Abstract:
A tachometer for a motor vehicle comprising, in combination:a display adapted to produce an observable indication of a current rpm value for a current gear and an observable indication of at least one predicted rpm value for a different gear which is a prediction of what the current rpm will become upon changing the current gear to the different gear; wherein the display is adapted to simultaneously produce the of observable indication of the current rpm value and the observable indication of the at least one predicted rpm value; wherein the current rpm value is different than the at least one predicted rpm value when the motor vehicle is moving and the current gear is different than the different gear; a controller operably connected to the display and adapted to provide signals representing the current rpm value for the current gear and the at least one predicted rpm value for the different gear to the display; at least one sensor operably connected to the controller and adapted to provide signals representing at least the current rpm and the current gear; and wherein the controller is adapted to determine the at least one predicted rpm value using predetermined performance information and the signals representing at least the current rpm and the current gear.
