A brief discussion on the application of RTC clock in smart cockpit

With the development of technology, more and more in-vehicle electronic devices are emerging. In order to provide drivers and passengers with a better experience, smart cockpits have come into being.

Updates and iterations of car cockpits: The first generation was relatively simple, with a car radio and tape player, providing users with simple entertainment functions such as radio and music. The second generation added more electronic products, including a central control screen, a car system, and a navigation system to provide convenience for users' travel. The third generation introduced intelligent technology, including a larger central control screen, an LCD instrument panel, HUD (head-up display), a streaming media rearview mirror, etc., as well as in-car audio, seats, lights, displays and other equipment, providing users with human-computer interaction, visual perception, and richer entertainment functions. Main components of the smart cockpit: The smart cockpit consists of three parts: hardware (instrument panel, streaming media rearview mirror, HUD, central control screen, rear seat entertainment system, air conditioning, seats, audio, etc.), software, and human-computer interaction (voice, face, touch, gesture, biometrics, etc.), integrating T-Box, DMS system, ADAS system, high-precision positioning system and future V2X, providing users with a more convenient, intelligent, warm and comfortable experience.

Typical functions of smart cockpit

With so many functions in the smart cockpit, problems such as high energy consumption and safety of the system will inevitably arise. How to reduce energy consumption and ensure safety is one of the primary issues facing automakers. Therefore, automakers hope to reduce energy consumption as much as possible while maximizing energy utilization through power management systems. Based on the intelligent operating system of the car, there needs to be internal operation logs and diagnostic data to present information to customers in real time, so that users can understand the vehicle condition in real time and solve problems quickly. For this reason, the smart cockpit system needs to use multiple high-precision, high-reliability, miniaturized, and low-power real-time clock chips (RTC). Functions of RTC in the smart cockpit:

Energy consumption management: When the smart cockpit enters sleep mode, the RTC keeps working normally and wakes up the main system periodically through the timing function, thereby reducing the energy consumption of the system.

Safety management: RTC provides high-precision timestamps for event recording, system operation logs, power consumption, mileage calculation and other functions to ensure the safety and reliability of the entire vehicle system.

Comfort experience: RTC provides accurate time for car instruments, central control display, entertainment system, etc., providing drivers with convenient, diverse functions and comfortable experience.

Dapu Communication has been focusing on the research and development of high-stability clocks for nearly 20 years. It also has rich experience in chip design and is committed to closely integrating high-stability clocks with semiconductors. It has launched a number of high-precision, wide temperature range, low power consumption, miniaturization, fast startup, and high shock resistance high-performance RTC chips that can meet the differentiated needs of different application fields. It has passed the certification of multiple industry leading customers and entered the list of high-quality supply chains.

For automotive intelligent cockpit, instrument, central control and other subsystems, Dapu has specially launched:

At the same time, the company has also launched a full range of clock products for new energy vehicles, including: Crystal, SPXO, TCXO, Buffer, etc. The diversified products facilitate users to select and combine, providing a "one-stop" solution.
