“…[44,214] The MREs bush shown in Figure 19, patented by Watson in 1997, is a novel technique for tuning the stiffness constant, which allows for increasing passenger satisfaction as a result of a decrement in the dissatisfaction associated with braking noise, vibration, and harshness. [33,161,215] The placement of the MRE bush in the longitudinal suspension link is mainly proposed for overcoming disturbance in a longitudinal direction. The state of MREs bush stiffness depends on the electrical current supplied by the power regulator as a function of the output signal from the control unit.…”
