摘要:
A method, system, and computer program product for calculating a torque overlay command in a steering control system is provided. The method includes receiving a current hand wheel angle, receiving a change in vehicle yaw moment command, and calculating a lateral force in response to the change in vehicle yaw moment command. The method also includes determining a new tire side slip angle from the lateral force and calculating a commanded hand wheel angle from the new tire side slip angle. The method further includes calculating an error signal as a difference between the commanded hand wheel angle and the current hand wheel angle, and generating a torque overlay command from the error signal.

A musical instrument mute retention assembly with perpendicular mounting flange mount to a music stand at a parallel disposition with the ground surface, while also retaining multiple instrument mutes of various sizes and musical-related items in a level, upright disposition. The assembly provides a mute panel defined by mute apertures disposed in a linear, spaced-apart relationship. The mute panel also provides music item apertures disposed in a linear, spaced-apart relationship, and further being parallel to the mute apertures. A mounting flange fixedly attaches to the mute panel in a perpendicular disposition. The mounting flange interfaces with a gapped flange that extends from a sloped support panel of a music stand in slidable or fastenable engagement. Because the mounting flange is perpendicular to the mute panel, the retained mutes and music-related items are maintained parallel with the ground surface, facilitating access to the apertures and retained mutes.

A mute rack with palette shape and multiple retention apertures for retaining wind instrument mutes and music related items in upright position. The mute rack provides a palette-shaped panel defined by an edge, a left region, and a right region. The left and right regions join together at a junction region. The left region forms multiple left apertures, the right region forms multiple right apertures, and the junction region forms a junction aperture, with at least one of the apertures having a different dimension. A clamp bar detachably attaches the panel to a rod, like a music stand. The clamp bar comprises a torque mechanism that is rotatably manipulated to detachably attach to the rod. The clamp bar also comprises a bracket fixedly mated with the edge of the panel. The bracket forms a hole that enables passage of a screw of the torque mechanism for tightening against the rod.

A multi-arm swiveling mute rack provides swiveling arms and annular members that retain instrument mutes in an upright position, allowing each mute to be independently swiveled horizontally up to 360° for selective access to mutes. A base portion mounts to a shaft or flat surface near a musician for supporting mute rack. An axle extends vertically from base portion. A stationary lower plate receives axle, and a lower arm terminating at a lower annular member extends from the lower plate to retain a mute. Multiple rotatable upper plates and their respective upper arms terminating at upper annular members stacked above the lower plate. The upper plates swivel about the axle so that their respective arms and annular members swivel while retaining mutes. The arms are marked to define the relative angle of the mutes to each other. Multiple music item containers at the base portion retain music related items.

Systems and methods for controlling a vehicle steering system are provided. In one exemplary embodiment, the method includes receiving a desired front road wheel angle signal at a controller. The desired front road wheel angle signal is indicative of a desired front road wheel angle of vehicle wheels. The method further includes receiving a parking assist request signal at the controller indicating a parking assist operational mode is desired. The method further includes generating a desired motor torque signal for controlling a power steering motor in the parking assist operational mode utilizing the controller, based on the desired front road wheel angle signal and the parking assist request signal.

A method for detecting a loss of motor control in an electric power steering system is disclosed. In an exemplary embodiment, the method includes determining a duty cycle of a steering command signal generated by a controller. The steering command signal commands a steering mechanism to be turned in either a first or a second direction, the second direction being opposite to the first direction. A steering velocity of the steering mechanism is determined, the steering velocity being characterized by a steering velocity magnitude and a steering velocity direction whenever the steering velocity is greater than zero. The steering velocity direction corresponds to either the first or the second direction. The duty cycle is then compared to a first selected value, and the steering velocity magnitude is compared to a second selected value. If the duty cycle exceeds the first selected value, the steering velocity magnitude exceeds the second selected value, and the steering velocity direction is opposite to the direction commanded by the steering command signal, then a fault signal is generated.

A rotor comprises a first rotor lamination and a second rotor lamination. The first rotor lamination and the second rotor lamination are configured for defining, when joined into rotor assembly, a central axis of rotation and a plurality of interior magnet pockets disposed symmetrically about the central axis of rotation, each pocket of the plurality of interior magnet pockets is configured for housing and retaining a permanent magnet. A method of forming a rotor comprises forming a first rotor lamination and a second rotor lamination, rotating the second rotor lamination about an axis of symmetry of the second rotor lamination; and mating the first rotor lamination to the second rotor lamination such that a first notch of the first rotor lamination is disposed adjacent to the first notch of the second rotor lamination.
