Abstract
A control circuit for a controllable electric solenoid valve of a brake system of a motor vehicle is described, in which the actual values of a controlled variable (f(t)), e.g., the vehicle deceleration, a wheel slip, a driving speed, an angle of rotation or the like are returned to a predetermined tolerance band. The actual value of the controlled variable is measured continuously and compared with the predetermined tolerance band, which is stored in an EEPROM, for example. If the actual value of the controlled variable leaves the predetermined tolerance band (), a correction device () intervenes and returns the actual value to the predetermined tolerance band by increasing or decreasing the trigger current for the solenoid valve ().
