Design methodology of advanced driver assistance systems for urban electric vehicle
Th e article presents the design methodology of Advanced Driver Assistance Systems (ADAS) for electric vehicles. As an example the Blind Spot Information System (BLIS) is described, which was created for an urban electric car - Bytel, the vehicle constructed within the Smart Power project. A specialized soft ware was used, TASS PreScan, the soft ware created for the purposes of advance driver鈥檚 assistance systems design. Th e article discusses the following stages of ADAS system creation - the needs analysis, the designing and the model testing. Within the needs analysis there are such subcategories as the needs defi nition, the project goals and the project planning . Th e designing part focuses on two aspects: choosing the proper tool for designing and testing ADAS model and creating the system model, including data processing system and control system. Th e model testing section includes test planning and testing procedure description. Th e article ends with conclusions and future directions of the proposed model developmen
Zaawansowane uk艂ady wspomagania bezpiecze艅stwa kierowcy dla pojazdu typu miejskiego
Smart Power Team is currently working on the design of an urban electric vehicle designed to compete in the Shell Eco-marathon. One important aspect of this type of vehicle characteristics is it safety. The project of advanced driver assistance systems has included some proposals of such systems and the concept of their execution. The first concept, BLIS (Blind Spot Information System), is to build a system of informing a driver about vehicles appearing in the blind spot. The system constitutes a second concept, CDIS (Collision Detection and Information System), and it is designed to detect a vehicle collision and inform the team. Further systems are: DPMS (Dew Point Measurement System) - a system which does not allow a situation, where the windows are fogged, OHRS (Overtaking Horn Reminder System) - a system which checks overtaking and MSS (main supervision system) - a supervisory system. These concepts are based on the assumption of the use of laser sensors, photoelectric, humidity and temperature, and other commercially available systems. The article presents a detailed description of driver assistance systems and virtual prototyping methodology for these systems, as well as the numerical results of the verification of one of the systems.Zesp贸艂 Smart Power pracuje przy budowie elektrycznego pojazdu miejskiego, projektowanego na potrzeby zawod贸w Shell Eco-marathon. Jednym z aspekt贸w charakteryzuj膮cych pojazd jest jego bezpiecze艅stwo. Projekt system贸w wspomagaj膮cych kierowc臋 zawiera kilka propozycji system贸w i koncepcji ich wykonania. Pierwsz膮 koncepcj膮 jest BLIS (Blind Spot Information System), kt贸rego zadaniem jest informowanie kierowcy o pojazdach pojawiaj膮cych si臋 w martwym punkcie. Drug膮 koncepcj臋 stanowi CDIS (Collision Detection and Information System) i jest projektowany do wykrywania zderzenia pojazd贸w i informowania o tym zespo艂u. Kolejnymi systemami s膮: DPMS (Dew Point Measurement System) - nie dopuszcza do sytuacji, w kt贸rej szyba jest zaparowana, OHRS (Overtaking Horn Reminder System) - system wykrywaj膮cy wyprzedzanie pojazdu oraz MSS (Main Supervision System) - system nadzorczy. Koncepcje zak艂adaj膮 u偶ycie czujnik贸w: laserowych, fotoelektrycznych, wilgotno艣ci oraz temperatury, a tak偶e innych system贸w stosowanych komercyjnie. Artyku艂 przedstawia szczeg贸艂owo opisane systemy wspomagania kierowcy oraz metodologie wirtualnego prototypowania dla tych system贸w, a tak偶e wyniki numeryczne weryfikacji jednego z system贸w
Badania por贸wnawcze uk艂ad贸w nap臋dowych wysokosprawnego pojazdu elektrycznego
When constructing the electric vehicle for the Shell Eco-marathon competition in Urban Concept category, the Smart Power Team had to face the problem of choosing the perfect drivetrain. For this purpose, two bests concepts were studied. The first concept assumed the use of high-speed BLDC motor along with belt transmission with toothed belt. The second concept assumed the low-speed BLDC hub motor. The research was conducted for the MuSHELLka vehicle on the roller dynamometer. The aim of the research was to compare both concepts. The main selection criterion was the performance of both systems, measured at constant load and speed range of 0-30 km/h. The measurements were carried using the National Instruments hardware and software devices, the analysis of the results was performed in MATLAB software. This article includes the accurate description of the measuring circuit, the course of the research, data analysis and conclusions.W trakcie projektowania elektrycznego bolidu startuj膮cego w zawodach Shell Eco-marathon w kategorii Urban Concept zesp贸艂 Smart Power napotka艂 problem wyboru najlepszego nap臋du. Z wielu mo偶liwych opcji zosta艂y wst臋pnie wybrane dwa rozwi膮zania. Pierwsze zak艂ada艂o zastosowanie szybkoobrotowego silnika BLDC z przek艂adni膮 z p艂askim pasem z臋batym. Drugie rozwi膮zanie zak艂ada艂o zastosowanie wolnoobrotowego silnika BLDC zabudowanego w pia艣cie. Do ostatecznego wyboru rozwi膮zania konstrukcyjnego zdecydowano si臋 na dokonanie bada艅 na stanowisku badawczym obejmuj膮cym hamowni臋 podwoziow膮 opracowana specjalnie do tych cel贸w. Badanie obejmowa艂o identyfikacje rzeczywistych osi膮g贸w nap臋d贸w w ca艂ym zakresie pr臋dko艣ci roboczych 0-30 km/h. Pomiar贸w dokonano z zastosowaniem aparatury pomiarowej National Instruments natomiast analiz臋 wynik贸w wykonano w 艣rodowisku oprogramowania MATLAB. W artykule opisano szczeg贸艂owo tor pomiarowy, plan i przebieg bada艅 oraz wyniki analizy danych wraz z ostatecznymi wnioskami
