Abstract
A distributed vehicle safety system (10) and an associated method provide for connection of a plurality of devices (14). Each of the devices (14) performs a function associated with protection of a vehicle occupant. A communication bus (16) conveys communication for the devices (14). The bus includes first and second conductors (18A and 18B). A first portion (subset K) of the devices (14) are daisy-chain connected, with respect to each other, along one (e.g., 18A) of the conductors of the bus (16). A second portion (subset L) of the devices (14) are connected in parallel across the first and second conductors (18A and 18B) of the bus (16). The second portion (subset L) contains at least one and preferably several devices (14).
