ELECTRICALLY-DRIVEN CONTROL DEVICE FOR VEHICLE

Japanese Patent JP2016156454

A

PROBLEM TO BE SOLVED: To provide an electrically-driven control device for a vehicle which makes a relatively great impulse load unlikely to occur in an engagement part between an engage member in a lock mechanism and an engaged part at the moment when the engage member and the engaged part are engaged, and shortens the time required from "start of electrification amount decrease control" to "engagement of both the engage member and the engaged part".SOLUTION: The device transmits a motive force that is generated by an electric motor MTR to a pressing member PSN and generates a pressure of the pressing member PSN to a friction member MSB. The device comprises a lock mechanism LOK. In LOK, the "electrification amount decrease control" is performed for decreasing the amount of electrification to the MTR in the state where an engage member TSU is maintained at an engageable position, an engaged part RCH is moved in a pressure decrease direction and TSU is engaged with RCH, thereby providing a lock state (where RCH is disabled from being moved in the pressure decrease direction). During the electrification amount decrease control, the electrification amount is first decreased at a large decrease incline and then decreased at a small decrease incline.SELECTED DRAWING: Figure 2
