Foreword
Connectivity technology has evolved around our commonly used mobile phones / smartphones and tablets. Recently, not only in mobile phones / smartphones, but also in digital cameras, household appliances, game consoles, healthcare equipment and automobiles as long as they are mechanical devices. Murata puts forward the slogan "Connect the world happily with connectivity technology!" And proposes and strives for various connectivity technologies. In the following, we focus on Murata's efforts for vehicle-mounted connectivity technology.
Murata's vehicle connection module
Murata's in-vehicle connection modules already have Bluetooth modules equipped with car navigation and car audio systems around 2003. These modules are wirelessly connected via Bluetooth via mobile phones or portable music devices carried into the car, enabling hands-free and music playback and other functions, and contributing to the convenience of drivers without hindering safety.
In addition to the hardware part of Bluetooth that guarantees wireless performance, Bluetooth module also has built-in hands-free, music playback, phone book transmission and other commonly used software. In other words, this software also includes the driver's voice recognition function without affecting the safety performance, the echo cancellation / noise reduction (EC / NR) function to improve sound quality, and the interconnection with various types of target devices. Sexual function.
Recently, the development and commercialization of combination modules of new wireless systems, such as W-LAN function, GPS function, and NFC function, have been added to Bluetooth (Figure 1). Especially the W-LAN system, which is the most anticipated system for in-vehicle connection in the future. We will make use of Murata ’s rich connection for consumer devices? The experience and achievements in the module provide driver migration, system performance evaluation, various Full support for certified software. (figure 2)

Murata's in-vehicle connectivity modules have sold more than 13 million cumulatively as of December 2012, and are installed in cars around the world.
Requirements for automotive products and Murata's efforts
Compared with general consumer devices, cars have a longer service life and a harsher environment. Moreover, the car is a device related to life and property safety, so of course its requirements will be very strict.
However, in-vehicle connection modules require not only wireless functions and performance, but also high / long-term reliability, long-term supply, and continuous quality improvement (zero defects). Therefore, it is important to develop technology, evaluation technology, and manufacturing technology to meet such requirements and conditions.
After having an excellent product design, it is very critical to have high-quality performance and ensure continuous and stable manufacturing technology. At present, all Murata connectivity modules, including those used in vehicles, are produced in our company's factories. Therefore, we can ensure the quality of vehicles that have been determined from the initial stage of development. The production process of in-vehicle connectivity modules is basically similar to that of consumer equipment modules. If you want to separate from the production line, there is a special in-vehicle product production line, which is produced on this special production line. In order to achieve on-board quality, the in-vehicle product special department arranges the staff who have obtained the data management and worker certification system qualifications to perform operations, and also intervenes in special inspection projects, traceability organizations, through these means to achieve the basic of automobile product manufacturing Idea-zero defects.
It can be seen that in the future, connectivity technology will be gradually put into new wireless systems and new applications and will continue to expand. Connectivity technology for vehicles will also become multifunctional. But I think no matter how the product changes, the concepts and efforts for vehicle-mounted vehicles described here will not change. I think whether it is possible to use the car concept as the basis to carefully and step by step focus on quality ultimately determines the quality of the quality.
Future connectivity technologies for in-vehicle use
Connectivity technology will become one of the key technologies supporting the evolution of automobiles in the future. The following will list some possible scenarios in the future. Nowadays, the use of Bluetooth is mainly based on sound and driving. The standard for installing the W-LAN function in smartphones that has recently exploded has begun, and this function has also been added to in-vehicle devices, enabling smartphones with W-LAN systems Interconnection becomes possible. Therefore, the external network and smart phone in the hotspot can be controlled and used by the vehicle-mounted device. You can also play animations at the same time.
Among other short-range wireless systems, BLE (Bluetooth Low Energy) and NFC (Near Field Communication) systems have also received much attention. These communication systems will also be listed as standard equipment for smart phones in the future. For example, the personal mobile phone will become his car key, and the lock will only be unlocked when the driver is close to the car. The position of the handle and seat can be set according to the individual.
NFC is a technology used in "Mobile Wallet" and "Mobile Suica", so it is currently considering pairing with Bluetooth and W-LAN in the car. The above is mainly the content of the use of infotainment systems, and the use of vehicles and networks, vehicle-to-vehicle, road-to-vehicle communication to relieve congestion and safety support is also being studied. Expansion of cable harnesses and other issues may be resolved in the future.
From the infotainment system in the car to the "walk, turn, stop" safety car has a wide range of uses. Relatively high reliability is necessary. A further breakthrough in safe wireless is also necessary. It can be said that in-vehicle connectivity technology has infinite potential.
Conclusion
Murata, with the slogan "Connect the world happily with connectivity technology!" As its slogan, is committed to a variety of wireless systems and makes proposals for connection technologies for various devices in the world. These will also become the basic technology of the in-vehicle connectivity technology in the future. In the future, we will provide the best vehicle-mounted connection solutions in the market in the near future. In the near future, while introducing various sensors, we also want to propose that it can be held by other companies that have been used in customers' cars. The technology, the product combines the attractive overall solution.
