Testing Additional Requirements for Apple Car Key MFi

Certifying a Digital Key according to Apple’s Car Key MFi program also requires extensive testing of NFC aspects. COMPRION automates complex measurement procedures for key aspects of Apple Car Key development, helping automotive suppliers and manufacturers reduce manual effort and obtain consistent, traceable test results.

COMPRION provides a test solution for selected test cases of the Car Key program, for which tool-based testing is most beneficial, including required measurement hardware and a robot for automation. Our solution automates complex positioning and measurement processes, eliminating the error-prone need to perform hundreds of measurements manually. 

 

Test Areas

COMPRION translates the relevant Apple CarKey testing requirements into test cases, organized into three test areas. They automate complex NFC measurements and provide reproducible, traceable results. The test areas cover the performance of NFC readers, the timing behavior required for reliable device detection and communication, as well as NFC functional tests:

  • Operating Volume: Automated testing of NFC communication at defined positions, orientations, and distances.
  • Polling Timing: Measurement and evaluation of relevant NFC timing parameters for door handle readers and center consoles.

  • NFC Functional Test Cases: capture the NFC trace data, required by apple.

 

NFC Reader Compatibility Operating Volume Test Cases

Testing NFC communication across the complete operating volume of a vehicle reader requires measurements at numerous positions, orientations, and distances. Manual testing quickly becomes time-consuming and difficult to reproduce.

COMPRION automates the positioning and measurement process using the Design Validation Center software. A robot guides the Apple reference devices through precisely defined measurement points around the reader, enabling consistent and reproducible testing at more than 590 positions.

 

CL Verify A

Components

The setup required for the NFC Reader Compatibility Operating Volume Test Cases includes the following components that together enable automated and comprehensive testing according to Apple's requirements:

  • CL Verify A
    COMPRION's test hardware for validation of contactless interface design.
  • Design Validation Center
    COMPRION’s advanced software for NFC Measurement Volume design and 3D visualization of NFC-fields.
  • A set of NFC monitoring antennas.
  • Dobot Nova 2
    6-axis robot for automated and precise positioning.
  • CL Quantify (optional)
    Digital storage oscilloscope.

LPCD and Polling Timing Test Cases

LPCD and polling behavior are key parameters for NFC-based vehicle access. Verifying the relevant timing parameters traditionally requires an oscilloscope and manual evaluation of measurement results.

COMPRION integrates the required oscilloscope functionality into its test hardware based on CL Verify A. The Device Test Center software automatically performs the measurement and evaluation, eliminating the need for a separate oscilloscope and reducing manual effort.

Components

The Digital Key Test Solution for the Timing Polling Test Cases includes the following components:

  • CL Verify A
    COMPRION's test hardware for validation of contactless interface design.
  • Device Test Center
    COMPRION's advanced test case execution software for managing test plans.
  • A set of NFC monitoring antennas.

 

 

NFC Functional Testing

As part of its MFi Program, Apple mandates the use of COMPRION’s TraceCase. TraceCase is a contactless test tool for capturing and analyzing NFC communication. The included TraceCase Viewer software provides powerful visualization and analysis of recorded analog and digital signals in the lab.

Building on the CCC Digital Key Test Solution

Apple Car Key testing builds on many of the same NFC test principles and hardware already used for CCC Digital Key. COMPRION extends its established CCC Digital Key Test Solution with dedicated Apple Car Key test cases, allowing existing test environments to be leveraged for additional testing requirements.
