digital remote control
Overview
In intelligent vehicle solutions, the digital remote controller product is a critical tool for on-site development, testing, and operation personnel to debug and control vehicles. It is primarily used for real-time display of vehicle status, issuing control commands to enable vehicle control functions, real-time display of fault information, and supporting near-field diagnosis, near-field flashing, and T-BOX configuration management. Equipped with operational capabilities equivalent to automatic control systems, the digital remote controller is important in vehicle production and debugging processes.
The digital remote controller system consists of three components: the cloud, mobile client, and embedded vehicle-end. The cloud mainly manages authentication information for vehicles and mobile terminals and provides authentication services. The mobile client enables vehicle information display and control command issuance. The embedded vehicle-end integrates a remote control service unit, connects with the mobile client via a proprietary wireless communication protocol, receives control commands from the mobile client, and forwards vehicle signals collected from the vehicle to the mobile client.
For different scenarios, Jingwei Hirain’s digital remote controller can be deeply customized according to customer requirements, providing tailored product services while ensuring safety and reliability. A schematic diagram of the digital remote controller is shown below:
Product Features
- Aesthetic and Intuitive Interface Display: The UI design adopts high-contrast colors, presenting a visually appealing and unified style with a prominent theme and strong contrast, enabling intuitive display of vehicle information.
- Rich and Convenient Operation Functions: The digital remote controller is operated via the function buttons of an Android tablet device, supporting external joysticks and physical buttons for steering and driving control. This facilitates human-machine interaction and provides the same operational capabilities as automatic control systems.
- Safe and Stable Connection Method: The digital remote controller enables reliable short-range remote control, with stable vehicle connection and control maintained through heartbeat-based connectivity, ensuring safety during the vehicle control process.
- Secure and Unified Authorization Management: The cloud platform of the digital remote controller offers login authentication and authorization information management functions, ensuring information security.
- Customization and Scalability: The digital remote controller can be deeply customized according to different scenarios and customer requirements, supporting various extended functions and adaptable to multiple vehicle models and architectures.
Product Function
- Login Authentication
The digital remote controller can perform authentication between mobile devices and vehicles via the cloud platform. After successful authentication, users can log in to access interfaces for remote control, diagnostics, and other operations.
- Remote Control Mode Function
» In remote control mode, the mobile terminal connects to the vehicle via a WIFI link. The vehicle's remote control service unit processes connection requests and control commands transmitted from the mobile terminal, and forwards vehicle signals collected from the car to the mobile terminal for display.
» The remote control mode interface is divided into display and control sections. It integrates an external joystick to control vehicle steering and driving, supports emergency stop via buttons to effectively prevent accidental triggering, and provides operators with clear control feedback.
» The remote control mode features a heartbeat monitoring function: the mobile terminal and vehicle establish a heartbeat connection through Socket, with preset heartbeat intervals and access control mechanisms. In the event of heartbeat anomalies, the vehicle will decelerate to a stop to ensure control safety.
» In the UI design of the remote control mode interface, most control buttons adopt toggle or sliding touch methods, which intuitively display control results and effectively prevent accidental touches. Additionally, it supports a rainy-day mode to shield abnormal touch inputs during inclement weather.
- Near-Field Diagnostic Functions
» Obtain vehicle-wide ECU version information, including software version, hardware version, and part number details.
» Select a specific ECU for diagnosis, with capabilities to read ECU Diagnostic Trouble Codes (DTCs), clear faults, and retrieve DTC details.
» The digital remote control mobile terminal supports the storage of diagnostic records, allowing the query of diagnostic history and corresponding diagnostic details.
- Near Field Programming Function
» The near field programming mode supports ECU FOTA upgrades, ECU version information retrieval, and other functions. The digital remote controller can send programming upgrade packages to the T-BOX terminal for ECU FOTA upgrades. During programming, the progress and status information can be obtained and displayed.
» It also supports SOTA application upgrade functions, including application installation, application upgrade, application uninstallation, and application platform information retrieval.
- TBOX Configuration Management Function
» The digital remote controller can read specified T-BOX configuration information from the vehicle terminal, parse the data content, and display it.
» The digital remote controller allows editing, saving configurations, or importing external configurations, and sends the modified configurations to the vehicle terminal program for configuration.
» Supports configuration recording: read and configuration information can be stored, and recorded information can be imported or exported.
With the development of intelligent driving technology and the construction of smart ports, the debugging and other work of port autonomous driving fleets have become increasingly important. Digital remote controls have been put into use in smart ports to help address extreme and abnormal situations that autonomous driving fleets cannot handle, assist in vehicle debugging, and improve operational efficiency. In the future, the development team of Jingwei Hirain will further improve and expand this technology by introducing background interaction to create an intelligent companion for vehicles.
