More Information
Summary:A braking system for a heavy duty vehicle includes a first brake controller arranged to control braking on a first wheel and a second brake controller arranged to control braking on a second wheel, based on a respective configured wheel slip limit and on a respective brake torque request, wherein the first and the second brake controllers are interconnected via a back-up connection arranged to allow one of the first and the second brake controller to assume braking control of the wheel of the other of the first and the second brake controller in case of brake controller failure, the braking system comprising a control unit arranged to, in response to brake controller failure, reduce the configured wheel slip limit associated with the failed brake controller to a reduced wheel slip limit.
