Mode transition control device and mode transition control method for hybrid vehicle

摘要

PPROBLEM TO BE SOLVED: To provide a mode transition controller and a mode transition control method of a hybrid car, with which mode transition from electric vehicle running mode to hybrid car running mode can be performed without delay, from optimum timing. PSOLUTION: An integral controller 6 starts mode transition, when the sum of engine input rotational speed i and the value obtained by multiplying engine input rotational acceleration (di/dt) by gain (K) exceeds the driving force request threshold A which has been set previously at the electric vehicle run mode.
