Method for controlling direct current electric motor for exhaust gas recirculation valve of internal combustion engine for car, involves sending control value to motor, where value is lowest value between rough and secure control values

摘要

The method involves controlling actuation a direct current (DC) electric motor (2) by using a rough control value (Cb) generated by a control device (5). A control value (Cf) is sent to the motor, where the sent control value is a lowest value between the rough control value and a secure control value, which is associated with and determined from temperature (T) of winding of the motor, voltage (U) applied to the motor, current (I) passing through the motor and a rate of travel (W) of a movable component of a valve (1) actuated by the motor.
