Operating a motor vehicle with an advanced motor restart out of the engine-off coasting mode

A control device for a motor vehicle, the control device comprising:

• a memory storing instructions;
• and
• a processor configured to access and execute the instructions stored on the memory;
• wherein the instructions, when executed by the processor, cause the processor to:
• coast the vehicle in a first operating state within a predetermined speed range, the first operating state defined by conditions wherein the internal combustion engine is off and separated from the drivetrain by the releasable clutch;
• sense a braking operation initiated by a driver while in the first operating state;
• predict whether a power demand is expected within a predetermined time interval;
• and
• if the power demand is expected, set the crankshaft of the internal combustion engine in rotation, or increase a rotational speed of the crankshaft in preparation for an engine restart.
