Client Overview
ISUZU, a global leader in commercial and industrial vehicles, continuously innovates to enhance vehicle performance and efficiency. As vehicle software complexity increases, ISUZU sought a robust, scalable, and secure OTA (Over-The-Air) vehicle software updates solution to streamline ECU (Electronic Control Unit) updates across their fleet. The goal was to improve operational efficiency, minimize vehicle downtime, and ensure seamless remote software management while maintaining the highest standards of security and compliance.
Challenges
ISUZU faced several challenges in updating their vehicle software, particularly for their PT series vehicle update projects:
1. Large Update Packages
Modern vehicles, especially electric and connected vehicles, integrate multiple ECUs controlling various subsystems such as powertrain, infotainment, and ADAS (Advanced Driver Assistance Systems). This complexity results in large software update packages, leading to prolonged update times and inefficiencies.
2. Complex ECU Structure
ISUZU’s next-generation trucks contained multiple domain controllers and core ECUs requiring synchronized updates. Traditional update mechanisms struggled with ensuring consistent and coordinated software flashing across all these units without causing system conflicts.
3. High Network Dependency
Deploying software updates in real-world conditions requires overcoming challenges such as unstable network environments, varying bandwidth availability, and potential power loss during updates. Ensuring reliable updates under these constraints was critical to preventing failed deployments and potential vehicle malfunctions.
4. Security and Compliance Requirements
As vehicle software updates become increasingly important, adhering to stringent automotive cybersecurity regulations is paramount. ISUZU needed a solution that not only streamlined updates but also provided enterprise-grade security to prevent unauthorized access and data breaches.
Solution: Redstone OTA
To address these challenges, ISUZU partnered with Redstone OTA to implement an enterprise-grade, highly efficient remote software update solution tailored to their needs. Redstone OTA provided several key capabilities that directly tackled ISUZU’s concerns:
1. Distributed Download Mechanism
Redstone OTA enabled distributed downloads, allowing the same update package to be delivered to different core ECUs and domain controllers concurrently. This significantly reduced the total update time and ensured system-wide consistency.
2. Adaptive Storage Allocation
In cases where an ECU had limited storage capacity, Redstone OTA dynamically adjusted and allocated update packages across multiple ECUs. This eliminated the need for manual intervention, ensuring seamless updates without overloading system memory.
3. Multi-Threaded Parallel Flashing
Redstone OTA’s advanced multi-threaded technology allowed ISUZU to flash software updates over multiple CAN (Controller Area Network) channels in parallel. This approach drastically reduced the overall update time, increasing fleet-wide update efficiency.
4. Multi-Domain Parallel Flashing
The solution supported simultaneous software flashing across different ECU domains, ensuring updates were completed quickly without disrupting vehicle functionality. This reduced the risk of bottlenecks in the update process and enhanced overall system stability.
5. Stable Power-Off Protection and Network Continuity
Unexpected power loss or network disconnection during an update could pose serious risks, such as software corruption and vehicle inoperability. Redstone OTA implemented intelligent rollback and resume capabilities, ensuring that updates continued seamlessly once power or connectivity was restored. This feature significantly improved update reliability across ISUZU’s fleet.
6. Enhanced Security & Compliance
Redstone OTA integrated enterprise-grade security measures, including encrypted data transmission, secure authentication protocols, and compliance with global automotive cybersecurity standards such as ISO 21434. This ensured that ISUZU’s software updates remained protected from potential cyber threats.
