Vehicle sideslip angle, defined as the angle between the longitudinal axis of a vehicle and its velocity vector, is a crucial parameter in vehicle dynamics. Unfortunately vehicle sideslip angle is very hard to access directly, therefore a variety of estimation methods have been developed so far. Such estimation methods are essentially based on model-based approaches or neural networks. This paper looks at the problem from a fresh angle, by investigating possible solutions to measure vehicle sideslip angle via computer vision techniques, harnessing recent improvements in computer vision algorithms. Preliminary experiments on a radio-controlled scaled vehicle show promising results using the "phase correlation" algorithm.

As for current datasets of vehicle 3D points cloud, there are some shortcomings like lack of large vehicles, sparseness of point cloud data and insufficiency of vehicle parts information. In this paper, a high-density points cloud dataset of large vehicles named ZPVehicles(Points cloud of vehicles by Zhejiang Institute of Metrology) is provided. The original data of ZPVehicles is collected by a LAMIoVP(Lidar-based Automatic Measuring Instrument of Vehicle Profile), which is developed by us and installed in a vehicle testing station in Hangzhou, China. ZPVehicles contains the high-density point cloud data of about 800vehicles, which consist of 11 vehicle types such as van, barn truck, fence truck, crane truck, semitrailer tractor, bus, mini-bus, garbage truck, watering truck, communication warehouse truck and fuel tank truck. At the same time, ZPVehicles also provides the standard profile size of each vehicle and every part of the vehicle is labeled. To prove the practicability of ZPVehicles, some usages have been verified and demonstrated by experiments.

This paper presents an automated measurement setup for the electro-mechanical characterization of piezoelectric energy harvesters in cantilever configuration. The setup provides a mechanical stimulus to the harvester and concurrently acquires mechanical and electrical quantities to characterize the electro-mechanical properties of the device under test in open-circuit conditions. The setup, composed by an electrodynamic shaker, a waveform analyzer, and two laser-based positioning sensors, is fully controlled via MATLAB. The use of two laser heads allows to measure the movement of the base, so to automatically consider artefacts due to the non-ideal response of the electrodynamic shaker. The proposed measurement system is compatible with any generic piezoelectric-cantilever harvesters, and it can be exploited for advanced modelling techniques that requires extensive experimental data. The proposed measurement setup was validated through the characterization of a commercial Piezo Protection Advantage (PPA) transducer up to 300 Hz.

As EU countries approved the 2035 phaseout of CO2-emitting cars, electric vehicle technology is going to be predominant for passenger cars. More and more electric vehicle supply equipment will be installed across the countries and, as they are measurement instruments, they will need to be metrologically verified periodically. This paper deals with the realization and testing of field equipment for metrological verification of the metering subsystem inside electric vehicle supply equipment. The test equipment has been realized and tested at the University of Campania "Luigi Vanvitelli" (Aversa, Italy), and it has been used to accurately estimate the energy absorbed by a battery electric vehicle during some recharge sessions.

Nowadays, Remaining Useful Life (RUL) is becoming an important and critical parameter in RAMS (Reliability, Availability, Maintainability and Safety) engineering. In the prognostic research field, much attention is usually given to mechanical device which are characterized by rapid aging processes. However, it is also fundamental to study prognostic and health management of electric and electronic equipment. In this context, electrolytic capacitors have a critical role in reliability of power electronics. Thus, in this work, an exponential degradation model has been used in order to implement a remaining useful life prediction technique for capacitors. A publicly available prognostic dataset composed by six capacitors tested under accelerated conditions has been taken into account. The procedure has been implemented using five capacitors for training and the remaining one for validation. The results of the implemented algorithm allow to estimate with a great advance when the capacitor under test will reach a predetermined failure threshold.

Due to the development of new radar technology for advanced driver-assistance systems (ADAS) and automated driving (AD) applications, testing radars for real world conditions is highly desirable. However, testing autonomous driving functions on public roads can be dangerous and the tests results are not always reproducible. In this paper, we present a novel Over-the-Air (OTA) Hardware-In-the-Loop (HIL) radar target simulator for testing radar systems. The complete simulation setup including hardware and software implementations will be presented in this article. We illustrate a test procedure by creating Euro NCAP scenarios, and explain the benefits and importance of realtime HIL testing of automotive radars.

This paper describes an integrated co-simulation framework of circuital/behavioural/algorithmic type devoted to the design, simulation, and support to validation of a system of measurement based on electrochemical impedance spectroscopy (EIS) for lithium-ion battery cells. The simulation framework comprises two main parts: a circuital simulator and a numerical environment. It allows the study of a generic system: in particular, it has been applied to analyze an EIS system as a whole without neglecting the effects of the hardware nonidealities on the software algorithm (through a direct connection between the circuital simulator and the numerical environment). A model is implemented inside the circuital simulator, replicating as accurately as possible an existing laboratory prototype devoted to EIS measurements. After the simulation of the prototype, the numerical environment executes an algorithmic elaboration to estimate impedance values for a lithium-ion battery. Throughout several simulations, it is possible to check the non-idealities of the prototype. The simulation framework identified and corrected a malfunction of the prototype available in the laboratory and thus permitted the implementation of a circuit with improved performance.

With the rapid development of economy in China, the number of tunnel construction projects is increasing rapidly, and the tunnel safety issues are becoming more and more important, especially some tunnels with large traffic flow. Due to the relatively large traffic flow, unclear vision and narrow space, these tunnels are prone to traffic accidents. According to the statistics of China's traffic police department, the accidents caused by vehicle over-speeding account for a large proportion of many tunnel traffic accidents. Therefore, it is urgent to solve the problem of tunnel over-speeding and ensure tunnel safety. However, the traditional speed measurement method (for example the Doppler-radar based speed meter) is not applicable to the tunnel traffic. In order to make up for this defect, the project aims to develop a dual-infrared laser as a sensor to directly measure the instantaneous speed of vehicles in the tunnel through the time difference triggered by the infrared laser and the fixed distance. In this study, the experimental verification of the dual-infrared laser instrument was carried out in the open road section and in the tunnel. The experimental results show that, in the tunnel, the dual-infrared laser based speed meter can successfully detect the instantaneous speed of vehicles, and the error range meets the metrological verification requirements of China. The research results can help relevant traffic departments to monitor the speed of the tunnel, thus reducing the incidence of traffic accidents in the tunnel, and can also play a powerful deterrent role, making drivers dare not violate the rules at will, so as to facilitate the safe operation and management of the tunnel.

This paper considers the estimation of the state-of-charge of rechargeable batteries based on a classifier trained using two methods. One method uses the values of the parameters in an equivalent circuit model, identified using a frequency-domain approach. The other method is based on a mathematical approximation of the battery voltage time-response to a given 3 s current signal. Classification resorts to a linear discriminant analysis classifier trained both by experimental data and by data obtained through augmentation methods. It is shown that the time-domain based classifier may achieve better performance in terms of probability of correct state-of-charge classification, using experiments of significant less duration than those associated with the usage of the frequency-domain experiments.
