Abstract
A control system is provided for an articulated vehicle including a towing vehicle, a trailer and an autonomous emergency braking system, wherein the control system includes: a brake control arrangement adapted to apply a friction-estimating braking; a brake force capacity estimation arrangement adapted to estimate the brake force capacity of the vehicle as a function of longitudinal wheel slip based on the applied friction-estimating braking; an axle load estimation arrangement adapted to estimate the normal force on each wheel axle of the vehicle; a friction estimation arrangement adapted to estimate a friction coefficient based on the estimated brake force capacity and at least one of the estimated normal forces; and a brake strategy adaptation arrangement configured to adapt the brake strategy of the autonomous emergency braking system by adjusting the brake force for at least one wheel axle of the Vehicle based on the estimated friction coefficient and the at least one wheel axle's estimated normal force.
