Engine rotational speed display device

摘要

An engine rotational speed display device includes: an engagement state determination module that determines an engagement state of a lock-up clutch; a target rotational speed setting module that sets a target turbine rotational speed according to a selected gear stage; a rotational speed for display selection unit that selects an engine rotational speed as a rotational speed for display when the lock-up clutch is not engaged and selects the target turbine rotational speed as the rotational speed for display when the lock-up clutch is engaged; a time measuring module that measures an elapsed time since a gear shift operation is received; and a rotational speed for display limiting module that limits a variation in the rotational speed for display per unit of time according to the elapsed time when the target turbine rotational speed is selected as the rotational speed for display.

1. An engine rotational speed display device for a vehicle equipped with a continuously variable transmission that includes a manual transmission mode and that converts and outputs a drive force that is outputted from an engine and transmitted via a torque converter with a lock-up clutch, the manual transmission mode allowing a gear shift according to a gear shift operation of a driver, the engine rotational speed display device comprising:
an engagement state determination module that determines an engagement state of the lock-up clutch; an engine rotational speed acquisition module that acquires a rotational speed of the engine; a target rotational speed setting module that sets a target turbine rotational speed of a turbine liner included in the torque converter according to a selected gear stage; a rotational speed for a display selection module that selects the engine rotational speed as a rotational speed for display when the lock-up clutch is not engaged and selects the target turbine rotational speed as the rotational speed for display when the lock-up clutch is engaged; a display unit that displays a rotational speed according to the rotational speed for display; and wherein the rotational speed for display is limited such that a variation in the rotational speed for display per unit of time falls within different variation limiting values based on a comparison between a predetermined time and an elapsed time since the gear shift operation is received.
