Abstract

The invention discloses a test system for ECU (Electric Control Unit) oil injection and ignition control, which comprises an FPGA (Field Programmable Gate Array) board connected with the ECU, a target machine connected with the FPGA board, and a host connected with the target machine, wherein an engine model is assembled in the target machine. The invention also discloses a test method corresponding to the test system. According to the invention, the acquisition of the oil injection and ignition signals is realized by the FPGA board, the sampling frequency is high, the signal acquisition is accurate, and the oil injection pulse width and the ignition timing can be effectively counted; meanwhile, as a driving counting module, which is used for counting the oil injection pulse width and the ignition timing, and the engine model are operated under the same target machine, the data communication is convenient and quick; and the test method can effectively reduce the development and test cost, and shortens the development period.

Description

technical field [0001] The invention belongs to the technical field of automobile control test and development, and in particular relates to a test system and a test method for ECU fuel injection ignition control. Background technique [0002] In the research of modern automotive engine management systems, increasingly complex functional requirements and strict regulatory requirements make the development process of engine ECU (Electronic Control Unit, electronic control unit) hardware and software more and more complex, so a strict and efficient development method is required To ensure the quality of product-level ECU. In order to improve the efficiency and accuracy of product development, the development of automotive electronic systems has proposed a modern model-based development process - V-mode development process, which ensures that developers can be verified in a timely manner at every step in the development process. [0003] Before the product goes on the market, ...
