We are living in an era of technological evolution; the automotive industry has also been transforming, like any other modern technology. Self-driving smart cars are not science fiction anymore. Here, we will see the applications of wireless technology in smart vehicles.
Since the advancement of modern communication technologies, every industry has adapted to modern wireless transmission techniques to support a wide range of possibilities. Modern wireless technologies enable us to enhance safety, security, efficiency, and convenience.
How wireless technologies are used in the automotive industry
Infotainment system
It has been a few decades since the first generation of car audio systems became available in the market. Ever since the introduction of the first-generation audio cassette players, car audio systems have gone through a continuous evolution.
Compact discs replaced the old generation magnetic tape players. A few years later, DVD and Blu-ray discs were introduced. The latest models of car multimedia systems are capable of handling HD audio and video formats.
What is the role of wireless technologies in infotainment systems?
We are able to connect our Smartphones and other smart devices to our infotainment systems using wireless technologies like Wi-Fi and Bluetooth. Users can pair their devices with infotainment systems; it can respond to voice commands, handle hands-free mode to answer calls while driving, and operate systems with ease and convenience.
In the future, high-definition multimedia players will be common in every vehicle.
Accurate mapping of vehicles is critical for autonomous driving. Modern wireless communication technologies enable us to locate precisely and transmit information with considerably low latency. The collected information can be used for efficient navigation and sharing with other nodes.
Modern navigation applications can be integrated into the infotainment systems; this will allow users to navigate using GPS/GLONASS systems easily.
Smart cars can communicate with modern communication networks like LTE and LTE Advanced. Supercharged 5G network and the Internet of Things will offer effective management of smart driving.
Everything connected is a modern concept in the automotive industry, where vehicles will be connected to almost every physical thing in their surroundings and to the cloud.
Connected car concept – Autonomous driving
Self-driving cars have a system of sophisticated software, well-designed hardware, and low-latency connectivity. A wide range of sensors, like LiDAR, RADAR, Sonar sensors, cameras, and radio antennas, are used in self-driving cars.
Integration of these sensors and processing of real-time data with higher accuracy is required for the implementation of a smooth cruise of vehicles. Each of the sensors has a specific purpose, and it will continuously collect large amounts of data.
Using complex software algorithms, collected data is processed, and each decision is made accurately (whether to speed up, slow down, make turns, or stop the vehicle, etc).
Using 5G networks, huge amounts of data can be handled, and a large number of vehicles can be connected to the network. Low-latency signals are significant for improving the accuracy of path detection and decision-making for vehicles (using algorithms).
With Vehicle-to-vehicle communication (V2V) technology, vehicles can exchange information like the distance between two vehicles, traffic information, road conditions, etc. This information can be used to manage and control traffic efficiently during heavy traffic conditions.
Vehicle-to-vehicle (V2V) communications system offers line-of-sight and non-line-of-sight collision avoidance systems, which help drivers share the road. It offers a larger scale of safety for passengers.
Vehicle to Infrastructure (V2I) communications system allows communication with many safety applications, digital sign boards, transfer location information, and cellular long-range communication to share information regarding traffic conditions and reduce congestion.
Vehicle-to-Pedestrian (V2P) communication systems can detect the presence of people in the surroundings even when the driver can’t see them directly and alert drivers, pedestrians, motorcyclists, and bicyclists using special smartphone applications.
Vehicle to Cloud (V2C) communication deals with security authentications, sharing information about parking lots, reserving lot positions, and keeping updated with the latest device firmware.
Automatic alerts of emergencies can be activated during accidents. It will speed up rescue operations, recovery, and clearing of motorways.
Wireless charging of vehicles
Wireless electrical charging of vehicles is a hot topic in the automotive industry. Technology pioneers like Qualcomm have already developed efficient wireless charging technology for cars. Quick wireless charging offers convenience for users to efficiently charge their vehicles at wireless charging stations, parking lots, or at home.
Qualcomm has achieved transfer efficiency of more than 90% with a single primary base pad. Wireless charging technology can be further improved for better efficiency and easier implementation in the future.
Vehicle security
Security is one of the most significant aspects manufacturers should consider. Keyless access is a convenient feature of any vehicle; an automatic alert during theft is an added security option for modern vehicles.
Internet of Things applications
Smart sensor technology, together with the Internet of Things, will offer an effective management of inventory, service, and repair schedules of future vehicles. Smart cars will have a wide variety of sensors designed for specific applications. It detects the condition of a spare, triggers a service provider, and arranges a schedule for maintenance.
Conclusion
The possibilities of wireless technology are limitless, and many tests are in progress to support autonomous driving, connected vehicles, and smart car technologies. Wireless robots are deployed in manufacturing plants to support production and increase efficiency and precision. Effective use of modern wireless technologies integrated with automobiles will offer a much more convenient and safer road trip in the future.
