A method is disclosed for controlling a vehicle having a drive train that comprises a variable displacement engine having a crankshaft connected to drive wheels of the vehicle by way of a transmission and an auxiliary machine connected directly to the engine crankshaft and to an energy storage device. The engine mode is switched from a cylinder disablement (VDE) mode to a normal mode when the torque demand and engine speed lie outside an outer range defined by a first threshold (T out ) and is switched from the normal mode to the VDE mode when the torque demand and engine speed lie within an inner range, lying within the outer range and defined by a second threshold (T in ), When operating within a torque demand and engine speed band between the two thresholds, the auxiliary machine draws energy from the energy storage device and supplements the output torque from the engine if operating in VDE mode and derives torque from the engine crankshaft to recharge the energy storage device if the engine is operating in the normal mode.
