Multiple rpm indicating tachometer for motor vehicles

A tachometer for a motor vehicle includes a controller adapted to provide a current rpm value at a current gear which is engaged and at least one predicted rpm value at a different gear which is not currently engaged. A display is operatively connected to the controller and is adapted to produce an...

Zusammenfassung:	A tachometer for a motor vehicle includes a controller adapted to provide a current rpm value at a current gear which is engaged and at least one predicted rpm value at a different gear which is not currently engaged. A display is operatively connected to the controller and is adapted to produce an observable indication of the current rpm value and an observable indication of the predicted rpm value. By displaying predicted rpm values for different gears, the motor vehicle operator can easily see the effect of shifting gears so that the gears can be shifted in a manner to obtain optimum performance of the motor vehicle. The display preferably produces an observable indication of the current gear number near the current rpm value and an observable indication of the different gear number near the observable indication of the predicted rpm value.
