What Role Do Embedded Systems Play in Automotive Development?

If you're following the latest trends in automotive technology, it will be no surprise that embedded systems are at the heart of industry innovation. As vehicles become more advanced, these systems play a vital role in enhancing everything from safety to the driving experience.

In this guide, we explore some of the key automotive embedded systems as we highlight how they are reshaping the industry. We also dive into the ongoing shift towards electric vehicles and how this impacts embedded systems.

So, first, let’s dive into how embedded systems are shaping the future of automotive development:

Top 5 Automotive Embedded Systems

In case you didn’t already know, Automotive embedded systems are electronic components integrated into vehicles to control and manage various functions. They consist of microcontrollers, sensors, actuators, and software working together to enable specific functionalities. 

Automotive embedded systems are designed to perform tasks such as engine management, transmission control, navigation, entertainment, and safety features.

Here are some of the most impactful automotive embedded systems that are transforming the industry:

1. Adaptive Cruise Control (ACC) Systems

Embedded systems have taken cruise control to the next level. What used to be a simple speed-maintaining feature has now evolved into Adaptive Cruise Control (ACC), an embedded system that automatically adjusts your vehicle's speed based on the traffic around you. So, whether drivers are on a busy highway or a quiet road, ACC ensures a smoother, more responsive drive.

The National Safety Council reports that Advanced Driver Assistance Systems (ADAS) could potentially prevent 20,841 fatalities each year, with lane-keeping assistance playing a significant role by potentially saving 14,844 lives on its own.

Here, we highlight the key embedded system technologies of Adaptive Cruise Control in more detail:

• Radar and Lidar Sensors - These sensors detect the distance and speed of vehicles ahead, enabling the system to adjust speed dynamically.
• Embedded Processing Units - Process the data from sensors in real-time to make quick decisions on acceleration and deceleration.
• Vehicle-to-Vehicle (V2V) Communication - Enhances ACC by allowing cars to communicate with each other, further improving traffic flow and safety.

2. Anti-lock Braking System (ABS) Controller

When it comes to safety, there's no room for compromise. The Anti-Lock Braking System (ABS) is a prime example of how embedded systems can make driving safer. The ABS controller kicks in during sudden braking to prevent wheel lock-up, allowing you to maintain control of your vehicle. It’s this kind of innovation that makes embedded systems essential in critical moments.

Take a look below for more details on the function of Anti-Lock Braking Systems:

• Wheel Speed Sensors - Constantly monitor the speed of each wheel, ensuring that the system can detect and respond to potential lock-up situations instantly.
• Electronic Control Unit (ECU) - Analyzes the data from wheel speed sensors and controls brake pressure to prevent skidding.
• Hydraulic Modulators - Adjust brake pressure independently at each wheel to maintain optimal traction and control during emergency braking.

3. Infotainment System

If you are someone who values connectivity, you’ll appreciate the role of embedded systems in modern infotainment setups. Automotive-embedded systems manage everything from navigation to entertainment, ensuring that your driving experience is as enjoyable as it is efficient. With seamless integration to your smartphone and the cloud, drivers are always connected, whether taking a short commute or a long road trip.

Infotainment Systems have several impressive technical features. Here are a few for you to keep in mind:

• Touchscreen Interfaces - Provide intuitive control over navigation, media, and vehicle settings, making it easier to access features on the go.
• Bluetooth and Wi-Fi Connectivity - Allow for seamless integration with smartphones and other devices, enabling hands-free communication and streaming.
• Voice Recognition Software - Enables hands-free operation of navigation, calls, and media, contributing to safer driving by reducing distractions.

4. Engine Control Unit (ECU)

While many people focus on visible tech, the real magic often happens behind the scenes. The Engine Control Unit (ECU) is a perfect example. The ECU manages and optimizes engine performance, ensuring that fuel consumption is efficient, emissions are minimized, and streamlined functionality. 

Some of the most influential embedded systems technologies that drive the function of an Engine Control Unit are as follows:

• Microcontrollers - These form the core of the ECU, processing data from various sensors to manage engine functions in real-time.
• Sensor Networks - Gather data on temperature, pressure, and other variables to feed into the ECU, allowing for precise control of engine parameters.
• Real-Time Operating Systems (RTOS) - Ensure that the ECU can handle multiple tasks simultaneously without lag, critical for maintaining engine efficiency and performance.

5. Electronic Stability Control (ESC) System

Yet another crucial player in vehicle safety is the Electronic Stability Control (ESC) system. The ESC system uses embedded technology to help drivers maintain control during sudden manoeuvres, especially in tricky driving conditions. By making real-time adjustments to the brakes on individual wheels, ESC helps prevent skids and accidents and keeps the vehicle on track.

Curious about how an ESC System works? Take a look below at the key technologies that contribute to overall operation:

• Yaw Rate Sensors - Measure the rotation of the vehicle around its vertical axis, helping the system detect loss of control.
• Accelerometers - Detect the vehicle’s acceleration in different directions, providing data to the ESC for stability corrections.
• Brake Actuation Modules - Work with the ESC to apply brakes to individual wheels as needed, enhancing vehicle stability and preventing rollovers.

How Does the Change to Electric Vehicles Impact Embedded Systems?

According to research, The global electric vehicle (EV) market, valued at £291.5 billion in 2023, is expected to more than double, reaching £714.9 billion by 2030.

With EVs expected to account for 46% of light-vehicle sales by 2025, growing to 83% by 2035, there is no question that the industry is expanding at a rapid pace as businesses race to adapt embedded systems technology to support this move.
