Abstract
A control system for a meshing type engagement mechanism includes a meshing type engagement mechanism and an electronic control unit. The electronic control unit is configured to allow a fluid chamber to be filled with a fluid by putting a switching valve into a cut-off state after respective dog teeth mesh with each other by a second member reaching a predetermined position determined in advance in response to a fluid pressure of the fluid chamber such that the second member is pressed in the direction in which the second member is separated from a first member by a release force depending on the torque transmitted between a surface of a first tooth and a surface of a second tooth, the fluid pressure of the fluid chamber is increased, and an engagement state between the first member and the second member is maintained by the fluid pressure which is increased.
