The invention discloses an equivalent factor determination method and a related device, and the method comprises the steps: obtaining a target trajectory curve corresponding to the remaining capacity of a battery of a vehicle under a target working condition, and enabling the target working condition to be used for identifying a historical driving process from a starting moment to an end moment; the target residual electric quantity, corresponding to the target moment, on the target trajectory curve is used for indicating that power distribution between an engine and a battery of the vehicle is optimal at the target moment. According to the first output power of the engine, the equivalent factor and the second output power of the battery, equivalent fuel consumption of the vehicle in the historical driving process is constructed, and the target equivalent factor corresponding to the target moment is determined with the minimum equivalent fuel consumption as the optimization target. And according to the target equivalent factor corresponding to each moment, generating an equivalent factor curve corresponding to the target working condition. On the basis, the global working condition information corresponding to the historical driving process is converted into the equivalent factor, the equivalent factor curve is directly utilized subsequently, the global working condition information does not need to be traversed any more, and the calculation amount is reduced.
