本发明的混合动力车辆的控制方法是具有:发动机与驱动轴连接且包含构成为与发动机连动旋转的发电机的发电系统、与发电系统连接且接收来自构成为能够充电的蓄电池的电力供给而进行驱动的驱动系统的混合动力车辆的控制方法。在该控制方法中,根据驱动系统的状态,求出对发电系统的转数指令值,以使发电系统的转数成为转数指令值的方式,求出对发电系统的扭矩指令值,对扭矩指令值进行抑制在发动机与发电机的连接部产生的固有振动成分的减振控制,计算对发电系统的最终扭矩指令值,在可能发生因与固有振动成分不同的成分的振动引起的系统共振的情况下,不进行减振控制,而将扭矩指令值作为最终扭矩指令值。
A method for controlling a hybrid vehicle is a method for controlling a hybrid vehicle having a power generation system in which an engine and a drive shaft are connected and which includes a power generator configured to rotate together with the engine, and a drive system that is connected to the power generation system and driven by receiving electric power supplied from a chargeable battery. In this control method, a rotational speed command value for the power generation system is derived in accordance with a state of the drive system, a torque command value for the power generation system is derived such that the rotational speed of the power generation system reaches the rotational speed command value, damping control to suppress a natural vibration component generated in a part via which the engine and power generator are connected is performed on the torque command value to calculate a final torque command value for the power generation system, and when system resonance could occur as a result of vibration of a component different from the natural vibration component, the torque command value is established as the final torque command value without performing the damping control.
