Abstract: A control apparatus for a vehicle is provided. The vehicle includes an engine, a dog clutch and a friction clutch. The dog clutch is configured to transmit power or interrupt transmission of power in a power transmission path that transmits power of the engine to a drive wheel. The dog clutch includes a synchromesh mechanism. The friction clutch is configured to transmit power or interrupt transmission of power in the power transmission path between the engine and the dog clutch. The control apparatus includes: an electronic control unit. The electronic control unit is configured to, when the synchromesh mechanism is operated in order to engage the dog clutch in a state where the vehicle is stopped and the friction clutch is released, increase a rotation speed of the engine as compared to when the synchromesh mechanism is not operated.

Abstract: In engaging (connecting) a dog clutch by operating a synchromesh mechanism, when there occurs an uplock at the time when a first pressing force is caused to act on a hub sleeve, tooth tips of spline teeth of the hub sleeve contact with tooth tips of spline teeth of a synchronizer ring, and these spline teeth cannot be engaged. However, when a second pressing force is caused to act on the hub sleeve, the uplock is easy to be released. In addition, when torque from an engine is caused to act on the hub sleeve, a displacement is caused to occur in a rotation direction between the mutually contacting spline teeth. Thus, the uplock is reliably released.

Abstract: A power transmission system includes a first transmission provided in a first power transmission path, a second transmission provided in a second power transmission path, a first engagement device, a second engagement device, a third engagement device, a fail-safe valve, and an electronic control unit. The third engagement device selectively connects or interrupts one of the first and second power transmission paths. The electronic control unit is configured to, during traveling in a state where the third engagement device is released, output hydraulic pressure commands for simultaneous engagement of the first engagement device and the second engagement device. The electronic control unit is configured to, when it is determined that both the first engagement device and the second engagement device are engaged, prohibit traveling using the one of the first and second power transmission paths which is selectively connected or interrupted by the third engagement device.

Abstract: A controller is configured to obtain a speed ratio equivalent value that is determined by a speed ratio set in a transmission unit, and is configured to control an engine by setting an operating point of the engine such that the operating point in the case where a lockup clutch is engaged and the speed ratio equivalent value is large is lower in an output rotation speed for a predetermined output torque than the operating point in the case where the lockup clutch is engaged and the speed ratio equivalent value is smaller than the large speed ratio equivalent value.
