Method for operating a motor vehicle

A vehicle comprising:

• an engine selectively coupled to a powertrain;
• and
• a controller configured to disengage the engine from the powertrain or stop the engine in response to a freewheeling distance exceeding a threshold, the freewheeling distance calculated by the controller using signals indicative of at least two of vehicle speed, vehicle acceleration, vehicle braking pressure, and distance to a forward vehicle.

A method for controlling a vehicle having an engine selectively coupled to a driveline by an electrically controllable clutch, comprising:

• stopping the engine in response to a freewheeling distance calculated by a vehicle controller exceeding an associated threshold, the freewheeling distance calculated in response to vehicle signals or data corresponding to at least three of vehicle speed, vehicle acceleration, braking pressure, distance to a forward vehicle, tire pressure, and vehicle weight.
