Abstract
Disclosed are a hybrid vehicle and a method of calculating driving load therefor for determining a more effective gear shift reference in consideration of a driving mode. The method of controlling gear shift of a hybrid vehicle includes predicting required power of a forward driving path, determining a representative driving mode based on mode switch power as a reference of switch between a first driving mode using only an electric motor and a second driving mode using at least an engine and the predicted required power, and applying any one of a first gear shift map corresponding to the first driving mode based on the determined representative driving mode or a second gear shift map corresponding to the second driving mode.

A method of controlling gear shift of a hybrid vehicle, the method comprising:
- predicting, via a hybrid controller, required power of a forward driving path;
- determining a representative driving mode based on mode switch power as a reference of switch between a first driving mode using only an electric motor and a second driving mode using at least an engine and the predicted required power;
- and
- applying, via a transmission controller, any one of a first gear shift map corresponding to the first driving mode or a second gear shift map corresponding to the second driving mode based on the representative driving mode determined by the hybrid controller.
A hybrid vehicle comprising:
- a hybrid controller configured to predict required power of a forward driving path, to determine a representative driving mode based on mode switch power as a reference of switch between a first driving mode using only an electric motor and a second driving mode using at least an engine and the predicted required power, and to determine whether any one of a first gear shift map corresponding to the first driving mode or a second gear shift map corresponding to the second driving mode is applied based on the determined representative driving mode;
- and
- a transmission controller configured to apply a gear shift map determined among the first gear shift map and the second gear shift map to be applied by the hybrid controller.
