Summary: This study investigated the charging behavior of plug-in hybrid electric vehicles (PHEV) and found that most users do not charge their vehicles overnight and engage in additional charging on 20-26% of driving days. The study also indicated that the utility factor should not be the sole measure of PHEV environmental performance.

Summary: This paper proposes a real-time predictive energy management strategy for plug-in hybrid electric vehicles, which coordinates fuel economy and battery lifetime through velocity prediction and SOC reference generator, formulates a model predictive control problem for cost minimization, and utilizes the C/GMRES algorithm to handle real-time optimization of engine power command. Numerical simulations demonstrate the effectiveness of this strategy in minimizing fuel consumption and restricting battery aging, showing superior solving quality and real-time applicability compared to other algorithms.

Summary: The study investigated the daily charging behavior of over 10,000 Chevrolet Volt PHEVs and found that a percentage of users do not charge overnight, while additional charging occurs on 20-26% of driving days. It also concluded that the utility factor should not be the sole measure of environmental performance for PHEVs.

Summary: We have developed an event-driven Receding Horizon Control scheme for a Mobility-on-Demand System in a transportation network, which reduces the complexity of the vehicle assignment problem and enables real-time implementation. Simulation results demonstrate the effectiveness of the RH controller in terms of real-time implementation and performance compared to known greedy heuristics.

Summary: Plug-in hybrid electric vehicles (PHEVs) are considered favorable transitional technology for road transport electrification. However, recent studies challenge their effectiveness in reducing CO2 emissions in real-world conditions. This study tested four Euro 6 PHEVs and found that their in-use CO2 emissions can range from 0 to 6 times the official type-approval CO2 value. A three-dimensional CO2 emissions model is proposed based on charge level and average trip speed or wheel energy. The study concludes that, although real-world emissions of PHEVs may increase compared to official values, they still generally remain lower than conventional powertrains.

Summary: This paper presents a wayset-based guidance method for a fully-actuated multirotor aerial vehicle with fixed or vectorable rotors. A hierarchical guidance and control framework with two nested loops is proposed to tackle the problem. The outer loop adopts a guidance strategy based on the nonlinear model predictive control paradigm, while the inner loop uses a single multi-variable inverse-dynamic force-torque control law and an optimal control allocator formulated through a convex program. The stability of the loops, the feasibility of the guidance algorithm, and the control allocation are proven. Numerical simulations with a quadrotor equipped with two-degree-of-freedom vectorable rotors demonstrate the effectiveness of the proposed method in guiding the vehicle while respecting rotor constraints.

Summary: This paper proposes a reactive, safe, and high-performance distributed constrained control law for ensuring safety in multi-UAV systems. The control law is ideally suited for systems with limited on-board hardware for computation and communication. The safety, efficacy, performance, and scalability of the method are demonstrated and benchmarked against state-of-the-art real-time collision avoidance methods by simulations and field experiments with multiple quadrotor UAVs.

Summary: This paper proposes a stereo vision-aided receding horizon vehicle dynamic control system for independent drive vehicles steered by wire. The system calculates and updates control inputs to minimize a cost function, allowing it to track the desired slip angle and yaw rate of a dynamic vehicle. By combining stereo vision with existing sensors, the system improves state estimation accuracy in noisy environments and enhances tracking performance on slippery or more severe roads.
