OTA Solution

2

Software Update

Avoid expensive recalls by fixing functionality and security problems rapidly

Create new fancy features and business models

Implement software based model upgrades

Data Collection

Implement predictive maintenance

Establish early feedback loops (e.g. on launch of a new model)

Offer new services based on vehicle data> E.g. collect rain sensor data for local weather reports

Live Diagnostics

Get remote roadside assistance from central vehicle support centers> Continue drive or keep waiting for the towing service?

> Solve some EE issues immediately

Security

Only authorized and verified data shall be flashed by authorized persons

Only authorized entities shall be able to collect data from a vehicle

Only authenticated and authorized users should be a able to diagnose a vehicle

Robustness

Reprogramming of a vehicle shall never fail due to remote communication issues

Reprogramming has to be fail safe, rollback strategies are needed in case of problems

Updates have to be reliable, the system must detect whether vehicles missed an update

Efficiency

The footprint of OTA components in the vehicle should be small (network and ECUs)

Data Collection should use resources of vehicle, backend and connection economically

Live Diagnostics should not impose high requirements on the connection

Responsiveness

Live Diagnostics via OTA should be almost as responsive as a local tester

Requirements for automotive OTA – Security is essential
