Abstract:
A system for monitoring vehicle subsystems, the system comprising:a vehicle comprising an antilock braking system and an antilock braking system interface, responsive to the antilock braking system, which produces a data signal representing a status of the antilock braking system, a power bus which distributes electrical power to the vehicle, and power line carrier communicating means, responsive to the antilock braking system interface, for producing a data communications signal on the power bus from the data signal, wherein the power line carrier communicating means comprises spread spectrum signal producing means, responsive to the antilock braking system, for producing a spread spectrum data communications signal on the power bus from the data signal; and status determining means, responsive to the power bus, located remote from the vehicle for determining the status of the antilock braking system from the data communications signal, wherein the status determining means comprises means for determining the status of the antilock braking system from the spread spectrum data communications signal.
