ABSTRACT:
A vehicle display system comprises a plurality of display units and a controller unit. Each display unit has a receiver for receiving measured data indicating a state of the vehicle, and a driver controller for controlling an indicator driver according to the measured data. The controller unit has a transmitter for transmitting the measured data to the plurality of display units and a transmitter controller for controlling the transmission. Each display unit further comprises a generator for generating response data indicating a state of the indicator driver and a transmitter for transmitting the response data to the controller unit. The controller unit further comprises a receiver for receiving each response data and a comparator for comparing each response data with the measured data to judge whether each indicator driver is controllable or not. Further, the transmitter controller controls according to a judged result.
