Gear change instruction apparatus and method

摘要

The present invention relates to a gear change instruction apparatus for a friction clutch device having a driving plate and a driven plate and for a transmission having a plurality of gear positions, the gear change instruction apparatus being configured to generate an instruction to change the gear position of the transmission and comprising: an estimator configured to estimate a calorific value by friction between the driving plate and the driven plate in the friction clutch device; a determiner configured to determine whether a change in the gear position of the transmission (43) is required based on the calorific value estimated by the estimator; and a notifier configured to make a notification to an operator of the gear change instruction apparatus to change the gear position of the transmission when the determiner determines that the gear position of the transmission must be changed, and to a gear change instruction method.
