Title:
MOTIVE POWER TRANSMISSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/124220
Kind Code:
A1
Abstract:
[Problem] To provide a motive power transmission control device which is capable of reliably achieving gear engagement in a transmission using non-synchronous transmission. [Solution] This motive power transmission control device is applicable to a vehicle provided with a non-synchronous transmission system having at least two speeds. Rotational frequency information of an idling gear serving as a member to be engaged and rotational frequency information of a sleeve serving as an engagement member are acquired, one rotational frequency which can be changed by a motive power source is set as a synchronizing-side rotational frequency, and another rotational frequency is set as a synchronized-side rotational frequency. After a gear change request is present and a state in which motive power transmission is released is entered, an engagement operation is performed such that the synchronizing-side rotational frequency is changed by the motive power source, the rotational difference with respect to the synchronized-side rotational frequency is made to match a prescribed rotational difference, and a transition to a motive power transmission state via a contact state is achieved. If a prescribed time elapses after the transition to the contact state, control is implemented to induce the transition to the motive power transmission state, while implementing control in which the symbol of the prescribed rotational difference is inverted, and the rotational difference is made to match a prescribed rotational difference obtained by inverting the symbol.
