Original Abstract Submitted
A computer system has processing circuitry configured to receive a braking request for braking a vehicle including an electrically powered tractor, and a trailer coupled to the tractor by an articulated coupling; provide a first braking command encoding instructions to control braking on at least a front axle of the tractor, and on a rear drive axle of the tractor to provide a combined braking force fulfilling the braking request; receive a first set of vehicle parameters; determine, based on the first set of vehicle parameters, that an understeer tendency of the vehicle during braking is higher than a predefined first understeer tendency threshold; and provide a second braking command encoding instructions to increase a braking force on the rear drive axle of the tractor using regeneration, and decrease a braking force on the front axle of the tractor, so that the combined braking force fulfills the braking request.
