## Abstract

A method for vehicle control. The method includes a step of reading in a camera signal, a step of executing a semantic segmentation, and a step of ascertaining a control signal. The camera signal represents an optically detected image of a roadway to be driven by a vehicle. In the step of executing, the semantic segmentation of the image represented by the camera signal is executed, to detect a free area ahead of the vehicle from the image as a drivable road section. In addition, a roadway signal representing the detected drivable road section is provided. In the step of ascertaining, the control signal for activating at least one vehicle component is ascertained, using the roadway signal.

## Claims

### Claim 1

A method for vehicle control, the method comprising the following steps:
reading in a camera signal representing an optically detected image of a roadway to be driven by a vehicle;
executing a semantic segmentation of the image represented by the camera signal to detect a free area ahead of the vehicle from the image as a drivable road section, and providing a roadway signal representing the detected drivable road section; and
ascertaining a control signal for activating at least one vehicle component, using the roadway signal.

### Claim 2 (depends on 1)

The method as recited in claim 1, wherein, in the step of ascertaining, the control signal is additionally ascertained using a marking signal, the marking signal representing an identified lane marking.

### Claim 3 (depends on 1)

The method as recited in claim 1, wherein, in the step of ascertaining, the control signal is ascertained additionally using a vehicle identification signal, the vehicle identification signal representing a detected preceding vehicle.

### Claim 4 (depends on 1)

The method as recited in claim 1, wherein the step of executing the semantic segmentation is executed repeatedly to detect an occurrence of a change of an extension of the drivable road section, and an extension signal is provided which represents the detected change of the extension of the detected drivable road section, the control signal being ascertained using the extension signal in the step of ascertaining.

### Claim 5 (depends on 1)

The method as recited in claim 1, wherein, in the step of ascertaining, the control signal is ascertained to activate a transverse guidance of the vehicle within the detected drivable road section.

### Claim 6 (depends on 1)

The method as recited in claim 1, wherein, in the step of ascertaining, the control signal is ascertained to activate a longitudinal guidance of the vehicle with respect to a detected end of the detected drivable road section.

### Claim 7 (depends on 1)

The method as recited in claim 1, wherein, in the step of ascertaining, the control signal is ascertained as a function of a threshold value with respect to a minimal width or length of the detected drivable road section.

### Claim 8 (depends on 7)

The method as recited in claim 7, wherein, in the step of ascertaining, a warning signal for outputting an acoustically and/or visually perceptible warning to the driver is additionally ascertained, as a function of the threshold value.

### Claim 9 (depends on 1)

The method as recited in claim 1, wherein, in the step of ascertaining, the control signal is ascertained, using a read-in trip parameter, to set a trip parameter.

### Claim 10 (depends on 1)

The method as recited in claim 1, further comprising:
optically detecting the roadway to be driven by the vehicle, using a monocamera sensor unit, to provide the camera signal.

### Claim 11

A device for vehicle control, the device configured to:
read in a camera signal representing an optically detected image of a roadway to be driven by a vehicle;
execute a semantic segmentation of the image represented by the camera signal to detect a free area ahead of the vehicle from the image as a drivable road section, and provide a roadway signal representing the detected drivable road section; and
ascertain a control signal for activating at least one vehicle component, using the roadway signal.

### Claim 12

A non-transitory machine-readable memory medium on which is stored a computer program for vehicle control, the computer program, when executed by a computer, causing the computer to perform the following steps:
reading in a camera signal representing an optically detected image of a roadway to be driven by a vehicle;
executing a semantic segmentation of the image represented by the camera signal to detect a free area ahead of the vehicle from the image as a drivable road section, and providing a roadway signal representing the detected drivable road section; and
ascertaining a control signal for activating at least one vehicle component, using the roadway signal.
