The invention provides a method and a device for calculating the endurance of an extended-range automobile. The method comprises the following steps: acquiring the residual electric quantity percentage and the residual oil quantity of an oil tank of the extended-range automobile at the current moment, and determining the battery pack capacity, the average power consumption and the oil-electricity conversion ratio of the extended-range automobile; based on the remaining capacity percentage, the battery pack capacity and the average power consumption, determining the power endurance of the extended-range automobile; determining the oil endurance of the extended-range automobile based on the remaining oil quantity of the oil tank, the oil-electricity conversion ratio and the average power consumption; acquiring state information of the extended-range automobile, and determining a target scene where the extended-range automobile is located at the current moment by using a scene recognition strategy based on the state information; according to the target scene, correcting a power endurance adjustment coefficient and/or an oil endurance adjustment coefficient by using an endurance value updating strategy; and updating the power endurance and the oil endurance according to the corrected power endurance adjustment coefficient and/or oil endurance adjustment coefficient. By means of the technical means, the problem that in the prior art, the endurance of an extended-range automobile abnormally jumps is solved.
