Objective
A leading Asian OEM collaborated with AVIN Systems to implement a secure Over-the-Air (OTA) update solution for vehicle ECUs. The existing reprogramming systems required manual intervention and lacked cybersecurity protection. AVIN developed an AUTOSAR-based OTA system integrating cloud services with in-vehicle ECUs.
Solution
Requirement Analysis & Configuration
Defined cloud-integrated OTA architecture using AUTOSAR Adaptive UCM. Customized configurations for secure firmware delivery.
Network Management and Development
Enabled encrypted data transmission over CAN/Ethernet using DoIP and TLS.
Memory and Bootloader Integration
Developed rollback-capable bootloaders with version control. Ensured reliable update deployment.
Security Enhancement
Applied HTTPS-based authentication and secure session management. Met OEM cybersecurity benchmarks.
Testing and Validation
Validated OTA workflows using automated test frameworks. Achieved 50% faster deployment cycles.
Impacts
- Reduced update deployment time by 50%.
- Enabled secure, remote ECU updates over CAN/Ethernet.
- Improved update success rate with rollback and version management features.
