DRIVING ASSISTANCE METHOD AND DEVICE FOR A VEHICLE FOR TRAVELLING ALONG A PREDETERMINED PATH BETWEEN A FIRST POINT AND A SECOND POINT

摘要

The invention relates to a driving assistance device (100) for a vehicle for travelling along a predetermined path between a first point and a second point. The invention is characterised in that the assistance device includes a generation means for generating a curve of optimal driving parameters for optimising the energy burnt by the vehicle for travelling along said path and the time required for travelling along said path, a means (180) for determining a current driving profile of the vehicle, a means (220) for determining an optimal driving profile for the current position from the optimal profile curve, a comparator (300) for determining a deviation between the current driving profile and the optimal driving profile for the current position, and a means (320) for correcting the driving profile of the vehicle based on the determined deviation (e(t)).
