Abstract
A system 300 for controlling vibratory motion in a vehicle steering wheel 20 prone to oscillate in a given direction due to extraneous inputs at one or more frequencies. The system 300 has a steering wheel 20 of the type exhibiting a vibratory motion along a defined axis at one or more frequencies, at least one sensor for sensing the acceleration of the steering wheel 20 along the defined axis and an active control mechanism responsive to the output of the at least one sensor. The sensor is an accelerometer having a movable first mass 70 and a solenoid coil 56 which when activated moves the mass 70 in a direction opposite to the motion of the steering wheel 20 and at the frequency of motion of the steering wheel 20.
