Abstract
In mode transfer control apparatus and method for a hybrid vehicle, in a state in which the vehicle is in at least one of a start state and a travel state and in one steady-state mode of a continuously variable transmission gear ratio mode and a fixed transmission gear ratio mode, a mode transfer to the other steady-state mode of the continuously variable transmission gear ratio mode and the fixed transmission gear ratio mode is inhibited in a case where a driving point of the vehicle determined according to a detection value of a vehicle speed and a calculation value of a target driving force is present within an overlap area on a steady-state mode area map in which both of a continuously variable transmission gear ratio mode and a fixed transmission gear ratio mode are selectable.
