Communication technology changes dramatically, refreshing the car driving experience

When the phone first came to market, few people foresee that this small device can bring such revolutionary changes to people's lives. With the revolutionary leap to smartphones, mobile phones have become a mini-computer that provides connectivity to almost everything we do. Nowadays, the advanced technology that the communications industry continues to introduce has paved the way for the automotive design industry to achieve the same great changes.

Bluetooth open circuit

A few years ago, the car you were driving can take you from point A to point B. You can only connect to the outside world via radio or mobile phone. With the advent of Bluetooth technology, hands-free communication has emerged – a technology that has been proven to save lives. Today, low-power Bluetooth Smart technology is driving the explosive growth of wireless applications, including wearable technologies that capture and transmit biometric data. If the wearable technology is used in a car, it is possible to warn drivers who are driving dangerously, such as dozing, according to key indicators such as glucose level, blood pressure or blood alcohol content, to remind them to take measures in advance to avoid dangerous accidents.

Wi-Fi extension possibilities

Another important component of connected cars is Wi-Fi technology, which enables cars to synchronize networks without the need for cell phone signals. Wi-Fi technology enables manufacturers to provide software and feature updates directly to the car. Drivers can remotely unlock their vehicles using smart mobile devices and Wi-Fi applications, activate climate control systems, and help owners find their cars in crowded parking lots. At the same time, Wi-Fi technology can also be used to check the amount of oil or electric vehicle. The same device can also receive performance reports and diagnostic warnings sent directly by the car.

For many users, what's even more exciting is the introduction of Gigabit Wi-Fi or 5G Wi-Fi technology, which enables seamless media streaming performance for mobile device content delivery to in-vehicle infotainment systems and rear-seat displays. The technology also makes it possible to establish a high-speed Internet connection directly from Wi-Fi hotspots: “How about watching movies in the car?” Wi-Fi has become a vehicle-changing technology that changes the rules of the game. Analysts predict Wi-Fi based on Wi-Fi. Technology's automotive applications will grow eightfold in the next five years.

Car Ethernet point-to-point connection

From simple fuel injection to advanced engine systems, driver assistance systems, airbags, safety systems, infotainment systems, tire pressure monitoring systems, and safety aids such as rearview mirrors and radars, we have witnessed a revolution in in-vehicle electronic systems. . But true connected cars need more than just these isolated technologies. Achieving this deeper level of capacity to connect smartphones to in-vehicle infotainment systems requires a network protocol that is fast and scalable to faster, more adaptable, and more cost-effective. More importantly, it also needs to provide the highest level of protection against failures and virtual attacks.

The most logical choice is the interconnected ancestor Ethernet technology, but the need to remove those large, heavy cables. To this end, the talented developers in the automotive and electronics industries have come together and hope to solve this problem together. In the end, they introduced 100 Mbps high-speed Ethernet technology, which is connected by lightweight, inexpensive cables and optimized for vehicle applications. Car Ethernet provides everything needed to connect cars, turning the entire car into a centralized, secure data center with proven performance, compliance and security.

From elite to mass

In the next decade, only the features that are available in luxury cars will be applied to ordinary economy cars. Ethernet has been applied to the road as a backbone network technology that seamlessly collaborates with in-vehicle protocols and wireless technologies for advanced performance and security needs. And because personal mobile devices can seamlessly connect with any car, including private cars, spouse cars, or rented cars, the problem of device associations will no longer exist. Manufacturers will continue to take advantage of Ethernet's performance and cost advantages to introduce more security features for all types of vehicles, such as rearview cameras, panoramic parking assist systems, lane departure warnings and collision avoidance systems. Lightning synchronization and streaming capabilities will transform the connected car into a “living room on wheels” that offers dazzling information and entertainment features. And yes, the automotive industry has been keenly aware of the danger of driver distraction. So in addition to interconnectivity, we are also expected to see an optimized voice activation system and an overhead display mounted in place to ensure that the driver always holds the steering wheel and keeps the eye in front of the driving state.

Extend from in-vehicle applications to road applications

Once these technologies are tightly integrated with automotive applications, developers can focus on solving the headaches of highway safety. The industry is also researching vehicle-to-vehicle (V2V) communication technology, which enables dynamic wireless data exchange between your car and other vehicles. Providing 360° identification information for other vehicles based on orientation and speed, an anonymous exchange of data like “I am coming” will revolutionize the way we drive our roads. Drivers can rely on this sensed data stream to determine the imminent danger and take action in advance to avoid accidents. In addition, there is automotive-to-infrastructure (V2I) technology, which enables communication between the car and the road infrastructure, enabling intelligent traffic signals, automatic toll stations and automatic car rental.

New driving experience

We live in a world of increasing connectivity. Analysts predict that by 2025, all new cars sold will be networked, which will surely redefine the driving experience for customers and create a new era of choice.
