  • Friction coefficient estimation from camera and wheel speed data
    Patent number: 9643617
    Abstract: A method and an apparatus for estimating a friction coefficient in a moving vehicle analyze image data from a forward-looking vehicle camera to produce a camera friction coefficient ?k, and analyze tire slip and tire vibration based on a wheel speed signal to produce a wheel friction coefficient ?w. The camera and wheel friction coefficients are both considered to produce a proactive estimated friction coefficient that is primarily based on the camera friction coefficient ?k, whereas the wheel friction coefficient ?w is taken into account to check plausibility of the camera friction coefficient ?k.

  • Friction Coefficient Estimation from Camera and Wheel Speed Data
    Publication number: 20150251659
    Abstract: This invention relates to a method and an apparatus, respectively, for estimating a friction coefficient in a moving vehicle. For this purpose, image data from a forward-looking vehicle camera is analyzed in the vehicle so as to allow conclusions with respect to the road surface. The camera image data is used to perform a friction coefficient classification which provides a camera friction coefficient ?k. A tire slip and a tire vibration are analyzed based on a wheel speed signal and are used to perform a classification of the friction coefficient which provides a wheel friction coefficient ?w. Proactive estimation of the friction coefficient is performed as a merger of the camera and wheel friction coefficients, wherein the proactive friction coefficient estimation is primarily based on the camera friction coefficient ?k but the wheel friction coefficient ?w is continuously taken into account to check the camera friction coefficient ?k for plausibility.

  • Tire pressure loss detection
    Patent number: 6993449
    Abstract: The present invention is directed to monitoring the loss of pressure in one or more tires by detecting the angular speed variations of one or more wheels of the vehicle over a specified wheel revolution period and analyzing the vibration of the speed various. Changes in the frequency are related to pressure loss, which is indicated to the driver, for example, by displaying the tire pressure loss information on a display.
