The first computer used in a car: the ECU (Engine Control Unit)
VW's first automotive computer (1968)
The first use of a computer in a car was simply for the purpose of engine control. Automotive manufactures began introducing early versions of computer controlled systems to perform one specific function; In 1968, Volkswagen introduced the first vehicle with a computer controlled electronic fuel injection (EFI) system - the D-Jetronic, a transistorized electronic module manufactured by Bosch. It was offered as standard equipment on their Type-3 models.
ECU's have become a standard device on most cars since the late 1970's when they became necessary due to increasingly stringent government emission standards. Starting in 1973 all Chrysler models would come with an ECU as standard equipment. By 1975, the ECU would be found in all U.S. made automobiles.
Controlling the engine is the most processor-intensive job on your car, and the engine control unit is the most powerful computer on most cars. The ECU uses closed-loop control, a control scheme that monitors outputs of a system to control the inputs to a system, managing the emissions and fuel economy of the engine (as well as a host of other parameters).
Gathering data from dozens of different sensors, the ECU knows everything from the coolant temperature, to the amount of oxygen in the exhaust.
With this data, the ECU performs millions of calculations each second, including looking up values in tables, calculating the results of long equations to decide on the best spark timing and determining how long the fuel injector is open. The ECU does all of this to ensure the lowest emissions and best mileage.

Putting the first Microprocessor chips in cars
Ford & Motorola PTEC Automotive Microcontroller chips (1994)
In 1976, General Motors (GM) announced a new partnership with Motorola Semiconductor to develop a Custom Microcomputer for use in their vehicles. By 1981, all GM vehicles would be equipped with their new Computer Command Control System ("CCC") emission control system that featured an ECM (Electronic Control Module) that featured a Motorola 6802 based 8-bit microprocessor manufactured by Delco Electronics. During the late 1980's, GM and Chrysler ECM's would both begin using the 16-bit Motorola 68HC11 microcontroller chip in their vehicles.
In 1983, Intel and Ford started a joint venture building EEC ( Electronic Engine Control) units now known as ECU (Electronic control Units). These ECU's used custom Intel 8061 (a derivative of the Intel 8096 Micro-controller) and later used 8065, 83251 & 8051 microcontroller chips for its processing functions. The 8061 micro-controllers and its derivatives were used in almost all Ford automobiles built from 1983 thru 1994.
In 1994, in a last attempt to save the slowing EEC IV microcontroller, Ford used two Intel 8065 16-bit chips inside the controller. Shortly thereafter, Ford would be ready to end their long use of Intel micro-controllers and transition to using Motorola's new 32-bit PTEC controllers. In 2005, Intel announced they were discontinuing production of all automotive versions of their microcontroller chips.
Previously in 1991, Ford's Electronics Division had announced they would partner with Motorola Semiconductor Products Sector to supply them with future electronic engine & transmission microcontroller chips to be used in Ford's upcoming Powertrain Electronics Controller (PTEC). The PTEC controller was originally going to use the MC88300 32-bit embedded RISC chip that Motorola had in development but would later cancel. Ford choose instead to use Motorola's new custom designed 32-bit RISC based PowerPC processor chip. PTEC microcontrollers were used in Ford vehicles starting in 1994, replacing the Intel designed EEC IV microcontroller chips that Ford had used since back in 1983.
