    Abstract: To provide an engine power-train control apparatus and method for securing both operability and safety by controlling an actual acceleration/deceleration to a target acceleration/deceleration requested by a driver under an undangerous traveling condition and changing the target acceleration/deceleration so as to take precedence of safety traveling if the driver encounters a dangerous traveling condition. To achieve the above mentioned: the control is performed in which acceleration/deceleration and speed of a motor vehicle are detected; a target acceleration/deceleration is operated; a road condition such as a road gradient or presence or absence of a forward motor vehicle is detected to decide whether the road condition is dangerous; and the target acceleration is changed if the condition is decided to be dangerous.

    Abstract: A control apparatus and a control method for an automatic transmission, improved over those devised to minimize torque fluctuations which, if left unchecked, give vehicle passengers a disagreeable feeling upon a gear shift. The inventive control apparatus and method, aimed at suppressing such torque fluctuations during a shift of the transmission thereby to improve robustness and provide good shift characteristics, involve recognizing an inertia phase in which the engine speed starts to drop during the shift. At the beginning of the inertia phase, hydraulic pressures supplied to frictional engaging devices in the transmission are kept constant to suppress the torque fluctuations.

    Abstract: A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.
