Abstract:
A method and an arrangement for controlling a drive unit of a vehicle are suggested. In this method, the control functions for the power of the drive unit and the monitoring of these control functions are carried out by a single microcomputer. A monitoring module, which is separate from the microcomputer, is provided for checking the monitoring functions. The monitoring module transmits test signals to the microcomputer at a given time. The microcomputer then computes the monitoring function on the basis of test data. The result of the computation is transmitted to the monitoring module which checks the operability of the monitoring function in the microcomputer by making a comparison to stored values.
Abstract:
The invention is directed to a method and an arrangement for controlling an operating variable of a motor vehicle. A friction-burdened actuator assembly, which influences the operating variable, is actuated via a drive signal. This drive signal is formed on the basis of a desired value of the operating variable. The drive signal is additionally changed in response to a desired change of the operating variable to transfer the actuator assembly out of a steady state condition preferably so as to effect an actual change of the operating variable. In this way, the static friction of the actuator assembly, which is in opposition to the change of the operating variable, is overcome. Furthermore, the drive signal can be additionally changed in the sense of a reduction of the change of the operating variable when the operating variable approaches the desired value thereof.
