A kind of automobile simulation method, device and automobile test simulation system

Abstract

The present invention discloses an automobile simulation method and device, and an automobile test simulation system. The method comprises: receiving a test command from a test industrial personal computer, wherein the test command includes an automobile test command or a chassis dynamometer industrial personal computer command; if the automobile test command is received, executing a simulation step, and if the chassis dynamometer industrial personal computer command is received, executing a chassis dynamometer simulation step; performing a diagnosis simulation step including simulating each electric unit of the automobile to execute the diagnosis response message returned back by the corresponding diagnosis function or simulating the control response message returned back by executing the automobile test command according to the automobile test command, and returning back corresponding message to the rest industrial personal computer or controlling the response message; and performing a drum simulation step including returning back corresponding chassis dynamometer data according to the chassis dynamometer industrial personal computer command, and returning back the chassis dynamometer data to the test industrial personal computer. Various required signals are supplied to the test system GATS for debugging so as to accelerate the debugging work of the GATS.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to an automobile simulation method, device and automobile test simulation system. Background technique [0002] All existing prototype vehicle verification, learning and testing are carried out through the trial-manufactured experimental vehicle for physical verification. The specific test method is to put the physical experimental vehicle in the drum test equipment, and then use the general assembly test system (General Assembly Test System, GATS) sends test commands to the experimental vehicle, such as diagnostic requests, control prompts, etc., by obtaining the diagnostic response returned by the experimental vehicle, the control response returned by the vehicle after the driver performs the operation according to the prompt, and the drum test collected by the industrial computer in real time The table data is used as the test result. [0003] The above-mentioned tes...
