Tri-Mode Hybrid SBW AWS Diversion Mechatronic Control for Future Automotive Vehicles

An automotive vehicle steering is achieved not only by means of hand steering wheel (SW) but also by varying actual valued of the angular velocity and sense of rotation of all the electromechanical/mechanoelectrical (E-M/M-E) steered, motorized and/or generatorized wheels (SM&GW) for all-wheel driven (AWD) × all-wheel steered (AWS) automotive vehicles. The betterment tri-mode hybrid steer-by-wire (SBW) AWS diversion automotive high-tech has made significant progress during the 1990s. An evolutionary factor behind this has been the increasing requirements or an active safety as well as ride comfort and handling (RC&H) of automotive vehicles. A major contribution to this progress is the introduction and fast growing application rate of electrically powered and mechatronically controlled rack-and-pinion (R&P) steering gears.
