Do you still remember the Google AI (Artificial Intelligence) AlpaGo that was in the limelight this March? It is AlphaGo, with a “brain” that can thick and learn, who completely defeated the South Korean Go master Li Shishi representing human being.
Now, “the best brain” of new energy buses has come! It is the flagship product – Yunzhitong, which CRRC TEV has successfully developed after 3 years of painstaking efforts. It can compute, analyze, has strong ability to learn and thick, and even can realize automatic driving!
This is not boasting! As the editor, I will now show you its “intelligence”
“Central Guard Bureau” – Protection God for Vehicle Safety
During the operation of the vehicle, Yunzhitong will, in real time, continuously and automatically collect the status data of BMS, motors, controllers and battery, judge the safety status of these key parts by automatic calculation and analysis, can actively take safety measures once it detects abnormal vehicle status, and can also automatically send an alarm to users by email, APP and external system, so as to avoid vehicle running “with illness” and effectively ensure vehicle safety. For example, when the battery has abnormal temperature or voltage, Yunzhitong can order the battery management system to automatically cut off power supply and heat source, as that a battery fire accident can be prevented from its origin.
Moreover, Yunzhitong can also monitor in real time the driving operations of drivers, record and correct the drivers’ driving behaviors. For example, drivers always forget to close the door after starting the vehicle or they drive the vehicle with door open. The reminding and monitoring of Yunzhitong can help drivers avoid these kinds of behaviors that are against regulations, so the vehicle operation safety is effectively improved.
“Housekeeping Wife” – Improve Energy-Saving to the Maximum
How to make the new energy bus improve energy-saving to the maximum and be a good diligent housekeeping “wife”? Through double-mode positioning of GPS and BeiDou system plus the access to traffic information data, Yunzhitong can analyze in real time the location and speed of the vehicle, traffic congestion situation, traffic light status and ramps, adjust in real time the energy distribution and control strategy of the vehicle according to these big data, making every drop of fuel and every kWh of electricity have their best efficiency and refusing ineffective energy consumption (e.g. in case of waiting, going downhill and traffic congestion, implement intelligent engine shutdown, automatic power reduction of drive motor, and automatic power reduction of auxiliary motor for vehicle operations).
Besides the technology itself, the operation habits of drivers are also every important. Let’s have a look at the comparison data: Take the 12 meter plug-in bus on a bus line in Changsha city as an example. By correcting the driver’s behaviors with Yunzhitong, the average fuel consumption is reduced by about 5% compared with that before the use of Yunzhitong, on average saving fuel consumption expenditure by almost 6,000 yuan every year.
The secret is that, Yunzhitong can collect the driving behavior data (e.g. rapid acceleration and deceleration, parking air-conditioning, and coasting) during the whole process of vehicle operation, evaluate, analyze and conclude the driver’s behaviors and habits through a cloud platform, and present the result by means of diagrams and report forms, making the driver clearly see the relationship between the driving behaviors and energy consumption, so as to realize the reduction of energy consumption by regulating driver’s behaviors. Meanwhile, users can set the ratio between parameters and marks for every evaluation point according their own needs, personalizing evaluation rules.
“Super Housekeeper” – Carry Intelligence through to the End
Some customers may say that they already have their own management platform, isn’t “Yunzhitong” a repetition? That is actually not the case. “Yunzhitong” doesn’t conflict with the customer’s own management platform. On the contrary, it is a system that can make your management platform more powerful and intelligent and achieve intelligent interconnection with their management platform. Through “Yunzhitong” system, customers can achieve full intelligence in vehicle scheduling, line layout, vehicle maintenance schedule, charging, etc.
Based on the knowledge of “Yunzhitong” about the real-time distribution and status of vehicles, the vehicle fleet can also deploy the transport capacity more properly and improve the utilization rate of its vehicles. During the monitoring by “Yunzhitong”, when the wearing parts of vehicles arrive at replacement cycle or need maintenance, the system will inform the user in advance, so that the vehicle fleet can properly arrange the time for maintenance and care, avoid the line operation being affected.
Moreover, “Yunzhitong” platform can realize intelligent charging. While collecting and analyzing vehicle information, it can open the data channel of the charging pile, obtain the location, model and charging status of the charging pile, and in combination with navigation and payment services, construct an intelligent charging loop, so as to greatly improve the operation efficiency of users of pure electric vehicles.
“Gold Brain” – A platform that can be updated without limit
“Yunzhitong”, a gold brain, can be updated, developed and interconnected without limit. Besides being interconnected to CRRC TEV after-sales service terminal and bus company management terminals, the system can even be interconnected to government regulation platform and more related management platforms. In the big data analysis, “Yunzhitong” can be updated and developed continuously, so more functions can be achieved. For example, through big data analysis, the health condition and after-sales quality of every vehicle can be obtained. “Yunzhitong” can also intelligently collect traffic information, so as to “customize” the new energy vehicle for the customers to the maximum extent.
The release of CRRC TEV “Yunzhitong” is like the delivery of clairvoyance and a competent housekeeper for users of new energy buses. Within just 1 year after the system was put in use, it has received wide attention and praise from the markets. Currently, “Yunzhitong” system has connected almost 4000 vehicles into the network, and has successfully helped 56 bus companies achieve their goals for improving efficiency and reducing energy consumption.
