Document Type and Number:
WIPO Patent Application WO/2016/159124
Kind Code:
A1
Abstract:
Desired is a controlling device for a vehicle driving device that can determine the failure of an engaging device to engage when a transmission device is shifted into a neutral state and the rotational speed of the driving power source drops. A controlling device (30) for a vehicle driving device (1): releases a target engaging device while maintaining the engagement of non-target engaging devices in order to shift the transmission from a state in which the vehicle is traveling and a target gear ratio, which is the gear ratio formed by the target engaging device engaging with a non-target engaging device, is formed to the neutral state in which no gear ratio is formed in the transmission (#02); and determines the failure of the target engaging device to engage (#02, #07) on the basis of changes in the rotational speed of an input member when the rotational speed of the driving power source is further reduced (#04, #06).
