Abstract:
Provided are a method and apparatus for calculating a real-time torque of an engine, and a device and a readable storage medium. The method for calculating a real-time torque of an engine comprises: looking up a corresponding first torque in an accelerator pedal map table on the basis of a vehicle speed, the opening degree of an accelerator pedal, the gear of a gearbox and the rotation speed of an engine (S10); selecting the minimum value from the first torque, a second torque and a third torque, and taking same as a fourth torque, wherein the second torque is determined on the basis of an external characteristic of the engine, and the third torque is the maximum torque corresponding to the current working condition of the engine (S20); performing torque filtering restriction on the fourth torque, so as to obtain a fifth torque (S30); determining a creeping torque (S40); obtaining a sixth torque according to the creeping torque and the fifth torque (S50); determining a seventh torque on the basis of a torque response characteristic of the engine (S60); and selecting the minimum value from the sixth torque and the seventh torque, and taking same as a real-time torque of the engine (S70). In this way, a finally obtained real-time torque of an engine is closer to the actual torque of the engine, thereby improving the accuracy of a power performance simulation result of a vehicle.
