With the rapid expansion of the new energy mobility industry, electric tricycles are undergoing accelerated upgrades toward intelligence and digitalization. As vital transport vehicles for short-distance haulage, logistics delivery, and urban-rural travel, they are subject to rising user demands for vehicle safety, driving experience, and information interaction performance. Features including color-screen instrument clusters, rearview cameras, and smart human-machine interaction are gradually becoming standard equipment for mid-to-high-end tricycle models.
Currently, rearview camera solutions deployed on low-speed vehicles such as electric tricycles and senior mobility scooters suffer from multiple drawbacks: poor compatibility with multi-camera protocols, susceptible video signal interference, high overall system costs, and lengthy development cycles. To address these pain points, MEGAHUNT has launched a reference solution integrating color-screen instrument cluster and rearview camera for tricycles, enabling customers to rapidly develop next-generation intelligent terminals featuring high-definition display, safety assistance, and smart interaction capabilities.
Reference Solution: Tricycle Color Instrument Cluster with Rearview Camera
MEGAHUNT’s tricycle color-screen instrument cluster & rearview camera reference solution adopts the MH2435 as its main control chip. Built on the FreeRTOS + LVGL GUI development framework, the solution delivers full functionalities including dashboard data display, input/output control, and real-time rearview video rendering.
It establishes data interconnection with the vehicle control unit via single-wire communication or CAN bus to support real-time exchange of vehicle operating data. The platform also supports expansion of millimeter-wave radar modules to realize Rear Collision Warning (RCW), delivering comprehensive safeguards for driving safety. Furthermore, Bluetooth mobile phone connectivity is integrated to enable smart functions such as keyless passive unlocking and audio playback.
- Full HD Display with Greatly Improved HMI Experience
Supports RGB565 and RGB888 display interfaces to deliver richer, finer visual effects, enabling clearer rendering of dashboard data and rearview footage.
- Single Power Supply Design to Cut System Costs
Adopts a single-power supply architecture that effectively reduces the number of peripheral components, lowers BOM cost, while enhancing system stability and mass-production reliability.
