Advance Technology that can be used in veichles to remove pollution
Hello I am Noorjahan Binte. Now i am studying in Computer Science & Engineering in Brac University.
Sometimes i think Covid-19 has a great impact on nature. Pollution is reduced now. So today i am glad to write details about Pollution.
Air pollution's the introduction of chemicals,particulate matter(PM), or biological materials that cause harm or discomfort to humans and other living organisms, or cause damage to the natural environment. Air is an important natural resource providing the basis of life on earth. The air in the atmosphere provides oxygen to plants and animals by virtue of which they are able to live. At the community level, reductions in air pollutants can be achieved by actively choosing to walk, cycle or take public transport rather than drive a car (DEHP, 2011). Motor vehicles should be kept in good condition and driven correctly to minimize emissions. Good urban design and planning canalso reduce pollution by having cleaner, greener choices for the public. These may include increasing walking and cycling paths and by creating a space in the urban cities where people can work, play and shop which will reduce the need to travel. Purchasing items that have low energy requirements from their manufacture and use, or that canbe recycled, also reduce the energy that needs to regenerated(DEHP, 2011). Besides the community level approach having a clean air, it is essential to devise techniques to control air pollution.
Current trends forecast that Over-the-Air (OTA) software updates will be highly significant for future connected vehicles. The OTA update will enable upgrading the vehicle functionalities or bug fixations in the embedded software installed on its Electronic Control Units (ECUs) remotely. The introduction of OTA updates in the automotive industry has brought many advantages for both the Original Equipment Manufacturer (OEM) and the driver/owner. However, in terms of security, OTA updates are highly critical as they need complete access to the in-vehicle communication network.
This survey highlights and discusses OTA software updates in the automotive sector, mainly from the security perspective. The major objective of this survey is to deliver a comprehensive outline of various research directions and approaches in OTA update technologies in vehicles. At first, we discuss the connected vehicle technology and then integrate the relationship of OTA update features with the connected vehicle. We further discuss both promising and secure OTA update approaches, that have gained a lot of attention recently. Furthermore, we present a comprehensive comparative study of the existing OTA update approaches on the basis of strengths, weaknesses and evaluation setup. The survey also focuses on the existing vehicle features that support OTA updates, and customer satisfaction and usability. Finally, we identify possible future research directions of OTA updates for automobiles, particularly in the area of security.
In recent decades, worldwide consumption of conventional road-based transportation fuels (gasoline and diesel) has increased by around 1.5% per year. In recent years, Low Emission Zones (LEZs) have been put in place or approved throughout Europe, with the United Kingdom, France and Germany all announcing that pure internal combustion engine (ICE) technology will be banned in the 2040 timescale.
As a result, various pathways to decarbonise the vehicle power train technology (and corresponding energy carriers) have been proposed including electric vehicles (electricity), fuel cells and internal combustion engines (hydrogen) and internal combustion engines (oxygenated hydrocarbons) etc.. Through a series of industry and academic consultations, the Advanced Propulsion Center has developed a consensus view of the future development and application of key power train technologies through consultation with technology developers, vehicle manufacturers and funders resulting in an increasingly complex series of technology roadmaps.
The urgent need to overcome the challenge of range has meant that the underpinning power train architecture for vehicles is evolving rapidly, as shown in Fig. 1 there are now multiple options beyond the conventional Internal Combustion Engine (ICE). Hybrid electric (P) HEV and Range-extender electric vehicles (REEVs) are seen as promising solutions for overcoming this issue. In addition, a basic battery electric vehicle (BEV) might also support a removable on-board electrical generator which is used to charge the battery during the journey. First generation range extenders (REs) are seen as conventional reciprocating internal combustion engines with attached electrical generators examples such as Lotus and Mahle Power train, second generation REs are more integrated elector-mechanically integrated solutions with third generation range extenders a wholly integrated electromagnetically solution including fuel cells, free-piston engines, rotary engines etc.. As a result, there are aggressive projections for the uptake of REEVs ranging from 8% to 30% of new vehicle sales in 2030. Hydrogen Fuel Cell vehicles (H2FC) can also present an opportunity to offer vehicle range suitable for a heavy duty vehicle with refueling times similar to current Diesel vehicles. Scarcity of hydrogen refueling infrastructure may limit uptake of this technology, however back to base refueling and on board hydrogen production (using technologies such as on board reforming ) could support greater adoption of fuel cell vehicles.
By reducing by it's cost i can inspire people to use these technologies. It's safe for environment pollution. So that people & all the creation can live peace and happily.
