1. Overview of the Intelligent System
1.1 Product Overview
With the growing popularity of self-driving travel, as multi-functional travel
tools, have become increasingly prevalent. However, the intelligent control
system, which serves as the core for RVs safety and intelligent control, has
failed to keep pace with market development. Currently, the entire intelligent
control system of most RVs is a patchwork of household and industrial
components, which cannot meet the requirements of driving control.
To address this issue, Intibeam Technology developed the "RVs Intelligent
Control System" in May 2023 in accordance with automotive-grade
requirements. The system integrates advanced functions and devices such as
AI human-computer interaction, voice control, automotive-grade on-board
equipment, 3D surround view and monitoring, Beidou positioning, WIFI/BT
communication, mobile phone APP expansion, and cloud data center. It
provides users with a convenient and user-friendly interactive interface,
enabling centralized control and management of various on-board devices via
touch screen, intelligent voice, mobile phone APP and other methods, and
offering users a comprehensive, intelligent control and driving assistance
solution.
The system not only achieves high integration of RV control to facilitate
mobile living, but also enhances travel safety and comfort, allowing users to
enjoy an unprecedented intelligent experience on the road. Through the
intelligent control system or mobile phone APP, you can easily control all
on-board devices, enjoy wonderful music and video, and fully appreciate the
beautiful scenery along the journey.
