red net news reporter long qi and correspondent luo xi reported from zhuzhou
vehicle information, battery power, motor temperature... various data are constantly jumping on the system display screen. the running tracks of all buses of crrc times electric vehicle co., ltd. (hereinafter referred to as "crrc electric") are clearly visible on the display screen.

on the morning of september 25, at the crrc electric yunzhitong big data cloud vision center, the reporter saw a powerful monitoring network. relying on "beidou + electric vehicles + big data", "yunzhitong" monitors each crrc electric vehicle in operation in real time, making travel more "smart".
wen jianfeng, deputy director of crrc electric technology center and deputy general manager of changsha zhiyu new energy technology co., ltd., said that "yunzhitong" creates files for each bus, tracks and records the use and maintenance status of the vehicle, and monitors the safety status of the vehicle. "it can calculate and analyze, helping customers to accurately manage energy consumption."
crrc electric has been engaged in the research and development of internet of vehicles and on-board terminals since 2014, which has been more than 10 years. it has accumulated a large amount of vehicle data, including positioning data and internet of vehicles data.
as of now, crrc electric has more than 40,000 vehicles in operation, and the accumulated vehicle data is as high as 1tb every day. since 2019, crrc electric has begun to introduce beidou positioning for vehicle positioning.
for example, crrc electric has the full-stack design capabilities for t-box from circuits, structures, to software, and has created a number of independent t-box products.
crrc electric micro-circulation minibus.
among them, the beidou-based combined positioning products are applied to 5.3-meter self-driving minibuses, 10-meter-12-meter self-driving buses, 18-ton sweepers, electrified roads, etc., to solve the positioning problems in obstructed scenes; the beidou-based timing service is applied to self-driving vehicles to achieve synchronization of original perception data and time synchronization of each controller.
crrc electric's high-precision positioning is mainly used in intelligent driving vehicles. currently, intelligent driving is centered on decision-making control platforms and algorithms, integrating perception system components (including high-precision positioning) and actuators to develop complete vehicle series products, breaking through application scenarios such as public transportation, minibuses, and sanitation cleaning. currently, more than 100 products have been promoted.
it is worth noting that crrc electric has transplanted core technologies such as rail transit traction transmission, vibration and noise reduction, ergonomics, and energy management into the field of new energy vehicles, creating its own core technology t technology.
wen jianfeng introduced that the t technology platform is centered on digital vehicle architecture + advanced power system, and is a technology integration platform for safety, energy saving and reliability of new energy commercial vehicles. it is currently iterating to the seventh generation.
among them, the digital vehicle realizes the full life cycle management of the vehicle based on the smart internet of vehicles platform, builds a three-in-one vehicle networking system of the vehicle side, cloud side, and data side, empowers the vehicle's intelligent networking attributes, enables operations managers to easily manage, drivers to gain a sense of driving accomplishment, and maintenance personnel to achieve efficient maintenance.
