  • System and method for enhanced emulation of connected vehicle applications
    Patent number: 10303817
    Abstract: An emulator for a test scenario corresponding to a connected vehicle application is presented. The emulator includes a test bed for testing a device under test (DUT) communicatively coupled to emulated intelligent transportation system (ITS) stations. The test bed also includes a processor configured to emulate the test scenario based on user-defined configuration parameters that define a behavior of the DUT and each of the emulated ITS stations during simulated events in the test scenario. The processor further includes a mobility engine configured to generate and periodically update one or more mobility parameters corresponding to the DUT and the emulated ITS stations based on the corresponding configuration parameters. The test bed further includes a channel emulator, a controller area network (CAN) simulator, and a global navigational satellite system (GNSS) simulator integrated into a single test bed for holistically emulating the test scenario and validating a desired functionality of the DUT.
