Abstract
Systems and methods are disclosed for an ADV to leverage pre-defined static objects along a planned route of travel to detect and counter attacks that attempt to change the destination or the planned route. The ADV may detect updates to the static objects if the planned route is changed. Based on the updated static objects, the ADV determines if there is an abnormal re-routing of the planned route or if there is a new route due to a suspicious destination change. The ADV may also leverage the static objects to detect spoofing attacks against the sensor system. The ADV may evaluate if sensors of the sensor system are able to detect and identify the static objects to identify an impaired sensor. The ADV may perform cross-check on the ability of the sensors to detect and identify dynamic objects to gain confidence that the impaired sensor is due to spoofing attacks.
