Michael Barr (software Engineer)
Michael Barr is a software engineer specializing in software design for medical devices and other embedded systems. He is a past editor-in-chief of Embedded Systems Design magazine and author of three books and more than seventy articles about embedded software. Barr has often worked as an expert witness, including testifying in the Toyota Sudden Unintended Acceleration litigation. In October 2013, after reviewing Toyota's source code as part of a team of seven engineers, he testified in a jury trial in Oklahoma that led to a "guilty by software defects" finding against Toyota. There are several technical articles that discuss the various electronic throttle control defects he testified were linked to unintended acceleration that caused deaths in Toyota Camry vehicles. Earlier in his career, Barr testified as an expert witness in the DirecTV anti-piracy end user litigation, which involved over 25,000 end users. He has also worked as a testifying expert witness in other high-p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Engineer
Software engineering is a systematic engineering approach to software development. A software engineer is a person who applies the principles of software engineering to design, develop, maintain, test, and evaluate computer software. The term ''programmer'' is sometimes used as a synonym, but may also lack connotations of engineering education or skills. Engineering techniques are used to inform the software development process which involves the definition, implementation, assessment, measurement, management, change, and improvement of the software life cycle process itself. It heavily uses software configuration management which is about systematically controlling changes to the configuration, and maintaining the integrity and traceability of the configuration and code throughout the system life cycle. Modern processes use software versioning. History Beginning in the 1960s, software engineering was seen as its own type of engineering. Additionally, the development of softwa ...

Embedded System
An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is ''embedded'' as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems. In either case, the processor(s) used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toyota
is a Japanese multinational automotive manufacturer headquartered in Toyota City, Aichi, Japan. It was founded by Kiichiro Toyoda and incorporated on . Toyota is one of the largest automobile manufacturers in the world, producing about 10 million vehicles per year. The company was originally founded as a spinoff of Toyota Industries, a machine maker started by Sakichi Toyoda, Kiichiro's father. Both companies are now part of the Toyota Group, one of the largest conglomerates in the world. While still a department of Toyota Industries, the company developed its first product, the Type A engine in 1934 and its first passenger car in 1936, the Toyota AA. After World War II, Toyota benefited from Japan's alliance with the United States to learn from American automakers and other companies, which would give rise to The Toyota Way (a management philosophy) and the Toyota Production System (a lean manufacturing practice) that would transform the small company into a leader in t ...

Sudden Unintended Acceleration
Sudden unintended acceleration (SUA) is the unintended, unexpected, uncontrolled acceleration of a vehicle, often accompanied by an apparent loss of braking effectiveness. Such problems may be caused by driver error (e.g., pedal misapplication), mechanical or electrical problems, or some combination of these factors. The US NHTSA estimates 16,000 accidents per year in the United States occur when drivers intend to apply the brake but mistakenly apply the accelerator. Definition and background In the 1980s, the U.S. National Highway Traffic Safety Administration (NHTSA) reported a narrow definition of sudden acceleration only from near standstill in their 1989 ''Sudden Acceleration Report'': "Sudden acceleration incidents" (SAI) are defined for the purpose of this report as unintended, unexpected, high-power accelerations from a stationary position or a very low initial speed accompanied by an apparent loss of braking effectiveness. In a typical scenario, the incident begins at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Throttle Control
Electronic throttle control (ETC) is an automobile technology which electronically "connects" the accelerator pedal to the throttle, replacing a mechanical linkage. A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM). The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches. The electric motor is then used to open the throttle valve to the desired angle via a closed-loop control algorithm within the ECM. The benefits of electronic ...

Toyota Camry
The Toyota Camry (; Japanese: トヨタ・カムリ ''Toyota Kamuri'') is an automobile sold internationally by the Japanese auto manufacturer Toyota since 1982, spanning multiple generations. Originally compact in size (narrow-body), the Camry has grown since the 1990s to fit the mid-size classification (wide-body)—although the two widths co-existed in that decade. Since the release of the wide-bodied versions, Camry has been extolled by Toyota as the firm's second "world car" after the Corolla. , the Camry is positioned above the Corolla and below the Avalon or Crown in several markets. In Japan, Camry was once exclusive to ''Toyota Corolla Store'' retail dealerships. Narrow-body cars also spawned a rebadged sibling in Japan, the Toyota Vista (トヨタ・ビスタ)—also introduced in 1982 and sold at ''Toyota Vista Store'' locations. Diesel fuel versions have previously retailed at ''Toyota Diesel Store''. The Vista Ardeo was a wagon version of the Vista V50. Between 197 ...
