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. |

1. A method for assessing the status of an electromechanical actuator apparatus, particularly for a valve control, wherein the actuator apparatus is in particular provided for the controlling of control element devices in an internal combustion engine, particularly in a motor vehicle, characterized in that
in a first method step, an actuating power (2) is supplied to the actuator apparatus, that in a second method step, the supply of actuating power (2) is reduced, in particular interrupted, that in a third method step, a control line device (5) is monitored and an actuator assessment parameter determined from the data thereby acquired, and that in a fourth method step, the actuator assessment parameter is assessed using a comparative value based on the actuating power (2) supplied. |
