The invention discloses a range extender and a control method and device for the range extender, and the method comprises the steps: obtaining the remaining electric quantity of a battery of a vehicle and the traction demand power, determining the range extending power output by the range extender when the remaining electric quantity of the battery cannot completely meet the traction demand power, and determining the range extending power output by the range extender when the range extending power is greater than a set power threshold value; it is indicated that the range extender needs to output large range extending power to meet the traction demand power, and the engine output torque of the range extender is controlled to correspondingly change along with the range extending power. According to the method, the adverse effect of the range extender on the vehicle sound vibration roughness caused by noise brought by too high rotating speed when the range extending power is increased by increasing the rotating speed of the engine in a conventional mode is reduced, the engine output torque is controlled to correspondingly change along with the range extending power, and the range extending power can meet the output requirement while the range extending power meets the output requirement. And the influence of the noise of the range extender on the vehicle sound vibration roughness is reduced.
本发明公开了一种增程器、增程器的控制方法和装置，通过获取车辆的电池剩余电量和牵引需求功率，在电池剩余电量无法完全满足牵引需求功率时，确定出增程器输出的增程功率，在增程功率大于设定的功率阈值时，说明需要增程器输出较大的增程功率满足牵引需求功率，控制增程器的发动机输出扭矩跟随增程功率对应变化。该方法减少了常规方式中通过提高发动机转速增大增程功率时，由于过高转速带来的噪音导致增程器对车辆声振粗糙度的不利影响，控制发动机输出扭矩跟随增程功率对应变化，可以保障增程功率达到输出要求的同时，降低增程器噪音对车辆声振粗糙度的影响。
