An overview of driver feedback systems for efficiency and safety

Driver feedback systems have the potential to improve driving safety and efficiency by providing instructions to drivers aimed at improving their driving style. There is already a rich body of available literature devoted to the derivation of energy efficient speed profiles to develop driver feedback or eco-driving systems. While most of them can be applied to any type of vehicle, their effectiveness will be maximized if their formulation involves the dynamics of the particular vehicle powertrain configuration. This paper summarizes the research trends in the development of these systems that have been reported in the literature to date classifying them according to the powertrain structure and the nature of the control strategy. The study concludes with a discussion on the remaining challenges and potential future research directions.
