<p>When performing an automated start, as part of a stop/start function, whilst on an uphill slope an engine of a vehicle can stall due to the brake torque from the wheels. This invention allows the engine to modify the torque it produces to compensate, and allows for wider use of the stop and start function. The disclosed method comprises the vehicle being provided with an internal combustion engine (110, fig.1), a transmission (510, fig.1), a brake system (520, fig.1) and a controller (450, fig.1) for automatically stopping and starting the internal combustion engine Wherein the method performs the following steps: determining a transmission ratio of the transmission S210, determining a vehicle inclination along a longitudinal plane of the vehicle S220, calculating a brake torque S230 as a function of the transmission ratio and the vehicle inclination, and adjusting a torque to be delivered by the engine S240 to compensate for the said brake torque and to perform an automatic engine start.</p> |
