AutoPC
A carputer, or car-puter, is a computer with specializations to run in a car, such as compact size, low power requirement, and some customized components. The computing hardware is typically based on standard PCs or mobile devices. They normally have standard interfaces such as Bluetooth, USB, and Wi-Fi, WiFi. The first carputer was introduced by Clarion (company), Clarion on December 4, 1998, although on-board diagnostics have been employed since the 1980s to precisely measure the amount of fuel entering the engine as the carburetors got too complex. A challenge to installing a computer in a car is the power supply. Energy is supplied as a nominal 12 VDC in cars or 24 VDC in some trucks. The voltage varies according to whether the engine is on or off since the battery generally delivers 12V, while the generator supplies more. There can be peaks, and at ignition time the supply current drops. External DC/DC converters can help to regulate voltages. Police cars often have Mobile dat ...

Windows CE
Windows Embedded Compact, formerly Windows Embedded CE, Windows Powered and Windows CE, is an operating system subfamily developed by Microsoft as part of its Windows Embedded family of products. Unlike Windows Embedded Standard, which is based on Windows NT, Windows Embedded Compact uses a different hybrid kernel. Microsoft licenses it to original equipment manufacturers (OEMs), who can modify and create their own user interfaces and experiences, with Windows Embedded Compact providing the technical foundation to do so. The current version of Windows Embedded Compact supports x86 and ARM processors with board support package (BSP) directly. The MIPS and SHx architectures had support prior to version 7.0. 7.0 still works on MIPSII architecture. Originally, Windows CE was designed for minimalistic and small computers. However CE had its own kernel whereas those such as Windows XP Embedded are based on NT. Windows CE was a modular/componentized operating system that served as ...

Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet ...

Vehicular Communication Systems
Vehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion. Both types of nodes are dedicated short-range communications (DSRC) devices. DSRC works in 5.9 GHz band with bandwidth of 75 MHz and approximate range of . Vehicular communications is usually developed as a part of intelligent transportation systems (ITS). History The beginnings of vehicular communications go back to the 1970s. Work began on projects such as Electronic Route Guidance System (ERGS) and CACS in the United States and Japan respectively. While the term Inter-Vehicle Communications (IVC) began to circulate in the early 1980s.

ELM327
The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors. The original ELM327 was implemented on the PIC18F2480 microcontroller from Microchip Technology. While in business, ELM Electronics also sold other variants of the product, with slightly different part numbers, which implemented only a subset of the OBD protocols. In June 2020, ELM Electronics announced it was closing the business in June 2022. Uses The ELM327 abstracts the low-level protocol and presents a simple interface that can be called via a UART, typically by a hand-held diagnostic tool or a computer program connected by USB, RS-232, Bluetooth or Wi-Fi. New applications include smartphones. There are a large number of programs available that connect to the ELM327. The function of such software may inclu ...

Handsfree
Handsfree is an adjective describing equipment that can be used without the use of hands (for example via voice commands) or, in a wider sense, equipment which needs only limited use of hands, or for which the controls are positioned so that the hands are able to occupy themselves with another task (such as driving) without needing to hunt far afield for the controls. Devices that are typically used for handsfree communication use Bluetooth as its wireless technology. They still require a smartphone or other device to initiate a call. These devices include Bluetooth headsets, hands-free car kits (HFCK), and personal navigation devices (PND). Originally introduced as optional features connected by a wire to smartphones or other communication devices, they now generally are available with wireless technology. Bluetooth handsfree options are now also easily found in any high end automotive as part of the vehicle's stereo system, or in after market stereo system units. This option ...
