Abstract:
An actual slip amount (S) of a torque converter is calculated by subtracting an actual input shaft rotational speed (Nr) of an automatic transmission from an engine rotational speed (Ne), which is the rotational speed of a crankshaft. Then, an engine rotational speed for display (Nd) is calculated by adding a slip amount adjusted for display (Sp), which is obtained by applying a predetermined correction process to the actual slip amount (S) to the actual input shaft rotational speed (Nr). The above described correction process may be a first-order-lag filter processing, for example. Thus, even when the actual slip amount (S) temporarily increases or decreases, a temporary increase or decrease in the engine rotational speed for display (Nd) may be suppressed. In other words, fluctuation or variation in the engine rotational speed for display (Nd) is suppressed. Further, Further, it is possible to provide the driver with a visually excellent direct-feeling display of engine speed Nd without impairing the drivability.

Claim (Index 1):
An engine rotational speed display device mounted on a vehicle in which a driving force of an internal combustion engine is transmitted to a driving wheel via a torque converter and an automatic transmission, wherein a display engine rotational speed for display is calculated by adding a display slip amount to an input shaft rotational speed of the automatic transmission, wherein the display slip amount is calculated by applying a predetermined correction process to an actual slip amount in the torque converter so as to be equal to or less than the actual slip amount, and wherein the correction process is applied such that fluctuations in the display slip amount will be less than fluctuations in the actual slip amount.
