DIDI Rescue Vault — offline vehicle rescue cards for emergency crews

At a road traffic collision the crew has seconds to establish what they are cutting into. Modern vehicles make that harder, not easier: accident damage obscures identifying features, many models are visually near-identical, and petrol, diesel, hybrid, electric and hydrogen drivetrains each carry different risks. High-voltage batteries, gas generators and pressurised tanks are all in different places depending on the exact variant. And mobile coverage at a motorway incident cannot be assumed.

DIDI Rescue Vault holds verified rescue cards locally on the deployed device. Crews identify a vehicle by VIN scan, licence-plate lookup, AI image recognition, or manual search by manufacturer, model, year and drivetrain. Where a vehicle cannot be identified unambiguously, the app shows every matching variant side by side with the hazard areas and safe cutting zones overlaid, rather than forcing a guess. Safety-relevant systems — airbags and gas generators, pretensioners and SRS control units, body reinforcements and rollover protection, low- and high-voltage batteries, fuel and gas tanks, plus truck and bus specifics — are surfaced directly instead of buried in a full rescue card.

Built on the DIDI platform, so cards are centrally managed, cryptographically signed, and synchronised automatically whenever a connection is available. Crews never download or maintain anything by hand, and only authorised devices can access the data. Licence-plate lookup deliberately uses vehicle data only — no personal keeper data is processed.
