The present invention effectively solves adverse effects such as a slow torque response and a sudden torque change caused by a turbo lag on an entire vehicle, and improves the drivability and power of the entire vehicle.

A series-hybrid vehicle includes an internal combustion engine for electric power generation and a motor generator for travelling. The internal combustion engine is cooled by a second coolant water circuit that has a main radiator. A first coolant water circuit having a sub radiator is used to cool a front wheel-side power train cooling part, a rear wheel-side power train cooling part, a water-cooled condenser, and a low temperature-side intercooler. When the vehicle is accelerating, an electrical compressor for an air conditioner comes to a stop, and the circulation of refrigerant to the water-cooled condenser is brought to a halt.

A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

A power distribution management method includes receiving accelerator pedal opening information sent by a hybrid vehicle; on the basis of the accelerator pedal opening information, respectively compiling statistics on a first opening change rate when the accelerator pedal opening is in a starting interval and when the accelerator pedal opening is increased and a second opening change rate when the accelerator pedal opening is in an overtaking interval and when the accelerator pedal opening is increased, the starting interval corresponding to a first preset range of the accelerator pedal opening, and the overtaking interval corresponding to a second preset range of the accelerator pedal opening; calculating a driver feature coefficient on the basis of the first opening change rate and the second opening change rate; and sending the driver feature coefficient to the hybrid vehicle.

Systems and methods are provided for simulating rev-matching in hybrid electric vehicles (HEVs). In particular, increased engine response is provided while downshifting during acceleration. The transmission of an HEV may include an electronic control unit that controls the speed of the engine to simulate gears, and increases the speed of the engine responsive to a driver using the gear selector to shift from one of the simulated gears to a lower one of the simulated gears, thereby providing the desired rev-matching experience. The increased engine response can be reflected in a target engine speed that is calculated based on specific gear ratios associated with each of the simulated gears.

A driving force control system for a hybrid vehicle for reducing a required time to launch the hybrid vehicle after selecting a reverse range while maintaining a driving force. The control system is configured to change an engine start threshold to restrict a startup of the engine upon satisfaction of a restricting condition, in which a low mode is established by a transmission mechanism, and a reverse drive range is selected.

Since a maximum rotation speed of a second rotary machine is set to a lower value when a supercharging pressure is high than when the supercharging pressure is low, an engine torque decreases with an rotation speed of the second rotary machine which is relatively low and the rotation speed is less likely to fall into a high-rotation state. When the supercharging pressure is relatively low and the rotation speed is less likely to reach an upper-limit rotation speed of the second rotary machine, the maximum rotation speed is set to a relatively high value. Accordingly, the engine torque does not decrease to the rotation speed which is relatively high and power performance can be easily secured. As a result, it is possible to prevent a decrease in power performance due to the decrease in the engine torque and to prevent the rotation speed from falling into a high-rotation state.
