Car Electronics

Car Electronics. The earliest electronics systems available as factory installations were vacuum tube car radios, starting in the early 1930s. The development of semiconductors after WWII greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing about 1955.

One of the most demanding electronic parts of an automobile is the engine control unit (ECU). Engine controls demand one of the highest real-time deadlines, as the engine itself is a very fast and complex part of the automobile. Of all the electronics in any car, the computing power of the engine control unit is the highest, typically a 32-bit processor.

These control the transmission system, mainly the shifting of the gears for better shift comfort and to lower torque interrupt while shifting. Automatic transmissions use controls for their operation, and also many semi-automatic transmissions having a fully automatic clutch or a semi-auto clutch.
