The present invention relates to intelligent fuse box () for a vehicle's multiplex power distribution system, the fuse box including outputs () for driving the vehicle's functional components/actuators and/or cable buses () equipped with intelligent_nodes (), the latter in turn having outputs for driving functional components/actuators (), and further including means serving fuse functions between the outputs () and the vehicle's power supply bus (). The fuse-function means are controlled solid-state switches (). The fuse box () includes inputs () for receiving messages controlling the ON/OFF state of solid-state switches () and a microprocessor (), the latter controlling the solid-state switches () based on a program stored in the microprocessor memory () and on current limits predetermined in configuration data (). 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.

Intelligent fuse box for the power distribution system of a vehicle

A current distribution system for a vehicle, wherein a high-level data bus ( ) and a low-level data bus ( ) are consistent with different protocols and are in a data transfer communication with each other by way of an adapter ( ). Intelligent nodes ( ) associated with at least the low-level data bus ( ) are provided with a standard kernel software and with node-specific configuration files, whereby the kernel software is adapted to represent the desired functions of a node, including the reception and transmission of control messages, as well as a controlled current supply to electrical devices ( ) in a vehicle. The node configuration files are stored as a system configuration in the adapter ( ), from which a proper node configuration file can be loaded into a given node ( ).

Current distribution system for a vehicle

A procedure is disclosed for determining the message identifiers in a control area network CAN data transmission network of an elevator system where message identifiers are used in the transmission of messages. Each node in the network monitors the data transmissions in the network and stores the other message identifiers in use by the other nodes. When selecting a message identifier, the node makes use of a random number to select an unused identifier from an identifier table.
