Abstract
A computer includes a processor and a memory, the memory including instructions executable by the processor to identify a diagnostic test to perform for a vehicle component, identify one of a plurality of XiL platforms on which to perform the diagnostic test, and perform the diagnostic test on the identified XiL platforms.
Claims18
A system, comprising a computer including a processor and a memory, the memory including instructions executable by the processor to:
- simulate a vehicle and an environment in which operation of the vehicle is simulated;
- identify a diagnostic test to perform for a specified vehicle component of the vehicle operating in the simulated environment, the diagnostic test including a control strategy or a regulation strategy of the specified vehicle component and executable on each of a plurality of X-in-the-loop (XiL) platforms, the plurality of XiL platforms including a software-in-the-loop (SiL) platform, a hardware-in-the-loop (HiL) platform, a model-in-the-loop (MiL) platform, and a driver-in-the-loop (DiL) platform;
- identify one of the plurality of XiL platforms on which to perform the diagnostic test;
- select from a plurality of software agents separate from the XiL platforms for communicating with the identified XiL platform based on the identified XiL platform, wherein a software agent for the SiL platform and the HiL platform is shared;
- and
- perform the diagnostic test for the specified vehicle component on the identified XiL platform.

A method, comprising:
- simulating a vehicle and an environment in which operation of the vehicle is simulated;
- identifying a diagnostic test to perform for a specified vehicle component of the vehicle operating in the simulated environment, the diagnostic test including a control strategy or a regulation strategy of the specified vehicle component and executable on each of a plurality of X-in-the-loop (XiL) platforms, the plurality of XiL platforms including a software-in-the-loop (SiL) platform, a hardware-in-the-loop (HiL) platform, a model-in-the-loop (MiL) platform, and a driver-in-the-loop (DiL) platform;
- identifying one of the plurality of XiL platforms on which to perform the diagnostic test;
- selecting from a plurality of software agents separate from the XiL platforms for communicating with the identified XiL platform based on the identified XiL platform, wherein a software agent for the SiL platform and the HiL platform is shared;
- and
- performing the diagnostic test for the specified vehicle component on the identified XiL platform.
