A few days ago, the NGP imposing camp of Xiaopeng organized - Foshan Station, which has a more deep physical understanding of Xiaopeng's NGP function. Xiaopeng said that its NGP automatic navigation assisted driving function is from China Road Development. Does it currently understand China's auxiliary driving system? Compared to all keyboards, YY, the NGP function test drive is undoubtedly more convincing.

Experience the preparation of NGP - NGP Introduction and Exam

Before you sit on the driver's seat to experience the NGP function, the NGP function and the driving precautions are less than the introduction of the driving precautions, and according to the organizer, the driver must first complete the automatic auxiliary driving test within the app of Xiaopeng.

You need to watch about 15 minutes before answering questions, and then you can unlock the NGP's experience after customs clearance, you can unlock NGP experience, and have a sense of ritual. After some explanation, learning and answering, friends who have used ACC adaptive cruise should have probably understand the method of use of NGP functions, and can initially feel the power of NGP functions.

In the process of learning and exam, we can understand that compared to other new energy car brands, Xiaopeng NGP features, which are all called Navigation Guided Pilot automatic navigation assistance, is far from localization, driving the driving habits of the Chinese people. And complex actual traffic conditions are integrated into which all kinds of trucks, motorcycles, tricycles, bicycles, pedestrians, and roads such as other traffic participants.

On P7 that is not equipped with laser radar, most high-speed roads and some urban expressways covered in high-precision maps are enabled, and the user-set navigation route is realized from high-speed NGP automatic navigation assistance driving from A points to B. In real time in the driving, choose the best route in real time, realize autonomous variability, switch high-speed route, automatically enter / go out. So the P5 with laser radar will be expected to implement A point to B point city road condition NGP, have you started looking forward to it? It is a bit far away, returning to the protagonist of this article P7 NGP function.

NGP test drive experience

All the ACC, LCC and NGP open mode are operated by a wave shuttle in the right side of the steering wheel, and the specific opening method is to turn down the chart down when the vehicle is moving forward, and the normal ACC adaptive cruise function is entered. In the road segment that is not overwritten in the NGP function, open the LCC function in two downwards; when entering the NGP available area, the steering wheel icon on the liquid crystal meter will become green, dial down the NPG function.

If the LCC function has been started, when the vehicle enters the NGP available area, the system automatically switches to NGP functionality.

ACC adaptive cruise features should be very familiar, combined with many sensors and cameras all over the car, driving according to the set cruise speed when there is no car; when there is a car, the car is automatically heeling according to the settlement of the car, Realize the follow-up and follow start.

The working principle of the Auxiliary function of the LCC lane is to detect the lane line on the camera on the front windshield, so that the vehicle is maintained in the center of the lane, and it is noted that this function is not implemented by high-precision map navigation.

When the vehicle enters the NGP area, we can sit in the driver's seat after the NGP function starts. As the road conditions are allowed, the vehicle will speed up to the upper limit of the road limit. As for where the vehicle is specifically traveling with how fast the speed of the speed, it is based on the high-precision map data of Xiaopeng, without the need for driver to carry out any The speed of the vehicle speed. For the accelerated characteristics of the motor, the acceleration of the accelerated torque of the motor, the driver of novice or initial use NGP function may be a bit flustered on the acceleration process after the NGP started, but after familiarity, you can pay more carefully to NGP to complete.

The ALC automatic modia assistance under NGP is more exciting. Compared to certain similar systems require the driver to manually turn the running of the lamp, the vehicle can perform an autonomous variant, and NGP can achieve a fully automatic active change. When the system determines that the front car is within the speed limit of the traveling speed, the left or right lane allows the change to change the light, the system will automatically turn the light, and implement one hand without hesitation, the operation is clean. Lili, saying that it's aversion to the actions, such as an old driver with years of driving experience is not too much.

High-speed road sections or expressways covered by NGP, we can assure the driving to NGP, which can complete the high-speed automatic switching and access / drove.

When driving or saving a ramp, the vehicle will also travel in accordance with the speed limit of the ramp, greatly enhanced safety and efficiency.

In fact, there is no area covered in the NGP function. After opening the LCC, the active variant can be achieved, which is differentiated that the automatic variant in the LCC is required to take the driver first turn the light.

According to the driving habits of Chinese drivers, ALC will overtake from the left side in NGP state, and of course, it will automatically turn to the right to turn to the right. Although the modir movement simply, NGP does not force the truck in the case of potential hazards, such as the lane, there is a quick approach, or other vehicles, the system will not implement it when the target lane is changed. Lane change.

But in the actual road, there is much more complicated situation. When I test drive, I met in the automatic change process of the vehicle. The target lane had a fast forward approach to the vehicle, at this time, NGP terminated the action of continuing to change. .

There is also a typical working condition. When a ramp is turned into the main road, the NGP initially judged that it was successfully incorporated into the target lane before the carway of the main lane. However, due to the faster speed of the truck, the big truck has been running to the front of our test drive, then the vehicle is just driving to the ramp and the main fair, the left side is the truck, right side There is nowhere to go, at the time, the staff of the driver's seat and the car, the NGP could not completely have a special condition.

In both cases, if you continue to let NGP driving take over, I have not tried it. For security, I will take the vehicle to take over the vehicle.

NGP has also joined large trucks to avoid, when NGP detects large trucks, such as conditions allow it to turn away as soon as possible, if the conditions do not allow overtakes to be slightly decelerated, avoiding long and big trucks parallel. This is a quite localized and effectively avoids the details of the potential risks, because the old driver knows that the small passenger cars should not have large vehicles such as large trucks in parallel.

In the high-speed corner, I also experience NGP-based map-based ATC adaptive curve cruise, and the vehicle began to slow down in front of the turn, and the vehicle slowly returned to the road limit after the corner was over.

When the current high speed will be saved, the vehicle will start to take the right driveway 2 kilometers in advance, and this is much more experienced than the navigation.

About 2 km prior to the road section of the NGP is going out, the vehicle will use sound and vibration to prompt the driver to take over the vehicle in advance. Like the second-line big city like Foshan, NGP has not been able to do high coverage of the ramp and express roads, and believe that Xiaopeng is also improving.

NGP also joined the night overtaking reminder function, automatically flashing three headlights before taking the front car before taking the front car, which is also very bonded in the actual driving scene. Unfortunately, this test car has not had the opportunity to experience this feature.

Before this experience camp, Xiaopeng was a total of 3675km NGP expedition challenge from Guangzhou to Beijing, and obtained several specific data after completion, and the success rate of the changedrison over-vehicle was 94.41%, and the success rate of outlet / into the high speed ramp was 92.76%. The tunnel is 94.95% through the success rate, and the average is 0.71 per 100 kilometers.

This is a great achievement in the intelligent driving assistance field, but not 100% success rate depends on Xiaopeng NGP to temporarily still a secondary driving system, the driver still pays attention to the road conditions and ready to take over the vehicle. It cannot be too dependent on the NGP function, which is clearly explained in the lectures before testing NGP and the test questions.

A little opinions and suggestions for NGP

When NGP works, we can see the virtual lane and the surrounding environment detected by the system, including the dotted lines of the lane, the roadside guardrail, the obstacle on the roadside, and the detected differences. Types of vehicles, etc. However, the virtual line of the screen displays data based on high-profile maps, and does not bind to the image analysis of the camera, it is inevitable that the road sign has changed, and the map data has not been kept in the case, so it does not rule out the NGP in this situation. The case of the line will be made when the automatic changes.

Since the user does not know which road sections have been covered by NGP, it is not clear which road sections have been increased, plus the green steering wheel icon on the liquid crystal meter when it is not necessarily not possible to pay attention to the green steering wheel icon on the LCD instrument, so I hope the system The voice reminder that can be added when the vehicle is entered or drove out of the NGP coverage, and the "NGP opening", "LCC On" or "ACC Open" such as "NGP", "LCC On" or "ACC Open" are displayed on the liquid crystal solution.

Xiaopeng NGP allows the driver's destination time only 30 seconds, that is, the system needs to detect steering wheel steering inputs in 30 seconds. If there is still no steering wheel action system after 30 seconds, the system will issue alert to finally exit NGP function and Deceleration is slow to park. Compared to some similar models, the system is less sensitive to the steering wheel, if the hand is lightly placed on the steering wheel or gently holding the steering wheel, the system does not necessarily detect steering input, often after the warning is issued, the driver needs to use a slightly large strength. Turn the steering wheel, causing a small change in the direction of the head, although this has little impact on the safety of the entire NGP auxiliary driving process, but always affects the user experience to a certain extent.

Overalll

In general, compared to most similar systems on the market, individuals believe that automatically switch on the highway, automatically switch the highway, automatically enter / drive the ramp, automatic large truck circumvention, ALC automatic variability and ATC adaptive corner cruise and other functions are Xiaopeng NGP to do well, and the speed and effectiveness of Xiaopeng intelligent driving localization.

I believe that with the continuous upgrading of map data, smart driving algorithms and sensor hardware equipment, Xiaopeng's NGP function will go further.
