  • Patent number: 11679717
    Abstract: The present disclosure relates to a method for operating a haptic system, the haptic system comprising at least one actuator and at least one haptic control device adapted to control the at least one actuator and to provide haptic feedback to a user, the method comprising the steps of: obtaining, from a feedback computational model, modelled feedback data, obtaining, from a feedback estimator, estimated feedback data based on measurement data determined from measurement made on the haptic system, overlaying the modelled feedback data and the estimated feedback data to generate blended feedback data, and providing the blended feedback data to control the haptic feedback to the user.

  • Publication number: 20230166789
    Abstract: In one or more embodiments described herein, devices, systems, methods and/or apparatuses are described that can facilitate provision of a single motor torque request based on a driver assistance system pinion angle request. The motor torque request can be generated absent arbitration between two or more requests from two or more different controller components. A device can comprise a steering control system that generates a motor torque request based on a single request from a single first controller component.

  • Patent number: 8065067
    Abstract: The present invention refers to systems and to methods for determining at least one parameter relating to a tire-to-road contact and/or a relation between a wheel and a vehicle motion. In particular, the present invention refers to systems and to methods for determining the coefficient of friction between a tire and a road surface. For that purpose, the systems and methods according to the invention use new estimation filtering procedures.
