<p>The present invention relates to intelligent fuse box ( 1 ) for a vehicle's multiplex power distribution system, the fuse box including outputs ( 3 ) for driving the vehicle's functional components/actuators and/or cable buses ( 11-13 ) equipped with intelligent_nodes ( 14 ), the latter in turn having outputs for driving functional components/actuators ( 15 ), and further including means serving fuse functions between the outputs ( 3; 11-13 ) and the vehicle's power supply bus ( 12 ). The fuse-function means are controlled solid-state switches ( 4 ). The fuse box ( 1 ) includes inputs ( 5 ) for receiving messages controlling the ON/OFF state of solid-state switches ( 4 ) and a microprocessor ( 6 ), the latter controlling the solid-state switches ( 4 ) based on a program stored in the microprocessor memory ( 7 ) and on current limits predetermined in configuration data ( 8 ). In addition to the actual fuse functions, the controlled operation of the solid-state switches offer a plurality of auxiliary functions such as rush current limiting, programmable reconfiguration of current limits, dynamic fuse functions (e.g., to implement a low-current Asleep mode in a parked vehicle) and measurement of system overall load current.</p> |
