摘要： A system for decelerating a hybrid vehicle, the system includes a continuously variable transmission (CVT), a brake pedal, an accelerator pedal, a sensor for detecting a vehicle deceleration, a memory for storing a target deceleration corresponding to a coasting deceleration of the vehicle, and a processor. When the brake pedal and the accelerator pedal are released, the vehicle coasts. If the vehicle deceleration does not match the target deceleration, the processor adjusts the torque output by the CVT so that the vehicle deceleration substantially matches the target deceleration.

摘要： A method of controlling a drivetrain of a vehicle in which the drivetrain comprises a motor, a transmission with starting gears and a clutch located between the motor and transmission, a manual shift lever, and a control unit, for controlling the transmission and clutch, that communicates with a speed sensor, and an accelerator pedal and shift lever actuation sensors. When starting off from coasting, a starting gear is determined in a manner that can be influenced by the driver via actuating the manual shift lever. To assist the driver, it is checked whether the transmission is in neutral and the clutch is engaged, if the vehicle speed is within a specified speed range. If so, the clutch is disengaged, another gear is engaged, and starting is initiated in combination with situation-dependent clutch engagement and carried out as a function of accelerator pedal actuation, provided the shift lever has not been actuated.

摘要： A hybrid vehicle in which a clutch is disposed between an engine and a motor/generator is controlled to suppress frequent engagement/disengagement of the clutch in a case of a coasting drive while dragging the engine. A clutch control apparatus controls the clutch and selects any one of the following drive modes: 1) an EV drive mode where the vehicle travels by only driving force of the motor/generator with the clutch disengaged; 2) an HEV drive mode where the vehicle travels by driving force of the engine and/or the motor/generator with the clutch engaged; and 3) an engine brake drive mode in which the vehicle coasts or travels by the driving force of the motor/generator while dragging the engine where the clutch is engaged, and the fuel supply is stopped when a charge of the battery is greater than or equal to a threshold value.

摘要： Vehicular drive system which is small-sized and/or improved in its fuel economy.A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.

摘要： In performing a down-shift based on a driver's intention of deceleration, an engine output increasing control is started at a time when a transfer torque capacity of the releasing clutch becomes small or zero and the actual oil pressure decreases to an initial oil pressure, not causing an acceleration feeling even upon the engine output increase. For estimating a time when which the real pressure of the releasing clutch decreases to a level of not higher than the initial pressure, the response of the real pressure relative to an oil pressure command value for the releasing clutch is approximated using a transfer characteristic of “first order lag+time delay.” An estimated real oil pressure obtained based on the transfer characteristic is compared with the initial pressure. It is determined a start timing of the engine output increasing control has been reached upon decrease of the estimated pressure to the initial pressure.
