Abstract:
A device for controlling a starting process of a motor vehicle, comprising:an engine having a power regulating element and a crankshaft connectable to a gear input shaft of a transmission via a clutch, the starting process being controllable by activation of the clutch;said power regulating element having an actuator operatively connectable to the engine for regulating a rotational speed of the crankshaft;a control device operatively connected for receiving signals representing an activation position of an accelerator pedal of the motor vehicle and the speed of the crankshaft; andsaid control device operatively connected to said power regulating element for activating said actuator when the speed of said crankshaft reaches a predetermined speed limit value to limit the speed of said crankshaft to said predetermined speed limit value during the starting process, wherein said control device is operatively connected for monitoring parameters of said motor vehicle over time that characterize a predominant driving mode of the motor vehicle, said control device determining said predetermined speed limit value in response to said parameters, and said predetermined speed limit value being in a range between an idle speed of said engine and a speed at which said engine delivers its maximum moment, and wherein said predetermined speed limit value is in a range of the crankshaft speed in which the engine delivers its maximum moment.
