SETTING-OFF ASSISTANCE DEVICE

WIPO Patent Application WO/2022/024216

A1

Provided is a setting-off assistance device that can reduce the consumption of power during a stop, and reduce any discomfort when setting off. This setting-off assistance device comprises: a first gear mechanism (20) that transmits, to an output shaft, the torque of a first shaft (14) to which the torque of a first drive device (12) is transmitted; a second gear mechanism (30) that transmits, to the output shaft, at a lower reduction ratio than the reduction ratio of the first gear mechanism, the torque of a second shaft (15) positioned coaxially with respect to the first shaft, the torque of a second drive device (13) being transmitted to the second shaft; a first clutch (40) that transmits/interrupts driving power between the first shaft and the second shaft; a second clutch (23) comprising a one-way clutch that transmits, to the output shaft, the rotation of the first gear mechanism when the vehicle is moving forward; and a control device (50) that operates the first clutch. At least one of the first drive device and the second drive device is a motor, and the control device engages the first clutch when the vehicle is at or below a prescribed speed and is on an uphill slope.
