<p>A method is provided for controlling aerodynamic devices, for example an aero shutter or a downforce wing, of an automotive system 100 in a vehicle during sailing driving where an engine 110 of system 100 is stopped allowing the vehicle to coast. During sailing driving, the aerodynamic devices are closed or adjusted, reducing aerodynamic drag, and basic control of the aerodynamic devices is re-established when a time period, which may depend on vehicle speed, expires, sailing driving ceases, for example due to operation of a clutch pedal or an accelerator pedal, or a coolant temperature reaches a predetermined threshold. Advantageously, aerodynamic devices may be closed or adjusted when the vehicle speed exceeds a threshold, for example 4 km/h, and the engine speed is lower than a threshold, for example 100 rpm. Closing or adjusting aerodynamic devices may allow the vehicle to coast for a longer distance, improving fuel economy.</p> |
