Abstract: A method for influencing the driving dynamics of a motor vehicle wherein the vehicle speed and the transverse acceleration are feed as input signals to a regulating and control unit in which an actuation signal is produced when a limiting value of a variable which determines the driving condition is exceeded. When a limiting value of the vehicle speed and/or the transverse acceleration is exceeded, throttle-valve actuating signals for limiting the throttle-valve position are provided and when a determined change in the transverse acceleration over time exceeds a limiting value, a clutch actuating signal is produced for opening the clutch.

Abstract: A method for determining the ignition angle for an internal combustion engine with adaptive knocking control, in which the occurrence of knocking is reduced by a controlled adjustment of the ignition angle in the retarded direction. The current values for the adjustment in the retarded direction are stored in a characteristic diagram in an operating parameter-dependent fashion. An average adjustment in the retarded direction is determined from these characteristic diagram values, and both a correction ignition angle and a control range limitation for the knocking control are determined therefrom. The fuel quality and ambient influences are automatically sensed with reference to a learned RON level and are also used to reduce the amount of energy expended to control engine knocking.

Abstract: In a method of controlling a supercharged internal combustion engine of a motor vehicle wherein the engine includes a supercharger operated by the engine by way of a clutch and a return air flow duct including a return air flow control value is provided for returning air from the charger outlet side back to the charger inlet side and wherein the engine includes an engine control unit for controlling operation of the engine on the basis of a plurality of sensor values, the return air flow control valve and the charger clutch are controlled depending on operating parameters of the engine and of the motor vehicle so as to achieve various engine operating conditions and a certain vehicle behavior under certain vehicle operating conditions.
