DRIVER-ASSISTANCE SYSTEM FOR PERFORMING A LANE CHANGE HAVING A ROTATING LIDAR SENSOR ON A ROOF OF A VEHICLE

1 . A driver-assistance system for assisting a driver of a vehicle in performing a lane change of the vehicle, the driver-assistance system comprising:

a sensor system for detecting a further vehicle located in an environment of the vehicle, the sensor system includes a continuously spinning Lidar sensor mounted on a roof of the vehicle,

wherein the driver-assistance system is configured to:

detect a position of the further vehicle dependent on sensor data generated by the sensor system,

check whether there is enough space for performing the lane change of the vehicle dependent on at least the position of the further vehicle, and

generate a signal for initiating the lane change wherein when there is enough space for performing the lane change.

2 . The driver-assistance system according to claim 1 , wherein the signal for initiating the lane change is in the form of an enabled driver-vehicle-interface for initiating the lane change.

3 . The driver-assistance system according to claim 1 , wherein the driver-assistance system is configured to initiate the lane change autonomously in response to a generation of the signal for initiating the lane change.

4 . The driver-assistance system according to claim 1 , wherein the driver-assistance system further comprises:

an inertial measurement unit (IMU),

wherein the driver-assistance system is configured to:

detect an angle of the vehicle to a surface of a road on which the vehicle is located dependent on further sensor data generated by the IMU, and

determine the position of the further vehicle dependent on the angle of the vehicle to the surface of the road.

5 . The driver-assistance system according to claim 1 , wherein the driver-assistance system is further configured to:

determine a velocity of the further vehicle dependent on the sensor data;

predict a driving path of the further vehicle dependent on the position and the velocity of the further vehicle; and

check whether there is enough space for performing the lane change dependent on the predicted driving path of the further vehicle.

6 . The driver-assistance system according to claim 1 , wherein the driver-assistance system is further configured to:

monitor a movement of the further vehicle dependent on the sensor data; and

abort a performing of the lane change dependent on the movement of the further vehicle.

7 . The driver-assistance system according to claim 1 , wherein:

the sensor data is in the form of a point cloud; and

the driver-assistance system is configured to remove points of the point cloud that represent points located on a surface of a road on which the vehicle is located from the point cloud.

8 . The driver-assistance system according to claim 7 , wherein the driver-assistance system is configured to:

generate coordinates of each point of the point cloud on the basis of a coordinate system of the vehicle,

wherein one axis of the coordinate system of the vehicle forms a plane with a rear axle of the vehicle that is perpendicular to a surface of a road on which the vehicle is located.

9 . A method for assisting a driver of a vehicle in performing a lane change of the vehicle, the method comprising the following steps:

generating sensor data by a sensor system for detecting a further vehicle located in an environment of the vehicle, wherein the sensor system includes a continuously spinning Lidar sensor mounted on a roof of the vehicle;

detecting a position of the further vehicle dependent on the sensor data;

checking whether there is enough space for performing the lane change of the vehicle dependent on at least the position of the further vehicle; and

generating a signal for initiating a performing of the lane change wherein when there is enough space for performing the lane change.

10 . A computer program product comprising a computer-readable storage medium having computer-readable program code embodied therewith, wherein the computer-readable program code is configured to:

generate sensor data by a sensor system for detecting a further vehicle located in an environment of the vehicle, wherein the sensor system includes a continuously spinning Lidar sensor mounted on a roof of the vehicle;

detect a position of the further vehicle dependent on the sensor data;

check whether there is enough space for performing the lane change of the vehicle dependent on at least the position of the further vehicle; and

generate a signal for initiating a performing of the lane change wherein when there is enough space for performing the lane change.
