Method for optimization of power transmission to motor vehicle drive wheels via the gear train using navigational data and predicted vehicle route to optimize engine and gear control to improve fuel consumption and or safety

摘要

Method supplies instantaneous vehicle position and data relating to the route to be followed to a controller (21) for engine and gears. The controller calculates ideal values for engine and gear ratio taking into account the navigational or IPS (intelligent predicative system) data and uses it to optimize driving behavior to save fuel or drive safely around schools etc. The controller (21) has an IPS block (20) in which data is processed with the resulting IPS predictions (50) used in gear train management (60) to generate gear change commands towards a selected driving behavior. Under certain driving conditions certain gear-changes can be prevented.
