A method for controlling a drivetrain of a motor vehicle is disclosed. Either a start mode for starting the reciprocating engine is activated via the driving vehicle wheel, or a coasting mode is activated for driving the reciprocating engine via the driving vehicle wheel. At least one volume-reducing stroke is executed that follows an intake stroke for at least one cylinder of the reciprocating engine with at least intermittently open cylinder. Alternately at least one volume-enlarging stroke is executed for at least one cylinder of the reciprocating engine, which is followed by a compression stroke of this cylinder, and at least one volume-reducing stroke of this cylinder, which follows an expansion stroke that follows the compression stroke, with a cylinder that is closed, if possible, in this operating mode.
