Abstract
A variable effort power steering unit under control of a microcomputer is able to change steering effort in response to control current. The current is developed as a function of average vehicle speed. In the case of vehicle deceleration, a long averaging time is used to inhibit rapid steering effort changes during braking. In the case of vehicle acceleration, a short averaging time is used for rapid response of steering effort to speed increases.
