Abstract
In a method for detecting the road condition for a vehicle, the following steps are performed: a vehicle dynamics variable describing the dynamics of the motor vehicle is detected while the vehicle is driving; the vehicle dynamics variable is subjected to a frequency analysis; and a road condition variable describing the instantaneous roughness of the roadway surface is ascertained as a function of the frequency analysis of the vehicle dynamics variable.

A method for detecting the road condition for a vehicle, comprising:
- detecting, by a vehicle sensor device, a vehicle dynamics variable describing the dynamics of the motor vehicle while the vehicle is being driven;
- performing, by a computing device of the vehicle having at least one processor, a frequency analysis of the vehicle dynamics variable, the frequency analysis comprising a first filtering operation, an absolute value calculation operation, and a second filtering operation separate from the first filtering operation;
- and
- ascertaining, by the at least one processor, as a function of the frequency analysis of the vehicle dynamics variable, a road condition variable describing the instantaneous roughness of the roadway surface.
A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer having at least one processor, perform a method for detecting the road condition for a vehicle, the method comprising:
- detecting a vehicle dynamics variable describing the dynamics of the motor vehicle while the vehicle is being driven;
- performing a frequency analysis of the vehicle dynamics variable, the frequency analysis comprising a first filtering operation, an absolute value calculation operation, and a second filtering operation separate from the first filtering operation;
- and
- ascertaining, as a function of the frequency analysis of the vehicle dynamics variable, a road condition variable describing the instantaneous roughness of the roadway surface.
