Patent ID: 8230955

Claim:
A method of controlling an overrun operation in a motor vehicle equipped with an internal combustion engine and an electric machine, wherein an overrun switch-off of the internal combustion engine occurs under predetermined switch-off conditions by interrupting a fuel feed to the internal combustion engine, and wherein upon reaching or falling below a predetermined restoring speed, the fuel feed is resumed, the method comprising the acts of: in an operating condition with the overrun switch-off active, monitoring a transmission line between an output of the internal-combustion engine and an input of a transmission device for whether a torque difference occurs that is greater than or equal to a predetermined limit torque; and when said torque difference occurs, driving the internal combustion engine by the electric machine that is coupled with a crankshaft of the internal combustion engine to adjust a rotational speed of the internal combustion engine to be greater than or equal to the restoring speed.
