Abstract

The invention discloses a method and device for generating an environment model of an automobile controller test. The method comprises the steps: obtaining the test type and the test device type, wherein the test type comprises an HIL test, an MIL test, and an SIL test; obtaining the test intention, wherein the test intention comprises the input and output signals of the tested controller, and the physical structure and the connection relation of the controlled object controlled by the test controller; and according to the test intention, generating the environment module interfaces corresponding to the test type and the test device and the connection relation between the environment module interfaces. The method and device are capable of improving the universality of the test environment model, and reducing the test time of the automobile controller.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a method and a device for generating an environment model of an automobile controller test. Background technique [0002] With the development of automotive electronic and electrical technology and the wide application of electronic control units, cars have become more comfortable, safe, energy-saving and environmentally friendly. However, on the one hand, the electronic and electrical systems of automobiles are becoming more and more complex, so design and testing have become crucial, and the required design cycle is longer and the cost is higher. At present, more innovations rely on electronic technology, and the realization of many functions also increasingly relies on control systems. Increased complexity makes comprehensive and efficient testing more important than ever. [0003] Testing can find and correct errors early and reduce costs, so it is indispensable no matt...
