Patent number: 11433942Abstract: A motor vehicle power steering mechanism with an electric motor for steering assist and/or steering, and a steering controller, which controls the electric motor with a position control mode for autonomous driving and/or automatic steering and a torque control mode for manual steering by a driver. The steering controller includes a steering column reference controller, an arbitration unit, a column torque controller, a steering algorithm, and the steering system. The steering column reference controller calculates for position control based on a reference position and a measured position, and a first reference steering column torque. A steering algorithm calculates for torque control based on a measured column torque and a second reference steering column torque. The arbitration unit weights and adds the first and second reference steering column torques, and the output of the arbitration unit is input to the column torque controller.Type: GrantFiled: February 22, 2017Date of Patent: September 6, 2022Assignees: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventors: Csaba Fazekas, Ádám Varga, Imre Benyó

Publication number: 20220250679Abstract: A method for controlling a steer-by-wire steering system involves determining a torque request signal with a position controller based on desired and actual steering angles, checking with a checking device for an error state of the position controller, selecting the torque request signal as a checked torque request signal if the error state has not been determined, selecting a reference torque signal as the checked torque request signal if the error state has been determined, and transmitting the checked torque request signal to the steering actuator. By evaluating a cumulative deviation variable, which is calculated by a calculation unit of the checking device as a time integral over a control deviation between the desired and actual steering angles, the checking device determines whether the error state is present and determines the reference torque signal with a reference controller based on the control deviation.Type: ApplicationFiled: March 2, 2020Publication date: August 11, 2022Applicants: thyssenkrupp Presta AG, thyssenkrupp AGInventors: Peter KAKAS, Àdám VARGA, Daniel VIZER

Patent number: 11390317Abstract: A disclosed method can control an electric motor for an electromechanical power steering mechanism for assisting steering for a motor vehicle. The electromechanical power steering mechanism may include a steering column with an upper steering shaft linked to a lower steering shaft by a torsion bar. A torsion angle between the upper steering shaft and the lower steering shaft is configured to be measured or estimated, and an electric motor is configured to apply an assistance torque. The method may involve calculating a desired rotor position with an assist algorithm based on the torsion angle and calculating a PWM pattern by a PWM control unit such that the calculated PWM pattern adjusts a rotor of an electric motor angle such that the torsion angle is decreased.Type: GrantFiled: September 13, 2017Date of Patent: July 19, 2022Assignees: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventors: Ádám Varga, Gábor Kalapos, Márton Helli, Csaba Fazekas

The electric motor is configured to apply an assistance torque in response to an output signal from the torque sensor indicative of the input torque applied by a driver of the vehicle to a steering wheel, in which the relationship between the indicated input torque and the assistance torque applied by the motor is defined by a boost curve. A logical summer is used to restrict the relationship between the indicated input torque and the assistance torque within given safety limits.Type: GrantFiled: January 13, 2017Date of Patent: July 5, 2022Assignees: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventors: Adám Varga, Péter Kakas

Publication number: 20220144334Abstract: A method for controlling a steer-by-wire steering system for a motor vehicle may involve determining a torque request signal with a position controller of an activation unit based at least on a desired steering angle and an actual steering angle, limiting the torque request signal in a signal limiting device of the activation unit such that the torque requested by the limited torque request signal is limited to a permissible torque range, and transmitting the limited torque request signal to an electronically controllable steering actuator. The signal limiting device may determine a reference torque signal by way of a reference controller based at least on the desired steering angle and the actual steering angle. The signal limiting device may define the permissible torque range by way of a selectable maximum deviation from the reference torque signal.Type: ApplicationFiled: March 2, 2020Publication date: May 12, 2022Applicants: thyssenkrupp Presta AG, thyssenkrupp AGInventors: Peter KAKAS, Àdám VARGA, Daniel VIZER

Patent number: 11170576Abstract: A progressive display system can compute a virtual distance between a user and virtual objects. The virtual distance can be based on: a distance between the user and an object, a viewing angle of the object, and/or a footprint of the object in a field of view. The progressive display system can determine where the virtual distance falls in a sequence of distance ranges that correspond to levels of detail. Using a mapping between content sets for the object and levels of detail that correspond to distance ranges, the progressive display system can select content sets to display in relation to the object. As the user moves, the virtual distance will move across thresholds bounding the distance ranges. This causes the progressive display system to select and display other content sets for the distance range in which the current virtual distance falls.Type: GrantFiled: September 20, 2019Date of Patent: November 9, 2021Assignee: Facebook Technologies, LLCInventors: Jonathan Ravasz, Etienne Pinchon, Adam Varga, Jasper Stevens, Robert Ellis, Jonah Jones

Patent number: 11086406Abstract: A hand interaction system can use a three-state model to differentiate between normal hand movements, such as reaching for an object, and hand input gestures. The three-state model can specify a sequence of states including: 1) a neutral state, 2) a tracking state, and 3) an active state. In the neutral state, the hand interaction system monitors for a gesture signaling a transition to the tracking state but does not otherwise interpret a gesture corresponding to the active state as input. Once a gesture causes a transition to the intermediate tracking state, the hand interaction system can recognize a further active state transition gesture, allowing active state interaction. Thus, the monitoring for the intermediate tracking state provides a gating mechanism, making it less likely that the hand interaction system will interpret hand movements as input when not so intended by the user.Type: GrantFiled: September 20, 2019Date of Patent: August 10, 2021Assignee: Facebook Technologies, LLCInventors: Jonathan Ravasz, Etienne Pinchon, Adam Varga, Jasper Stevens, Robert Ellis, Jonah Jones

Patent number: 10991163Abstract: The present technology relates to artificial reality systems. Such systems provide projections a user can create to specify object interactions. For example, when a user wishes to interact with an object outside her immediate reach, she can use a projection to select, move, or otherwise interact with the distant object. The present technology also includes object selection techniques for identifying and disambiguating between objects, allowing a user to select objects both near and distant from the user. Yet further aspects of the present technology include techniques for interpreting various bimanual (two-handed) gestures for interacting with objects. The present technology further includes a model for differentiating between global and local modes for, e.g., providing different input modalities or interpretations of user gestures.Type: GrantFiled: September 25, 2019Date of Patent: April 27, 2021Assignee: Facebook Technologies, LLCInventors: Jonathan Ravasz, Etienne Pinchon, Adam Varga, Jasper Stevens, Robert Ellis, Jonah Jones, Evgenii Krivoruchko
