AUTONOMOUS VEHICLE INTERFACE USING BUS IMPEDANCE TO IDENTIFY CONTROL UNITS, AND ASSOCIATED SYSTEMS AND METHODS

Systems and methods that facilitate identifying and controlling the systems and subsystems in a vehicle to enable autonomous operation of the vehicle are disclosed. An autonomous vehicle interface (AVI) (the "AVI control system") can interface with and control the system of the vehicle, thereby enabling control of the vehicle as a whole. Electronic control units may be associated with each of the systems and subsystems in the vehicle, and the AVI may interface with and control these electronic control units over a shared data bus. In order to control particular electronic control units, the systems and methods provide for sampling data packets transmitted by the electronic control units on the shared data bus, measuring the impedance of the shared data bus when data packets are being transmitted, and identifying particular electronic control units based on the measured impedance.
