STEUERVORRICHTUNG FÜR EINEN ÜBERTRAGUNGSMECHANISMUS

摘要

The invention provides a transmission which can estimate heat value of a motor with a simple structure. The motorcycle (1) is provided with a transmission (20). The transmission (20) has a transmission mechanism (20a) and an ECU (7). The transmission mechanism (20a) includes: a crankshaft (11) as an input shaft, a driven shaft (27) as an output shaft, and an electric motor (30). The electric motor (30) changes continuously the transmission ratio between the crankshaft (11) and the driven shaft (27). The ECU (7) estimates the heat value of the motor (30) from the rate of change in the transmission ratio.
