Regenerative braking technology is essential for reducing energy consumption in electric vehicles (EVs). This study introduces a method for optimizing the distribution of deceleration forces in front-wheel-drive electric vehicles that complies with the distribution range outlined by ECE-R13 braking regulations and aligns with an ideal braking distribution curve. In addition, using a fuzzy control strategy to manage the complex variables of the regenerative braking process, a robust and adaptable system is developed on the Simulink platform. Tested across various driving cycles are NEDC (New European Driving Cycle), WLTC (World Light Duty Vehicle Test Cycle), FTP-72 (Federal Test Procedure 72), and FTP-75 (Federal Test Procedure 75). The method significantly improves energy efficiency: 13% for WLTC, 16% for NEDC, and 30% for both FTP-72 and FTP-75. The simulation results were compared to regenerative braking control techniques A and B, showing that the proposed control method achieves a higher brake energy recovery rate. This leads to a considerable improvement in the vehicle’s energy recovery efficiency. These findings confirm the efficacy of the proposed regenerative brake control system, highlighting its potential to significantly enhance the energy efficiency of electric vehicles.

As a kind of smart damping controllable device, magnetorheological (MR) fluid damper is a hot research topic in the field of vibration control. In this paper, the mechanical properties of MR damper under different temperatures were investigated. A set of test systems, including force sensors, data acquisition platform, stepper motor and K-type temperature sensor was built to test the damping force of MR damper. LabVIEW software was used to compile a data acquisition platform and collect the voltage signals of temperature and pressure sensors, and the data were analyzed by Matlab software. The damping force of the MR damper under different temperatures was obtained. The result shows that, at the range of 20 ~ 40°C, the temperature has a great influence on the MR damper, and the damping force decreases with the increasing of temperature.
