Method for changing position of lighting device for motor vehicles, involves forming feedback signal depending on control signal, and calculating signal difference from difference between nominal value and actual value

摘要

The method involves forming a feedback signal (R) depending on a control signal (Q), where a linked signal is supplied to a three-step controller (21). The control signal is determined to control an actuator (9) depending on location of a portion of a nominal value (X) and a portion of an actual value (Y). A signal difference is calculated from a difference between a nominal value and an actual value. A feedback signal is subtracted from the difference signal to get an input signal. An independent claim is also included for a lighting device for motor vehicles.
