Abstract
A method for determining an incline of a road on which a vehicle is located includes importing image data of an environment of the vehicle, the image data being generated by an image sensor. The method further includes identifying a defined reference object in the environment of the vehicle from the image data and identifying a relationship between the identified reference object and a defined reference system of the image sensor. The method also includes estimating the incline of the road on the basis of the identified relationship and providing a signal representing the incline of the road.
Claims15
A method for determining an incline of a road on which a vehicle is located, comprising:
- importing image data of an environment of the vehicle, the image data generated by an image sensor mounted on the vehicle;
- identifying a defined reference object in the environment of the vehicle from the imported image data, the defined reference object having a fixed position relative to the road;
- identifying a relationship between the identified defined reference object and a defined reference system of the image sensor;
- estimating the incline of the road on which the vehicle is located based on the identified relationship;
- and
- providing a signal representing the estimated incline of the road on which the vehicle is located.
A method for operating a braking device of a vehicle, the method comprising:
- identifying an insufficient calculation of an incline of a road using an acceleration sensor;
- using image data to identify the incline of the road in response to identifying the insufficient calculation by:
- (i) importing image data of an environment of the vehicle, the image data being generated by an image sensor,
- (ii) identifying a defined reference object in the environment of the vehicle from the imported image data,
- (iii) identifying a relationship between the identified defined reference object and a defined reference system of the image sensor, and
- (iv) estimating the incline of the road based on the identified relationship, providing the signal estimating the incline of the road to an assistance system;
- and
- controlling the assistance system in consideration of the signal estimating the incline of the road.
A device for determining an incline of a road on which a vehicle is located, wherein the device is configured to carry out a method under normal conditions of use, the method including:
- importing image data of an environment of the vehicle, the image data being generated by an image sensor mounted on the vehicle;
- identifying a defined reference object in the environment of the vehicle from the imported image data, the defined reference object having a fixed position relative to the road;
- identifying a relationship between the identified defined reference object and a defined reference system of the image sensor;
- estimating the incline of the road on which the vehicle is located based on the identified relationship;
- and
- providing a signal representing the estimated incline of the road on which the vehicle is located.
