Auxiliary device control process for motor vehicle involves finding actual overall loss torque on drive train, finding switch-off dead time, and controlling on this basis

摘要

The control process is for the auxiliary devices of a motor vehicle driven by an engine (1) with automatic transmission (4). It involves finding the actual overall loss torque on the drive train, finding the switch-off dead time, estimating the overall loss torque after the switch-off dead time, and switching off the auxiliary units (NA1, NA2, NAn) when a preset maximum torque threshold is exceeded by the estimated overall loss torque.
