HMI infortainment Sub System

Overview The HMI infotainment subsystem is designed to provide real-time vehicle telemetry and controls through an intuitive graphical interface. The system is based on the iWave RZ/G2L SMARC Development Kit and features a 10.1-inch display running a Linux-based operating system. The HMI serves as the primary interface between the user and the vehicle’s motor control ECU Unit, which is connected via Ethernet.

Components

1. Rz/g2l Applications processors
2. Linux OS
3. 10Inch touch LCD
4. LVGL graphics software

Boot Process

1. Splash Screen – On startup, the system displays a splash screen.
2. Dashboard Interface – After booting, the user is presented with the main dashboard.

Dashboard Components

The dashboard provides essential real-time vehicle data and controls, including:

• Speedometer – Displays current vehicle speed.
• Battery Gauge – Indicates the battery charge level.
• Accelerator & Brake Controls – Virtual controls for acceleration and braking.
• Regenerative Braking Bar – Shows the level of energy being recovered through braking.
• Motor Temperature Bar – Displays the current temperature of the motor.
• Fault Detection Indicator – Alerts the user to system faults or errors.
• Start/Stop Button – Used to power the vehicle system on or off.
• Menu Option – Opens an interactive settings window.
