Advances and Challenges in BBW AWB Dispulsion for Future Automotive Vehicles 2001-01-3321

Current implementation of novel advanced electromechanically (E-M) activated brake-by-wire (BBW) all-wheel-driveable (AWB) dispulsion mechatronic control hyposystems may be comparatively costly. Though, as the cost of macroelectronic commutator (macrocom-mutator) and microelectronic processor (microprocessor) based controllers becomes increasingly cheap, fixed with bettered short-stroke linear brake-force-actuator motors, novel advanced E-M-activated BBW AWB dispulsion mechatronic control hyposystems become a potential practical choice in the not-too-distant future. The size and mass of these short-stroke tubular linear DC-AC macrocommutator brake-force-actuator E-M motors may be comparatively small and light, respectively, in the nearest future with bettered interior permanent magnet (IPM) materials. Specific advantages of the novel advanced E-M-activated BBW AWB dispulsion mechatronic control hyposystem are cleanliness, lack of fluid and flexibility.
This paper presents a very advanced anti-lock and/or anti-spin BBW AWB dispulsion mechatronic control hyposystem with E-M-activated friction disc, ring and/or drum brakes for controlling not only the braking forces during normal riding and cornering but also the braking forces between the inner and outer motorized and/or generatorized wheels (M&GW) in a hard turn independently.
