The concept of a built-in RTC (Real-Time Clock) refers to a timer or clock device built into a device or system to generate a timestamp. RTC is commonly used in embedded systems, computer motherboards, network devices, etc.
The main function of RTC is to provide information about the current time, which is critical for many applications, such as: network communication, logging, event triggering, scheduling tasks, etc. RTC can provide accurate time stamps while the device is running to achieve a variety of scenarios that require time synchronization.
In computer networks, RTC is also used in the Network Time Protocol (NTP) to enable devices in a network to synchronize their time. This helps ensure consistency and accuracy in data transmission. In vehicles, RTC is widely used in various systems to provide time and date information for vehicles to support vehicle navigation, entertainment, safety, diagnostics and other functions.
In addition to being a component of in-vehicle communication and autonomous driving systems, RTC also provides basic functions for several other systems. For example, automotive central control, instrumentation, audio, smart cockpit, on-board T-box, battery management system (BMS), driver monitoring system (DMS), smart Bluetooth key, etc., may require the assistance of RTC.
Specifically, RTC can be used as one of the wake sources of the BMS system, triggering the BMS to manage its working mode (sleep, run, etc.). It is also an input condition to the SOC's battery management algorithm, which can be modified periodically. In addition, RTC can also provide accurate calendar time, providing time coordinates corresponding to historical data and fault information for BMS.
In in-vehicle networks, RTC may also help with time synchronization capabilities to support real-time monitoring and control of vehicles.
The timing accuracy is 5s/24h, which usually means that the device has a timing accuracy of less than 5 seconds per day. This kind of high-precision time calibration usually requires the use of some form of high-precision RTC (Real-Time Clock) or similar device, which can provide a very accurate time stamp, usually provided by atomic clocks or GPS, etc.
Timing with this precision is crucial for many applications, such as in computer networks, where the time of all devices needs to be synchronized to ensure data consistency and accuracy. In addition, in on-board Ethernet, this high-precision timing can also be used to achieve a variety of scenarios that require time synchronization, such as monitoring and controlling the running state of the vehicle, monitoring the battery management system, and so on.
