Texas Instruments' new technology opens up new ways of communicating with smartphones and cars

In general, the driver pairs the smartphone with the car via a Bluetooth connection to make a call or listen to music. The connection between these is the typical Bluetooth technology, and the newly released SimpleLinkTM CC2541-Q1 uses Bluetooth Smart, also known as Bluetooth low-power technology, which only needs to consume a small amount of energy from the car battery. It can bring endless possibilities for in-car settings.

The next generation of cars with this new Texas Instruments product can unlock or lock the car remotely from an app on your smartphone. Or when a friend wants to borrow a car, the owner only needs to send a code to his friend's smartphone, and there is no need to give him the key. In the car, the seat position and ambience settings can be automatically adjusted based on the user's smartphone settings. The surrounding lighting in the car can be adjusted to any color the driver wants, and all operations can be done through the smartphone app. During the driving process, if the engine check light on the dashboard lights up, the car can immediately report the problem and solve the problem to the driver's smartphone.

The SimpleLink CC2541-Q1 also allows different parts of the vehicle to communicate with one another in a variety of ways. Bluetooth Smart technology enables automakers to eliminate some wiring and reduce the cost and total weight of the car, which ultimately improves fuel economy. Interconnect technology can be used in any scenario where a small amount of data needs to be transferred between different parts of the vehicle.

Joel Zolnier, global business development manager for low-power RF automotive and medical applications at Texas Instruments, said: "The fuel economy is becoming more important, and fuel economy is highly dependent on the weight of the vehicle itself. Some people may not know, for Wiring and slings that secure a variety of cables are the heaviest components of all types of cars."

Bluetooth Smart will be used in cars, trucks and SUVs in the near future, when drivers can control more vehicle settings with their fingertips on their smartphones while improving fuel economy and reducing costs.

Joel said: "There are some limited use cases, and they will be fully operational in the next one to two years. In a few years, I believe we will increasingly use Bluetooth Smart technology in cars."
