Ethernet Bootloader and Diagnostic services based on DoIP

In this demo, the Ethernet-based bootloader using UDS over DoIP showcases a fast and reliable method for updating ECU firmware through Ethernet. It uses the UDS protocol for diagnostics and reprogramming, while DoIP provides high-speed and stable data transfer. It ensures security through authentication and integrity checks, allowing only trusted software to be deployed to the ECU. This reduces downtime, speeds up development and maintenance, and ensures compliance with automotive safety and security standards. With its efficiency, reliability, and robust design, the bootloader is well-suited for modern vehicles and next-generation vehicle architectures.

SOMEIP Protocol

Service-Oriented MiddlewarE over IP (SOME/IP) is a protocol designed for service-oriented communication in automotive and embedded systems. It facilitates inter-process and inter-device communication over IP-based networks, supporting both message-based and event-driven architectures. The protocol provides a standardized, efficient, and scalable communication framework for service-oriented architectures enabling seamless interaction between distributed software components across different electronic control units (ECUs) within a vehicle, supporting the complex and dynamic communication requirements of modern automotive applications.

Ethernet Bootloader for high‑performance ECU

The Ethernet Bootloader is built for high-performance ECUs, enabling fast and reliable firmware flashing over Ethernet using the UDS protocol. Designed for production readiness, it supports secure update flows with authentication and data integrity checks, ensuring that only verified software is deployed to the ECU. This solution minimizes downtime, improves efficiency in development and field updates, and meets automotive safety and security standards, making it ideal for next-generation vehicle architectures.

E-Mobility: Motor Inverter Driver Demonstrator

This demo showcases a 48V–60V, 10kW BLDC motor inverter designed on Infineon AURIX TC with a block commutation algorithm. Using Hall sensor feedback and a variable potentiometer, the system achieves smooth operation, precise speed control, and quick responsiveness—demonstrating reliable and versatile motor control.

ADAS Demo Object Detection

This demo showcases a camera-based object detection system, built on Nvidia Jetson Nano with YOLO deep learning. Mounted on a vehicle, the system processes live camera input in real time to detect vehicles, pedestrians, and objects, displaying results at 25 FPS with bounding boxes. This demonstrates the perception phase of ADAS technology, where the system identifies surroundings for safer driving. Such systems form the foundation for advanced safety features in modern vehicles.

Anti-Pinch Mechanism for Power Windows

In this demo, the Crevavi team showcases a prototyped anti-pinch mechanism for power windows, a key safety feature in vehicles. The system detects obstacles in the window path by monitoring motor current and reverses the window direction to prevent damage or injury. Built with an automotive-grade microcontroller, motor driver, current sensor, and regulator kit, it ensures reliable safety. Future enhancements include automatic window closure when the ignition is turned off.

Automatic Rain Sensing Windshield Wiper

In this demo, the Crevavi team presents an automatic rain-sensing windshield wiper system. Using an IR rain sensor, the system detects rainfall intensity and adjusts wiper speed automatically, halting when rain stops. It also offers manual control with a rotary switch for three speed levels. Built with an automotive microcontroller, stepper motor, and driver, this prototype enhances convenience and safety during heavy rain.
