Title:
TRANSMISSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/042955
Kind Code:
A1
Abstract:
The present invention provides a transmission control device capable of shortening the forward/reverse switching time of a transmission. In a transmission control device for controlling a transmission provided with a forward power transmission mechanism for advancing a vehicle and a reverse power transmission mechanism for reversing the vehicle, the present invention provides the forward power transmission mechanism and the reverse power transmission mechanism with respective driving connectors and driven connectors. The forward power transmission mechanism and the reverse power transmission mechanism are configured to be able to change between a contact state in which the driving connector and the drive connector are pressed together and brought into contact, a retracted state in which the pressing force is released and the connectors are retracted, and an intermediate state for putting the connectors in an intermediate state between the contact state and the retracted state. When controlling the vehicle on the basis of previously generated control details including shifting between forward control and reverse control, while putting either the forward power transmission mechanism or the reverse power transmission mechanism into the contact state and performing either forward control or reverse control, the other power transmission mechanism is controlled to be in the intermediate state.
