Abstract
In a hybrid vehicle in which a mode change between an electric drive mode and a hybrid drive mode is carried out based on information concerning an operating condition and a driving status, an impairment of operability due to a change of the drive mode at a reverse travel of the vehicle is prevented. Upon a start of the reverse travel, the drive mode before the start of the reverse travel is continued at the start of the reverse travel.
