Abstract
In a transportation vehicle control system, a signal is detected from a transposed cable to determine the vehicle position relative to a predetermined speed control zone. This position data, along with other manual and/or automatic inputs, is fed into a profile function generator whose output is a predetermined singular function of the position and other inputs. While the vehicle is within the speed control zone, the output of the profile function generator is converted from digital form into analog form and then used to limit the vehicle speed.
