Display control apparatus for meter
First Claim
1. A display control apparatus for a meter, the meter being mounted on a vehicle, the vehicle including an engine and an automatic transmission, the meter being configured to display a rotation speed of the engine, the display control apparatus comprising:
- a rotation sensor configured to detect a rotation speed of the engine; and
an electronic control unit configured to;
(i) during a shift of the automatic transmission, calculate an estimated engine rotation speed estimated based on a gear position after the shift;
(ii) during the shift of the automatic transmission, control the meter such that the meter displays the estimated engine rotation speed; and
(iii) when the electronic control unit determines that the engine has changed from a driving state where the engine drives the vehicle to a driven state where the engine is driven by the vehicle during the shift of the automatic transmission or when the electronic control unit determines that the engine has changed from the driven state to the driving state during the shift of the automatic transmission, control the meter, during the shift of the automatic transmission after the change has been determined, so that the rotation speed of the engine, displayed on the meter, is changed from the estimated engine rotation speed which is displayed during a first portion of the shift of the automatic transmission regardless of whether a lockup clutch of a torque converter connected between the engine and the automatic transmission is in a lockup state or is not in the lockup state, to the rotation speed of the engine detected by the rotation sensor, which is displayed during a portion of the shift of the automatic transmission after the first portion.

Abstract
A display control apparatus for a meter is provided. The display control apparatus includes a rotation sensor and an electronic control unit. The electronic control unit is configured to: (i) during a shift of the automatic transmission, calculate an estimated engine rotation speed estimated on the basis of a gear position after the shift; (ii) during the shift of the automatic transmission, control the meter such that the meter displays the estimated engine rotation speed; and (iii) when the engine has changed from a driving state to a driven state during the shift or the engine has changed from the driven state to the driving state during the shift, control the meter such that the rotation speed of the engine, displayed on the meter, is changed from the estimated engine rotation speed to the rotation speed of the engine, detected by the rotation sensor.
