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.

摘要： A hybrid vehicle is equipped with an engine that is connected to a power split mechanism, a generator, an electric motor, and also a stepped transmission that is arranged between the electric motor and a drive shaft. An electronic control unit (an ECU) with which this hybrid vehicle is equipped revises a down line downward to make a downshift likely to occur when at least one of a prescribed generator condition and a prescribed electric motor condition is fulfilled. The generator condition includes that the temperature of the generator is equal to or higher than a first reference temperature and that an absolute value of a rotational speed of the generator decreases due to the making of the downshift. The electric motor condition includes that the temperature of the electric motor is equal to or higher than a third reference temperature.

摘要： A driving force control system for improving energy efficiency under a motor-drive mode. The control system selects the motor-drive mode from a single motor-mode where a vehicle is powered by any one of the rotary devices, and a dual motor-mode where the vehicle is powered by both rotary devices. The driving force control system is configured to select the single-motor mode rather than the dual-motor mode, provided that an increment of an energy consumption to establish the dual-motor mode is larger than a decrement of the energy consumption to be achieved by the dual-moor mode, under a driving condition where a required driving force can be achieved by either the single-motor mode or the dual-motor mode.
