Toyota’s Sudden Unintended Acceleration

University of Sharjah Electrical Computer Engineering Department PRO. SOC. ISSUES IN ENG. Term piece of music TOYOTAs sudden unint stoped acceleration Submitted to Dr. Abdul Kadir Mohammed Hamid D matchless by Asma Al-Zaabi ID20721529 Kawther Aljasmi ID20721556 foot active Toyota Toyotas attach to is a product of many long time of experience, production and high efficiency. Toyota has been angiotensin converting enzyme of the most successful companies on the whole oer the world.Toyotas society success in leading the Japans economy to be NO. 1 in Asia, beside that Toyota is a study multinational car manufacturer headquartered in Japan. It was built by Kiichiro Toyoda in 1937. Nowadays this factory is the first factory for cars in the world. And what make Toyotas so special that it manufactured fomites with high quality and simplicity in use of goods and services, beside the less costly comp ard with the other companies, which make the use of Toyota vehicles so extended.Toyo ta is the trice largest producer of vehicles all over the world with a production of 6 million vehicles per year deployed in more than 160 countries, Also arrive at an annual income of 108 billion dollars . Toyota produces a full range models of vehicles and employs 246, 700 staff. It is in wish well manner one of the top ten companies in the list of Fortune Global viosterol largest trading company, There is a survey that has been published in cnnMoney. com that Toyota is one of the most im straighten out(p)ive and appreciated company. Kiichiro Toyoda, founded the company in 1933, when he had unspoiled inverted from a tour in the United States, he choose the go factory which was confessed by his father to set up a workshop for the vehicles industry. Then he produces the first models in 1935. Introduction some the mechanism The muffle is a metal home office that connected to the end of the gas pedal this part overlooks the amount of the air that go to the vehicles engi ne. And the gag eubstance consists of 4 main parts which is ? the leap plate or scarceterfly valve ? electronic throttle control sensing element ?Engine Control Unit (ECU) Talking about the throttle body we have to give you an explanation about it. The main part on the throttle body is the throttle plate, which is a butterfly valve that controls the Intel gases. The throttle plate is communicated by a site of wire. To move the throttle plate in that location is an electronic throttle control that connects the throttle linkages and the accelerator pedal to a sensor which withdraw the signal to the Engine Control Unit (ECU), which calculate the angel and give the exact position of the plate depending on the inputs.We tail assembly say that this part is controlled partially by the device driver when he press on it the throttle the plate or the butterfly valves pass on be opened and the angle is depending on the propel you apply it the more force the largest angle and vice ve rsa. The chore Unintended acceleration is the main trouble in Toyotas role. Where you suddenly feel like your vehicles speed is increasing up without any order from you to increase, and according to almost pillow slips what was happen that if you press on the pedals to drive by 80 km speed you notice that the vehicle is move according to 120 km speed and that is the basic problem here.Most of t he people archetype that this problem is be constitute of two reasons. The first one that when you drive the vehicle and tour you applying your force on the gas pedals it stuck and it squirtt be relapse to its normal position so this lead to our big problem the inadvertent acceleration . The second reason that the gas pedals didnt stuck, but it take more time to return to its normal position this also cause the unintended acceleration that happen to the vehicle.These two reasons cause a tummy of accidents resulting with number of finales and injuries Toyota documented this proble m by recalling 4. 2 million vehicles to switch over the floor mats that might impede the pedals and what they did about this office is reducing the continuance of the floor mat from the top of it so the pedal can return easily without any difficulty, beside 2. 4 million to install a shim buns the electrical pedals assembly to make it return to its normal position at the expected time.All the pedals that argon used in Toyotas vehicles were manufactured by Canadian supplier CTS. Toyotas engineer thought that the problem is lick for these pedals that it take time to return slow down or by chance its sticking in the floor mat . The problem Contd. By doing the biggest recall ever Toyotas thought that this is the end of the problem, but unluckily and according to the complaints of 24,000 customers received by the NHTSA (National Highway Traffic guard Administration) from Toyotas vehicles users about problems in their vehicles.The cases of deaths and injuries is still recording , so Toyota has to do something with the dodge as a whole not only with the parts, and the NHTSA has eventually conclude that in that respect was no mechanical problem It was not easy for Toyota to make the real problem and it took long time to identify the issue they got impoverished if the issue is not about the two recalling or its about the body as whole or there is a problem about the electrical throttle concept.At the same time mike Allen-senior automotive editor in chief delves into modern car tech, explaining wherefore widespread theories about electrical throttle problems and electromagnetic interference are misguided and he was making his own research about electromagnetic interference from devices. And he conclude that there is electrical devices in the cars contribute to the acceleration problem like mobile phone phones , navigators , TVs and cameras. The problem Contd. consort to this simple figure we lead explain how Mike Allen proved his results about the electromagnetic inference and how its related to our case We will start with process backward. The electronic throttle represented by the Actuators and its any part in the vehicles that take the action and the throttle is controlled by the ECU Engine Control Unit which can be compared to the central processing unit function in our PCs , All the process that happen in the vehicles moldiness pass through the ECU . Lets start with the main point of the case when you press on the pedals. There is a sensor that converts your suit into an electrical signal. And when these signals inter baptismal font with the external signals which are brought by the electrical devices the vehicles fuck off out of control.It speeds up and this is cause the sudden acceleration even the breaks cant react in this case. We can simply summarize this case as the heart attack. When you go to the hospital and you checked that e actuallything is doing its work very well. You cant recognize that there is an y problem in your body and you cant estimate when the heart attack will happen it happens suddenly. This is so related to Toyotas case where the vehicles parts are is our organs and the heart attack is the unintended acceleration. It can be also summarized by the Hackers .When you received a virus from external resource like flash memories and websites you cant blame the PCs Company because its not their fault. Also we cant blame Toyota because they cant control this wide problem. Also people notice that this problem become self-evident in the snowy weather, because as we know that the vehicle slides if the street is squiffy , so imagine what would happen if the way is snowy beside that the vehicle is out of control and its speeding up , That will lead for misfortune for sure Why this happen with Toyota only ? 1- Some parts are manufactured by another(prenominal) company, so it differ from one to another like in our case the pedals was manucfaterd by Canadian supplier. 2- The sen sitivity of the remains ECU is differing from car to another. 3-This problem happen with more than automotive company , but the media focus on Toyota only because it is one of the successful companies in US and the middle east and the other companies like General forces and Ford motor took it as chance to shine What did TOYOTA do? Toyoda apologizes in tears Toyoda state that he wanted more than anyone else for Toyota to be safe. He said in English before they start answering questions through an interpreter My telephone is on every car. , The Chairman of Toyotas Akio Toyoda apology to the American Congress and the users of company cars in the United States for a bug in the pedals speed in some categories of Toyota, which have caused traffic accidents, and he conclude this investigation by saying we will double the quality . Recalling processNHTSA (National Highway Traffic Safety Administration) has received complaints from the customers who complain about the unintended accelera tion of their TOYOTAs vehicles, then Toyota asked NHTSA to help them in contacting with their customers. Toyota has recalled more than 8 million vehicles worldwide for problem related to sudden acceleration, which have been blamed for several accidents resulting in injuries and death . The automaker has repeatedly apologized for the lapses in quality control and TOYOTA technicians are running(a) extended hours to repair the recalled vehicles, and the actual repair takes like 30 min. orks and TOYOTA will cover all costs associated with work. Educating the public On the other overhaul Toyota focused on educating the users of Toyota vehicles about the problem itself , what to do if the customer face such a problem , what is the procedure that should be taken if the driver face this while he/she is driving , and a lot of entropy and details posted on their website. Also the concern about contacting with all the customers who has the vehicles that has this bug. What did TOYOTA do in U. A. E.?The Ministry of Economy appointed an officer to follow up on repairs and maintenance carried out by the company Al-Futtaim Motors Agents of Toyota company in UAE- to address the problem that might occur in these models of cars Avalon Sequoia which are more than 3200 cars during the period ranging from one month (24 February to 24 March ) The cypher of Ethics of Toyota At Toyota, safety is a priority in everything we do from the vehicles we put on the road to the people who drive them. Thats why we sponsor programs across the U.S . That encourage safety for drivers and passenger alike Akio Toyoda According to this statement we drive the main ethical rule about our case, and Toyotas case is the only case that was taken from the positive side come after the law. To be honest in word and deed. Respect the values of society. existence responsible. Perform their duties in accordance with the law To have rules of conduct use of good governance and to avoid actions th at could lead to conflict between the company and personal interests of society.Conclusion At the end, we can say that this problem is out of Toyotas hand, although they do all what they can do in this case and they tried and true to limit this case as much as they can. Its loose What would Toyota do if the guy next to you at a traffic liberal answered his cell phone? Or some ghost in the political machine or a hacker caused a software glitch that make your car run away and the brakes suddenly fail? Toyota deserves a better deal than the media and Congress are giving it.
