摘要： Transmission torque of a shift progress side engagement device is set based on engine power, shift progressing power, and battery power such that MG1 torque and MG2 torque are limited due to the limitation of the battery power when shifting a stepped transmission is suppressed. The stepped transmission is shifted with the transmission torque which takes into account the input-output balance of the respective powers.

摘要： Based on a determination result by a nitrogen concentration determination section, an electronic control unit changes a switching line used to switch between a differential state and a non-differential state of a differential mechanism and a gear shift line used to switch a gear stage of an automatic transmission mechanism. In conjunction with a change of an engine operation point to a high-speed side in a nitrogen-enriched state of intake air, a first motor rotational speed in the differential state of the differential mechanism becomes higher than that in a non-enriched state of the intake air. Thus, corresponding to the above, the differential mechanism is appropriately switched between the differential state and the non-differential state, and the gear stage of the automatic transmission mechanism is appropriately switched.

摘要： A vehicle control apparatus selects one of a power-on control and a power-off control for execution of a shift-down action in a transmission of a vehicle, and implements the selected power-on or power-off control. When a running speed of the vehicle is not lower than a predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on a target input torque that is to be inputted to the transmission. When the vehicle running speed is lower than the predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on an actual input torque that is actually inputted to the transmission.

摘要： A control device is provided for a vehicle which includes an electric motor that executes regeneration during deceleration of the vehicle and which performs manned running with at least one occupant in the vehicle and also unmanned running without any occupant in the vehicle. The control device is configured to cause the electric motor to execute the regeneration within a regeneration allowable range, such that the regeneration allowable range for the unmanned running of the vehicle is larger than the regeneration allowable range for the manned running of the vehicle. The regeneration allowable range is defined by, for example, an allowable maximum regenerative torque that is variable depending on a running speed of the vehicle upon the regeneration by the electric motor.
