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 include s a generation means for generating a curve of optimal driving parameters fo r 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 dete rmining a current driving profile of the vehicle, a means (220) for determin ing an optimal driving profile for the current position from the optimal pro file curve, a comparator (300) for determining a deviation between the curre nt driving profile and the optimal driving profile for the current position, and a means (320) for correcting the driving profile of the vehicle based o n the determined deviation (.epsilon.(t)).
