    摘要： The invention relates to a method for measuring and estimating a brake factor (Bf) in a vehicle brake system, said vehicle (1 ) comprising a towing vehicle (2) and a trailer (3) having a plurality of wheel axles (4, 5, 6, 7), wherein said method comprises: initiating a controlled braking manoeuvre involving at least a first wheel axle (4) and a second wheel axle (5); and obtaining values representing said brake factor (Bn; BR) for said wheel first wheel axle (4) and said second wheel axle (5) by means of a control unit (13) which is provided with a brake adaptation function to obtain a brake balance between said towing vehicle (2) and said trailer (3). According to the invention, said method furthermore comprises the following steps: braking (17), in a forced manner, said first wheel axle (4) when retardation of said vehicle (1) is requested; estimating (18) the brake factor (Bf1) for said first wheel axle (4) by determining the brake pressure (Pcyn) and braking torque (Tbrake-i) for said first wheel axle (4); providing a transition phase (19) after which said second wheel axle (5) is braked, in a forced manner, and estimating (20) the brake factor (Bf2) for said second wheel axle (5) by determining the brake pressure (Pcyιi) and braking torque (Tbrake2) for said second wheel axle (5). The invention also relates to an arrangement for measuring and estimating the brake factor in a vehicle brake system.

    摘要： The invention relates to a method for assisting a driver of a vehicle during operation in order to avoid an undesired situation based on a current driving scenario characterized by the steps of - predicting if a first guiding force to a vehicle steering device is desired in order to avoid said undesired situation, and if the first guiding force is desired: - predicting a total guiding force comprising the first guiding force, which would be applied to the steering device for avoiding the undesired situation,. - comparing the predicted total guiding force with a limit value, and if the predicted total guiding force exceeds the limit value: - in advance deciding whether to apply said predicted total guiding force to the steering device for avoiding the undesired situation or not.
