To provide a controller of a hybrid vehicle which can start an engine without giving a sense of incongruity to a driver.
In the hybrid vehicle, an engine 2, a first motor 3, a second motor 4 and an output shaft 6 which serves as coupling relation by a planetary gear unit. The controller 1 of the hybrid vehicle includes an engine control means 20 capable of controlling to drive the engine 2, and a motor control means 24 capable of controlling to drive the first motor 3 and the second motor 4. The motor control means 24 controls to drive the first motor 3 and the second motor 4 within a motor limiting torque retaining an excess force for smoothly starting the engine 2 by the first motor 3 and the second motor 4 during traveling during controlling to stop the engine 2 by the engine control means 20. Thus, when the engine 2 is started, the engine 2 can be smoothly started, and prevents a driver from being given by a sense of incongruity.
