Abstract
The invention relates to a control unit for a pressure regulating valve in a motor vehicle, preferably for a pressure regulating valve that adjusts the oil pressure, wherein a signal that corresponds to the pressure that is to be set can be transmitted to the control unit, the control unit is signal-connected on the output side to a pressure regulating valve for the fluid that is to be pressure adjusted, wherein the electrical current supply to the pressure regulating valve is provided by way of a PWM signal that is generated by means of the control unit and the control unit is embodied for the purpose of over-exciting the solenoid of the pressure regulating valve with a higher electrical current prior to influencing the pressure regulating valve with the electrical current that is associated with the pressure that is to be set for a period of time.
