The invention discloses a bus controller for an automobile steering column. The bus controller is characterized in that the bus controller is provided with an LIN transceiver, the LIN transceiver receives control information of a combination switch and multifunctional steering wheel keys and then sends the control information to a microprocessor, and a signal processing circuit collects signals of a loudspeaker and a steering wheel gear shifting sheet and sends the signals to the microprocessor; after collecting all the signals, the microprocessor packages the signals into a CAN signal frame message, and the CAN signal frame message is sent to a CAN bus network through a CAN transceiver to be provided for other controllers. By the adoption of the structure, the cost and topological complexity of wire harnesses nearby the steering column are substantially lowered, the number of butt joint terminals and plug-in components is reduced, and the number of wires is 20% that of existing wires; expansibility is improved, the number of restrictions of the number of connectors, layout space and the like is reduced, and function extension is facilitated; the diagnostic function is added to key loops of the combination switch, the steering wheel keys, an angle sensor, the gear shifting sheet and the like, and malfunction elimination efficiency is improved.
