Abstract
In order to imprive the accuracy of the time derivative of a steering angle signal consisting of discrete measured values, a vehicle steering control system for producing a steering angle control signal from the steering angle, the time derivative of the steering angle and other data is provided with a controller having a averaging section for periodically determining an average of a predetermined number of the measured values of the steering angle, and a differentiating section for determining the time derivative of the steering angle by using the averages determined by the averaging section, instead of directly using the steering angle signal.
