When you think of cutting-edge car technology, self-driving cars or solid-state batteries might come to mind. However, there's another crucial innovation happening inside your vehicle—one that often goes unnoticed but is essential for making your drive smoother and smarter: in-vehicle communication.
This communication technology powers everything from seamless infotainment experiences to advanced safety systems, all while integrating with charging infrastructure to help you keep your EV powered on the go. It’s the invisible glue that connects the parts of your car, and the companies making it happen are nothing short of revolutionary. From Google Auto to major OEM (Original Equipment Manufacturer) systems, let’s dive into who’s leading this digital dialogue, the protocols that make it work, and how charging station data is making its way into your EV.
One of the major names in the world of in-vehicle communication is Google, primarily through its two platforms: Android Auto and Android Automotive OS. Android Auto connects your smartphone to your vehicle’s infotainment system, offering hands-free control over navigation, music, and communication. It’s essentially an extension of your phone into your car's dashboard. Similarly, Apple CarPlay provides iPhone users with an easy, hands-free way to access navigation, media, and communication through their car’s infotainment system.
On the other hand, Android Automotive OS is a fully integrated, built-in system that runs directly on the vehicle’s hardware, providing a more seamless, native experience. Automakers like Volvo and Polestar have adopted this deeper integration to offer drivers a more connected and intuitive driving experience.
Your vehicle's components need to speak the same language, and communication protocols are the foundation that makes this possible. One of the most widely used is the Controller Area Network (CAN), a protocol that forms the backbone of most vehicle networks. It enables real-time data sharing between crucial systems like the engine control unit (ECU) and the braking system, ensuring that your car's most vital functions work seamlessly together.
For vehicles that demand high-speed communication and fault tolerance, particularly in safety-critical areas like Advance Driver Assistance Systems (ADAS), Flexray steps in. FlexRay supports more sophisticated functions, where speed and precision are paramount. As cars become increasingly connected, Ethernet has also started to play a bigger role, enabling faster data transfer across the vehicle’s systems, particularly for infotainment, camera feeds, and external communication. Meanwhile, Media Oriented Systems Transport (MOST), mainly used for multimedia applications, ensures high-speed, smooth data flow for your vehicle’s infotainment systems.
These protocols enable the smooth and harmonious operation of everything from engine control to your in-car entertainment, creating a reliable and efficient driving experience.
While companies like Google and Apple make headlines with their consumer-facing technology, OEMs (Original Equipment Manufacturers) are working behind the scenes to develop their own in-house systems to manage in-vehicle communication. For example, automakers like BMW, Tesla, and Volkswagen have each created their own sophisticated internal networks to handle everything from power distribution to automated driving features.
Take BMW’s iDrive system, for instance. It brings together infotainment, navigation, and vehicle settings into one user-friendly interface, relying on constant communication between the driver and various car components to ensure a seamless and connected driving experience. Tesla, on the other hand, has taken vehicle communication to another level with its Full Self-Driving (FSD) system. Tesla’s network doesn’t just stay within the car; it also communicates with external data sources and other vehicles, an essential capability for autonomous driving. Real-time communication between Tesla vehicles and the world around them is crucial for ensuring safety and efficiency on the road.
For EV drivers, one of the most important aspects of in-vehicle communication is how you can connect to charging stations. Cirrantic is one company leading this charge by aggregating real-time charging data for EV drivers and automakers. This includes crucial details like station occupancy, charging speeds, and pricing—information that is vital for EV drivers when planning long trips. Automakers often integrate this data into their in-vehicle systems, displaying it on the car’s infotainment system or using it to guide drivers to available charging stations. CPOs (Charge Point Operators), such as Allego and ChargePoint, also provide real-time data about charging stations to in-vehicle systems.
This real-time connection between CPOs, automakers, and third-party data providers like Cirrantic ensures that EV drivers always have the data they need to make quick and informed decisions.
As vehicles become more autonomous, connected, and electrified, in-vehicle communication is evolving rapidly. 5G and V2X (Vehicle-to-Everything) communication are just around the corner, promising to take this technology to the next level.
These advancements mean that our cars are becoming more than just a mode of transport, but rather a smart communication hub, constantly interacting with the world around it to provide real-time updates, suggestions, and assistance. As a result, in-vehicle communication will make driving not only safer but also more enjoyable and far less stressful, letting you focus on the fun of the journey.
