As intelligent in-vehicle interaction scenarios continue to evolve, digital car keys are enabling smarter user experience such as seamless welcome, automatic unlocking, and walk-away locking, significantly enhancing everyday convenience. With outstanding device compatibility, stable connectivity, and a well-established ecosystem, Bluetooth LE has become a core communication technology for digital car keys. Compared with traditional key solutions, Bluetooth LE-based digital car keys offer advantages such as more reliable connections and lower power consumption.

Goodix automotive-grade Bluetooth LE SoCs are AEC-Q100 Grade 2 certified and deliver high reliability, high performance, and exceptional stability to operate with ease in complex and demanding automotive environments. Goodix also provides complete Bluetooth LE digital car key hardware and software reference designs, helping customers significantly reduce development complexity, shorten time to market, and accelerate product commercialization. Up to now, Goodix solutions have achieved high-volume mass production with multiple Tier 1 suppliers and OEM customers, earning broad recognition for the performance and reliability.

Powered by Bluetooth LE technology, tire pressure monitoring systems (TPMS) are becoming a mainstream market solution thanks to advantages such as low power consumption, strong interference immunity, two-way communication, and intelligent integration.

The Goodix TPMS solution, based on Goodix automotive-grade Bluetooth LE SoC, supports two-way communication and OTA, enabling real-time acquisition of key data such as tire pressure and temperature to deliver around-the-clock dynamic monitoring and anomaly alerts for enhanced driving safety. The solution also offers low-power advantages that help extend device service life and meet the mass production requirements of passenger vehicles and new energy vehicles. In addition, Goodix provides mature supporting hardware and software reference designs to help customers accelerate development and high-volume production.

Amid the ongoing trend toward lighter and more highly integrated new energy vehicles, wireless battery management systems (wBMS) based on the Bluetooth LE technology are emerging as a key direction for next-generation power battery upgrades. This solution enables real-time wireless transmission of battery module data and accurate acquisition of critical parameters such as voltage, current, temperature, and state of charge. It also supports status monitoring, cell balancing, and safety protection, while simplifying wiring harness architecture, reducing vehicle weight and cabling costs, and improving system integration, safety, and driving range stability.

Goodix automotive-grade Bluetooth LE SoCs are designed to operate reliably in complex automotive environments, including extreme temperatures and electromagnetic interference, providing highly reliable and high-performance communication support for wBMS. Backed by mature integrated hardware and software reference designs, Goodix helps customers simplify development, improve R&D efficiency, and accelerate the deployment of new energy vehicle battery management solutions, empowering vehicle lightweighting and energy efficiency upgrades.

As vehicles become increasingly intelligent and connected, they are rapidly evolving into mobile smart spaces. Built on Goodix automotive-grade Bluetooth LE SoCs, the solution enables seamless in-vehicle networking for IoT devices throughout the cabin, supporting convenient interconnection of devices such as ambient lighting, in-vehicle refrigerators, mosquito-repellent lamps, remote controllers, and camping lights. This helps simplify the management of in-cabin devices while enhancing driving and passenger lifestyle experience. With advantages including low power consumption, high stability, easy networking, and readiness for mass production, the solution has become an important choice for full-domain in-vehicle wireless connectivity.

For external connectivity, leveraging Bluetooth multi-connection networking capabilities, the solution can also optimize the connection and control of internal vehicle sensors, while enabling interoperability with external devices such as charging piles and parking locks.
