Sliding-Mode ABS Wheel-Slip Control

Sliding-mode control is applied to ABS wheel-slip control due to the nonlinearity of vehicle traction system. Vehicle traction dynamics are reviewed. Sliding-mode application to ABS wheel-slip control is discussed. An experimental setup in a brake test cell with an electric dynamometer is used to emulate the ABS braking of a half car. Test results for the sliding-mode ABS wheel-slip control indicate that sliding-mode ABS control provides tight wheel-slip control on both dry and ice-like surfaces.
