Method for compensating the temperature dependence of an inductive resistance of a valve coil

A method of compensating for a temperature dependence of a coil resistance of at least one second solenoid valve in a hydraulic unit of a vehicle brake system, the method comprising the steps of:

• determining a first temperature of a coil of at least one first solenoid valve of the hydraulic unit;
• determining a second temperature of the hydraulic unit as a function of the first temperature and a first temperature model of the coil of the at least one first solenoid valve, the first temperature model being a function of heat capacity, heat input and heat dissipation of at least one of:
• the coil of the at least one first solenoid valve and the hydraulic unit;
• and
• determining a third temperature of a coil of the at least one second solenoid valve as a function of the second temperature and a second temperature model of the coil of the at least one second solenoid valve, the second temperature model being a function of heat capacity, heat input, and heat dissipation of at least one of:
• the coil of the at least one second solenoid valve and the hydraulic unit, the temperature dependence of the coil resistance of the at least one second solenoid valve being compensated for as a function of the third temperature.
