Method for estimating the energy consumption of a motor vehicle
First Claim
1. A method for estimating energy consumption of a motor vehicle over a given route, comprising:
- (a) splitting the route into route portions;
(b) allocating a plurality of set speeds to each route portion, as a function of at least one characteristic of the route portion;
(c) estimating, via processing circuitry of a navigation system and for each route portion, a speed profile as a function of at least one characteristic of a driving style of a driver of the motor vehicle and the plurality of set speeds of the route portion, to establish for each route portion an estimate of each speed profile as a function of time, the speed profile being generated via a combination of a plurality of autoregressive-moving-average models (ARMA), wherein each ARMA model of the plurality of ARMA models includes the at least one characteristic of a driving style of a driver of the motor and a respective different set speed of the plurality of speeds;
(d) estimating the energy consumption of the vehicle over the given route, as a function of an average of the estimate of the speed profiles;
(e) calculating a range of the motor vehicle over the given route based on the estimated energy consumption; and
(f) communicating, via the navigation system, the range of the motor vehicle.

Abstract
A method for estimating energy consumption of a motor vehicle during a given journey, including: a) cutting the journey into portions of journey, b) allocating a setpoint speed to each portion of journey, as a function of at least one characteristic of the portion, c) estimating, for each portion of journey, an evolution of speed of the vehicle as a function of time, the speed being estimated as a function of at least one characteristic of the portion of journey and as a function of a predetermined driving behavior associated with the setpoint speed of the portion, to establish for a whole of the journey an estimation of the evolution of the speed of the vehicle as a function of time, d) estimating the energy consumption of the vehicle during the journey, as a function of the evolution of the estimated speed.
