Abstract

The invention relates to a driver assistance system for a motor vehicle including a camera for detecting roadway marking. According to the invention a device is provided for detecting a parked or stopped mode of the vehicle. Furthermore, a control device receives image data of the surroundings of the vehicle from the camera in the parked or stopped mode and analyzes the image data with respect to roadway markings which indicate no-parking and/or no-stopping spots, wherein the control device controls a signaling device such that the signaling device outputs a warning message in the event that a roadway marking indicating a no-parking spot or a no-stopping spot is detected in the surroundings of the stopped or parked vehicle.

First claim

The invention claimed is:

1. A driver assistance system for a motor vehicle including a camera for detecting roadway markings, comprising:
a device, located in the vehicle, for detecting a parking or stopping mode of the vehicle; and
a control device, located in the vehicle, configured to:
1) receive digital map data indicating a location of the vehicle, the location used to determine types of roadway markings associated with a specific place,
2) receive image data of surroundings of the vehicle from the camera in the parking or stopping mode,
3) specify analysis parameters of said image data based on the types of roadway markings associated with the specific place as indicated by the map data, and
4) analyze said image data based on the specified analysis parameters to detect roadway markings which indicate i) a no-parking spot where parking is not permitted by law of the specific place, or a no-stopping spot where stopping is not permitted by law of the specific place, and ii) a parking spot where parking is permitted by law of the specific place, or a stopping spot where stopping is permitted by law of the specific place,

wherein the control device, located in the vehicle, controls a signaling device, located in the vehicle based the analysis, such that the signaling device:
outputs a warning message to a driver of the vehicle in the event that a roadway marking indicating a no-parking spot or a no-stopping spot is detected in the surroundings of the stopping or parking vehicle, and
outputs another message to the driver of the vehicle in the event that a roadway marking indicating a parking spot or a stopping spot is detected in the surroundings of the vehicle.

2. The driver assistance system according to claim 1 , wherein:
the control device controls the signaling device after a predetermined period of time has elapsed with the vehicle in the state of the parking or stopping mode.

3. The driver assistance system according to claim 2 , wherein the predetermined period of time is at least three minutes.

4. The driver assistance system according to claim 1 , comprising:
a further device detecting if the driver leaving the vehicle, wherein
the control device controls the signaling device if the further device detects that the driver is leaving the vehicle.

5. The driver assistance system according to claim 1 , wherein the control unit detects surroundings of the vehicle in the parking or stopping mode only in towns and cities.

6. The driver assistance system according to claim 1 , comprising a device to perform traffic sign recognition with the camera.
