Electromechanical components i.e. actuators, temperature controlling method for vehicle, involves detecting temperature of electromechanical components based on duty cycle of electrical signal

The method involves detecting temperature of electromechanical components (103) based on a duty cycle of an electrical signal (107), where the duty cycle provides a relationship between the pulse duration and period duration. The duty cycle is changed by power regulation or voltage regulation for co...

Summary:The method involves detecting temperature of electromechanical components (103) based on a duty cycle of an electrical signal (107), where the duty cycle provides a relationship between the pulse duration and period duration. The duty cycle is changed by power regulation or voltage regulation for compensating temperature-caused changes of conversion degree. The electrical signal is produced by a controller (101). The temperature of the electromechanical components is determined based on a look-up table, in which the duty cycle is assigned to the temperature of the component. An independent claim is also included for a controller for controlling electromechanical components. Die Erfindung betrifft ein Verfahren zum Erfassen einer Temperatur einer elektromechanischen Komponente (103), welche die elektrische Energie oder Leistung eines elektrischen Signals (107) in eine mechanische Bewegung umwandelt, wobei die Temperatur der elektromechanischen Komponente auf der Basis eines Tastverhältnisses des elektrischen Signals (107) erfasst wird.
