Heritage brand, electrified — and cyber-secure.
Tomco led the functional-safety and cybersecurity case for a heritage motorcycle manufacturer's electrification and connectivity program — ISO 26262 layered with ISO/SAE 21434 and UNECE R155/R156 over-the-air evidence.
How the engagement ran.
The client — a heritage motorcycle manufacturer — was moving its flagship platform to a connected electric powertrain with always-on telemetry and over-the-air update capability. The combined system required ISO 26262 for the powertrain, ISO/SAE 21434 for the cybersecurity case, and UNECE R155 / R156 type-approval evidence for cyber and software-update management.
Tomco built a single integrated safety + security case rather than two parallel ones. AFSPs and certified cybersecurity engineers co-signed the TARA, the cyber requirements, the OTA campaign-management evidence, and every release of the connected powertrain firmware. Agents kept the trace continuous across vehicle, cloud, and mobile-companion-app boundaries.
First connected electric models shipped on schedule with full R155/R156 type approval. The integrated safety + cyber case is now the client's house standard for every connected vehicle program in the pipeline.
