  • Process and device for estimating the seriousness of accident occurrences
    Patent number: 7471998
    Abstract: The invention concerns a process and a device for estimating the seriousness of an accident occurrence using parameters regarding the condition of movement of a vehicle during the occurrence of the accident. Therein, the time progression of the parameters regarding movement status of the vehicle are employed for estimation of the seriousness of the accident occurrence.
    Type: Grant
    Filed: July 8, 2004
    Date of Patent: December 30, 2008
    Assignee: Daimler AG
    Inventors: Ravindra Peravali, Juergen Dickmann, Moheb Mekhaiel
  • Method for determining a state of a road during the driving mode of a motor vehicle
    Patent number: 6954146
    Abstract: In a method for determining the state of a road during driving of a motor vehicle, the sound which is generated when a vehicle tire rolls on an underlying surface is sensed. A frequency signal is determined by means of a sound level signal which describes the sound, and is divided into at least two sub-zones by means of at least one limiting frequency. The sub-zones are each assigned to an associated frequency band, and an intensity value is determined for each of at least two frequency bands from the assigned sub-zone of the frequency signal. The intensity value is characteristic of the sound intensity which is present in a frequency band. An intensity ratio is formed from two intensity values by dividing the first intensity value of the first frequency band by the second intensity value of the second frequency band, and is used to determine the state of a road.
