How to Choose the Suitable Smart Dashboard for the Electrification Conversion of Wuling Journey MPV? (10.1-inch Touchscreen with CAN Support)
As the Wuling Journey MPV transitions from internal combustion to full electrification, one of the most impactful upgrades is the integration of a smart dashboard—a modern, digital interface that enhances driver experience, monitors vehicle performance, and centralizes control. A 10.1-inch touchscreen with CAN (Controller Area Network) support is ideal for this conversion, offering both aesthetic appeal and functional integration. However, selecting the right unit requires careful consideration of compatibility, functionality, and reliability.
- CAN Bus Integration is Crucial
The heart of any electric vehicle (EV) conversion lies in communication between components. The 120kW 3-in-1 powertrain provided uses a CAN-based communication protocol to relay data from the motor, controller, and sensors (e.g., PT1000 temperature sensor, resolver speed sensor). Your smart dashboard must support CAN bus input to read real-time data such as motor speed (up to 15,000 rpm), torque output (peak 240 Nm), battery voltage (385V platform), and system efficiency (≥92%). Without CAN support, the dashboard becomes a decorative screen rather than a diagnostic and control hub.
Ensure the dashboard can parse standard CAN messages (e.g., CAN 2.0A/B) and, ideally, supports custom DBC (CAN database) file loading so you can map signals from your specific motor controller (e.g., TZ200XS120-385 model). This allows accurate display of parameters like power (kW), current (A), and fault codes.
- Screen Size and Mounting Compatibility
A 10.1-inch touchscreen offers an optimal balance between visibility and fitment in the Wuling Journey’s dashboard cavity. Confirm the physical dimensions and mounting depth match the original dashboard space. Look for units with flush or bezel-mounted designs that integrate seamlessly without obstructing air vents or controls. IP67-rated enclosures are preferable, matching the powertrain’s protection level for dust and moisture resistance.
- Processing Power and Operating System
Choose a dashboard with sufficient processing power (e.g., quad-core ARM processor) and at least 2GB RAM to ensure smooth operation. It should run a flexible OS—such as Android 10+ or a real-time OS (RTOS)—to support app integration (e.g., navigation, media, vehicle diagnostics). Android-based systems allow installation of EV-specific apps like Torque Pro or custom CAN readers via OBD2-CAN adapters.
- Display Quality and Visibility
Opt for an IPS LCD or OLED screen with high brightness (≥800 nits) for daylight visibility. Touch responsiveness should be excellent, even with gloves. Anti-reflective coating and wide viewing angles ensure readability from different seating positions.
- Connectivity and Expandability
The ideal smart dashboard should offer:
- OBD2/CAN interface(built-in or via adapter)
- Bluetooth and Wi-Fifor phone mirroring and updates
- GPS modulefor speed and navigation
- Multiple USB portsfor peripherals
- Support for reverse camera and ADAS inputs, if desired
This ensures the dashboard evolves with future upgrades.
- Customization and User Interface
Look for dashboards that allow customizable dash layouts—e.g., displaying motor RPM instead of engine RPM, battery SOC (State of Charge), regenerative braking levels, and temperature readings from the liquid-cooled system. Some advanced units support programmable warning alerts (e.g., over-temperature, high current) based on CAN data.
- Power Supply and Voltage Compatibility
The dashboard must operate reliably on 12V DC, derived from the vehicle’s low-voltage system (powered by a DC-DC converter). Ensure it supports wide input voltage (9–16V) to handle voltage fluctuations during regenerative braking or cold starts. Low-power standby modes help preserve the 12V battery when the vehicle is off.
- Reliability and Build Quality
Given the MPV’s design life of 20 years or 300,000 km, the dashboard should use automotive-grade components built to withstand vibration, temperature extremes (-30°C to +85°C), and electromagnetic interference. Avoid consumer-grade tablets not designed for automotive use.
- Software Updates and Support
Choose a brand that provides regular firmware updates, technical documentation, and developer support. Open-source platforms or those with SDKs allow deeper customization by EV conversion enthusiasts.
- Safety and Legal Compliance
Ensure the dashboard complies with automotive safety standards (e.g., E-Mark, ISO 14508) and does not distract the driver. Avoid overly complex interfaces or excessive animations while driving.
Conclusion
A 10.1-inch smart touchscreen with CAN support is not just an upgrade—it’s a necessity for a professional, safe, and informative electrification conversion of the Wuling Journey MPV. When selected wisely, it transforms the driving experience, offering real-time insights into the high-performance 120kW PMSM powertrain, enhancing usability, and giving the vehicle a truly modern EV feel. Prioritize CAN integration, reliability, and customization to ensure your smart dashboard becomes the intelligent core of your electric MPV.
