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.
Claims31
A brake system for a heavy vehicle, said brake system comprising:
- a control network;
- a brake component;
- a central control unit generating central control signals adapted to control said brake component, the control signals being transmitted to said brake component over said control network;
- and
- a distributed electronic control unit receiving the central control signals, said distributed electronic control unit controlling said brake component in accordance with the central control signals if the central control signals are received during expected time periods, and controlling said brake component in accordance with an alternative control scheme if the central control signals are not received during the expected time periods.
A brake system for a heavy vehicle, said brake system comprising:
- a plurality of brake components;
- at least one vehicle performance sensor;
- a central control unit receiving sensor signals from said at least one vehicle performance sensor and generating central control signals for controlling said plurality of brake components based on the received sensor signals;
- and
- at least one distributed electronic control unit receiving the central control signals, said at least one distributed electronic control unit controlling at least one of said brake components in accordance with at least one of the central control signals if the at least one of the central control signals directed to control of the at least one of said brake components is received during expected time periods, and controlling the at least one of said brake components in accordance with an alternative control scheme if the at least one of the central control signals directed to control of the at least one of said brake components is not received during the expected time periods.
