ABSTRACT:
A vehicle multiplex system includes a multiplex controller mounted in a fuse block of the vehicle. Both power buses and control buses radiate from the fuse block, and the control buses interconnect the controller with respective input and output units distributed about the vehicle. Preferably, the controller selects one of the control buses as an active bus at any given time and isolates the remaining control buses both from the active control bus and from the controller. In this way, system reliability is improved, and electromagnetic interference is reduced. By positioning the multiplex controller in the fuse block, wiring requirements for the multiplex system are simplified and the multiplex system is more readily integrated into the electrical system of the vehicle.
