Abstract

A brake system for a heavy vehicle includes a control network, a brake component, a central control unit, and a distributed electronic control unit. The central control unit generates central control signals adapted to control the brake component, which control signals are transmitted to the brake component over the control network. The distributed electronic control unit receives the central control signals, controls the brake component in accordance with the central control signals if the central control signals are received during expected time periods, and controls the brake component in accordance with an alternative control scheme if the central control signals are not received during the expected time periods.
