    摘要: A control system includes an engine speed control module, a fuel control module, and an air control module. The engine speed control module controls an actual speed of an engine based a desired power to be generated by combustion in the engine, wherein the desired power is a product of a desired speed of the engine and a desired torque output of the engine. When operating in a fuel lead mode, the fuel control module controls fuel flow in the engine by adjusting a desired fuel mass for each activated cylinder of the engine based on the desired power. The air control module controls air flow in the engine based on an actual air/fuel ratio of the engine resulting from the desired fuel mass.

    摘要: A method for the operation of a drivetrain comprising an automatic transmission, a motor and at least five shift elements in which two shift elements are engaged and three shift elements are disengaged. When carrying out an upshift or downshift, a first shift element is either disengaged or engaged, and a second shift element is engaged or disengaged. While the first upshift or downshift is being carried out, a second shift element is prepared for disengaging or engaging and a third shift element is prepared for engaging or disengaging. Actuation of the second shift element occurs by virtue of a minimum selection of a first alternative or a maximum selection a second alternative. While the first upshift or downshift is being carried out and while the second upshift or downshift is being carried out, at least one fourth shift element is kept engaged or nearly engaged.

    摘要: A shift control apparatus for an automatic transmission having an automatic shift mode for performing a shift operation by determining a gear position or gear ratio to be set according to a vehicle running condition and a manual shift mode for performing a shift operation instructed by a manual operation by an operator. The shift control apparatus includes a region determining unit for determining whether the present running condition is in a first region where downshift is performed at the present gear position or gear ratio in the automatic shift mode or in a second region higher in vehicle speed than the first region, and an upshift allowing unit for allowing upshift instructed by the manual operation by the operator in the manual shift mode when the region determining unit has determined that the present running condition is in the second region.

    摘要: A clutch control apparatus for a vehicle provided with a hydraulic clutch in the middle of a power transmission path between an engine and a drive wheel. Before the clutch of the vehicle is brought into an engagement state, intermittent hydraulic pressure Y is applied to the clutch while maintaining the clutch in a disengagement state, and thereafter a predetermined hydraulic pressure is applied to the clutch to bring it into the engagement state. A solenoid valve is provided to control hydraulic pressure supplied to the clutch. Before the clutch is brought into the engagement state, a pulsed drive current D is supplied to the solenoid valve. The clutch control apparatus so configured suppresses a motion delay at the time of engaging the clutch, thereby allowing a quick and smooth start and shifting of the clutch.

    摘要: In response to a start-engagement operation command, the control procedure of the invention starts increasing a hydraulic pressure applied to a clutch when a reference time Tc0 decreases to or below a required hydraulic pressure change time Tc1. Here the reference time Tc0 is calculated from a previously learnt time correction value Tc2 and a rotation speed difference between a rotation speed Nin of an input shaft and a rotation speed Ne of an engine (steps S150 to S190). The control procedure learns and updates the time correction value Tc2 according to a variation in acceleration of a vehicle possibly arising in the course of engagement of the clutch (steps S210 to S300). Such learning of the time correction value Tc2 effectively corrects the engagement timing of the clutch, which may be varied by ageing or another cause, to an adequate level. The control procedure of the invention effectively reduces the potential shocks due to a variation in acceleration of the vehicle possibly arising in the course of engagement of the clutch.
