What is the RTM system in automobiles?

Real-time Monitoring (RTM) is a new national standard requirement by the Ministry of Industry and Information Technology (MIIT) to ensure the safety of New Energy Vehicles (NEVs). The RTM system sends real-time vehicle data to enterprise and government backends in accordance with G/BT32690 requirements. Purpose of RTM: A system for real-time monitoring of operational data from new energy vehicles, which is transmitted to a backend database via OCU3. Function of RTM: Before an accident or malfunction occurs, the RTM system can detect it and alert the user. When a user's vehicle is in danger, the backend database reports to the call center, which then contacts the customer to inquire if assistance is needed. The call center then connects with the dealership to help the user, either by arranging for the user to visit the dealership for repairs or by dispatching the dealership to the scene for rescue.
I understand that by 'car RTM' you probably mean the real-time monitoring system. This thing is widely used in smart cars to monitor various vehicle data in real time, such as engine temperature, tire pressure, battery status, etc. It's most useful when driving on highways - it might suddenly alert you that the left rear tire pressure is low, forcing me to quickly find a service area for inspection. Some premium models even feature cloud transmission, allowing mechanics to remotely view fault codes. Last week when my check engine light came on, this system helped detect a faulty coolant sensor in advance, preventing a potential breakdown. Nowadays even domestic cars priced around 100,000 yuan come standard with this feature. I recommend having mechanics check the module wiring during maintenance, especially in rainy regions where connector oxidation is common.
I reckon the RTM in cars is that remote diagnostic system. Last winter when my car suddenly wouldn't start, the mobile app immediately alerted me about low battery voltage. This system actually connects to the OBD port, transmitting engine data to the cloud where manufacturers can analyze driving habits. It's most reassuring on long trips - refreshing oil temperature every ten minutes, once even warning me about an overheating turbocharger in time. When buying used cars, be careful: modified audio systems often mess up these wiring circuits. Nowadays EVs rely more on this, especially for battery health monitoring - my friend's EV used it to replace problematic battery cells preemptively. Though privacy concerns exist, the safety benefits are significantly higher.
