METHOD AND EQUIPMENT FOR ESTIMATING A BRAKING FACTOR FOR A BRAKING SYSTEM FOR A VEHICLE

The invention relates to a method for estimating a braking factor (k) for a braking system for a vehicle, wherein the braking factor (k) is by applying the following equation: k brk = a + b * v veh + c * p brk + d * T brk + f * p brk 2 , wherein a, b, c, d and f are model parameters, v is a velocity of the vehicle, p is a braking pressure , and T is a brake temperature.
