Secondly, a braking energy recovery maximally control strategy is proposed, which assigns the maximum braking force to motor within the ECE regulation, and the other three control strategies that braking force is distributed as Belt line, I line and having no limit is given to comparative analysis. And then, according to the parameters of vehicle and braking system, the FWD and RWD vehicle model and the control strategies mentioned above are built by the cosimulation based on MATLAB/Simulink and CRUISE to analyze the braking energy recovery rate in each braking process of different braking intensities, and the energy-saving rate in five types of running cycle. At last, by the comparative analysis of simulation, it can be acquired that the effect of braking energy recovery in FWD is better than RWD, and the braking energy recovery maximally control strategy proposed is effective which is the nearest to the maximum potential of braking energy recovery.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127481475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hidden object inside the cloak realizes the possibility of communicate with the outside world while maintaining a good invisibility performance without “anti-object”. In particular, this design has different semi-axis (the outer and inner boundary has different shape) so that it is more flexible for different shape object.

It becomes more and more urgent to solve the problem when ADAS or driverless cars goes into application gradually since the positions of cars are essential parameters for the algorithms of autonomous driving and safe driving in tunnels, where video and radar system of cars may encounter problems caused by weak light, obscured sight and strong reflected radar wave. As a solution to this problem, a high precision positioning system with IEEE 802.15.4-2011 UWB as air-interface was designed and implemented. Based on Decwave’s UWB chip, the system can provide centimeter level positioning precision. However, when utilizing the UWB chip in the tunnel positioning system, efficient solutions have to be found to overcome the limitation of the chip’s transmitting range in a scenario of long tunnel, and to enlarge the system capacity which might decrease seriously as the demand of high positioning rate in a scenario of vehicles with high speed. On the other hand, tunnels are prone to traffic accidents while there is usually lack of surveillance system in tunnels located in remote areas. Aiming at this application, the presented system also implements a functionality of accident detection. System overview, related design issues, key technologies and test results are presented in this paper.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127239026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phase shifting element supporting circular polarization is first designed and investigated. Under the control of the driving voltage, the reflection phase of the array element can be switched between 0 and 180 degrees with the change of the LC molecules’ state. Consequently, a circularly polarized beam scanning reflectarray is realized by the phase shifting elements periodically arranged on a plane and illuminated by a feeding horn antenna. Numerical simulations are conducted to demonstrate the reflectarray antenna’s performance. Results show that, with the one-bit phase shifting resolution, the antenna achieves the beam scanning range from -30 degrees to -10 degrees while the gain reaches up to more than 20 dB and the axial ratio keeps less than 3 dB.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127256772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of antenna element structure is based on the common aperture-coupled antennas. To improve the impedance bandwidth, some metalized via holes are introduced surrounded the feeding lines. To improve the isolation and reduce the cross polarization, two-layered power divider networks are optimized and antiphase technique is introduced. Furthermore, array weighting is used to control the side-lobe level of the antenna. The simulated results indicate that an impedance bandwidth of 1.5 GHz with VSWR less than 1.5 can be realized.

Therefore, it is very important to detect and recognize this phenomenon. In recent years, coherent Lidar has been proposed to detect low-level wind shear, but the common recognition methods need large computation to inverse the wind field to recognize the type. In this paper, compressive sensing (CS) is put forward to quickly sample and reconstruct wind field data, which can greatly reduce the time required for wind field recognition. The wind field data involved in this paper are obtained by simulation. The results of data reconstruction prove that the method mentioned in this paper can describe the whole information with less samples and shorten the follow-up processing time to a certain extent, and improve the real-time recognition of low-level wind shear.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123285837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high-precision SWH can be extracted using the signal-to-noise ratio (SNR) method based on shore-based X-band radar. However, for ship-borne case, the error of the extracted SWH increases because of the motion of ship-borne radar. In this paper, the effect of ship-borne X-band radar vertical motion on SWH estimation is analyzed in detail. First, radar images of ocean wave are simulated based on linear wave theory. Then, the relationships between the illumination rate and the detection distance at different antenna heights are discussed. Finally, the effect of the vertical motion amplitude of the ship-born radar on the root square of SNR is investigated. Simulation results show that the vertical motion of the ship-borne radar is one of the main reasons for the increasement of SWH estimation error. Furthermore, the root square of SNR and the change rate of the vertical motion amplitude are negatively correlated. This work provides a significant theoretical foundation in future application for ocean remote sensing using ship-borne X-band radar.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115153144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
