Vehicle, control apparatus for vehicle, and control method for vehicle

A control method for a vehicle, the vehicle including a dog clutch and an electronic control unit, the dog clutch including a synchromesh mechanism, the synchromesh mechanism including a sleeve and a synchronizer ring, the sleeve being pressed against the synchronizer ring by a predetermined pressing force to be synchronized with the synchronizer ring when engagement of the dog clutch is determined, and then the dog clutch being engaged, the control method comprising:

• (a) in engaging the dog clutch, causing, by the electronic control unit, a first pressing force to act on the sleeve, the first pressing force being required to engage the sleeve with the synchronizer ring;
• (b) after causing the first pressing force to act on the sleeve, causing, by the electronic control unit, a second pressing force to act on the sleeve, the second pressing force being smaller than the first pressing force, a synchronized state of the sleeve with the synchronizer ring being kept by the second pressing force under a condition that no torque is input to the sleeve;
• and
• (c) while causing the second pressing force to act on the sleeve, inputting, by the electronic control unit, torque from a driving force source of the vehicle to the sleeve.

A vehicle comprising:

• a dog clutch including a synchromesh mechanism, the synchromesh mechanism including a sleeve and a synchronizer ring, the sleeve being pressed against the synchronizer ring by a predetermined pressing force to be synchronized with the synchronizer ring when engagement of the dog clutch is determined, and then the dog clutch being engaged;
• and
• an electronic control unit configured to:
• (a) in engaging the dog clutch, cause a first pressing force to act on the sleeve, the first pressing force being required to engage the sleeve with the synchronizer ring,
• (b) after causing the first pressing force to act on the sleeve, cause a second pressing force to act on the sleeve, the second pressing force being smaller than the first pressing force, a synchronized state of the sleeve with the synchronizer ring being kept by the second pressing force under a condition that no torque is input to the sleeve, and
• (c) while causing the second pressing force to act on the sleeve, input torque from a driving force source of the vehicle to the sleeve.
