Driving Assistance Method and Device for a Vehicle for Travelling Along a Predetermined Path Between a First Point and a Second Point
First Claim
1. A method of assisting the driving of a vehicle for traveling along a run defined between a first point and a second point, wherein there is provided a curve of optimum driving profiles seeking to optimize the energy consumed by the vehicle in order to travel along the run and the time taken to travel along the run, in which method, while the vehicle is traveling, the following steps are performed:
- determining a current driving profile at a current position of the vehicle;
determining an optimum driving profile for the current position from the curve of optimum profiles;
determining a difference between the current driving profile and the optimum driving profile for the current position; and
correcting the driving profile of the vehicle as a function of the difference as determined.

Abstract
The invention relates to a driving assistance device (100) for a vehicle that is to travel along a defined run between a first point and a second point. The invention is characterized by the fact that the assistance device comprises generator means for generating a curve of optimum driving profiles seeking to optimize the energy consumed by the vehicle in order to travel along the run and to optimize the time taken to travel along the run, means (180) for determining a current driving profile at a current position of the vehicle, means (220) for determining an optimum driving profile for the current position from the curve of optimum profiles, a comparator (300) for determining a difference between the current driving profile and the optimum driving profile for the current position, and means (320) for correcting the driving profile of the vehicle as a function of the difference (εt)) as determined.
