Driver assistance system having an emergency stopping function for a vehicle, vehicle having said driver assistance system, and method for the emergency stopping of a vehicle
A driver assistance system has an emergency stopping function for a motor vehicle. The driver assistance system is designed to perform an automated lane change from a first lane to a second lane when the emergency stopping function is triggered. The driver assistance system is further designed to determine at least one road characteristic and/or at least one vehicle interior characteristic and, based on the determined at least one road characteristic and/or the vehicle interior characteristic, to decide whether to execute the lane change.
1. A driver assistance system having an emergency stopping function for a vehicle, wherein the driver assistance system is configured to:
execute an automated lane change from a first lane to a second lane in response to the emergency stopping function being triggered;
determine, using one or more sensors, a speed limit and/or at least one vehicle passenger compartment characteristic;
execute the lane change based on the determined speed limit being higher than a threshold value and/or at least one vehicle passenger compartment characteristic;
execute a risk assessment for the automated lane change based on the determined speed limit and/or at least one vehicle passenger compartment characteristic; and
execute the lane change if the risk assessment is positive.
2. The driver assistance system according to claim 1 , wherein
the driver assistance system is further configured to:
not execute the lane change if surroundings data detected by the one or more sensors indicates that the second lane is present and the risk assessment is negative.
3. The driver assistance system according to claim 1 , wherein
the executed lane change is further based on a road characteristic selected from at least one of:
a structural separation between the vehicle's own roadway and an oncoming roadway;
a number of lanes;
an upcoming routing or bend of the road;
a roundabout;
an intersection;
a toll gate;
a freeway entry slip lane; or
a freeway exit slip lane.
4. The driver assistance system according to claim 1 , wherein
the at least one vehicle passenger compartment characteristic comprises a presence of a driver in a passenger compartment of the vehicle.
5. A motor vehicle comprising the driver assistance system according to claim 1 .
6. A driver assistance system having an emergency stopping function for a vehicle, wherein the driver assistance system is configured to:
execute an automated lane change from a first lane to a second lane in response to the emergency stopping function being triggered;
determine, using one or more sensors, a speed limit and/or at least one vehicle passenger compartment characteristic;
execute the lane change based on the determined speed limit being higher than a threshold value and/or at least one vehicle passenger compartment characteristic; and
execute the emergency stopping function in the first lane based on a determination that a lane change is not to be executed based on the determined speed limit and/or the at least one vehicle passenger compartment characteristic;
execute a risk assessment for the automated lane change based on the determined speed limit and/or the at least one vehicle passenger compartment characteristic; and
execute the lane change based on the risk assessment.
7. A driver assistance system having an emergency stopping function for a vehicle, wherein the driver assistance system is configured to:
execute an automated lane change from a first lane to a second lane in response to the emergency stopping function being triggered;
determine, using one or more sensors, a speed limit and/or at least one vehicle passenger compartment characteristic;
execute the lane change based on the determined speed limit being higher than a threshold value and/or at least one vehicle passenger compartment characteristic;
detect a presence of a driver in a passenger compartment of the vehicle;
when the emergency stopping function is triggered, execute the automated lane change from the first lane to the second lane based on the detected presence of the driver; and
execute the emergency stopping function in the first lane if it is detected that the driver is not present.
8. A method for performing an emergency stop of a vehicle, comprising:
determining, using one or more sensors, a speed limit and/or at least one vehicle passenger compartment characteristic;
executing an automated lane change from a first lane to a second lane based on the determined speed limit being higher than a threshold value and/or at least one vehicle passenger compartment characteristic;
executing a risk assessment for the automated lane change based on the determined speed limit and/or at least one vehicle passenger compartment characteristic; and
executing the lane change if the risk assessment is positive.
9. The method according to claim 8 , further comprising:
not executing the lane change if surroundings data of the one or more sensors indicates that the second lane is present and the risk assessment is negative.
10. The method according to claim 8 , wherein
the executed lane change is further based on a road characteristic selected from at least one of:
a structural separation between the vehicle's own roadway and an oncoming roadway;
a number of lanes;
an upcoming routing or bend of the road;
a roundabout;
an intersection;
a toll gate;
a freeway entry slip lane; or
a freeway exit slip lane.
11. The method according to claim 8 , wherein
the at least one vehicle passenger compartment characteristic comprises a presence of a driver in a passenger compartment of the vehicle.
12. A method for performing an emergency stop of a vehicle, comprising:
determining, using one or more sensors, a speed limit and/or at least one vehicle passenger compartment characteristic;
executing an automated lane change from a first lane to a second lane based on the determined speed limit being higher than a threshold value and/or at least one vehicle passenger compartment characteristic;
executing the emergency stop in the first lane based on a determination that the lane change is not to be executed based on the determined speed limit and/or the at least one vehicle passenger compartment characteristic;
executing a risk assessment for the automated lane change based on the determined speed limit and/or the at least one vehicle passenger compartment characteristic; and
executing the lane change based on the risk assessment.
13. A method for performing an emergency stop of a vehicle, comprising:
determining, using one or more sensors, a speed limit and/or at least one vehicle passenger compartment characteristic;
executing an automated lane change from a first lane to a second lane based on the determined speed limit being higher than a threshold value and/or at least one vehicle passenger compartment characteristic;
detecting presence of a driver in a passenger compartment of the vehicle;
when the emergency stop is triggered, executing the automated lane change from the first lane to the second lane based on the detected presence of the driver; and
executing the emergency stop in the first lane if it is detected that the driver is not present.
