Abstract:
Aspects of the present invention are directed at an enhanced display for presenting tachometer information. In accordance with one embodiment, a method is provided that causes an electronic control unit associated with a dashboard display to present the current engine speed (e.g. RPM) relative to an optimal range in which fuel efficiency is maximized. More specifically, the method includes obtaining a set of tachometer data at the electronic control unit that defines the lower and upper limits of the optimal range in which fuel efficiency is maximized. Periodically, the current engine speed may be obtained by the electronic control unit associated with the dashboard display. Then, the method causes the current engine speed to be presented on the graphical display relative to the lower and upper limits of the optimal range.
