The protagonist to experience today is this brand-new signature version of Weilai ES8, which is equipped with NIO worth 39,000 yuan. Pilot is fully equipped and has a very rich automatic assisted driving function. We may wish to test NIO of the new Weilai ES8. Pilo automatic assisted driving system, see how it performs.
●? NIO？ Pilot profile
Before the actual measurement, let's introduce, NIO? Pilot consists of 1 3-way cameras, 4 panoramic cameras, 5 millimeter-wave radars, 12 ultrasonic sensors, 1 driving state detection cameras and 1 Mobileye? Q4？ Automatic driver assistance chip.
From the hardware level, NIO? The pilot is absolutely first-class At the same time, the control algorithm, underlying software and ADAS controller of autonomous driving are being developed by Weilai China and North America teams, so as to continuously update iterations through OTA upgrade in the future.
The new ES8 signature version of this test drive model, due to the optional NIO? Pilot is all-inclusive, so there is NIO? All functions of the pilot system. Specifically, NIO now? Pilot's complete set mainly provides high-speed/congestion automatic assisted driving, turn signal control lane change, road sign recognition, lane keeping function, visual fusion automatic parking system and other functions.
NIO？ The use steps of the Pilot system are very simple, because NP control buttons are integrated in the left area of the multi-function steering wheel, the middle button is NP start/close button, the up and down buttons on the left control the increase and decrease of the cruising speed of the vehicle, and the up and down buttons on the right adjust the distance from the vehicle in front.
When NP is successfully turned on, "Pilot? The voice "started" means that the driver's assisted driving has been turned on. At this point, there will be some changes in the dashboard One is that the ES8 model in the center will have a blue aperture surround effect, and the other is NIO in the lower left corner. The small icon that the pilot vehicle looked around and perceived also turned blue. In addition, NP can identify ordinary vehicles, pedestrians, bicycles/motorcycles, trucks and other vehicles, and display them on the dashboard with light gray icons.
●? Automatic assisted driving at high speed and congestion.
Is NIO the first measured experience? Pilot's high-speed and congested automatic assisted driving function is also the most commonly used function in daily driving scenes. This function is actually based on ACC adaptive cruise system, with lane departure warning and lane keeping function of auxiliary steering, thus reducing driving fatigue on urban expressways and expressways.
For example, on the urban expressway, open NIO? After the pilot, the ACC system will automatically adjust the driving speed according to the cruising speed and distance set by the driver, and the acceleration and deceleration of the vehicle are linear and gentle, giving people a feeling of peace of mind. When some front cars suddenly change lanes and enter the front of my car, NP system not only gives early warning, but also has timely braking response. However, its braking force is not as rough as other models, and it is incremental continuous application of braking force, which is quite "calm".
As for the expressway, the performance of NP is not much different. The driver can free his right foot only by adjusting the speed within the speed limit of the road section, but he should always pay attention to the road ahead and master the steering wheel to prevent accidents.
At the same time, the lane keeping function with lane departure warning and auxiliary steering can make the vehicle run smoothly in clear lane markings and keep the vehicle in the middle position. The system will also provide some assistance to the steering wheel to help drivers turn more easily. Even so, it is not recommended that the user release the steering wheel control casually, because when the system senses that the user's hand leaves the steering wheel for more than 30 seconds, the system will issue a first-level warning, and a second-level prompt will be issued after 5 seconds. At this time, the system warning sound is also more urgent. If you don't hold the steering wheel, the system will send out "take over the vehicle immediately, pilot?" Exited "voice prompts, and finally the NP system completely exits.
●? Lane keeping function (LKA)
Speaking of NIO earlier? Pilot's lane keeping function has both lane departure warning and steering assist functions, but users can adjust it on the ADAS setting interface of the central control panel. If "reminder+steering control" is selected, LKA will intervene in the first time and correct the steering wheel in time when the vehicle has a lane departure trend without turning on the turn signal, and make a sound to remind the driver.
Can you say that? LKA can effectively prevent accidental lane departure caused by driver's distraction and fatigue, and also cultivate the good habit of turning on the turn signal before changing lanes. But in some complicated scenes, the lane keeping function is somewhat conservative. For example, when the lane line is unclear or when encountering a large-angle curve, the system is more inclined to let the driver take the initiative to take over.
●? Turn signal control lane change (ALC)
In Nio? When the driver is at work, after the turn signal is toggled, the vehicle can automatically change lanes when the road conditions permit, which is the function of controlling the lane change by the turn signal. From the actual experience, the process of changing lanes is relatively stable, and there will be no sudden acceleration and deceleration. Of course, if you want to control the lane change through the turn signal, you must also meet some strict conditions, such as the speed of the car should exceed 50km/h, there are no cars in front of and behind the lane to be changed, or the distance between the cars in front and behind is far enough, then the system can complete the lane change by itself.
Open Nio? Pilot, after turning the steering wheel, if it does not meet the safety lane change situation, the dashboard will display the red route, and if the automatic lane change can be completed, the dashboard will display the green moving route.
●? Visual fusion automatic parking system
For many new drivers, the hardest thing is to stop. And this brand-new Weilai ES8, which is positioned in medium and large SUVs, will not be easy to park daily if it does not rely on the automatic parking system.
Thanks to the blessing of visual fusion automatic parking system, parking has also become very easy. First, open the parking image in the central control panel and open the search parking space. At this time, when the vehicle speed is less than 15km/h, the available parking spaces on both sides will be automatically searched. Then the system will prompt "parking space found" and display the parking space selection. At this time, you can shift gears into R gear, click the "Start Parking" button above the central control panel, and then release the brake and steering wheel to let the system complete the automatic parking operation.
From the measured experience, the whole automatic parking process is very intelligent and fast. After entering the automatic parking state, the speed of reversing the ES8 is neither slow nor slow, and it is as skilled as an old driver, which is very reassuring. At the same time, it is no longer necessary to manually switch between the D gear and the R gear after the R gear is engaged. It is worth mentioning that this visual fusion automatic parking system can clearly identify the parking space markings, so even if there are no vehicles parked on both sides, it can accurately pour into the spare parking space.
●? Edit abstract
Judging from the measured process and experience, NIO from Weilai? The Pilot automatic assisted driving system still has a good performance. The most impressive thing is that the system can gently control the acceleration, deceleration and braking, which makes people feel very comfortable, which is also in line with the positioning of its luxury brand. Of course, neo? Pilot's automatic assisted driving performance in complex scenes also has a lot of room for improvement, which is inseparable from a large number of subsequent test data and optimization work, but fortunately, Weilai Automobile will continue to complete a series of upgrades in the future OTA, and we will wait and see.
