An bluetooth audio steering wheel knob is quickly attachable and detachable without tools and includes a bluetooth circuit and at least one audio transducer. The bluetooth audio steering wheel knob includes a housing having a shaft inserted into a bracket mounted to a steering wheel. The shaft may include a spring loaded ball detent which engages a recess ring inside a shaft passage in the bracket, allowing the bluetooth audio steering wheel knob to be detached by a firm tug, or a mounting block may include a spring loaded lock which engages a stud extending down from a housing base. The batteries, a bluetooth circuit and at least one audio transducer is housed inside the bluetooth audio steering wheel knob and is rechargeable using a plug in charger or separate base.

In steering members of a steering device, a shift-up switch and a shift-down switch for upshifting or downshifting with respect to a transmission are provided to respective inner sides in a vehicle width direction of truncated square pyramidal parts at upper end portions of grip parts. On-off switches for switching between a plurality of vehicle behavior controls are provided to respective front sides of the truncated square pyramidal parts. A characteristic amount addition switch and a characteristic amount subtraction switch respectively for increase and decrease a characteristic amount of a vehicle behavior control are disposed respectively at bottoms of concave portions formed on rear sides or outer sides in the vehicle width direction on the truncated square pyramidal parts.

A system for grip-based handwheel compensation includes a net handwheel torque moment determination module that determines a net handwheel torque moment between a left grip and a right grip on a handwheel. The system also includes a filter transition compensation module that applies a filter to smooth transitions in the net handwheel torque moment as a bias compensation. The system further includes a handwheel torque compensation module that determines a grip compensated handwheel torque based on a difference between a sensed handwheel torque and the bias compensation.

According to the disclosure, the steering control device and method may enhance the driver's steering feeling by correcting the steering torque due to a difference in linear distance despite a difference in the linear distance from the rotation axis according to the position of the pressure applied to the steering wheel shaped so that the linear distance from the rotation axis increases/decreases.

A steering control assembly including: a base configured to couple with a steering shaft; a ring mounted to the base and configured to rotate independent of the base; a locking member movable between a locked configuration and an unlocked configuration, in the locked configuration the locking member locks the ring to the base to restrict rotation of the ring independent of the base, and in the unlocked configuration the ring is free to rotate independent of the base; and a handle mounted to the ring and rotatable with the ring independent of the base when the locking member is in the unlocked configuration to adjust a radial position of the handle relative to the base, the handle configured to be grasped by a user to rotate the steering control assembly and the steering shaft when the locking member is in the locked configuration.

The invention provides, in one aspect, a multifunctional operating device for operating a motor vehicle. The operating device includes a handle and an operating head fixed to the handle. The operating head includes a head housing, a circuit board with at least one switch element, and a support part, mounted inside the head housing, upon which the circuit board is mounted. The switch element is configured to emit an acoustic response when actuated. The head housing is formed as a resonance body for amplifying the acoustic response.

Handle consisting of a gripping knob internally provided with a housing cavity in a stable position of a pin, the pin consisting of at least a portion with a larger-diameter section and of a portion with a smaller diameter projecting therefrom. At the top end of the smaller-diameter portion, a retaining member is provided, having a larger diameter with respect to that of the smaller-diameter portion. An elastic bush is housed on the smaller-diameter portion for engagement with the inner surface of the knob. Between the retaining member and the elastic bush, a washer is arranged of a material aimed at minimizing friction.
