Green driver assistance systems

Decreasing the use of energy in transportation is a key goal. The project demonstrates innovative ecodriving support systems adapted to the specific context of PT as well as different types of buses (diesel, gas hybrid, electric) and compliant with IT standards. The demonstrations allow a comparison and evaluation of different approaches to the development of underlying models. They also aim to increase passenger comfort thanks to characteristics of eco-driving - calmer and smoother operation.

A large number of driver assistance systems, including eco-driving systems, already exist for cars and trucks. However they do not take into account the public transport specifics where the driver needs to keep to a set schedule and starts/stops frequently. “After-market” eco-driving systems designed generically for vehicle fleets provide limited access to data other than vehicle accelerations and braking. Thus, they neither take into account several factors which influence energy consumption, nor differences between the driver’s need for feedback in e.g. diesel compared to electric buses. Moreover, in eco-driving, like in other driver assistance systems, the efficiency of the feedback relies on the information transmitted to the driver but also on the design of the human machine interface (HMI). Present interfaces typically include displays showing the driver’s eco-driving performance in terms of basic feedback which may suffice for the experienced driver but not for the less experienced. At the same time too much information will be difficult to perceive and may even distract the driver. EBSF_2 will develop insights into this aspect, focusing on hybrid and electric vehicles, by exploring eco-driving support systems adapted to a public transport context as well as information channels, required contents and appropriate choice of modality to inform drivers as well as enhance drivers’ learning.
