Problems solved by technology

However, the algorithm does not account for negative values
Therefore, this algorithm can only be used for internal combustion engine vehicles and cannot be used for electric vehicles with possible energy recovery (eg, with regenerative braking)
Therefore, these methods are not suitable for any type of vehicle

Embodiment Construction

[0040] The invention relates to an economical route planning method, ie a method of determining a route that minimizes the energy consumption of vehicles traveling on a road network. A route is considered to be the path a vehicle should travel to travel from a starting point (the vehicle's current location) to an ending point (the vehicle's destination).

[0041] The method according to the invention is suitable for any type of vehicle: fuel vehicles, hybrid vehicles, electric vehicles.

Abstract

The present invention relates to a method for determining a route (ITI) that minimizes the energy consumption of a vehicle based on a vehicle dynamics model (MOD) that uses a shortest path algorithm (ALG) that is dependent on vehicle speed and acceleration, line graph (GA) construction, and suitable for negative energy.

Description

technical field [0001] The invention relates to the field of vehicle navigation, and in particular to the field of economical routing, which determines a route that minimizes the energy consumption of a vehicle for a given route. Background technique [0002] According to the International Energy Agency, more than 50% of the gasoline consumed in the world is used by the transportation sector, and more than 3 / 4 is used for road traffic. Furthermore, according to the agency, in Europe in 2006 the transport sector was responsible for about a quarter (23.8%) of greenhouse gas emissions and over a quarter (27.9%) of carbon dioxide emissions. [0003] Therefore, improving the energy efficiency of road travel to reduce energy consumption (whether fuel or electricity) is more important than ever. Thus, Advanced Driver Assistance Systems (ADAS) represent a promising solution that is both economical (simply use the driver's smartphone) and non-intrusive (no modifications to the mecha...
