“…In [49], the conditions of EV safety tests are analyzed in terms of protecting people inside the vehicle in frontal, side, and rear collisions, and specific aspects for such vehicles in the electrical aspect are indicated. Similar issues are considered in [50][51][52]. The work [53] also paid attention not only to the technical side of crash tests for EV assessments but also to the safety of employees and research infrastructure, proposing a set of appropriate procedures for this purpose.…”

The electrification of road transport is developing dynamically around the world. Many automotive companies are introducing electric vehicles to the market, and their popularity is constantly growing. The increasing popularity of electric vehicles is caused by individual countries’ governments encouraging people to switch to electric vehicles and their lower operating costs. In 2022, the number of electric vehicles in China will exceed 10 million. Europe and the USA rank second and third in global electric car stock, respectively. The number of available electric vehicle models is constantly growing, remaining approximately 2.5 times smaller than the case of vehicles with an internal combustion engine. Among others, a significant limitation to the popularity of electric cars is users’ fear of range and the density of the charging infrastructure network. This paper presents the objectives regarding public areas and charging stations around the European Union’s comprehensive and core transport network. It is worth noting that the vehicle and charging point’s charging connectors vary depending on the geographical region. Therefore, the currently used charging connectors for different regions are presented. Charging time depends significantly on the charging current, the power of the charging point, and the devices installed in the vehicle. The paper analyzes the limitations of charging power resulting from the onboard charger’s power and the charging point’s power. It presents the charging time of selected electric vehicles. The second aspect that is also the subject of user concerns and discussed in this article is issues related to the safety of electric vehicles. General safety indicators of such vehicles based on Euro-NCAP tests are characterized. Attention was also paid to more detailed problems related to active and passive safety and functional safety analyses. The issue of the fire hazard of electric vehicles was discussed together with modern experiences regarding post-accident procedures in the event of fires.

Adaptive Cruise Control (ACC) is one of Advanced Driver Assistance Systems (ADAS) which takes over vehicle longitudinal control under necessary driving scenarios. Vehicle in ACC mode automatically adjusts speed to follow the preceding vehicle based on evaluation of the surrounding traffic. ACC reduces drivers’ workload as well as improves driving safety, energy economy, and traffic flow. This article provides a comprehensive review of the researches on ACC. Firstly, an overview of ACC controller and applied control theories are introduced. Their principles and performances are discussed. Secondly, several application cases of ACC control algorithms are presented. Then validation work including simulation, Hardware-in-the-Loop (HiL) test and on-road experiment is descripted to provide ideas for testing ACC systems for different aims and fidelities. In addition, studies on human-machine interaction are also summarized in this review to provide insights on development of ACC from the perspective of users. At last, challenges and potential directions in this field is discussed, including consideration of vehicle dynamics properties, contradiction between algorithm performance and computation as well as integration of ACC to other intelligent functions on vehicles.

“…MPC is able to balance different performance indicators and incorporate constraints effectively within a cost function. A study showed that MPC consumes 5% less fuel when compared with LQR during road tests [3]. In addition, based on online optimization of the cost function in every time step, MPC is much more robust against disturbances such as rapid traffic condition changes like the cut-in of another vehicle when compared with LQR.…”

One of the Advanced Driver Assistance Systems (ADAS), Adaptive Cruise Control (ACC), takes over longitudinal control of the car when activated. This article analyses a simplified Adaptive Cruise Control (ACC) function using Model Predictive Control (MPC). The aim is to ensure the desired distance between a preceding target vehicle moving with constant velocity and the following host vehicle. Inputs and state variables are constrained for drivability and safety concerns. The simulations performed using MATLAB under various initial conditions validated the MPC design. The optimal selection of the prediction horizon and the effectiveness of introducing constraints are also discussed in this paper.
