On-board System Design to Optimise Energy Management

This paper presents the design of a new onboard system that contributes to the reduction of fuel consumption and CO2 production by optimising vehicle energy. We designed an appropriate instrument that enables the driver to adopt the best driving behaviour, smooth speed and good gear management. A global optimisation algorithm was developed to provide the driver with an economic driving pattern. This algorithm enables the reduction of fuel consumption by 10-15%, depending on the type of vehicle and on driving behaviour. An interaction control system was developed to provide the driver with visual information (optimal speed and gear instructions) and vocal messages with respect to road context in order to reduce risk and human errors.
