Method for generating a map of the surroundings of a vehicle
A method for generating a map of the surroundings of a vehicle including at least one sensor. First data are acquired by the vehicle, the first data including a position of the vehicle and information about the type of the sensor. The first data are transmitted to a central device by the vehicle. Perception parameters are selected by the central device in view of the transmitted first data. The selected perception parameters are received by the vehicle, and the sensor is configured, using the selected perception parameters. The surroundings of the vehicle are monitored by the sensor, raw data being recorded, and the raw data being filtered by the vehicle, using the selected perception parameters. Second data are transmitted to the central device by the vehicle, the second data representing the monitored surroundings. A map is generated and/or updated by the central device based on the second data.
1. A method for generating a map of surroundings of a vehicle, the vehicle including at least one sensor, the method comprising the following steps:
a) acquiring, by the vehicle, first data, the first data including at least a position of the vehicle and information about a type of the at least one sensor;
b) transmitting, by the vehicle, the first data to a central device;
c) selecting, by the central device, perception parameters in view of the first data;
d) transmitting, by the central device, the selected perception parameters to the vehicle;
e) receiving, by the vehicle, the selected perception parameters, and configuring the at least one sensor using the selected perception parameters;
f) monitoring the surroundings of the vehicle by the at least one sensor, raw data being recorded, and the raw data being filtered by the vehicle, using the selected perception parameters;
g) transmitting, by the vehicle, second data to the central device, the second data being based on the raw data; and
h) generating and/or updating, by the central device, a map based on the second data.
2. The method as recited in claim 1 , wherein the first data include: (i) a vehicle position ascertained using satellite navigation, and/or (ii) an orientation of the vehicle.
3. The method as recited in claim 1 , wherein the first data include information about current environmental conditions at the position of the vehicle, and/or the central device obtains information about current environmental conditions at the position of the vehicle via a meteorological service.
4. The method as recited in claim 1 , wherein during the selection of the perception parameters by the central device in accordance with step c), perception parameters suitable for generating a map are selected as a function of the position of the vehicle, an orientation of the vehicle, and/or current environmental conditions.
5. The method as recited in claim 1 , wherein objects are detected by the vehicle in the filtered raw data, and the second data include filtered raw data and/or detected objects.
6. The method as recited in claim 1 , wherein the second data include the filtered raw data.
7. The method as recited in claim 6 , wherein objects are detected by the central device in the filtered raw data.
8. The method as recited in claim 1 , wherein the generated map is provided to a driver assistance system of the vehicle, at least a section of the map being transmitted to the vehicle by the central device.
9. A central device, comprising:
a computing device; and
a communications device;
wherein the central device is configured to:
receive, from a vehicle having at least one sensor, first data, the first data including at least a position of the vehicle and information about a type of the at least one sensor;
select perception parameters in view of the first data;
transmit the selected perception parameters to the vehicle, the vehicle configuring the at least one sensor using the selected perception parameters, monitoring the surroundings of the vehicle by the at least one sensor, recording raw data, and filtering the raw data using the selected perception parameters;
receive, from the vehicle, second data to the central device, the second data being based on the raw data; and
generate and/or update a map based on the second data.
10. A vehicle, comprising:
at least one sensor; and
a communications unit;
wherein the vehicle is configured to:
acquire first data, the first data including at least a position of the vehicle and information about a type of the at least one sensor;
transmit the first data to a central device, the central device selecting perception parameters in view of the first data, and transmitting the selected perception parameters to the vehicle;
receive the selected perception parameters, and configure the at least one sensor using the selected perception parameters;
monitor the surroundings of the vehicle by the at least one sensor, record raw data, and filter the raw data using the selected perception parameters; and
transmit second data to the central device, the second data being based on the raw data, the central device generating and/or updating a map based on the second data.
11. The vehicle as recited in claim 10 , wherein the at least one sensor is one or more of the following: a radar sensor, or an ultrasonic sensor, or a lidar sensor, or an optical sensor.
