Patents by Inventor Ralf Endress

Ralf Endress has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Offset calibration of a semi-relative steering wheel angle sensor
    Patent number: 6895357
    Abstract: A new method for determining an actual steering wheel angle is provided that does not require re-calculation of a steering center upon each ignition of the vehicle. Accordingly, the vehicle dynamic controller may be activated very quickly after ignition, while a less costly relative steering wheel angle sensor may be employed.
    Type: Grant

  • Regulating circuit for regulating the driving stability of a motor vehicle using a motor vehicle reference model
    Patent number: 6502014
    Abstract: The present invention relates to a control circuit for controlling the driving stability of a vehicle where the input quantities determining the course of track are input in a vehicle model circuit which determines at least on nominal value for a control quantity subject to parameters memorised in the vehicle reference model on the basis of a vehicle reference model reproducing the characteristics of the vehicle.

  • Process for determining ideal vehicular performance
    Patent number: 6233505
    Abstract: In order to adapt a simplified vehicle model to the driving behavior of a real automotive vehicle, it is possible to modify the slip rigidity values assumed to be constant in a linear model. After departure from the linear range of the lateral-force/slip-angle characteristic, a lower value can be assumed for the slip rigidities. However, this will involve the risk that the wheels of the rear axle are already in a slip angle range to which the lower slip rigidity is associated whereas the front wheels are still in the linear range of the lateral-force/slip-angle characteristic. This would impart to the vehicle model an oversteering behavior which should the more so be avoided if such a vehicle model is used for presetting the nominal value. This problem is solved, in the practice of the invention, by suggesting to modify only the slip rigidity values of the front axle while the ones of the rear axle are assumed to be constant.
