The torque output of an engine in a vehicle, is limited, based on the terrain over which said vehicle is travelling. An overall torque ratio between the engine and driveline may be used to calculate the engine torque limit request from the driveline torque limit, the driveline torque limit being selected based on the terrain. Other factor used in the calculation of the torque limit include: the transfer box ratio, the transmission ratio, the engine speed, the transmission input shaft speed, a torque converter slip ratio, the hydrodynamic torque ratio and/or the lockup clutch torque. Torque is limited to protect driveline components over different terrains.
