ACTUATION SYSTEM FOR A DRIVE UNIT OF A MOTOR VEHICLE

摘要

The invention relates to an actuation system for a drive unit of a motor vehicle, having a control unit (100; 400; 500), which is associated with the drive unit and has a function level (3), a function monitoring level (4) and a power output stage (9; 9') for actuating the drive unit or actuators or sensors (2) which are associated with the drive unit. The object of the invention is to provide an actuation system with a high degree of availability together with good error detection and data security. According to the invention, this object is achieved in that the power output stage (9; 9') of the control unit (100; 400; 500) can be operated in accordance with an emergency running torque (Mnot) when an emergency running device (31, 29) detects an error in the data transmission of a desired torque (Msoll_BKM).
