Patent ID: 8639417

Claim:
A method for regulating a position and speed of a retractable display apparatus which is arranged inside a motor vehicle and can be moved along a predefined course using an electric motor, the method comprising: performing a regulating operation to control the electric motor using pulse width modulation as a manipulated variable; setting position and speed as controlled variables; performing the regulating operation continuously in such a manner that targeted fluctuation of the controlled variables of position and speed around their desired values is respectively achieved within a predefinable tolerance range by setting the manipulated variable; using an array to describe a desired position of the retractable display apparatus arranged inside the motor vehicle at a particular time; comparing, in two first tables, the desired controlled variable values with actual controlled variable values for determining a degree of deviation of each of the controlled variables; and during the regulating operation, using a second table for determining correction values for the pulse width modulation as the manipulated variable.
