Patent attributes
A display pushbuttons system (DPS), network, and methods of using the same. The DPS connects to a vehicle controller area network (CAN) bus accessing and controlling vehicle functions. The DPS includes selectively activatable display pushbuttons. The DPS can be configured to display graphics stored in a memory on the display pushbutton screens. The DPS can be operated in active mode or passive mode. In active mode, a controller on the DPS receives CAN messages from vehicle function CAN nodes and can use that information to update the image, color, or brightness of the corresponding display pushbutton screens. In addition, activating a display pushbutton may alter a vehicle characteristic or function. In passive mode, the DPS control logic is provided elsewhere on the vehicle CAN bus by a node with access to the CAN dbc file and the DPS object so the DPS can be controlled.
