A system and method for computationally estimating a tire normal force for use in vehicle antilock braking, adaptive cruise control, and traction and stability control by correcting measured accelerations with respect to the estimated road angles. The system and method are operative to measure an acceleration at three points on a sprung mass of the vehicle and estimate a tire normal force of a tire in response to the three acceleration measurements as an input to the vehicle controller.
