A method of developing a road conditioning monitoring model is disclosed. The method comprises utilizing vehicle sensors to collect data under controlled conditions over a road surface to develop a training data set. The training data set undergoes a data analysis to determine an absolute running mean associated with the first road surface under controlled conditions. Abnormalities in the road surface are detected by comparing the absolute running mean with the training data set. The detected abnormalities are classified to create road surface classification rules. A method of developing a road condition database is also disclosed, that comprises utilizing vehicle sensors during operation of a vehicle to collect data during the operation and feeding the data into the road conditioning monitoring model to classify the road conditions on which the vehicle is driven. A system for determining road condition impact on a vehicle is also disclosed.

Method of determining parameters of interaction between a vehicle and a road

Disclosed is a load detection device and method using the same. In one example, the device includes a height-level measuring unit configured to determine a height level of a vehicle and to generate at least one height-level signal that characterizes the height level. A position-measuring unit is configured to determine the position of the vehicle relative to the mid-point of the earth and to generate at least one position signal that characterizes the vehicle position. An evaluation unit is coupled to the height-level measuring unit and to the position-measuring unit. The evaluation unit is configured to determine a mass of a load of the vehicle, taking into account the height-level signal(s) and the position signal(s). The device can be used to determine the mass of the load, which may include a number of persons.

Load detection device

A method for checking the tire pressure of a vehicle (), which vehicle comprises at least one vehicle wheel () and a vehicle body () which is supported elastically on the vehicle wheel (). The wheel includes a tire (), filled with gas, on which wheel the vehicle stands on a subsurface (). The vehicle body () is loaded with an additional mass and thereby the vehicle body is stimulated into a mechanical oscillation () relative to the subsurface (). A response signal (A), that characterizes the mechanical oscillation (), is measured and analyzed, whereby at least one response value that characterizes the current gas pressure in the tire is determined.
