Future car development will be ruled by the electronicsystem. Market research companies predict that the market for automotive electronics will expand quickly. The developmentof automotive/car electronics is governed by the demands forvehicle performance as well as passenger comfort and safety.
Performance of an Automotive –
A robust and reliable design is necessary for the lightingand sensor applications that have significantly increased as a result of the
enormous advancements in microelectronics, particularly high-power electronics.
Analysts predict a turnover of more than $80 billion with rapid growth in the
ensuing years.
Electronicperformance improvements in any car are the result of, when compared to
mechanical solutions:
• further sensor inputs
• more complex control algorithms
• smaller control time constants
• guaranteed higher thermal stability and accuracy.
There are many features available in car electronics system today that improve theoverall performance of the car, including -
• reduced air pollution
• improved engine performance
• reduced fuel consumption
• improved start-up characteristic of the engine
• constant idling speed
• spontaneous engine acceleration.
Some Automotive Electronic Systems –
MEMS - Utilizing microfabrication techniques, microelectromechanical systems(MEMS) technology combines the mechanical properties of microsensors with the
capabilities of microelectronics. These methods' benefits include low cost,
small size, and high efficiency. MEMS accelerometers are used to measure
vibrations and shocks as well as accelerations. Silicon (Si) is the
semiconductor which is used in accelerometers.
Gyroscope - MEMS gyroscopes are a popular option for motion controlbecause they make it simple to measure angular velocity. Four sensors,
including accelerometers and gyroscopes, are used in active suspension to
guarantee a stable and predictable dynamic behaviour for the car. Nano
electro-mechanical systems are creating a new MEMS market (NEMS). These
nanoscale devices are sensitive enough to provide incredibly tiny sensors that
can identify stresses and vibrations at the atomic level. a gyroscope in a car
can be used to activate the electronic stability control (ESC) braking system
to avoid an accident or to activate an airbag.
LED lighting - When it comes to high beams, brake and position lights, aswell as side and rear turn signals, LEDs are frequently used in the automotive
industry. The LED lighting system is smart because it is simple to control. The
driver IC contains the necessary protection circuits against overvoltage,
undervoltage, reverse polarity, overcurrent, short circuit, and extremely high
or low temperatures, as evidenced by the high reliability in automotive electronics
applications.
LiDAR System - LiDAR systems enable autonomous vehicles to recognizeobstacles or other moving objects in this manner. It is a lot like radar
technology. Both make use of variables like speed, angle, and range. Of course,
light waves are used for LiDAR to detect the obstacle.
Future Scope of Automotive Electronics -
As “smart” technologies have developed, beginning with smartgrids, there has been increased interest in GPS and the IoT ecosystem as a
means of assisting vehicles with the reception and transmission of high-speed
data. The car is a desirable environment for technology because of three main
factors: autonomous driving, electric cars, and the high demand for
infotainment services from consumers.
More accurate sensors and Artificial Intelligence can make itpossible for cars to prevent from accidents as well as automatic driving, or
gesture driving with accuracy. To achieve high performance with more eco
friendly design, we can have a reliable design of automobiles in future.
