Abstract:
When an automatic transmission shift start condition is satisfied, an electronic control unit calculates a meter target rotational speed of an engine by adding a correction amount corresponding to the state of a torque converter to a turbine rotational speed corresponding to a post-shift gear stage, and makes a meter display rotational speed follow after the meter target rotational speed, fixes the correction amount to a value obtained at the time of shift start determination, when immobilization conditions including that the shift start condition for a downshift is satisfied and that the engine is driven are satisfied. When actual rotational speed display conditions are satisfied, it can be predicted that differences between an engine rotational speed and a turbine rotational speed before and after shifting are large, and so the electronic control unit sets a current engine rotational speed as the meter target rotational speed or ends the control.
