Abstract:
A method of cornering identification for an anti-lock control system in a vehicle with two front wheels and two rear wheels, wherein the rotational behavior of the vehicle wheels is measured by wheel sensors and evaluated to determine a vehicle reference speed which is used as a reference value for ascertaining wheel slip signals and for breaking pressure modulation, and wherein criteria for cornering identification and the direction of cornering are derived from the wheel slip signals, wherein the wheel slip signals are filtered and the filtered signals are compared, and wherein ""cornering"" is identified when simultaneously the filtered wheel slip signals on the two front wheels are in excess of a predetermined front-wheel-related maximum slip value that is responsive to at least one of an instantaneous vehicle speed and vehicle reference speed, and the filtered wheel slip signal of one rear wheel is above a predetermined rear-wheel-related maximum slip value, and the filtered wheel slip of the other rear wheel is below a predetermined rear-wheel-related slip value that is responsive to the vehicle reference speed, and the rear wheel, having at least one of the lower slip value and the higher speed, is assessed as curve-outward rear wheel to determine the direction of cornering.
