Extended-Kalman-filter-based regenerative and friction blended braking control for electric vehicle equipped with axle motor considering damping and elastic properties of electric powertrain

Because of the damping and elastic properties of an electrified powertrain, the regenerative brake of an electric vehicle (EV) is very different from a conventional friction brake with respect to the system dynamics. The flexibility of an electric drivetrain would have a negative effect on the blended brake control performance. In this study, models of the powertrain system of an electric car equipped with an axle motor are developed. Based on these models, the transfer characteristics of the motor torque in the driveline and its effect on blended braking control performance are analysed. To further enhance a vehicle's brake performance and energy efficiency, blended braking control algorithms with compensation for the powertrain flexibility are proposed using an extended Kalman filter. These algorithms are simulated under normal deceleration braking. The results show that the brake performance and blended braking control accuracy of the vehicle are significantly enhanced by the newly proposed algorithms.

Exploring the hidden potential of sugar beet industry brownfields (case study of the Czech Republic)

The paper focuses on spatial analyses of sugar beet industry brownfields in the Czech Republic. In the first part of the paper history of sugar beet industry on the area of the Czech Republic is briefly presented, then links between location of these sites and its transport potential are discussed. Benefits of brownfields regeneration for regional development are also evaluated. In the empirical part of the paper 49 brownfield sites within the Czech Republic, where the sugar beet industry was abandoned during the transition period after 1989, are evaluated and classified based on field research and aerial picture analyses. Three examples of reuse of former sugar beet factories are finally presented. It was found that development potential of studied sites is highly depended on their geographical location and some inspiration might be derived from presented examples. More targeted supportive policy in the Czech Republic to support regeneration of brownfields is needed. In the concluding part of the paper further development possibilities of sugar beet industry brownfields and their railway connection are considered.
