A steering module includes a steering wheel which is provided in front of a driver seat, a column cover which is provided on a vehicle front side of the steering wheel, extends in a forward and rearward direction of a vehicle, and has a functional component mounting region in at least one of an inner inside and an upper portion thereof, and a meter member which is formed integrally with the column cover and includes a main display portion disposed at a position spaced apart from the column cover.

A handwheel actuator for a steer by wire system may include a feedback actuator and a column for operably coupling a handwheel to the handwheel actuator. The column includes a column shaft extending from a first end of the column to a second end of the column. The feedback actuator is operably coupled to the second end of the column and provides tactile feedback to an operator responsive to movement of the handwheel. The feedback actuator includes a torsion bar coaxial with the column shaft. The column shaft is supported relative to a housing of the column by a first column shaft bearing disposed proximate to the first end of the column and a second column shaft bearing disposed proximate to the second end of the column. The torsion bar is operably coupled to a sleeve element that is operably coupled to the column shaft proximate to the second column shaft bearing to facilitate torque transfer between the column shaft and the torsion bar.

Machine-learning-based steering torque non-uniformity compensation for vehicles is enabled. For example, a system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise: a machine learning component that generates a steering non-uniformity model based on machine learning applied to past steering data representative of positions and steering ratios of a steering wheel of a vehicle, and a torque compensation component that, using current position data representative of a current position of the steering wheel and the steering non-uniformity model, determines a torque to apply to the steering wheel configured to offset a steering non-uniformity at the current position.

A steering column assembly comprises an outer jacket extending along an axis and defining a central opening for placing a steering shaft and a bearing assembly. A bearing retainer is located in the outer jacket for axially retaining the bearing assembly in the outer jacket. The bearing retainer comprises a first surface spaced from a second surface by an outer edge and an inner edge. The inner edge defines an opening for placement of the steering shaft. The bearing retainer includes a first spring finger extending from the first surface away from the second surface at an angle and a second spring finger extending from the second surface away from the first surface at an angle.

A steer-by-wire steering device includes a first member, a second member, and a stopper. The first member includes a first base surrounding an input shaft and rotatable, a first protrusion protruding from the first base in a radial direction or in an axial direction, and a first weight provided on the first base so as to make a weighted center consistent with a center of the input shaft. The second member is rotatable together with the first member with the first protrusion being abutting the second protrusion. The stopper is provided on a trajectory of the second protrusion, and is capable of restricting the turn of a steering wheel via the input shaft when abutting with the second protrusion.

A variable mechanical advantage shaft coupling (1), typically used in an electric power assisted steering system, comprising: an input shaft (2); an output shaft (3); and at least one lever (9), each lever comprising: a lever body; a first connection (5) connecting the lever body to a first shaft (2) of the input shaft and the output shaft at a point offset from an axis of rotation of the first shaft so that the lever body can pivot relative to the first shaft; a second connection (11) connecting the lever body to a second (3), different, shaft of the input shaft and the output shaft at a point offset from its axis of rotation so that the lever body can pivot relative to the second shaft; and a fulcrum point about which the lever body can pivot; in which each first connection (5) is able to slide along an axis substantially parallel to the axes of rotation of the first and second shafts (2, 3) along the respective lever body, each lever connecting the input and output shafts (2, 3) with a mechanical advantage that varies dependent upon the position of each sliding connection along the first shaft.

A snowmobile comprises a plurality of ground engaging members, a frame supported by the ground engaging members, and a powertrain assembly supported by the frame. The snowmobile further comprises a rear suspension assembly supported by the frame which includes a plurality of slide rails, at least one linear force element operably coupled to the slide rails, and at least one rear idler wheel operably coupled to the slide rails with a rear shaft. The rear shaft is operably coupled to the slide rails with a single fastener received into one end of the rear shaft.
