Abstract

On a utility vehicle which includes a towing vehicle, e.g. a truck or tractor unit arranged to haul, for example, a trailer or semitrailer, and which incorporates a brake system, an expected vehicle retardation ( Rbf ), an actual vehicle retardation ( Rbv ) and a vehicle wheel brake efficiency ( nb ) are determined for the towing vehicle's wheel brakes on the basis of the expected towing vehicle retardation ( Rbf ) and the actual towing vehicle retardation ( Rbv ). According to one embodiment, when the towing vehicle is travelling with a trailer, a trailer brake pressure ( Ps ) on the trailer brakes is set on the basis of a trailer wheel brake efficiency ( ns</i>) which is determined on the basis of an excepted combination retardation ( Rkf ) and an actual combination retardation ( Rkv ). According to another embodiment the vehicle incorporates an information means (8) which is arranged to be activated in order to warm the vehicle driver if the vehicle wheel brake efficiency ( nb ) is below a predetermined value.
