Title: Vehicle adjustment device positioning control method and appts. e.g. for throttle valve
Inventor: WELLER SYBILLE DIPL ING
IPC: F02D11/10
Filed: 1994-07-29
Abstract: The control element is driven by a stepping motor with the control system adding correction signals to cater for motor hysteresis, when changing direction, and to compensate for tolerances in the construction of the system. One of the reference points is the momentum change position at which the two return springs apply equal and opposite forces onto the control element eg. the idling position. The control signals have preset offset values added. Tolerance induced errors can be corrected for by measuring the difference between the computed idling point and the actual point. The hysteresis correction is applied for each drive signal dependent on the drive direction.
