<p>The invention relates to a display system for a vehicle of the type comprising a display unit for displaying graphics and text to an operator of the vehicle, touch switch entry means for entry of desired function information by the operator and generation of touch input signals, discrete switch entry means for entry of additional function information by the operator and generation of discrete signals, and a display controller for controlling the display system operations by selective partitioning of system functions. According to the invention the display system is characterised in that the display controller comprises an input/output (I/O) channel, an interprocessor data link for transferring data and commands between data processors, a master microprocessor for issuing control signals and responding to control signals representative of selected system functions, storage means associated with the master microprocessor for storing master data and commands and a master control program to control master functions in the system, the master functions including control of graphics and text for display on the display unit in response to the touch switch means and the discrete switch means, and a slave microprocessor for issuing and responding to control and data signals involving communication with the master microprocessor via the input/output channel and the interprocessor data link, and storage means associated with the slave microprocessor for storing slave data and commands and a slave control program to control slave functions in the system, the slave functions including control and monitoring of communications internally within the display controller and externally by the display controller.</p> |
