• G05D 1/241 Means for detecting physical contact, e.g. touch sensors or bump sensors
• G05D 1/242 Means based on the reflection of waves generated by the vehicle
• G05D 1/243 Means capturing signals occurring naturally from the environment, e.g. ambient optical, acoustic, gravitational or magnetic signals
• G05D 1/244 using passive navigation aids external to the vehicle, e.g. markers, reflectors or magnetic means
• G05D 1/245 using dead reckoning
• G05D 1/246 using environment maps, e.g. simultaneous localisation and mapping [SLAM]
• G05D 1/247 using signals provided by artificial sources external to the vehicle, e.g. navigation beacons
