Simplified Disc Brake Modeling, Identification, and Validation focusing on Temperature Influences

Abstract

In this paper an overall, simplified modeling approach describing the dependency between applied brake pressure and brake torque is presented. Therefore the internal amplification of a disc brake, the so-called brake-factor, is modeled in dependency of the vehicle velocity, the brake pressure and the brake temperature. As the application of this model requires the brake temperature, which is commonly not measured, a new lumped-mass-based brake temperature model, that describes the thermal behavior of a typical disc brake is stated and validated.
