The controller is capable of receiving signals transmitted from the sensors and prioritizing vehicle operating conditions indicated by received signals according to predetermined criteria. The system further includes a display screen adapted to display warning signals according to signals received from the vehicle display controller. The display screen arranges the displayed warning signals according to one of a plurality of display masks. The display mask is determined by the number of displayed warning signals. The display mask has a first warning signal display area for displaying warning signals having priorities greater than a predetermined level and a second warning signal display area for displaying warning signals having priorities less than the predetermined level. ## Claims ### Claim 1 A vehicle display system adapted to display one or more warning signals representing vehicle operating conditions, the display system comprising: (a) a plurality of sensors mounted to a vehicle for sensing vehicle operating conditions; (b) a vehicle display controller in communication with the plurality of sensors, the controller being capable of receiving signals transmitted from the plurality of sensors and prioritizing vehicle operating conditions indicated by received signals according to predetermined criteria; and (c) a display screen adapted to display warning signals according to signals received from the vehicle display controller, each warning signal indicating a vehicle operating condition, the display screen being adapted to arrange the displayed warning signals according to one of a plurality of display masks, the display mask being determined by the number of displayed warning signals, wherein the display mask has a first warning signal display area for displaying warning signals having priorities greater than a predetermined level and a second warning signal display area for displaying warning signals having priorities less than the predetermined level. ### Claim 2 (depends on 1) The vehicle display system of claim 1, wherein warning signals displayed in the first warning signal display area are located relative to other warning signals displayed in the first warning signal display area according to the relative priority of each warning signal. ### Claim 3 (depends on 2) The vehicle display system of claim 2, wherein the first warning signal display area is capable of displaying a predetermined number of warning signals at a particular time, said first warning signal display area displaying the warning signals having higher priority among active warning signals when a number of active warning signals is greater than the predetermined number of warning signals and not displaying warning signals having lower priority among active warning signals. ### Claim 4 (depends on 3) The vehicle display system of claim 3, wherein the system further includes a scrolling means, said scrolling means adapted to sequentially display each active warning signal on the display when the number of active warning signals is greater than the predetermined number of warning signals. ### Claim 5 (depends on 1) The vehicle display system of claim 1, wherein at least one of the displayed warning signals is selectively removable from the display when the vehicle is stationary. ### Claim 6 (depends on 5) The vehicle display system of claim 5, wherein the at least one displayed warning signal is not selectively removable from the display when the vehicle is moving. ### Claim 7 (depends on 1) The vehicle display system of claim 1, wherein warning signals are displayed in a color determined according to the priority of the indicated operating condition. ### Claim 8 (depends on 7) The vehicle display system of claim 7, wherein warning signals having priorities greater than the predetermined level are displayed in red and warning signals having priorities less than the predetermined level are displayed in yellow. ### Claim 9 (depends on 1) The vehicle display system of claim 1, wherein a newly sensed condition initiates a warning cycle lasting a predetermined amount of time, a warning signal being added to the first warning signal display area during the warning cycle. ### Claim 10 (depends on 9) The vehicle display system of claim 9, wherein the added warning signal continuously flashes on and off during the warning cycle. ### Claim 11 (depends on 9) The vehicle display system of claim 9, wherein the display emits a warning sound during the warning cycle. ### Claim 12 (depends on 1) The vehicle display system of claim 1, wherein the vehicle display controller is adapted to receive data bus messages from an electronic system installed in the vehicle, the data bus messages being indicative of at least one vehicle operating condition. ### Claim 13 A method for displaying vehicle operating conditions on a display screen, the method comprising: (a) receiving a signal from a sensor indicative of a vehicle operating condition; (b) prioritizing the vehicle operating condition according to a predetermined criteria; (c) displaying a warning signal representing the vehicle operating condition on the display screen, the warning signal being displayed in a color according to the priority of the operating condition, the display screen having a layout selected from a plurality of layouts, the layout being determined according to the number of warning signals being displayed and changes as the number of displayed warning signals changes, wherein displayed warning signals of a first color are displayed in a first warning signal display area of the display screen, and warning signals of a second color are displayed in a second warning signal display area of the display screen. ### Claim 14 (depends on 13) The method of claim 13, wherein the step of displaying a warning signal further includes positioning warning signals displayed in the first warning signal display area relative to other warning signals displayed in the first warning signal display area according to the relative priority of each warning signal. ### Claim 15 (depends on 13) The method of claim 13, wherein at least one displayed warning signal is selectively removable from the display when the vehicle is stationary. ### Claim 16 (depends on 15) The method of claim 15, wherein the at least one selectively removable warning signal is not selectively removable when the vehicle is moving. ### Claim 17 (depends on 13) The method of claim 13, wherein the step of displaying a warning signal further includes initiating a warning cycle lasting a predetermined amount of time, and a warning signal is added to the first warning signal display area during the warning cycle. ### Claim 18 (depends on 17) The method of claim 17, wherein the added warning signal continuously flashes on and off during the warning cycle. ### Claim 19 (depends on 17) The method of claim 17, wherein the step of displaying a warning signal further includes emitting a warning sound during the warning cycle.
