<p>PROBLEM TO BE SOLVED: To provide a deceleration control device for a hybrid vehicle capable of reducing loads on a motor generator and suppressing deterioration in drivability.SOLUTION: There is provided the deceleration control device applied to a hybrid vehicle 1A which includes a dual clutch-type transmission 10, and in which a first MG3 and a second MG4 are connected to a first input shaft 13 and a second input shaft 14 respectively so as to transmit power. If a deceleration is requested to the vehicle 1A and if a downshift is requested when remaining capacity of a battery 6 is a predetermined value or more, the deceleration control device estimates deceleration of the vehicle 1A to be predicted to occur when the downshift is performed while operating an engine brake. If the estimated deceleration is less than the threshold A, the deceleration control device performs such a control that the vehicle 1A is decelerated by operating the engine brake. If the estimated deceleration is equal to the threshold A or more, the deceleration control device performs such a control that an internal combustion engine 2 is rotationally driven using one motor generator while the vehicle 1A is decelerated by performing regenerative power generation using the other motor generator and the power generated by regenerative power generation is consumed.</p> |
