Abstract

A device for setting movement behavior of gas-exchange valves of an internal combustion engine with a camshaft. The device has a control unit that generates a setting signal for a setting element of a setting device that adjusts the camshaft. A pilot control system is provided which additively corrects the setting signal including determining an estimated value for adjusting the camshaft without taking account of the delay time of the setting device.
