Title:
MOTIVE POWER TRANSMISSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/123393
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a motive power transmission control device which is provided with a switching mechanism for performing switching to connect and disconnect motive power transmission between a first rotational shaft having a first motive power source and a second motive power source connected thereto, and a second rotational shaft rotating in conjunction with an axle, and which, when the switching mechanism is switched from a disconnected state to a connected state during travel of a vehicle, promptly and accurately switches the adjustment of the rotational frequency of the first rotational shaft. A control unit executes: first rotational frequency control processing for controlling the rotational frequency of the first rotational shaft using at least the first motive power source until the rotational difference becomes a first prescribed rotational difference or smaller; and, after the rotational difference has become the first prescribed rotational difference or smaller as a result of the first rotational frequency control processing, second rotational frequency control processing for controlling the rotational frequency of the first rotational shaft using the second motive power source, which is capable of adjusting the rotational frequency with high accuracy, while controlling the first motive power source to a fixed torque, such that the rotational difference matches a second prescribed rotational difference smaller than the first prescribed rotational difference.
