The automotive industry comprises a wide range of companies and organizations involved in the design , development , manufacturing , marketing , selling , repairing , and modification of motor vehicles . It is one of the world's largest industries by revenue (from 16% such as in France up to 40% to countries such as Slovakia).
49-689: A power-train control module , abbreviated PCM , is an automotive component, a control unit, used on motor vehicles . It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control Module (BCM), for a total of three separate computers. These automotive computers are generally very reliable. The PCM commonly controls more than 100 factors in

The vehicle propulsion is provided by an engine or motor, usually an internal combustion engine or an electric motor , or some combination of
147-459: A car or truck. There are many hundreds of error codes that can occur, which indicates that some subsection of the car is experiencing a problem. When one of these errors occurs, usually it will turn on the "check engine" light on the dashboard. The PCM is one of potentially several on-board computers, or essentially the "brain" of the engine control system. The primary inputs to the PCM come from many sensors, of different types, that are spread around
196-430: A car, and prefer other modes of transport. Other potentially powerful automotive markets are Iran and Indonesia . Emerging automobile markets already buy more cars than established markets. According to a J.D. Power study, emerging markets accounted for 51 percent of the global light-vehicle sales in 2010. The study, performed in 2010 expected this trend to accelerate. However, more recent reports (2012) confirmed

More than one million plug-in electric passenger cars and vans have been registered in Europe by June 2018, the world's second largest regional plug-in stock after China. Norway is the leading plug-in market in Europe with almost 500,000 units registered as of December 2020 . In October 2018, Norway became

In developing countries vehicle ownership rates rarely exceed 200 cars per 1,000 population. The following table summarizes the evolution of motor vehicle registrations in the world from 1960 to 2019: Since the early 2000s, the number of alternative fuel vehicles has been increasing driven by

Production processes that use a significant volume of water include surface treatment, painting, coating, washing, cooling, air-conditioning, and boilers, not counting component manufacturing. Paintshop operations consume especially large amounts of water because equipment running on water-based products must also be cleaned with water. In 2022, Tesla's Gigafactory Berlin-Brandenburg ran into legal challenges due to droughts and falling groundwater levels in

The Detroit branch of Boston Consulting Group predicted that, by 2014, one-third of world demand would be in the four BRIC markets (Brazil, Russia, India, and China). Meanwhile, in developed countries, the automotive industry has slowed. It is also expected that this trend will continue, especially as the younger generations of people (in highly urbanized countries) no longer want to own

As of 2017 , the country's fleet also includes more than 160,000 natural gas vehicles , mainly transit buses and delivery fleets. Despite its relative small size, natural gas use accounted for about 52% of all alternative fuels consumed by alternative transportation fuel vehicles in the U.S. in 2009. The 27 European Union (EU-27) member countries had

The process evolved from engineers working on a stationary car, to a conveyor belt system where the car passed through multiple stations of more specialized engineers. Starting in the 1960s, robotic equipment was introduced to the process, and most cars are now mainly assembled by automated machinery. For many decades,

Navigant Consulting forecasts that the global stock of light-duty motor vehicles will reach 2 billion units in 2035. Global vehicle ownership in 2010 was 148 vehicles in operation per 1,000 people, a ratio of 1:6.75 vehicles to people, slightly down from 150 vehicles per 1,000 people in 2009,

In 1980, the U.S. was overtaken by Japan and then became a world leader again in 1994. Japan narrowly passed the U.S. in production during 2006 and 2007, and in 2008 also China , which in 2009 took the top spot (from Japan) with 13.8 million units, although the U.S. surpassed Japan in 2011, to become

As of 2016 , the stock of alternative fuel vehicles in the United States included over 20 million flex-fuel cars and light trucks , the world's second-largest flexible-fuel fleet in the world after Brazil . However, actual use of ethanol fuel is significantly limited due to the lack of E85 refueling infrastructure. Regarding
