The invention discloses a generating method and device for an engine target torque map. The method includes the steps that according to a vehicle driving index, at least one key parameter is determined; according to the at least one key parameter, at least one engine theoretic torque is acquired through calculation; according to the at least one engine theoretic torque, an initial engine target torque map is generated; the initial engine target torque map is corrected, and a theoretic engine target torque map is acquired; in combining with a preset test model, the theoretic engine target torque map is subjected to secondary correction, and the engine target torque map is acquired; and for the same one key parameter, different accelerator depths correspond to different engine theoretic torques. Due to the technical scheme, on the basis that the driving factory is fully considered, the engine target torque map is reasonably generated at the automobile developing initial stage, and therefore the driving comfort experience of a user is better met.
