Abstract
A method for identifying a road condition of a road. A piece of road condition information representing the road condition is determined using a noise level detected by at least one ultrasonic sensor of a vehicle and a bottom echo detected from a road surface in the area of the vehicle.
Claims9
A method for identifying a road condition of a road, the method comprising the following steps:
- detecting a noise level using at least one ultrasonic sensor of a vehicle;
- detecting a bottom echo in an area of the vehicle;
- and
- determining a piece of road condition information representing the road condition using the noise level detected by the at least one ultrasonic sensor of the vehicle and the detected bottom echo,
- wherein a transmitting frequency of the at least one ultrasonic sensor is raised or lowered based on a wind velocity at the at least one ultrasonic sensor.
A method for identifying a road condition of a road, the method comprising the following steps:
- determining a change of a roadway surface in an area of the vehicle using a camera and/or a LIDAR sensor;
- detecting a noise level using at least one ultrasonic sensor of the vehicle;
- and
- determining a piece of road condition information representing the road condition using the noise level detected by the at least one ultrasonic sensor of the vehicle and the determined change of the roadway surface,
- wherein a transmitting frequency of the at least one ultrasonic sensor is raised or lowered based on a wind velocity at the at least one ultrasonic sensor.
A device configured to identify a road condition of a road, the device configured to:
- detect a noise level using at least one ultrasonic sensor of a vehicle;
- detect a bottom echo in an area of the vehicle;
- and
- determine a piece of road condition information representing the road condition using the noise level detected by the at least one ultrasonic sensor of the vehicle and the detected bottom echo,
- wherein a transmitting frequency of the at least one ultrasonic sensor is raised or lowered based on a wind velocity at the at least one ultrasonic sensor.
A non-transitory machine-readable memory medium on which is stored a computer program for identifying a road condition of a road, the computer program, when executed by a computer, causing the computer to perform the following steps:
- detecting a noise level using at least one ultrasonic sensor of a vehicle;
- detecting a bottom echo in an area of the vehicle;
- and
- determining a piece of road condition information representing the road condition using the noise level detected by the at least one ultrasonic sensor of the vehicle and the detected bottom echo,
- wherein a transmitting frequency of the at least one ultrasonic sensor is raised or lowered based on a wind velocity at the at least one ultrasonic sensor.
