Programmable multi-function switch and display

摘要

A multi-function, programmable switch display unit is used to control vehicle operation parameters in a heavy duty over-the-road truck. Several switch screens, each showing a set of related truck parameters can be selectively displayed on a display screen. A matrix of pressure sensitive switches overlays the display screen with cut-outs through which items on the display screen can be viewed. A display controller receives input from the pressure sensitive switches and maps them to the correct truck function and causes appropriate control actions to be taken.
