摘要： A vehicle control device calculates a target line pressure based on an instructed torque capacity of a friction engaging element and a belt capacity when the friction engaging element is determined as not engaging. Belt capacity is calculated using an input torque of a continuously variable transmission mechanism. The device calculates torque down in a driving source based on an upper limit line pressure when the calculated target line pressure exceeds such line pressure. A limit torque capacity of the friction engaging element is calculated using the input torque and a belt capacity when the friction engaging element is determined as not engaging. The belt capacity is calculated using an actual line pressure. The device restrains a slip between pulleys and a power transmitting member using the target line pressure, the torque down, and the limit torque capacity when the friction engaging element is determined as not engaging.

摘要： A gear change control device is provided in which a feedback control level for making an actual gear ratio between input rotational speed and output rotational speed of a transmission coincide with a target gear ratio is calculated. A control level calculation device calculates the feedback control level based on a deviation of acceleration of change in the actual gear ratio with respect to acceleration of change in the target gear ratio thereby making it possible to enhance the control responsiveness compared with a case in which the feedback control level is calculated based on the deviation of the actual gear ratio with respect to the target gear ratio, and also to detect the occurrence of a deviation of the actual value from the target value at early stage and carry out feedback, thus enabling gear change control to be carried out more linearly than in a conventional manner.

摘要： A control apparatus is applied to a hybrid vehicle. The hybrid vehicle includes an MG which is connected with an input shaft of a manual transmission via a first clutch that is operated by a press operation to a clutch pedal and an internal combustion engine which is connected with the MG via a second clutch. The hybrid vehicle is allowed to execute an EV traveling mode where: the internal combustion engine is stopped; the internal combustion engine and drive wheels are separated by the second clutch; and the drive wheels are driven by the MG. In the control apparatus, when the EV traveling mode is executed, a required torque is obtained based on an accelerator opening degree, and a required transmission torque is obtained based on an operation amount to the clutch pedal. And, when a smaller one of the required torque and the required transmission torque is greater than a determination value, the internal combustion engine is started.

摘要： A control system includes a drive source including an engine and a motor. A clutch is provided between the drive source and a driving wheel, wherein the clutch is engaged when a drive range is selected. The system performs, by a speed control of the motor, a control for keeping an input speed of the clutch at a target speed that is equal to the input speed at start of an engagement control of the clutch. The system judges that the clutch has started to be engaged, in response to a condition that a parameter has exceeded a predetermined threshold value when in a start region of the engagement control of the clutch, wherein the parameter changes along with a rotational fluctuation of the drive source. The system starts the judgment after awaiting satisfaction of a predetermined condition after the start of the engagement control of the clutch.
