A system for measuring motion of a locomotive vehicle includes a speed sensor, a decelerometer and an onboard processing unit. The speed sensor is configured to measure wheel speed of the locomotive vehicle. The decelerometer includes a level-sensitive device configured to measure acceleration or deceleration of the locomotive vehicle as a function of a tilt from a level position. The onboard processing unit computes a current grade traversed by the locomotive vehicle prior to detection of a slip or slide condition based on a first measurement signal from the decelerometer. Upon detection of the slip or slide condition, the onboard processing unit obtains a second measurement signal from the decelerometer and filters out the current grade from the second measurement signal. The onboard processing unit determines an actual acceleration or deceleration of the locomotive vehicle during the slip or slide condition from the filtered second measurement signal from the decelerometer.

A stability control system of a vehicle utilizing an electronic control unit that detects a yaw condition while each of the wheel brakes are actuated by EBCM and the wheel speeds are zero. An electronic control unit includes an electronic braking control module that controls actuation and de-actuation of vehicle brakes on an inclined surface. A yaw condition is identified while all vehicle brakes are actuated on the inclined surface and each wheel speed is zero. The electronic control unit identifies which uphill wheel is leading a direction of the yaw and identifies a wheel of an opposing axle diagonal to the identified uphill wheel. The electronic control unit in cooperation with the electronic braking control module de-actuates the vehicle brakes of the identified uphill wheel and diagonal wheel to increase a side friction to the identified diagonal wheels to reduce further yawing of the vehicle.
