摘要： When neutral control is started by placing a CVT drive clutch in a semi-engaged state while a vehicle is decelerating in a state where a second power transmission path is established, a clutch mechanism that is semi-engaged in neutral control while the vehicle is decelerating is changed from the CVT drive clutch to a forward clutch before a stop of the vehicle, so it is possible to continue the neutral control until a stop of the vehicle. At a stop of the vehicle, a power transmission path is already changed to a first power transmission path that establishes a gear ratio (EL) higher than a highest gear ratio (γmax) that can be established by the second power transmission path. Thus, right after a stop of the vehicle, it is possible to execute idle stop control.

摘要： A control apparatus for a vehicle drive-force transmitting apparatus including a continuously-variable transmission mechanism whose gear ratio is calculated based on a detected value of an input rotational speed of the transmission mechanism and a processed output-rotational-speed value that is a detected value of an output rotational speed of the transmission mechanism subjected to a filter processing. Updating the gear ratio of the transmission mechanism is inhibited (i) when the processed output-rotational-speed value is in a low rotational speed range with an absolute value of a rate of change of the processed output-rotational-speed value being not smaller than a given value, and also (ii) when the processed output-rotational-speed value is in the low rotational speed range with the absolute value of the rate of change of the processed output-rotational-speed value being smaller than the given value, if a certain operation that increases the absolute value is being executed.

摘要： The hybrid vehicle includes an engine, a motor connected to the engine, and an electronic control unit configured to control the motor to execute motoring to rotate a crankshaft of the engine. The electronic control unit is configured to execute speed-drop offset control when a rotation speed of the engine falls below a first rotation speed that is lower than a self-sustaining rotation speed of the engine while the engine is operated in a self-sustaining manner at the self-sustaining rotation speed.

摘要： A control apparatus for a vehicle drive-force transmitting apparatus including a gear mechanism and a continuously-variable transmission mechanism and defining first and second drive-force transmitting paths. When the continuously-variable transmission mechanism is in a failure state in which an actual gear ratio of the continuously-variable transmission mechanism is not the highest gear ratio as a target gear ratio, the control apparatus sets the target gear ratio to a transient target gear ratio that is gradually changed toward the highest gear ratio, for causing the actual gear ratio to be gradually changed toward the highest gear ratio. A rate of change of the transient target gear ratio is higher in a state in which a drive force is transmitted through the first drive-force transmitting path by the gear mechanism, than in a state in which the drive force is transmitted through the second drive-force transmitting path by the continuously-variable transmission mechanism.

摘要： A control apparatus for a drive-force transmitting apparatus that includes a transmission having primary and secondary pulleys. When a detection accuracy of rotational speed of the primary and secondary pulley is not assured, the control apparatus sets each of (i) a secondary-thrust calculation thrust ratio value used for calculation of a secondary thrust that is to be applied to the secondary pulley and (ii) a primary-thrust calculation thrust ratio value used for calculation of a primary thrust that is to be applied to the primary pulley, such that each of the secondary-thrust calculation thrust ratio value and the primary-thrust calculation thrust ratio value is dependent on a result of a determination as to whether an actual gear ratio of the transmission is the highest gear ratio and a result of a determination as to whether an input torque inputted to the transmission is lower than a given torque value.
