摘要 |
Restriction of hunting in the gear ratio of an electronically-controlled continuously variable transmission (ECVT) for a vehicle. A gear ratio change mechanism has a crankshaft as an input shaft, an output shaft and a motor. The motor continuously varies the gear ratio between the crankshaft and the output shaft. An electronic control unit (ECU) performs feedback control of the gear ratio to achieve a target gear ratio. The ECU reduces an output of the motor when a hunting state of the gear ratio is detected.
