Abstract
Disclosed is a method for controlling the powertrain of a motor vehicle between the current location of the vehicle and an arrival point, including calculating a theoretical optimal traction force, determining a friction force applied to the vehicle, calculating an actual optimal force to be applied to the wheels as far as the arrival point, and applying a traction force to the wheels of the vehicle when the calculated actual optimal force is strictly greater than a predetermined threshold value or else not applying a force to the wheels of the vehicle when the calculated actual optimal force is greater than or equal to zero and less than or equal to the predetermined threshold value, or else applying a braking force to the wheels of the vehicle when the calculated actual optimal force is strictly less than zero.
