Abstract
A vehicle (10) has a camera recognition system to detect and interpret a road sign (14) indicative of a gradient. A gradient related shift map of an automatic vehicle transmission is pre-selected upon recognition of the road sign, and implemented upon detection that the gradient has commenced. The invention provides for rapid and consistent implementation of a suitable shift map on a gradient.
