Method for assessing the status of an electromechanical actuator device. The actuator device is provided, in particular, for actuating control element apparatuses in an internal combustion engine for a motor vehicle. This actuator device has an activation apparatus and a stator apparatus as well as at least one electrical coil apparatus 1. The actuator device can be changed over from a first operating state into a second operating state. During the changeover from this first operating state into this second operating state, activation power 2 is fed to the coil apparatus 1 by means of a control line apparatus. In a first method step, the activation power is fed to the actuator device. In a second method step, the feeding of the activation power is reduced, in particular interrupted. In a third method step, the control line apparatus is monitored and an actuator assessment characteristic variable is determined from the data acquired in the process. In a fourth method step, the actuator assessment characteristic variable is assessed by means of a comparison variable which is based on the fed-in activation power. |
