Abstract
A multi-sensor module (10) includes a housing (12) with a plurality of vehicle operating condition sensors (S.sub.1 -S.sub.N) mounted therein and a signal processing circuit (20, 26, 30) also mounted therein which receives sensor signals provided by the plurality of sensors (S.sub.1 -S.sub.N). The signal processing circuit (20, 26, 30) is operable to produce at an output thereof (38) a time-division multiplexed signal representative of the various sensor signals according to a vehicle data bus communications protocol. The signal processing circuit output is connected to an electrical connector (36) adapted for connection to an existing vehicle data bus (18) which is further connected to a vehicle control computer (16). The signal processing circuit (20, 26, 30) is accordingly operable to broadcast on the vehicle data bus (18) sensor information provided by each of the sensors (S.sub.1 -S.sub.N) mounted within the module (10).
