发明名称 METHOD AND DEVICE FOR MONITORING AN ACTUATOR DEVICE
摘要 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.

主权项 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.
