<div>This article presents the design and the analysis of a control logic capable of optimizing vehicle’s energy consumption during a braking maneuver. The idea arose with the purpose of enhancing regeneration and health management in electric vehicles with electro-actuated brakes. Regenerative braking improves energy efficiency and allows a considerable reduction in secondary emissions, but its efficiency is strongly dependent on the state of charge (SoC) of the battery. In the analyzed case, a vehicle equipped with four in-wheel motors (one for each wheel), four electro-actuated brakes, and a battery was considered.</div> <div>The proposed control system can manage and optimize electrical and energy exchanges between the driveline’s components according to the working conditions, monitoring parameters such as SoC of the battery, brake temperature, battery temperature, motor temperature, and acts to optimize the total energy consumption. The solution devised allows first to maximize the effects of regenerative braking when the battery SoC is too high to regenerate efficiently, then to safeguard the condition of the battery for both the battery’s long life and overheating and safeguard the condition of the brakes to prevent their overheating.</div>

<div class="section abstract"><div class="htmlview paragraph">This paper presents the analysis of an innovative braking system as an alternative and environmentally friendly solution to traditional automotive friction brakes. The idea arose from the need to eliminate emissions from the braking system of an electric vehicle: traditional brakes, in fact, produce dust emissions due to the wear of the pads. The innovative solution, called Zero-Emissions Driving System (ZEDS), is a system composed of an electric motor (in-wheel motor) and an innovative brake. The latter has a geometry such that it houses MagnetoRheological Fluid (MRF) inside it, which can change its viscous properties according to the magnetic field passing through it. It is thus an electro-actuated brake, capable of generating a magnetic field passing through the fluid and developing braking torque.</div><div class="htmlview paragraph">A performance analysis obtained by a simulation model built on Matlab Simulink is proposed. The model is able to simulate the transient 1D motion of an electric vehicle equipped with four wheels, each having a ZEDS mounted. It has the ability to simulate a road test, supervise the behavior of the vehicle, monitoring parameters such as the State of charge (SoC) of the battery, the current used by the vehicle's battery, speed, drive torque and the decoupling between the regenerative braking torque and the Magneto-Rheological brakes torque.</div><div class="htmlview paragraph">The primary goal of the model is to verify the capability of the braking system to develop a sufficiently high torque to satisfy safety standards and regulation requests. The study creates also a starting point for thermal analysis of the system.</div></div>
