Selecting or upgrading the dashboard system for Wuling electric pickup trucks is essential for achieving optimal vehicle monitoring, enhancing the driving experience, and ensuring system integration. For compact, modern applications, a 1.81-inch circular smart small dashboard with CAN bus communication provides a stylish, feature-rich, and intelligent interactive interface. This guide outlines key considerations for choosing the most suitable dashboard solution, aligning with Wuling pickup's technical and operational requirements (particularly models equipped with advanced electric drive systems).

1. Size & Form Factor: Compact Space-Saving Design

The 1.81-inch circular display is ideal for vehicles with limited cockpit space. Its small footprint allows integration into minimalist center panels without obstructing the driver's view or interfering with controls. Ensure the dashboard housing design facilitates easy installation and fits standard dashboard cutouts. Compact size should not compromise readability—choose a high-brightness display to ensure clear visibility even in direct sunlight.

2. Display Technology & Readability

Despite its small size, the display must present clear, sharp information. Choose products using OLED or high-resolution TFT LCD technology for high contrast, fast refresh rates, and wide viewing angles. Critical data—such as speed, battery level, power output, and fault warnings—must be immediately legible. Customizable display layouts or screen modes (e.g., economy, power, range modes) add practical value for fleet or commercial users.

3. Smart Features & Connectivity

A "smart" dashboard should go beyond basic readings. Look for models equipped with an integrated microprocessor to support real-time data processing, trip logging, battery state-of-charge estimation, and driving behavior analysis. Bluetooth or Wi-Fi connectivity enables pairing with smartphones for notifications, navigation, or wireless updates, enhancing convenience while maintaining a clean interface.

4. CAN Bus Integration for Seamless Communication

The dashboard must support CAN communication protocols to interact with the vehicle's core systems. The vehicle's motor control, battery management, and diagnostics all rely on the CAN network. Your dashboard should be able to decode standard CAN messages from the motor controller and BMS. Verify compatibility with the vehicle's CAN communication identifiers to ensure accurate display of key information such as motor speed, wheel torque, and system efficiency.

5. Compatibility with Vehicle Parameters

Even with its small size, the dashboard should accurately reflect vehicle performance. Ensure it can display:

• Vehicle speed and drive system RPM
• Torque and power output
• Battery voltage range
• Readings from temperature sensors
• Fault codes from motor or controller

This level of integration facilitates preventive maintenance and safe operation.

6. Environmental Durability & Reliability

Commercial pickups face extreme conditions. The dashboard must meet high protection ratings to resist dust and water splash—critical for vehicles operating in rain, muddy roads, or during washing. It should also withstand wide operating temperature ranges and mechanical vibration from rough terrain. High-quality insulating materials for internal circuits ensure long-term reliability under thermal stress.

7. Power Supply & Energy Efficiency

The dashboard is typically powered by the vehicle's 12V low-voltage auxiliary system. Ensure it operates efficiently within a 9-16V DC voltage fluctuation range. Low-power design helps extend auxiliary battery life during vehicle idle periods or energy recovery.

8. Scalability & Future Adaptability

Choose a dashboard with firmware upgrade capability and an open CAN architecture. This allows future integration with telematics, GPS tracking, or fleet management systems. Some smart dashboards support modular expansion to add sensors or connect to advanced driver assistance system features.

Summary

For Wuling pickups, a 1.81-inch circular smart small dashboard with CAN integration is more than just a display—it's a critical interface between driver and vehicle. Prioritize compact design, high readability, stable CAN communication, environmental adaptability, and smart features. By aligning with vehicle performance standards—such as high-speed data monitoring, thermal management, and long design life—you'll ensure a modern, reliable, and intelligent dashboard solution that comprehensively enhances safety, efficiency, and user experience. Whether for fleet operations or personal use, the right dashboard transforms data into actionable insights—small in size, powerful in function.
