Method for operating a vehicle
A method for operating a vehicle includes continuously checking during a driving operation whether an emergency situation is present in the vehicle and, when an emergency situation is detected, initiating an emergency stopping maneuver for safely parking the vehicle, signalling the emergency situation to a road user in a surroundings of the vehicle, and aborting the emergency stopping maneuver when a vehicle user takes over a task of driving the vehicle. The method further includes automatically deactivating the signalling of the emergency situation when an ascertained duration of time between the initiating and the aborting of the emergency stopping maneuver is smaller than a predeterminable time value and/or when an ascertained reduction of a driving speed of the vehicle between the initiating and the aborting of the emergency stopping maneuver is smaller than a predeterminable speed reduction value.
1. A method for operating a vehicle, comprising the steps of: continuously checking during a driving operation whether an emergency situation is present in the vehicle and, when the emergency situation is detected, initiating an emergency stopping maneuver for safely parking the vehicle, signalling the emergency situation to a road user in surroundings of the vehicle, aborting the emergency stopping maneuver when a vehicle user takes over a task of driving the vehicle, and determining whether the vehicle constitutes a danger to road users in the surroundings of the vehicle after the aborting of the emergency stopping maneuver as a result of a reduced vehicle speed due to the emergency stopping maneuver; wherein the signalling of the emergency situation is automatically deactivated after the aborting of the emergency stopping maneuver when it is determined that the vehicle does not constitute the danger to road users in the surroundings of the vehicle after the aborting of the emergency stopping maneuver by determining that an ascertained duration of time between the initiating and the aborting of the emergency stopping maneuver is smaller than a predetermined time value which varies with a driving speed of the vehicle and that an ascertained reduction of the driving speed of the vehicle between the initiating and the aborting of the emergency stopping maneuver is smaller than a predetermined speed reduction value; and wherein the signalling of the emergency situation is continued after the aborting of the emergency stopping maneuver when it is determined that the vehicle does constitute the danger to road users in the surroundings of the vehicle after the aborting of the emergency stopping maneuver.
2. The method according to claim 1 , wherein the signalling is automatically carried out after exceeding the predetermined time value and/or after exceeding the predetermined speed reduction value when the vehicle is accelerated to a driving speed that exceeds a predetermined speed value.
3. The method according to claim 1 , wherein a hands-free driving by the vehicle user and a duration of time of the hands-free driving is recorded to ascertain the emergency situation.
4. The method according to claim 3 , wherein the emergency stopping maneuver is initiated when the duration of time of the hands-free driving exceeds a predetermined time threshold value.
5. The method according to claim 1 , wherein a hazard light or a dipped beam of the vehicle is activated as the signalling.
6. The method according to claim 1 further comprising the step of monitoring the vehicle user by captured image data of a driver observation camera.
7. The method according to claim 1 , wherein the vehicle is decelerated in its current driving lane until the vehicle reaches a standstill when the emergency situation is present and the emergency stopping maneuver is initiated.
8. The method according to claim 1 , wherein when carrying out the emergency stopping maneuver, the driving speed of the vehicle is reduced while taking a further road user in the surroundings of the vehicle into consideration.
