  • An object of the present invention is to provide a hybrid vehicle that can improve the riding comfort and fuel consumption of the vehicle during rapid acceleration, and a control method therefor.
  • the hybrid vehicle of the present invention that achieves the above object includes a hybrid system using at least one of a motor generator and an engine connected to a battery as a drive source, an automatic transmission coupled to the engine, the hybrid system, and an automatic system.
  • the control means calculates a required torque of the hybrid vehicle when a kickdown operation of the automatic transmission is requested, and the requested torque and the engine If the torque difference from the torque of the motor generator is less than the maximum torque of the motor generator, the motor generator is driven to rotate and assist the travel of the hybrid vehicle without performing the kick down operation. It is a feature.
  • a hybrid vehicle control method of the present invention that achieves the above object includes: a hybrid system using at least one of a motor generator and an engine connected to a battery as a drive source; and an automatic transmission coupled to the engine.

If the torque difference is less than the maximum torque of the motor generator compared to the maximum torque of the generator, the hybrid generator is driven to rotate without driving the kickdown operation. It is characterized by assisting.
  • the actual kickdown operation becomes unnecessary by assisting the traveling of the hybrid vehicle by the motor generator. Since it did in this way, the riding comfort and fuel consumption of the vehicle at the time of rapid acceleration can be improved.
