  • Case A-01, Germany

Secure firmware and OTA updates for 120,000 vehicles

In this illustrative example, 8 embedded specialists would build secure-boot firmware and an OTA pipeline for a German Tier-1 supplier. The rollout would reach 120,000 units with zero safety regressions.

OTA rollout to 120k units

In short

Case A-01 is an illustrative example the connected-vehicle firmware programme a Remote Pro Ai squad would deliver for an automotive Tier-1 supplier in Germany. 8 embedded specialists would build secure-boot firmware, an over-the-air update pipeline and hardware-in-the-loop test automation, working in TISAX-aligned environments under ISO 26262 processes. The OTA rollout would reach 120,000 units with zero safety regressions.

In this illustrative example, a German Tier-1 supplier needs secure boot and OTA updates for its telematics units. 8 specialists would deliver in 14 months.

A field fleet that cannot afford a bricked unit

In this example, the supplier’s telematics units need secure boot and over-the-air updates before a vehicle-maker programme deadline. Its in-house embedded team is fully committed to the next hardware generation.

A failed update in the field would mean workshop visits at the vehicle-maker’s cost. The vehicle-maker also expects TISAX-aligned handling of its information and ISO 26262 evidence for every safety-relevant change.

  • Secure boot with a hardware root of trust
  • Updates that recover safely from power loss mid-install
  • TISAX-aligned environments for all vehicle-maker information
  • ISO 26262 work products for every safety-relevant change

These figures are illustrative
they show the kind of result this squad model is built to deliver, not a verifiable named-client record. Rollout counts units confirmed on the new firmware through fleet telemetry. Safety regressions are issues classified as safety-relevant in the supplier’s ISO 26262 process after release. TISAX alignment reflects work carried out entirely inside the supplier’s assessed environments.

Each unit holds 2 firmware partitions. The update writes to the inactive partition, verifies its signature and switches only after a successful boot check. If power fails or the check fails, the unit boots the previous image automatically. HIL rigs would test these failure cases on every build.

The squad would work only on the supplier’s managed devices inside its TISAX-aligned environment, so vehicle-maker information never leaves the supplier’s control. Access is logged and reviewed. Remote Pro Ai keeps no copies of source code, keys or documents on its own systems.

Yes. The squad works inside the supplier’s safety process rather than alongside it. Every safety-relevant change produces the required work products, such as safety analyses and verification records, and passes the supplier’s safety reviews. The embedded lead would also attend the supplier’s safety board before each release.

Keys stay in the supplier’s custody, anchored in a hardware root of trust on each unit. The squad’s security engineer would design the signing flow so that only signed A/B images can boot, and every signing operation is logged. No keys, source code or documents are copied to Remote Pro Ai systems at any point.

Units receive the new firmware in waves during months 12 to 14. Each wave starts small, and fleet telemetry confirms successful installs and boot checks before the next, larger wave begins. Failed installs roll back automatically to the previous image. The illustrative rollout figure counts only units confirmed on the new firmware through telemetry.
