Abstract: Method and equipment for estimating a braking factor for a braking system for a vehicle. The method includes estimating a braking factor (kbrk) for a braking system for a vehicle, in which the braking factor (kbrk) is by applying the following equation: kbrk = a + b * Vveh + c * pbrk + d * Tbrk + f * pbrk2, in which a, b, c, d and f are model parameters, Vveh is a velocity of the vehicle, pbrk is a braking pressure, and Tbrk is a brake temperature.

Abstract: Method and equipment for estimating a brake temperature, method for estimating a braking factor and computer program product, including a method for estimating a brake temperature of a brake disc of a vehicle, by performing the following: virtually separating the brake disc in a brake disc body and a brake disc contact surface layer; and estimating the temperature of the brake disc contact surface layer in dependence of the temperature of the braking disc body and a heat input in the brake disc contact surface layer due to a braking action, in which the estimated temperature of the brake disc contact surface layer corresponds to the brake temperature.
