    摘要: A hybrid vehicle comprises an engine 2, a motor generator 4, a torque converter 6 with a lock-up clutch 5, and a ratio-change mechanism 7. A control system for the hybrid vehicle comprises a rotational sensor 22, which detects the slip ratio of the torque converter, and a hydraulic control valve 12, which controls the engagement of the lock-up clutch. While the vehicle is moving along with the accelerator pedal being released from its stepped down condition, a driving force from the wheels is transmitted to the motor generator 4 for energy regeneration. If the slip ratio of the torque converter is equal to or smaller than a first threshold value, then only the lock-up clutch is controlled into engagement. However, if the slip ratio is between the first threshold value and a second threshold value, then additionally the motor generator is controlled in cooperative operation.

    摘要: An in-gear oil pressure correcting section corrects engagement control oil pressure set up by an oil pressure supply control section over the entire range to be reduced by first predetermined pressure. An engagement determining section determines, on the basis of a torque converter slip ratio calculated by a calculating section, whether a frictional engagement element of a destination gear starts to engage or not. An addition correcting control section corrects the corrected engagement control oil pressure to add second predetermined pressure thereto in the case where engagement of the frictional engagement element has not been started yet when a timer measures first predetermined time. The addition correcting control section further corrects the corrected engagement control oil pressure to add third predetermined pressure thereto in the case where the engagement of the frictional engagement element has not been started yet when the timer measures second predetermined time.

    摘要: A control device for a hybrid vehicle prevents a decrease in the total amount of regenerated energy in the entire vehicle while ensuring the stability of the vehicle when the vehicle decelerates. When the vehicle decelerates and regenerated energy is recovered by the regeneration operation of front motor and rear motor, the ECU sets the amount of regeneration, which is transferred from front wheels to rear wheels, depending on the steered angle of the front wheels and on the deceleration state of the vehicle. In addition, the ECU subtracts the amount of regeneration to be transferred from regeneration torque command value for rear wheels demanding from the rear motor, and adds the same amount of regeneration to regeneration torque command value for front wheels demanding from the front motor.

    摘要: A control device for a vehicle controls a motor-driven pump at an appropriate timing when an internal combustion engine is stopped or starts. An ECU of the control device comprises an operation determination section which determines whether or not the motor-driven pump is operated depending on the value of an idling stop flag that makes the internal combustion engine stop, depending on a measured value output from an oil pressure sensor for measuring oil pressure in oil lines providing operation oil to a torque converter and a transmission, and depending on a measured value output from an oil temperature sensor for measuring the temperature of the operation oil; and a target electrical current calculation section for calculating a target value of electrical current to be supplied during the operation of the motor-driven oil pump depending on the determination result by the operation determination section. The target electrical current calculated by the target electrical current calculation section is input to a driving section of the motor-driven oil pump, and the driving section provides driving electrical power to the pump depending on the target electrical current.
