Title: INDICATOR CONTROL SYSTEM AND VEHICLE
Abstract: [0001]    An indicator control system includes an indicator (36) configured to show a rotational speed of an internal combustion engine (13), and a controller (11) configured to control an indicated rotational speed, which is the rotational speed to be shown by the indicator (36). The controller (11) is configured such that, during a specific period in which the rotational speed of the internal combustion engine (13) is reduced from a first rotational speed to a rotational speed lower than the first rotational speed and then increased to a second rotational speed higher than the first rotational speed, the controller (11) increases the indicated rotational speed to the second rotational speed without reducing the indicated rotational speed from the first rotational speed to the rotational speed lower than the first rotational speed.

Claims: number: 1
text: An indicator control system comprising:
number: 2
text: The indicator control system according to claim 1, wherein the controller (11) is configured to keep the indicated rotational speed at the first rotational speed and then increase the indicated rotational speed to the second rotational speed in the specific period.
number: 3
text: The indicator control system according to claim 1, wherein the controller (11) is configured to increase the indicated rotational speed from the first rotational speed at a predetermined increase rate in the specific period.
number: 4
text: A vehicle (10) comprising:
number: 5
text: The vehicle (10) according to claim 4, further comprising a rotating electrical machine (14), wherein
the continuously variable transmission (20) is a planetary gear mechanism provided between the internal combustion engine (13), the rotating electrical machine (14), and the driving wheel (24).
number: 6
text: The vehicle (10) according to claim 4 or 5, wherein the internal combustion engine (13) includes a turbocharger (47).
number: 7
text: The vehicle (10) according to claim 6, wherein
the specific period is started when the turbocharger is actuated,
the first rotational speed is a rotational speed of the internal combustion engine (13) at a start of the actuation of the turbocharger, and
the controller (11) is configured such that, when the rotational speed of the internal combustion engine (13) is lower than the first rotational speed in the specific period, the controller (11) sets the indicated rotational speed equal to or higher than the first rotational speed.
number: 8
text: The vehicle (10) according to any one of claims 4 to 6, wherein
the specific period is started when an accelerator operation amount is increased,
the first rotational speed is a rotational speed of the internal combustion engine (13) at a start of the increase in the accelerator operation amount, and
the controller (11) is configured such that, when the rotational speed of the internal combustion engine (13) is lower than the first rotational speed in the specific period, the controller (11) sets the indicated rotational speed equal to or higher than the first rotational speed.
number: 9
text: The vehicle according to any one of claims 4 to 8, wherein the controller (11) is configured such that, after the rotational speed of the internal combustion engine (13) reaches the indicated rotational speed along with acceleration of the vehicle (10) in the specific period, the controller (11) sets the indicated rotational speed to the rotational speed of the internal combustion engine (13).
