A control system for a meshing type engagement mechanism, comprising: the meshing type engagement mechanism including a first member, a second member, a fluid chamber, and a switching valve, the first member including a plurality of first dog teeth protruding in an axial direction, the first dog teeth being placed at regular intervals in a circumferential direction of the first member, the second member including a plurality of second dog teeth protruding in the axial direction, the second dog teeth being placed at regular intervals in a circumferential direction of the second member, the second dog teeth being configured to be inserted between the first dog teeth, the fluid chamber being configured to allow the second member to be moved to the first member side by an operating force attributable to a supply of a fluid such that the first dog teeth and the second dog teeth mesh with each other, the switching valve being configured to switch between a communicating state where the fluid is supplied to the fluid chamber and a cut-off state where the supply of the fluid to the fluid chamber is stopped and the fluid chamber is filled with the fluid, and a tooth surface of the first dog teeth and a tooth surface of the second dog teeth transmitting a torque in contact with each other being inclined surfaces such that a release force in a direction in which the first member and the second member are separated from each other in the axial direction is generated in response to the torque; and an electronic control unit configured to control the supply and stopping of the supply of the fluid to the fluid chamber by the switching valve, the electronic control unit being configured to allow the fluid chamber to be filled with the fluid by putting the switching valve into the cut-off state after the respective dog teeth mesh with each other by the 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 the first member by the release force depending on the torque transmitted between the tooth surface of the first tooth and the tooth surface of the 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, characterized in that the switching valve is a normally closed-type electromagnetic valve that is configured to be opened when energized, wherein the engagement state between the first member and the second member is released by energizing the switching valve such that the switching valve is opened and the fluid in the fluid chamber flows out. the meshing type engagement mechanism including a first member, a second member, a fluid chamber, and a switching valve, the first member including a plurality of first dog teeth protruding in an axial direction, the first dog teeth being placed at regular intervals in a circumferential direction of the first member, the second member including a plurality of second dog teeth protruding in the axial direction, the second dog teeth being placed at regular intervals in a circumferential direction of the second member, the second dog teeth being configured to be inserted between the first dog teeth, the fluid chamber being configured to allow the second member to be moved to the first member side by an operating force attributable to a supply of a fluid such that the first dog teeth and the second dog teeth mesh with each other, the switching valve being configured to switch between a communicating state where the fluid is supplied to the fluid chamber and a cut-off state where the supply of the fluid to the fluid chamber is stopped and the fluid chamber is filled with the fluid, and a tooth surface of the first dog teeth and a tooth surface of the second dog teeth transmitting a torque in contact with each other being inclined surfaces such that a release force in a direction in which the first member and the second member are separated from each other in the axial direction is generated in response to the torque;
