    摘要: Presented is an electronically commutated electric motor having a power output stage connected to a stator of the electric motor, and a processing unit connected to the power output stage. The processing unit drives the power output stage to produce at least one stator current. The electric motor has a current sensor which is designed to record the stator current produced by the power output stage and to generate a current signal representing the stator current. The processing unit is designed to use the current sensor to record at least one current value of the current at a recording time within an interval of time and to determine a current profile of the current in the interval of time at least on the basis of the current value and to drive the power output stage to energize the stator on the basis of the current profile determined.

    摘要: A method and device for adapting a stop of an electrically triggered actuator are provided, which may be implemented in a precise and simple manner and allow for a continuous adaptation. For this purpose, a check is performed to determine whether a setpoint value for a position of the actuator to be set corresponds to a stop of the actuator. In this case, a characteristic variable of the trigger signal for triggering the actuator formed for implementing the setpoint value is compared with a predefined value. Depending on the result of the comparison, a position of the stop of the actuator is adapted.

    摘要: In a method and a device for controlling an actuator, the first setpoint value for the position of the actuator is predefined. A change in the setpoint value for the control of the actuator to the first setpoint value is limited to a first setpoint value change limitation. For the reaching of the first setpoint value, a second setpoint value is predefined. A change in the setpoint value for the position of the actuator to the second setpoint value is limited to a second setpoint value change limitation. If the actual value of the change of the setpoint value to the first setpoint value using the first setpoint value change limitation would be greater than the change of the setpoint value to the second setpoint value using the second setpoint value change limitation, the first setpoint value is predefined for the setpoint value and the change in the setpoint value for the control of the actuator to the first setpoint value is limited according to the first setpoint value change limitation.
