1. A method for reducing excessive motor vehicle roll angle using a feedforward control, comprising the steps of:
determining a steering angle of a vehicle;
determining a speed of the vehicle;
estimating a lateral acceleration of the vehicle based on the steering angle and the speed;
determining a lateral acceleration proportional and derivative (PD) term of the estimated lateral acceleration; and
implementing roll angle reduction when the lateral acceleration PD term exceeds a first threshold.
