Abstract: A control apparatus for a vehicle that includes (i) a first engagement device configured to connect and disconnect an engine and an electric motor to and from each other, and (ii) a second engagement device configured to connect and disconnect the electric motor and drive wheel to and from each other. In event of a failure of the second engagement device, the control apparatus is configured to forcibly bring the second engagement device into an engaged state and to bring the first engagement device into an engaged state, so as to cause the vehicle to perform a limp-home running in a first running mode in which the vehicle runs using at least the engine. When a running speed of the vehicle becomes lower than a predetermined low-speed threshold value during the limp-home running, the control apparatus is configured to bring the first engagement device into a released state.

Abstract: A transmission control apparatus for controlling a vehicle's transmission. The apparatus includes (i) a control motor mechanically connected to the transmission's selector drum and is actuable to rotate the selector drum, (ii) a torque sensor which senses torque applied to the selector drum by the control motor, (iii) a controller configured to control the control motor based on signals received from the torque sensor to control the engagement/disengagement of the dog clutches; and (iv) a cam indexer connected to the selector drum. The cam indexer includes (i) a cam sprocket having one gear detent corresponding to each of gear engagement position of the selector drum, and one neutral detent corresponding to each neutral position of the selector drum, and (ii) a cam follower that engages with the gear detents and biases the selector drum into either a corresponding gear engagement position or a corresponding neutral position.

Abstract: A control method for controlling gear-shifting and lock-up of an engine clutch in a hybrid vehicle includes: detecting a kickdown shift by a driver while the hybrid vehicle is driving in an electric vehicle mode; starting gear-shifting when the kickdown shift is detected; controlling a difference between an engine speed and a motor speed to be equal to or less than a first reference value; synchronizing the engine speed and the motor speed through an engine speed control; performing torque blending by locking up the engine clutch when the synchronization is completed; and ending the gear-shifting when a target required torque is reached through the torque blending.

Abstract: Disclosed are a hybrid electric vehicle having a transmission without a reverse (R) stage and capable of coping with a situation in which a connection state between a motor and an engine is unknown, and a control method thereof. The method includes, if a preset condition is satisfied in a situation where a state of an engine clutch is unknown, driving any one of a first driving source disposed at one end of the engine clutch and a second driving source disposed at the other end of the engine clutch, determining whether the other one of the first driving source and the second driving source rotates, and determining whether the engine clutch is opened depending on the determination result.
