Abstract: A method for determining a state of wear of a brake pad of a vehicle. The method includes: receiving time series data, the time series data including a time series of brake system-related data of the vehicle; identifying at least one braking event in the time series data, each braking event identified in the time series data corresponding to a temporal data window of braking event data of the time series data, the data window correlating with a real braking event of the vehicle; determining features from the braking event data by using predetermined operators for each identified braking event; classifying the at least one braking event by using the features determined for this purpose, the classification being associated with a state of wear of the brake pad of the vehicle.

Abstract: A method for determining and characterizing road unevenness of a roadway. Sensor data are generated by at least one wheel speed sensor and/or at least one wheel-individual acceleration sensor of a motor vehicle travelling the roadway. The road unevenness is determined and characterized by an arithmetic unit using the sensor data generated.

Abstract: A method for determining and characterizing road unevenness of a roadway. Sensor data are generated by at least one wheel speed sensor and/or at least one wheel-individual acceleration sensor of a motor vehicle travelling the roadway. The road unevenness is determined and characterized by an arithmetic unit using the sensor data generated, thereby determining an edge type of the road unevenness.
