Dongfeng Tianlong KX King Edition smart driving tractorThere are two types of tractors equipped with Dongfeng Intelligent Driving System displayed at the conference. The one pictured above is the Tianlong KX version, which is a 4×2 Tianlong KX King Edition tractor. In terms of power configuration, it is equipped with a 580-horsepower Cummins Z13 diesel engine matched with a Yingdong 12T automatic transmission to jointly build a golden integrated power chain. The vehicle is equipped with Dongfeng Dana DF465 rear axle, with an optional main reduction ratio of 3.07/3.42, which is cost-effective and efficient.
In terms of appearance, it has the familiar King flagship shape, but the difference is that the car’s intelligent driving technology content far exceeds our imagination. It has a powerful intelligent brain, its intelligent driving level reaches L2+ level, and reserves L4 level expansion hardware interface. Its intelligent assisted driving function is powerful, which can fully liberate the driver's hands and feet, relieve driving fatigue, while enhancing driving safety and improving operations. Efficiency, let’s learn about it one by one below.
Angular millimeter wave radar sensors located at both ends of the bumperIn addition to all the functions of imported brands such as automatic emergency braking (AEBS), lane departure warning (LDW), front collision warning (FCW) and other intelligent assisted driving functions that meet regulatory safety requirements, Dongfeng smart heavy trucks also have real-life user experience. Starting from the operation scenario, focusing on the complete closed-loop link of "environment-vehicle-people", we have exclusively developed: ① Vertical functions-full-speed adaptive cruise ACC and follow-up start-stop; ②Fuel-saving functions-predictive cruise PCC, intelligent vehicle speed control distance adjustment; ③ Lateral functions - lane centering LCC, lever lane change ILC, automatic lane change ALC, intelligent avoidance Nudge, intelligent navigation assisted driving (NOA) value, and ultra-wide suspension response, blind spot alarm, etc.; ④ Safety takeover function - Driver status monitoring and reminder, takeover request and safe parking, etc.; ⑤ Operation management functions - remote wake-up, remote call, safety management monitoring and many other black technologies. The above functional configurations together constitute the intelligent driving system of Dongfeng Commercial Vehicles.
Rear-facing millimeter-wave radar sensor located on the side of the vehicle bodySupporting the accurate operation of these smart driving functions, in addition to the on-board smart driving computing unit ADCU, there are also 7 high-definition cameras throughout the body and 5 millimeter-wave radars located on both sides, center, and rear of the bottom of the front face, as well as on the top of the cab. With the precise operation of laser radar and other car-level "clairvoyance" and "wind ears" with 360-degree blind-angle coverage, the intelligent driving system of Denon KX has a brain that responds quickly.
Vehicle-mounted intelligent driving computing unit ADCUIt is worth mentioning that in addition to rich smart driving functions, the Dongfeng Tianlong KX King Edition smart driving tractor truck has smart driving and energy saving in sync, and is equipped with an economical and energy-saving intelligent fuel-saving control system. The system includes: global vehicle speed planning, predictive cruise control (PCC), dynamic intelligent distance adjustment, vehicle speed recommendation reminders, etc., which effectively assists the economical and efficient operation of the entire vehicle.
The first thing you need to understand is ACC single-lane automatic cruise, which is what we often call ACC adaptive cruise. The biggest difference between this kind of navigation and traditional cruise control is that it can achieve "adaptive" cruise speed. After one-button activation, it can ensure that the vehicle drives in line with the vehicle in front in the lane. At this time, the driver's right foot can be taken off the accelerator pedal, saying goodbye to the fatigue of pressing the accelerator for a long time. The second is high-speed navigation assistance (Routing), which is part of the ACC adaptive cruise function. When it is turned on, it can realize the automatic car following function of "the vehicle in front accelerates, I accelerate, the vehicle in front slows down, I slow down" in the same lane, without driving. Manual intervention by the operator. The other is the intelligent avoidance (Nudge) function. During the application of adaptive cruise, if there is a "blocking" phenomenon of other vehicles due to the distance between the vehicle in front and the vehicle in front is too large, the vehicle will automatically avoid, re-identify the following target, and adjust distance between vehicles and continue to automatically follow the vehicle.
Many smart driving functions are integrated on the left side of the multi-function steering wheelMatched with ACC adaptive cruise is the lane centering control (LCC) function. When the two are turned on simultaneously, the system can always ensure that the vehicle stays on both sides of the lane based on the recognition information of the lane markings on both sides by the body sensor or the road condition indication of the satellite navigation. Drive in the center of the road. At this time, the driver only needs to place his hands lightly on the steering wheel without deliberate manipulation (laws do not allow hands to take off the steering wheel while driving), effectively avoiding lane departure. What needs to be reminded here is: During the activation of this function, if you do not turn on the turn signal to change lanes, the instrument information will prompt you with a slight sense of direction intervention, but the system will not forcibly prevent the lane change.
580 HP Cummins Z13 Diesel EngineThe vehicle distance/vehicle speed adjustment function is mainly aimed at setting the following distance and cruising speed. During the automatic following process, the driver can manually adjust the cruise speed (+ or -) and following distance (long or short) at any time according to actual needs. The vehicle also has intelligent automatic distance and speed control. Function, convenient and fast. The function of the traffic jam assist (Stop & Go) is that in addition to the automatic car following function, even if the road conditions are congested and the car in front stops, it can also realize full-speed adaptive cruise with follow-to-stop and follow-to-start, and the entire process does not require manual intervention.

These two functions belong to the “+” part of L2+ assisted driving. The application of this function is very simple, just turn on the turn signal lever, and the system probes and sensors can automatically change lanes based on the road conditions on both sides while ensuring safety. However, if during the automatic lane change process, there is a vehicle approaching quickly (higher than the own vehicle speed) behind the pre-change lane, the system will automatically avoid it, delay the lane change, and then implement the automatic lane change after confirming safety, which is very smart.
Taking safety as the premise, fully liberating the driver's hands and feet and alleviating driving fatigue; maximizing driving safety and improving operational efficiency. This is Dongfeng Intelligent Driving's new empowerment of modern high-end trucks. In addition to the Tianlong KX smart driving version, Dongfeng commercial vehicles also have the Tianlong GX version of the smart driving system. Through these new technologies of Dongfeng Intelligent Driving, we can deeply perceive Dongfeng Commercial Vehicles’ ingenious car-making spirit in the corporate philosophy of “Everything comes from reliability”. As Tu Yilin, the person in charge of Dongfeng Intelligent Driving Vehicles, said in an interview: "The high-end of heavy trucks is not about luxury equipment or the accumulation of luxury configurations, but about making heavy truck driving smarter, more comfortable, and safer. The advancement of Dongfeng Commercial Vehicle Intelligent Heavy Truck truly realizes the "end-to-end" truck NOA between high-speed toll stations through ultra-long-distance sensing algorithms, adaptive robust control algorithms, and intelligent driving decision-making and fuel-saving algorithms. "Navigation-assisted driving" technology. We accelerate iterative updates of algorithms based on massive amounts of real operational data, bringing stable and sustainable safety and cost reduction benefits to customers."
