Abstract

In the last years, energy efficiency has been of great concern due to the increasing number of vehicles that is on the road. For this reason, energy recovery systems are being developed. Regenerative dampers, which are a category of these devices, are able to harvest energy coming from the road irregularities. In this way, the energy is no more dissipated into heat by the damper, but it is recovered through an hydraulic pump rigidly connected to an electric generator. The goal of this study is to develop a Matlab and Carsim full-vehicle model of a segment C car with regenerative hydraulic dampers in order to evaluate the improvements that could be obtained in terms of harvested energy and, also, in terms of vehicle comfort and dynamics by properly tuning the damper device. Moreover, an analysis on the CO2 savings will be carried out, considering several driving conditions, with different road roughness profiles and vehicle velocities.
