Abstract: In a vehicle control device for controlling the vehicle, when automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in the case where a drive current value of the motor obtained when the second oil pump is driven is larger than a maximum value of the drive current value of the motor obtained when the second oil pump is driven in a normal drive state, the vehicle control device increases a minimum rotation speed of the drive source compared to a case where the drive current value of the motor is equal to or less than the maximum value, and when the automatic downshift control is executed in the case where a line pressure generated by a hydraulic pressure supplied from the first oil pump and the second oil pump is larger than a predetermined value, the vehicle control device does not increase the minimum rotation speed of the drive source even in the case where the drive current value of the motor obtained when the second oil pump is driven is larger than the maximum value.

Abstract: A vehicle is disclosed having a motor and engine selectively coupled to the motor via a clutch. The vehicle includes a controller configured to, in response to a vehicle wheel torque reversal, open the clutch to disconnect the engine from the motor, command the engine to enter a speed control mode, and control a motor output torque through a region surrounding the vehicle wheel torque reversal to reduce torque disturbances in a vehicle driveline.

Abstract: A control apparatus for a vehicle, which is provided with an engine and drive wheels, is configured, during an inertia running or stop of the vehicle, to execute a control for stopping the engine and/or disconnecting the engine from the drive wheels in each area, depending on whether a condition is satisfied or not. The condition is set based on an information transferred from other vehicle in which the control is executable during an inertia running or stop of the other vehicle. The information includes (a) a location information indicative of the each area and (b) an acceleration representative value representing a required acceleration of the other vehicle required by an operator of the other vehicle in the each area. The acceleration representative value is associated with the location information indicative of the each area.

Abstract: Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.
