1. Background and Product Vision

As the integration between smart vehicles and digital terminals deepens, traditional infotainment systems face major limitations: sluggish responsiveness, restricted applications, and lack of updates. With the vision to enhance the digital driving experience, our team initiated the T11N CarPlay AI Box project. The mission was clear—develop a compact yet powerful smart device that transforms native CarPlay systems into full-featured Android environments.

Core goals included:

Seamless conversion from CarPlay to Android interface

Full 4G connectivity and wireless data transmission

Open integration with in-car digital ecosystems

2. System Architecture Design

Hardware Architecture

The T11N is powered by a high-performance automotive-grade Qualcomm octa-core processor, clocked at 2.0GHz. We engineered a multilayer PCB with integrated metal heat sinks for optimal thermal efficiency and long-term stability.

Key hardware specifications:

Qualcomm ARM Cortex-A53 8-core processor

Integrated 4G LTE Cat6 communication module

8GB LPDDR3 RAM + 128GB eMMC storage

Multi-channel wireless modules (Wi-Fi, Bluetooth 4.2, GNSS)

Software Architecture

Built on a customized Android 10 platform, the system features a proprietary UI layer and protocol adaptation core to ensure compatibility with a wide range of OEM CarPlay systems.

Key software modules include:

Multi-screen interaction protocol parser: Enables seamless main-screen and sub-screen mirroring, split-screen, and touch control.

CarPlay-to-Android bridge service: Establishes a virtual layer that communicates with the original head unit without interference.

Low-latency wireless transmission engine: Optimized for sub-100ms performance to ensure fluid media, navigation, and real-time interaction.

3. User Experience Innovation

From day one, our development was guided by real user pain points:

Limited apps in native systems

No access to third-party installations

CarPlay-Android switching required full system restarts

In response, we introduced a true “plug-and-play” model. The T11N auto-boots into Android within 5 seconds of being connected via USB—no setup required. Combined with OTA (Over-the-Air) firmware updates, users benefit from ongoing performance and feature enhancements.

4. Technical Challenges and Breakthroughs

We encountered and overcame several critical challenges during development:

Automotive power fluctuations: Developed custom voltage regulation modules supporting both 12V and 24V systems.

Multi-brand protocol compatibility: Created a CAN bus/USB protocol stack interpreter supporting over 90% of mainstream vehicle models.

Thermal and environmental reliability: Passed 72-hour burn-in tests at 85°C, ensuring rock-solid operation under extreme conditions.

5. Looking Ahead

T11N is a flagship product in our in-car smart device lineup, representing not just technical innovation but a bold step toward open, intelligent vehicle ecosystems. Future iterations will integrate AI voice assistants, smart home device connectivity, and edge computing for next-level "vehicle-cloud-human" interaction.

The T11N CarPlay-to-Android AI Box is a testament to our relentless pursuit of intelligent driving solutions. By transforming closed systems into dynamic platforms, we are redefining what’s possible inside the car. As we move forward, we remain committed to our vision: Technology that empowers freedom on the road.
