Problems solved by technology

This means, however, that perhaps more energy is consumed than is required for the desired increase in movement speed
[0005] Another problem is the tolerance of the wires (especially the cable harness in the vehicle in which the actuator is built) and the resistance of the solenoid coil, which in addition may vary from actuator to actuator; especially also due to aging phenomena, especially Due to changes in the cable harness in the vehicle during operation, additional current values ​​can result at which the actuating element begins to move

Embodiment Construction

[0015] in figure 1 An inductive actuator A with an operating element and an electromagnetic coil is shown, and the actuator can be applied with a supply voltage to the power supply terminal 1. To this end, the power supply terminal 1 is connected to the power supply output 2 of the circuit arrangement IC, which can be realized in particular as an integrated circuit. On the one hand, the circuit device IC is used to generate and / or process additional signals, especially control signals (not shown) for the actuator A, but the circuit device should also process the supply voltage from the voltage supply unit SV if necessary and Connect it to the actuator A, where the circuit device IC is connected to the voltage supply unit.

[0016] The control input terminal 3 of the circuit device IC is connected with the control output terminal 4 of the microprocessor μC, and obtains the signal generated by the program for controlling the actuator A at a defined time. To this end, the program ...

Abstract

The invention relates to a method for controlling an inductive actuator having an actuating element and an actuator coil, in which, in order to move the actuating element against a spring force, first a voltage of a first value is applied to the actuator coil, and during operation A voltage having a second, larger value is applied when the operating member starts to move, wherein the second voltage value is selected according to how fast the operating member should be moved.

Description

Technical field [0001] The present invention relates to a method for controlling an inductance of an actuator having an operating element and an electromagnetic coil. In order to move the operating element against the spring force, a voltage having a first value is first applied to the electromagnetic coil, and the operating element starts When moving, a voltage with a larger second value is applied. Background technique [0002] The inductive actuators used in motor vehicles, such as fuel nozzles, valves or pumps, are energized by means of the existing battery voltage in the motor vehicle or a voltage derived therefrom that can be higher or lower than the battery voltage. The resistance of the wire, the winding resistance of the solenoid coil of the actuator and its inductance realize an exponential increase in current. Therefore, a magnetic field is formed by which a force acting in the opposite direction to the spring force, such as the spring force of the closing spring, is ...
