What causes it to go off course?
In order for autonomous vehicles to participate safely in road traffic, they must be able to reliably recognise road signs. To this end, they are fed large amounts of training data. However, if this data is manipulated – for example, by altering pixels in images – the driver assistance system can be misled. In the worst-case scenario, a stop sign could be interpreted as a 'give way' sign or a tampered sticker could be taken as a signal to 'go full throttle'. Researchers at the DLR Institute for AI Safety and Security are developing methods to protect the AI algorithms of such applications against such 'data poisoning' – to ensure that vehicles do not go down the wrong track.
