A METHOD FOR CONTROLLING A BRAKING EFFORT OF A TRACTOR UNIT AND A TRACTOR UNIT CONFIGURED TO TOW A TRAILER

The invention relates in one aspect to a method for controlling the braking effort of a tractor unit (10) relative to the braking effort of a trailer (17) being towed by the tractor unit, the method comprising: activating an enhanced braking mode in the tractor unit; receiving a braking command from an operator input device whilst in the enhanced braking mode; increasing a tractor unit speed demand on the tractor unit whilst receiving the braking command; applying the brakes to the trailer and tractor unit, wherein the braking effort applied to the tractor unit is reduced relative to the trailer due to the increased speed demand.In another aspect the invention relates to a tractor unit (10) configured to tow a trailer (17).
