To provide a controller for a hybrid vehicle capable of improving drivability when switching travel modes.SOLUTION: A controller for a hybrid vehicle has an internal combustion and a first motor capable of transmitting a driving force to first driving wheels, and a second motor capable of transmitting the driving force to second driving wheels. The first motor has a function to generate power by the driving force of the internal combustion. The controller includes: a travel mode control part which controls a travel mode; and a driving force control part controlling the driving force. The travel mode control part switches the travel mode to a first mode in which the first motor generates power by a driving force outputted by the internal combustion and a hybrid vehicle travels by the driving force of the second motor and to a second mode in which the first motor generates no power and the hybrid vehicle travels by the driving force of the second motor, and when switching to the first mode or second mode, the driving force control part increases a request driving force after lowering a request driving force than that before switching.SELECTED DRAWING: Figure 4 【課題】走行モードの切り替え時におけるドライバビリティを改善することが可能なハイブリッド車両の制御装置を提供することを課題とする。【解決手段】第１駆動輪に駆動力を伝達可能な内燃機関および第１モータと、第２駆動輪に駆動力を伝達可能な第２モータと、を有するハイブリッド車両の制御装置であって、内燃機関の駆動力により第１モータは発電する機能を有し、走行モードを制御する走行モード制御部と、駆動力を制御する駆動力制御部と、を具備し、走行モード制御部は、走行モードを、内燃機関が出力する駆動力によって第１モータが発電し、かつ第２モータの駆動力によって走行する第１モード、および第１モータは発電せず、第２モータの駆動力によって走行する第２モードに切り替え、第１モードまたは第２モードへの切り替え時に、駆動力制御部は要求駆動力を切り替え前よりも低下させた後、要求駆動力を増加させるハイブリッド車両の制御装置。【選択図】図４
