PROBLEM TO BE SOLVED: To provide a hybrid vehicle and a reverse travel method therefor, which eliminate a reversing gear stage of a stepped transmission by controlling a reverse travel of a hybrid vehicle with a motor-generator controlled, thus enabling realization of a fuel economy improvement effect by reducing the weight of the vehicle.SOLUTION: A hybrid vehicle 1, in which power of an internal combustion engine 10 and that of a motor-generator 20 are transmitted to a wheel via a stepped transmission 30, includes a control device 40 for controlling a hybrid system 2, and the control device performs setting a gear stage Fgn of the stepped transmission 30 at a forward-travelling low-speed gear stage Fgi to cut off the transmission of the power of the internal combustion engine 10 to the stepped transmission 30, and reversing the motor-generator 20 to transmit the power thereof to the stepped transmission 30, when a shift lever of the stepped transmission 30 is moved to a reverse for a reverse travel, thus causing the hybrid vehicle 1 to travel in reverse. This eliminates a reverse-travelling gear stage from the stepped transmission 30.

    【課題】ハイブリッド車両の後進走行を電動発電機の制御で行うことで、有段変速機の後進用ギア段を省略して、ハイブリッド車両の軽量化による燃費向上効果を得ることができるハイブリッド車両及びその後進方走行法を提供する。【解決手段】有段変速機30を介して内燃機関10の動力と電動発電機20の動力を車輪に伝達するハイブリッド車両1において、ハイブリッドシステム2を制御する制御装置40が、後進走行時に、有段変速機30のシフトレバーが後進に操作されたときに、有段変速機30のギア段Fgnを前進走行用の低速ギア段Fgiにして、有段変速機30への内燃機関10の動力の伝達を断絶すると共に、電動発電機20を逆回転させて、電動発電機20の動力を有段変速機30へ伝達して、ハイブリッド車両1の後進走行を行う制御をするように構成されると共に、有段変速機30が後進用ギア段を備えずに構成される。【選択図】図1
