    摘要： A driver-initiated low traction control method limits the drive torque of a motor vehicle during operation on low traction road surfaces. The low traction control mode is initiated by actuation of a switch or by moving a transmission range selector to a Low range while the vehicle is substantially stopped, and terminated by further actuation of the switch or by returning the range selector back to the Drive setting. The low traction control mode limits the engine torque as required to limit the drive wheel torque and its rate of change, so long as cruise control is inactive, the accelerator pedal setting is less than a reference level, and the transmission is operating in a gear other than its top gear. When the low traction control mode is terminated, the engine torque limits are progressively removed in a way that does not produce perceptible acceleration or deceleration of the vehicle.

    摘要： A control apparatus and method for an automatic transmission, by which a shift is executed by simultaneously controlling release and application of different friction engaging elements, are provided which i) control a clamping force of a friction engaging element to be released and a clamping force of a friction engaging element to be applied, ii) adjust an output torque of a prime mover for driving a vehicle, iii) detect a predetermined timing that is after the start of a torque phase during a shift of the automatic transmission and before the clamping force of the friction engaging element to be applied increases to the point at which torque input to the automatic transmission can be transmitted by only the friction engaging element to be applied, and iv) output a command to gradually reduce the clamping force of the friction engaging element to be released and a command to gradually increase the clamping force of the friction engaging element to be applied, in the torque phase. A command is output to reduce the torque of the prime mover in response to detection of the predetermined timing, and a command is output to make the clamping force of the friction engaging element to be released 0 in response to detection of the predetermined timing.

    摘要： Drive elements for motor vehicles, include an internal combustion engine (1) and an automated multi-stage gearbox (9). Shifting is effected by compressed-air cylinders controlled by a control computer (45) which is programmed so as, in the event of input signals indicating vehicle speed and zero throttle, to put the currently engaged gear in the neutral position, and, in the event of an input signal indicating throttle, first to speed-control the engine to a speed which makes possible engagement of the gear, and then to give a signal to engage the gear. The engine is coupled to an electric machine (50) which is controlled by the control computer in such a manner that, in the event of the engine stopping with the freewheel function activated, the electric machine first controls the engine to a speed which makes possible engagement of a gear, and then gives a signal to engage the gear.

    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.

    摘要： A vehicular power-transmission control system comprises a continuously variable transmission CVT, which transmits the output of an engine E to wheels, a starting clutch 5, which controls the transmission of power in the continuously variable transmission, an electrical motor generator M, which can assist the engine in rotational drive, and a hydraulic pump P, which is connected to the output shaft of the engine. When the vehicle, which has come into a halt with the engine consequently stopped in an idling elimination control, is to be restarted, the power-transmission control system controls the electrical motor generator to rotate the output shaft of the engine, to which fuel supply is not allowed, thereby to drive the pump. Thereafter, when the starting clutch receiving a hydraulic pressure from the hydraulic pump starts its engagement, the power-transmission control system starts the operation of the engine.
