Abstract: The present invention relates to a vehicle braking arrangement for a vehicle with wheels contacting the ground during normal running. The vehicle braking arrangement includes an emergency brake control unit, a first emergency braking system including non-reversible braking means arranged to operate independently of the vehicle wheels, at least one acceleration detector, and a wheel brake anti-locking system. The emergency brake control unit is arranged to input acceleration data (a) when the wheel brake anti-locking system is active, and to calculate the coefficient of friction (μ) between the wheels and the ground. The emergency brake control unit is arranged to determine if the first emergency braking system should be activated in dependence of a first plurality of parameters, where one of these parameters is the coefficient of friction (μ).
