiliary brake device to brake to vehicle down the descent.
