- Condition information a driving behavior of the first vehicle. This can be, for example, a roll or a strong deceleration.
- State information concerning a driving behavior of the first vehicle is updated in the electronic map based on a speed and / or a current position of the first vehicle.
- the position of the lurching vehicle can be transmitted updated to a following vehicle based on its movement data.
- the status information is calculated from sensor data from sensors located in the first vehicle.
- the first vehicle can be used as a sensor, so to speak, to determine crosswind, ruts, aquaplaning, trailer lugs or loose wheel bolts as condition information.

- the SWA Assistant can also use the information 24, 26 to validate a situation. If e.g. If a rut is mistakenly interpreted as a crosswind, this would result in a malfunction of the SWA assistant. However, if it is known that there are ruts, an activation threshold for the SWA assistant can be increased.
