The on-center torque adjustment compensation is configured to compensate for inertia of a steering actuator motor using a frequency-based methodology. The control system also includes a second module configured to generate a command signal to control the steering actuator motor of the electric power steering system based on the on-center torque adjustment compensation. | 09-12-2013 |
20130253765 | SYSTEM FOR INDICATING AN IMPENDING VEHICLE MANEUVER - A system for indicating an impending vehicle maneuver within a predetermined distance is provided. The system includes a navigational system and a control module. The navigational system receives a vehicle destination and determines a current geographical vehicle position. The navigational system determines if the impending vehicle maneuver is required within the predetermined distance based on the vehicle destination and the current geographical vehicle position. The control module is in communication with the navigational system and a handwheel. The control module sends a signal that creates a steering assist torque in the handwheel if the impending vehicle maneuver is required. | 09-26-2013 |
20140257639 | CROSS CHECK STRATEGY FOR SYSTEMATIC ERROR PROTECTION - A method for generating and verifying an output command for using in a power steering system is provided. The method receives, by a module having at least a primary processing path and a secondary processing path that is in parallel with the primary processing path, a set of input signals. In the primary processing path, the method generates a primary output command based on the set of input signals and sends the primary output command out of the module. In the secondary processing path, the method generates a first range of command values based on the set of input signals, determines whether the primary output command falls within the range of command values, and generates a fault signal based on determining that the primary output command does not fall within the first range of command values. | 09-11-2014 |
20140277945 | SYSTEM FOR PROVIDING ASSIST TORQUE BASED ON A VEHICLE STATE - A control system for providing an assist torque is provided. The control system includes a control algorithm module and a comfort limit module. The control algorithm module calculates a corrective steering torque based on a target vehicle state and an estimated vehicle state. The comfort limit module receives a handwheel torque. The comfort limit module calculates a limited corrective steering torque based on the corrective steering torque and the handwheel torque. The limited steering torque represents an allowable amount of the assist torque provided by the control system. | 09-18-2014 |
20150142268 | SYSTEMATIC ABNORMALITY DETECTION IN CONTROL COMMANDS FOR CONTROLLING POWER STEERING SYSTEM - A method of mitigating abnormalities in a first control command for controlling a power steering system is provided. The method generates a range signal indicative of a range of command values based on a plurality of input signals. The method determines whether the first control command is out of the range for longer than a predetermined duration of time. The method limits the first control command to the range and sends the limited first control command to the power steering system in response to determining that the first control command is out of the range for shorter than or equal to the duration of time. | 05-21-2015 |

20080221024 | Analogs of Shk Toxin and Their Uses in Selective Inhibittion of Kv1. 3 Potassium Channels - Analogs of ShK toxin and methods for using such ShK analogs. The ShK analogs generally comprise ShK toxin attached to a chemical entity (e.g. an atom, molecule, group, residue, compound, moiety, etc.) that has an anionic charge. In some embodiments the chemical entity attached to the ShK toxin may comprise an amino acid residue. The ShK analogs may be administered to human or non-human animal subjects to cause inhibition of potassium channels or to otherwise treat diseases or disorders. In some embodiments, the chemical entity to which the ShK toxin is attached may be chosen to provide selective inhibition of certain potassium channels (e.g., Kv1.3 channels) over other potassium channels (e.g., Kv1.1 channels). In come embodiments, the chemical entity to which the ShK toxin is attached may include a fluorophore, thereby providing a fluorophore tagged ShK analog.
