Abstract:
A method of controlling a hybrid vehicle for reducing path loss of energy when recovered energy at the time of gear shifting is transmitted to a hybrid start generator includes steps of determining a currently required torque and a predicted acceleration at a near-future time, determining a predicted speed at the near-future time based on a current speed and the predicted acceleration, determining when it is determined that one of engine start and shift conditions is satisfied at a current time based on at least one of the required torque and the current speed, whether the remaining one of the engine start shift conditions is satisfied at the near-future time, and controlling an event corresponding to the satisfied condition at the current time is delayed or an event corresponding to the satisfied condition at the near-future time is advanced when the remaining one condition is satisfied.
