Method for assisting a user of a vehicle during automated lateral guidance of the vehicle on a road having multiple lanes, computing device, and driver assistance system
A method for assisting a user of a vehicle during automated lateral guidance of the vehicle on a road having multiple lanes is provided. The method includes receiving satellite-based position data describing a position of the vehicle; determining map-based lane tracking data describing a future desired movement of the vehicle relative to the lanes based on the satellite-based position data and high-resolution map data; receiving sensor data from at least one environment sensor of the vehicle, the sensor data describing boundaries of the lanes; determining sensor-based lane tracking data describing a future desired movement of the vehicle relative to the lanes based on the sensor data; comparing the map-based lane tracking data and the sensor-based lane tracking data; and controlling an output device for outputting a takeover request to the user based on a result of the comparison.
1 . A method for assisting a user of a vehicle during automated lateral guidance of the vehicle on a road having a plurality of lanes, the method comprising:
receiving satellite-based position data that describe a position of the vehicle;
determining map-based lane progression data that describe a future desired movement of the vehicle with reference to the plurality of lanes based on the satellite-based position data and high-resolution map data;
receiving sensor data from at least one surroundings sensor of the vehicle, the sensor data describing boundaries of the plurality of lanes;
determining sensor-based lane progression data that describe a future desired movement of the vehicle with reference to the plurality of lanes based on the sensor data;
comparing the map-based lane progression data and the sensor-based lane progression data; and
triggering an output device to output a takeover request to the user based on a result of the comparison.
2 . The method according to claim 1 , wherein the output device is triggered to output the takeover request based on a determination that a difference between the map-based lane progression data and the sensor-based lane progression data is above a predetermined threshold value.
3 . The method according to claim 2 , wherein route planning for future automated lateral guidance of the vehicle is determined based on the map-based lane progression data and the sensor-based lane progression data and a determination that the difference between the map-based lane progression data and the sensor-based lane progression data is below the predetermined threshold value.
4 . The method according to claim 3 , wherein the difference between the map-based lane progression data and the sensor-based lane progression data is determined continually.
5 . The method according to claim 3 , wherein the takeover request is output in such a way that the vehicle is prevented from leaving the lane until a probable time of takeover by the user.
6 . The method according to claim 2 , wherein the difference between the map-based lane progression data and the sensor-based lane progression data is determined continually.
7 . The method according to claim 2 , wherein the takeover request is output in such a way that the vehicle is prevented from leaving the lane until a probable time of takeover by the user.
8 . The method according to claim 1 , wherein the takeover request is output in such a way that the vehicle is prevented from leaving the lane until a probable time of takeover by the user.
9 . A non-transitory computer-readable medium storing a program including instructions that, when executed by a computing device, cause the computing device to perform a method according to claim 1 .
10 . A computing device for a driver assistance system of a vehicle, wherein the computing device is designed so as, during automated lateral guidance of the vehicle to:
receive satellite-based position data that describe a position of the vehicle;
determine map-based lane progression data that describe a future desired movement of the vehicle with reference to lanes of a road based on the satellite-based position data and high-resolution map data;
receive sensor data from at least one surroundings sensor of the vehicle, the sensor data describing boundaries of the lanes; and
determine sensor-based lane progression data that describe a future desired movement of the vehicle with reference to the lanes based on the sensor data;
wherein the computing device is further designed to compare the map-based lane progression data and the sensor-based lane progression data, and to trigger an output device to output a takeover request to the user based on a result of the comparison.
11 . A driver assistance system for a vehicle, the driver assistance system comprising a computing device according to claim 10 and an output device for outputting a takeover request to a user of the vehicle, the driver assistance system being designed for automated lateral guidance of the vehicle.
