Head Unit Connectivity Test Solution

Allion tackles in-car connectivity issues by integrating visual recognition, audio recognition, robotic arms, and AI testing control system.Our Head Unit Connectivity Test Solution provides the highest level of efficiency, accuracy, and flexibility.

Inquiry

Automakers have upgraded head units to create a safer and more seamless driving experience. However, connectivity or compatibility problems often frustrate users and negatively impact the driving experiences. Moreover, if these problems distract drivers, serious consequences can occur at any time.

A Revolutionary Test Solution for the Upgraded Head Unit Products

As in-vehicle infotainment features become increasingly complex, manual testing is not efficient enough to identify hidden issues. Therefore, Allion designs AI test solution to improve the overall in-vehicle wireless experience. There are four key elements in this AI solution:

1. Robotic Arm Control System

Robotic arms are used to simulate users’ behavior, such as clicking, sliding, scrolling, and other customizable user actions.

  • Clicking: Robotic arms can single- or double-click any place on a screen. For example, a robotic arm can click to pick up or hang up the phone. It can also click different buttons, such as numbers and App icons, to perform specific tasks.
  • Sliding: Robotics arms can simulate the way users finger-slide the screen.

2. Visual Recognition System

Powered by image recognition algorithms, the cameras can automatically identify objects and icons. The visual recognition system can capture fleeting error messages much faster while not being affected by human physical conditions or fatigue after a long period of time.

3. Audio Recognition System

By analyzing music waveforms, the audio recognition system can automatically identify sound cuts and distorted signals.

Figure 1 shows the original waveform of a song, while Figure 2 shows the waveform of the song being played on the head unit. In Figure 2, a distorted signal occurs at point A (0:50), and the audio is cut out for about 2-3 seconds at point B (1:50).

4. AI Testing Control System

Allion AI Testing Control System can control both Android OS and iOS devices. It can determine which stage of the test can be carried out with AI-driven automation. Besides, with big data analysis, it can optimize test schedules for vendors.

Why Do We Need AI in Head Unit Testing?

High Efficiency, High Accuracy

The accuracy of manual testing can reach somewhat 83%-90% but it is easily affected by physical conditions, visual and listening fatigue. However, automation testing can always remain 99% accuracy rate or even above.

Consistent, Accurate, and Reproducible

By integrating the four key elements, Allion AI automated test solution ensures every single test is conducted in a consistent and accurate manner. Since all test variables are precisely monitored, our AI test solution can minimize human errors and reproduce the in-car Bluetooth performance problems.

24/7 Monitoring and Testing

Working hours for human beings are 8 hours a day. However, robots can run 24 hours non-stop. An increase from 8 to 24 test hours a day suggests that the test schedule is accelerated (2-3 times faster).

Big Data Analysis

Allion AI system can analyze test results by collecting big data, such as the test items with the highest error rates and the combinations of mobile devices and head units. The results can be references for future modifications and test planning.

Get Your Head Unit Tested Wherever You Want

Allion’s Head Unit Connectivity Test Solution allows you to replicate actual driving experiences and analyze test data through robotic arms, visual and audio recognition systems, and AI test platform without asking you to send the entire vehicle or head unit to the lab.

Allion has designed 7 test items to identify connectivity issues and improve the quality of head unit products:

1. Cross-device connectivity test

A smartphone connects to the head unit for the first time.

2. Bluetooth functionality test

Make phone calls, listen to music, send and receive messages.

3. User scenario simulation

Identify and solve problems by implementing the corresponding solutions with the test array of more than 100 user scenarios.

4. Compatibility test

Generate comprehensive test conditions by taking into account of every relevant factor, such as iOS or Android OS, diverse smartphone chipsets, and different service providers.

5. Long term stability test

Test the stability performance under stress. For example, play music on the head unit for hours.

6. Bluetooth audio performance

Test the DAC (Digital to Analog Convertor) and audio electric network.

7. Bluetooth OTA performance

Test the antenna performance at different angles.
