Automotive Electronics: Subsystems and Trends

June 26, 2020
    Nowadays we stepped into an industrial epoch in which connected vehicles are the new norm. As a result, the market is seeing a growing demand for electric vehicles, increased penetration of advanced vehicle safety systems, and a boom in mobility sharing technologies. Moreover, autonomous vehicles have appeared on the market only about a decade away. All of this is leading to an increased need for automotive electronics.

Automotive electronics are electronic systems used in vehicles, including engine management, ignition, radio, carputers, telematics, in-car entertainment systems, and others. Ignition, engine and transmission electronics are also found in trucks, motorcycles, off-road vehicles, and other internal combustion powered machinery such as forklifts, tractors and excavators. Related elements for control of relevant electrical systems are also found on hybrid vehicles and electric cars.

Automotive electronics can be subjected to, and are therefore rated at, more extreme temperature ranges than commercial (i.e. normal) electronics.

According to an industry report published by Global Market Insights, the automotive electronics market is expected to grow at a compound annual growth rate of 7 percent between 2020 and 2030. While mature automotive markets may stagnate as consumers increasingly opt for shared mobility solutions over car ownership, a raft of dynamic industry changes is opening up fresh opportunities in digitization, connectivity and electrification. This is good news for manufacturers of electronic components, given that they are the foundation of many innovations in mobility.

Due to pervasive electronics systems in automobile operations, manufacturers have been able to improve the driving performance, efficiency of fuel, and both the driver’s and riders’ comfort. It is remarkable to note that the number of electronics components are progressively increasing with time because of the need to improve everything from fuel efficiency and driver safety.

Electronic Subsystems:

  • Engine Ignition
  • Fuel Injection
  • Anti-lock Brakes
  • Collision Avoidance Systems
  • Navigation System
  • Air Conditioning
  • Safety Controls
  • Transmission Controls
  • Seat Control
  • Security Alarms
  • Steering Control
  • Music System
  • Head and side lights

Here are some of the Automotive Electronics Trends

Advanced Motor Control

Digital vector control algorithms capable of delivering full torque with acceleration and deceleration at rates that can be precisely managed. The Intelligent Drives Kit combines a full complement of development software, motor control reference designs and hardware. Cars already are controlled by computers. However, motor management systems will get more sophisticated. If a daily commute takes the vehicle on crowded city streets, the car knows that, and it makes the motor use less gas, for instance.

Driverless Vehicles

Autonomous vehicle technology may be able to provide certain advantages compared to human-driven vehicles. Increased safety on the road is one of the most essential – vehicle crashes cause many deaths every year, and automated vehicles could potentially decrease the number of casualties as the software used in them is likely to make fewer errors in comparison to humans. A decrease in the number of accidents could also reduce traffic congestion, which is a further potential advantage posed by autonomous vehicles. Autonomous driving can also achieve this by the removal of human behaviours that cause blockages on the road, specifically stop-and-go traffic.

Another possible advantage of automated driving is that people who are not able to drive – due to factors like age and disabilities – could be able to use automated cars as a more convenient way of transportation.

Electric Vehicles

The ecological factor is increasing the demand for electronic vehicles, increasing availability of charging stations and improvements in vehicle range as well. All-electric vehicles run on electricity only. They are propelled by one or more electric motors powered by rechargeable battery packs. Electronic vehicles have several advantages over conventional vehicles: energy efficiency, better performance, reduced energy dependence and eco-friendliness.

Automotive Cameras

Advanced driver assistance systems and camera monitoring systems use a huge variety of automotive cameras. Autonomous vehicle runs purely with the help of powerful automotive cameras. Here are the types of automotive cameras: side-view cameras, interior-view cameras, forward-view cameras, rear-view enhancement, and corner-view cameras.

The demand for sensor cameras for the purpose of advanced driver assistance systems (ADAS) is increased significantly, with a rising focus on safety measures on the back of road accidents. Automotive cameras have evolved considerably due to integration with vehicles safety systems.

Shared Mobility

Consumers have embraced the convenience and affordability of shared mobility in the form of ride-hailing and car-sharing services. This trend has also spawned related businesses specializing in sharing services for e-bikes and e-scooters. The percentage of new vehicle sales for these applications “may range between 10-15 percent in the US and Europe and up to 35 percent in China by 2025,” according to a Roland Berger Global Automotive Supplier Study. These disruptive new markets have already given rise to a range of innovative electronic management systems, and this trend is likely to continue.


Regulations regarding safety, security and emissions reductions are adding to the push for greater connectivity, and expanding the market for advanced driver-assistance system (ADAS) technologies. Automotive manufacturers are developing new, lightweight components to increase energy efficiency, and ADAS features such as automated emergency braking (AEB) and lane departure warning systems are on the verge of becoming mainstream applications.
