摘要： In a motor vehicle control unit having a digital control circuit for controlling the electric current, in a way which is robust with respect to the voltage ripple of a vehicle on-board power system, of a control magnet valve for a motor vehicle hydraulic device with simultaneously improved dynamic behavior in response to jumps in a setpoint value current as a reference variable of the control circuit, at least one adaptive correction filter whose filter time can be adjusted dynamically on the basis of the change in level of the setpoint value current is provided in the feedback branch of the digital control circuit.

摘要： A control unit has a closed-loop controller which is connected to a regulating electrovalve by way of a feedback branch, forming a closed-loop control circuit, in order to regulate the electrical coil current of the regulating electrovalve. The armature of the electrovalve is used to adjust a desired volume flow in a motor vehicle hydraulic device. The armature of the regulating electrovalve is continuously subjected to an armature oscillation in order to reduce the static friction and/or magnetic hysteresis. Inside the closed-loop controller of the closed-loop control circuit itself, the nominal current, which is supplied to the closed-loop controller on the input side as a command variable, is subjected to a dither signal generated inside the closed-loop controller for producing the armature oscillation, essentially synchronously to the clock cycle of the closed-loop controller.

摘要： A motor vehicle control device with a digital control loop has an actuator of an electrical actuator device in order to regulate the pressure of the volumetric flow of a motor vehicle hydraulic apparatus. A current limiting unit is provided in the forward path of the digital control loop between the digital controller of the latter and the actuator of the electrical actuator device. The current limiting unit, in order to protect the components of the electrical actuator device, limits the manipulated variable signal from the digital control loop if a predefined permissible current threshold value is exceeded in the electrical actuator device. The digital controller has an additional limiting unit which essentially limits the I component of its manipulated variable signal from the time at which the current limiting unit is activated.
