Abstract
A controlled brake booster that may have an external trigger is provided. The brake booster includes a control circuit, an electromagnet positioned within the control circuit that activates the brake booster, a superordinated function unit and at least one signal processing device for determining a parameter that is related to the temperature of the electromagnet from values processed in the control circuit. Nominal value for the electromagnet, in the form of a mathematical model, and actual values pertaining to the electromagnet are processed in the control circuit. A preferred embodiment of the booster utilizes internal magnetic signals without requiring special temperature sensory equipment.
