MOTOR VEHICLE DRIVING ASSISTANCE METHOD WITH A VIEW TO OPTIMIZING THE USE OF THE POWER SUPPLY

摘要

The invention relates to a motor vehicle driving assistance method comprising at least one electric motor (4) powered by a battery (2) and capable of driving the drive wheels of the vehicle, wherein the method involves calculating an optimized consumption (Creal-Cexcès) for the vehicle from the actual power consumption (UI) of the vehicle and from values collected by sensors of the vehicle (Pchauff, Pclim, N, Text, br), over the same path that the vehicle is in the process of traveling, the optimized consumption corresponding to a reference driving style, and informing the driver of the distance (D) that he/she could travel using the power supply (Wdisp) available on-board the vehicle if he/she were to adopt the reference driving style, or else the driver is informed of the energy savings per unit of distance traveled that he/she might obtain if the reference driving style were adopted.
