The application of an active control, such as four-wheel steering and active suspension, to cars has changed not only the vehicle dynamics design but also the dynamic characteristics of cars. Active four-wheel steering reduces the sideslip angles of the wheels, thus the unnecessary yawing motion of cars decreases and the time lag in the dynamic response to handling also decreases. An active roll control of the car body makes use of type properties to the best advantage. The four-wheel steering and active suspension upgrade the dynamic performance of cars, and expand the limit performance of dynamics. An adaptive control, integrated control and intelligent control will be introduced to cars, completely changing vehicle dynamics of cars in the near future.

Natural joints exhibiting excellent performance under reciprocating slow speed and high loading conditions have a prominent lubrication mechanism as an adaptive multimode lubrieation, where elastohydrodynamic fluid film plays the main role supported by various supplimental lubrication mechanisms. In contrast, most of the existing joint prostheses operate not under fluid film but under mixed lubrication, which induces some tribological problems such as loosening and wear. Thus, recent investigations on the lubrication mechanisms in natural synovial joints and total replacement joints are reviewed, and then subjects on lubrication and wear in joint prostheses and optimum design of joint prostheses with artifieial cartilage are discussed.
