    摘要: A control apparatus for an automatic transmission of twin clutch type, in which a skip downshift is executed with a light gearshift shock and in a short gearshifting time period. As illustrated in FIG. 1, after the release of a clutch C2, a command for switching over a synchro mechanism is issued at a time t3. When the r.p.m. NT of a turbine has reached the synchronous r.p.m. NT3 of the intermediate stage of the skip downshift, the oil pressure of a clutch C1 is raised in order that the rising rate of the turbine r.p.m. (speed) NT may become a predetermined value d/dt(NT1) or d/dt(NT2). Thereafter, the oil pressure of the clutch C1 is controlled in order that the turbine r.p.m. NT may maintain a value NT2 (synchronous r.p.m. of the lower speed stage of the skip downshift)+.DELTA.NT4. After the completion of the switchover of the synchro mechanism, the oil pressure of the clutch C2 is gradually raised, and that of the clutch C1 is gradually lowered. Thus, the skip downshift in a power-ON state is executed.

    摘要: A control system for improving the fuel economy of a hybrid vehicle by evaluating a fuel to be consumed for a charging operation thereby to select a running mode. Specifically, a drive control system for a hybrid vehicle including an internal combustion engine, an electric motor and a battery device. The drive control system comprises: a first evaluator for evaluating the fuel consumption in the case assuming that the run with a demanded power is made by using the electric power reserved in the battery device, while including the fuel consumption at the time when the battery device is charged with the electric power; a second evaluator for evaluating the fuel consumption in the case assuming that the run with the demanded power is made by the motive power generated by burning the fuel in the internal combustion engine; and a motive power selector for selecting one of the run using the electric motor and the run using the internal combustion engine, on the basis of the evaluation results of the first evaluator and the second evaluator.

    摘要: A drive control system for a hybrid vehicle in which an internal combustion engine is selectively coupled through a clutch mechanism to a power transmission line coupled to an electric motor. The drive control system comprises: motoring device for coupling the engine to the power transmission line to rotate the engine, with the feed of a fuel to the engine being stopped when the hybrid vehicle is driven to run by the output of the electric motor, by controlling the clutch mechanism in an applied state. Thus, it is possible to start the engine even at a low speed of the hybrid vehicle and to prevent the deterioration in the riding comfort, as might otherwise be caused by the fluctuation in a driving torque.
