This is in response to growing calls for environmental sustainability and reduction in carbon footprint. Presently, there are five million electric vehicles on the world’s roads. China dominates the global electric vehicles market, followed by Europe and the United States. Technological advancements have paved the way for substantial price cuts in battery prices, key stimulators being research and development in battery chemistry and burgeoning battery production for electric vehicles. The fall in battery prices is attributed to increased economies of scale generated by the EV market. Unfortunately, the novel coronavirus outbreak, commonly known as COVID-19, has crippled the entire world. With the number of cases rising exponentially every day, the international community is finding it exceedingly difficult to seek treatment for the infected patients. The rate of infections is asymmetrically distributed. While countries such as Singapore are witnessing a resurgence, Western Europe has reached a plateau, thus debating whether they should reopen their economies or not.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"41 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81070915","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}

This can only be attained through connected and autonomous vehicles integrated into intelligent transport systems and a sustainable mobility system. This requires a cost-effective, fast,and efficient development process for advanced connected and autonomous vehicle functions. In this article, a methodology to develop low-speed Adaptive Cruise Control (ACC), which is one of the most important functions of an autonomous vehicle, is explained. Vehicle tracking at slow speeds is a problem especially for conventional vehicles with high levels of nonlinearities in the powertrain system. As a part of a university-industry collaboration project “SAE level 3 autonomous bus development”, a flexible and realistic discrete plant model including longitudinal vehicle and powertrain model has been developed and discrete low-speed ACC is designed. The plant model aims to perform detailed and realistic software tests of autonomous features, which interfaces with the vehicle controllers. OKAN_UTAS autocorrectedmulti-parameter longitudinal model is integrated. For engine modeling via shaft dynamometer the 3D map of the engine is reproduced. The transmission characteristics were prepared through the road tests. To increase the reliability of the developed functions, Software in the Loop (SIL) and Model in the Loop (MIL) simulations were conducted before the on-road vehicle tests. Finally, C code with the MISRA C standard of ACC is generated and embedded into a real-time platform. The plant model, ACC design, and Model in the Loop test results are presented.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"41 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77708071","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 proposed collision safer device has one free rotation wheel installed horizontally at the vehicle lower front left and right corners, respectively. The wheels will be the first contact of the vehicle in non-perpendicular forward collisions, the collision force component parallel to the collision surface will cause the wheel rotating and make the vehicle rolling slide along the direction of the parallel force component, therefore, the collision will be softer and less harmful, so lives could be saved and property damage could be reduced. The collision test with mini 3D printed models shows that the collision safer device will significantly extend the moving distance after the vehicle collides into a roadside crash barrier in the relatively small collision angle and give the vehicles behind more time and distance to slow down, so the severity of the rear-end collision will be reduced, lives will be saved, even the collision can be avoided. This collision safer device is simple, low cost and can be added to the current design of all types of common vehicles without major modification of the structures.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"87 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84198566","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}

All the paper work performed on Isuzu engine 4HF1 which is 4 cylinder diesel engine working with fully mechanical fuel injection system. To develop mechatronics fuel system, must install crank sensor which measure the engine speed in rpm and specify the piston position, cam sensor which specifies the injection order, common rail fuel injection system which includes electronic injectors, high pressure pump and common rail, ECU which control all the system inputs and outputs, and injectors driver controller which responsible for delivering the required high voltage for the injectors with high speed switching. ECU software will be developed from scratch to develop injection quantity, injection time and injection order output signals to be compatible with the common rail fuel system. Mathworks tools (Matlab-Simulink-Stateflow) will be used for developing ECU software application layer which divided into many models as crank shaft speed model, crankshaft sensor piston position, cam sensor injection order model,pedal speed model, injectors model, torque model and final model which collect all the previous models. Embedded coder toolbox will be used for generating C code which will be integrated with the microcontroller layer and uploaded to the selected ECU.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"21 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81429246","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}

Ninety different auto-maintenance jobs executed by automobile, heavy duty, generator and panel beater auto firms between, Januarys to December, 2016 were analyzed using direct observation. Furthermore, primary data collected were analyzed using MS Excel 2013 and Minitab 17 software. Results revealed the mean performance rating of workshops on the availability and usage of personal protective equipment as 143.9 and 154.7. While 224.2 and 302.7 constitutes respective poor usage rate and non-availability of personal protective equipment in the respective workshops. Results further revealed 58.2% as average productive lost time rate resulting from accident occurrence. Conversely, regression analysis revealed that a unit increase of 659.2, 63.5 and 82.8 in accident, severity and lost time index, caused a decreased of -150.8 in overall productivity lost factor. With a coefficient of determination (R2 ) of 72.01% at p-value less than 0.005. Hence, a positive and significant relationship between accident and auto mechanics time performance exist. Therefore, sensitization of stakeholders in this sector on the usage of personal protective equipment and the need to make safety their priority as well as regular inspection for safety compliance by regulatory bodies are recommended to build customers trust and improve productivity in this sector","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"11 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77708174","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}
