PROBLEM TO BE SOLVED: To provide a four-wheel drive vehicle avoiding the lack of driving force in a slope where a shift stage of a transfer device is changed over to a low speed side, and stabilizing vehicle behavior, and provide a shift method in four-wheel drive.SOLUTION: A four-wheel drive vehicle includes: a power transmission mechanism 10 having a transfer device 20 connected to an output shaft 15 of an automatic transmission 14; a changeover device 30; and a control device 40 configured to control the automatic transmission 14. The control device 40, when a shift stage of the transfer device 20 is changed over to a low speed side by the changeover device 30, prohibits automatic shift of the automatic transmission 14.SELECTED DRAWING: Figure 1
【課題】トランスファ装置の変速段を低速側にするような坂路における駆動力抜けを回避して、車両挙動を安定させる四輪駆動車両及び四輪駆動時の変速方法を提供する。【解決手段】自動変速機14の出力軸15に連結されたトランスファ装置20を有した動力伝達機構10と、切換装置30と、自動変速機14を制御する制御装置40とを備え、制御装置40を、切換装置30によりトランスファ装置20の変速段が低速側に切り換えられた場合には、自動変速機14の自動変速を禁止する構成にした。【選択図】図1
