Gear shift indicator

摘要

A gear shift indicator can reduce bothersome feelings of the driver. The EFI-ECU acquires information about the travelling state of a vehicle, and calculates a target gear shift stage for improving fuel consumption. The EFI-ECU acquires information about a current gear shift stage. The EFI-ECU determines that a gear shift request is generated when the current gear shift stage is different from the target gear shift stage. When the EFI-ECU determines that an AI control is under execution and that the calculated target gear shift stage is a restricted gear shift stage prohibited in the AI control, the EFI-ECU does not present a gear shift indication.

1. A gear shift indicator used in a vehicle having mounted thereon a manual gear transmission capable of performing a manual gear shift, and encouraging gear shift instructions to a driver, the gear shift indicator comprising:
a target gear shift stage setting unit that sets a target gear shift stage in accordance with a vehicle speed and a throttle opening degree of the vehicle, a presentation unit that presents the gear shift instructions facilitating a transition to the target gear shift stage when a current gear shift stage is different from the target gear shift stage set by the target gear shift stage setting unit, and a restriction unit that restricts the current gear shift stage from being transferred to a predetermined gear shift stage in accordance with at least one of a travelling state of the vehicle and road conditions ahead of the vehicle in travelling, wherein (i) the presentation unit is operative to refer to information indicative of the gear shift stage restricted by the restriction unit under a condition that the restriction for a transition to the predetermined gear shift stage is executed by the restriction unit and not to present the gear shift instructions when the target gear shift stage is a gear shift stage restricted by the restriction unit, and (ii) the presentation unit is operative to present the gear shift instructions under the condition that the restriction for the transition to the predetermined gear shift stage is not executed by the restriction unit.
