System and method for controlling power transmission mechanism, and utility vehicle

A system for controlling a power transmission mechanism, the system comprising:

• a power transmission mechanism including a rotation shaft, a power transmission gear rotatably fitted to the rotation shaft and locked to the rotation shaft in an axial direction, a dog ring slidably fitted to the rotation shaft in the axial direction and locked to the rotation shaft in a circumferential direction, and a dog clutch provided in the dog ring and the power transmission gear;
• a switching mechanism that moves the dog ring in the axial direction to switch a power transmission state;
• and
• a switching controller that controls operation of the switching mechanism,
• wherein the switching controller
• determines whether the dog clutch becomes in an engaged state in a case of giving a switching command for switching the power transmission state by moving the dog ring to a side of the power transmission gear in the axial direction, and
• causes the dog ring to be moved to a side opposite to the power transmission gear in the axial direction in a case where the dog clutch is determined not to be in the engaged state, and then retries movement of the dog ring to the side of the power transmission gear.
