Software-defined vehicle
What it is
A vehicle whose features are defined by software running on centralised or zonal computing, rather than by fixed hardware in dozens of separate control units. Capability can be added or changed after sale through over-the-air updates
It requires a re-architected electrical system, an operating layer above it, cybersecurity by design, and a validation approach closer to software release than vehicle testing
Impact on industries
- Shifts value from the sale to the ownership period - features, upgrades and subscriptions can be sold post-purchase, creating recurring revenue where none existed
- Plays to India's twin strengths of software talent and manufacturing depth - domestic engineering-services firms now sell SDV stacks to global OEMs
- Suppliers must sell functions rather than parts, stranding component makers organised around discrete hardware and favouring electronics and software capability
- Ongoing liability - OTA means the maker owns cybersecurity and software support for the vehicle's life, a risk with no precedent in the ICE model
