Abstract
A method and system, for use with a vehicle including a pair of front wheels, a pair of rear wheels, and an anti-lock brake system (ABS), for detecting when the vehicle is executing a turning maneuver. The system includes means for performing the method steps of determining a speed difference between one pair of the vehicle wheels, determining the deceleration of each of the one pair of vehicle wheels, comparing the speed difference to a turning detection threshold, comparing the decelerations to a deceleration threshold, and detecting a turning maneuver based on those comparisons.

A method for use with a vehicle including a pair of front wheels, a pair of rear wheels, and an anti-lock brake system (ABS), the method for detecting when the vehicle is executing a turning maneuver, the method comprising:
- determining a speed difference between one pair of the vehicle wheels;
- determining the deceleration of each wheel of the one pair of vehicle wheels whose speed was utilized to determine the speed difference;
- comparing the speed difference to a turning detection threshold;
- comparing the decelerations to a deceleration threshold;
- and
- detecting a turning maneuver based on the comparison of the speed difference to the turning detection threshold and the decelerations to the deceleration threshold.
