Abstract
A vehicle carried profile generator generates a speed profile to control a vehicle governor at the transition from a higher to lower speed limit. The speed profile is calculated and checked to ensure it starts at a valid speed limit, continually decreases and is above a wayside speed limit. The governor is modified or controlled to inhibit brake application or a requirement for a brake application so long as actual speed is below profile speed.
