[YesAuto electric car] Just in mid-September, we just brought you an OTA content of Xiaopeng Motors P7; after a month, P7 pushed the car to users in batches this time. The most important OTA ever-Xmart OS 2.1.0 version OTA. Xiaopeng Motors P7 has just opened ACC, LCC and other auxiliary driving functions in this OTA. At the same time, it also brings us an unprecedented experience-full-scenario voice; how exciting is this upgrade? You'll know by reading the article.
Xiaopeng Motors P7 has a lot of OTA projects this time, but the function upgrades are mainly concentrated in two aspects: one is the assisted driving part, and the other is the intelligent experience part.
Although P7 has just opened ACC, LCC and other assisted driving systems, I believe you are not unfamiliar with these functions, because there are too many models with these capabilities, so let’s take a look at the innovation of P7 in the intelligent interaction part. Trust me, this is more interesting.
Before talking about the topic, let me share with you the OTA process of Xiaopeng Motors P7. Generally, the OTA upgrade of a vehicle cannot be solved in a few minutes, and some models cannot be locked during the manual OTA process. I have experienced the scene of waiting for the OTA in the car at midnight, so I suggest you take good care of the OTA prompts before choosing manual upgrade Or make an appointment to upgrade automatically. However, the P7 does a good job at this point. First, the system will prompt the user “cannot lock or drive during manual upgrade”. Secondly, according to the official introduction, during the manual upgrade of the vehicle, the user can also choose to “interrupt the upgrade” at any time to restore. The driving and lockable state of the vehicle.
It is quite reliable to make an appointment to upgrade, but it is recommended that you put your car in the open parking lot before OTA, because the network signal of the car machine is not as good as the mobile phone. If the car is parked in the underground garage, the OTA process may be Affected by network instability.
The first new feature I experienced after the completion of the vehicle OTA was the full-scenario voice; Zhao Hengyi, the voice manager of Xiaopeng Motors, believes that smart driving is a factor that distinguishes smart cars from ordinary cars, while in the car, voice interaction is the key point. . In previous exchanges, Zhao Hengyi said that the current business reach rate of many voice assistants (function realization ability, that is, what it can do) and the naturalness of interaction are in urgent need of improvement; in this OTA on P7, I found him The problems mentioned have been optimized to a large extent.
“Say it when you see it” is a key point in the full-scenario voice. One of the functions of this feature is to enable the voice assistant to achieve more functional control. To put it simply, in the five self-developed applications of navigation, music, air conditioning, car control, and system settings, the icons and buttons that appear on the screen can be replaced by touch through the voice assistant. In the past, voice assistants had more limited functions, such as being able to open and switch music, but could not realize the selection of playlists and the order of songs, but now the small P with the ability to “see and speak” can be realized.
If you don’t understand what “you can say when you see it” and don’t know how it can bring convenience to users, you can watch the demo video below. Some basic functional operations can be achieved through the voice assistant. Maybe you have questions, is it only available under 5 self-developed applications, is that enough? According to previous research conducted by Xiaopeng Motors, the most used voice interaction functions are nothing more than air conditioning, navigation, and music. Recall that our own car scenes are indeed the case. Even if the car has such rich functions, the basic functions are commonly used. .
In addition, if you watch the video, you should be able to find that since the first time I wake up the voice assistant, I have never said the wake-up word “Hello little P” again. As we mentioned above, many voice assistants not only need to improve the service reach rate, but also need to optimize the naturalness of the interaction; full-scenario voice supports no wake-up for a period of time, so I only said the wake-up word in the video. In fact, the wake-up-free function is also a way to improve the naturalness of the interaction, avoiding the user to say “Hello little P, I want XXX” before each instruction. Of course, in order to achieve the effect of accurately and capturing instructions at any time, the voice assistant needs a lot of Order reserves in order to make correct judgments.
Speaking of natural interaction, the commands of many voice assistants are relatively fixed and rigid at present, and it may be impossible for users to make a mistake or say one less word. In the P7 full-scenario voice, users can give instructions relatively freely. Basically, you can say what you think about this instruction, so you can say it. This greatly reduces the difficulty of getting started and can also improve the user's goodwill.
Regarding voice, let's extend it a bit. Many people don't like full touch operation, they think it is not as convenient as traditional physical buttons/knobs, but from an engineer's point of view, this may be intentional. As far as we know, in fact, some designs on car machines do have guiding purposes. For example, engineers want users to experience the convenience brought by voice interaction, and some of their functions will be designed to be more suitable for voice operations.
For voice assistants, it is still quite technically difficult to be awakened and visible, such as capturing ability, semantic understanding, language processing ability, etc., all need to reach a high level. Such a voice assistant is great, but it will definitely improve. At present, the small P also has a certain customization ability. Users can train the small P on their own, and finally realize the customized experience of vehicle settings, air conditioning, music and other functions; in the future, the voice assistant may be like a friend, like your iron Like buddies, if you understand your habits and preferences, you can communicate with it barrier-free, smoothly, and naturally, and it can also complete various operations just to your liking. It is up to the engineers to complete everything. As ordinary consumers, we can hold a heart that is willing to accept and feel new things.
Regarding Little P, in addition to its hard power, it is even more adorable this time. We believe that the virtual image of the voice assistant or the physical image like NIO NOMI can increase the emotional communication ability between the voice assistant and the user, and this time the “dress up” of the small P, including a customized avatar, provides users with more choices. Sex, and the actual experience effect is quite good, it is worth a try.
This is the “anti-motion sickness mode”, this mode does not change the braking force of the vehicle, but the subjective feeling of the power output is similar to that of the economic mode, and the output is relatively flat, which brings a comfortable ride to the passengers. Xiaopeng Motors P7 has two levels of kinetic energy recovery, “low” and “high”, and the kinetic energy recovery in the Shuxiang driving mode is even smaller than the conventional “low”, which has reached or even surpassed the gliding ability of fuel vehicles. From this aspect, passengers can also get a smoother ride experience.
The last thing to talk about is a feature that is more friendly to northern riders-low-temperature battery preheating. At present, most pure electric vehicles already have a battery heating system, but this consumes the power of the power battery. The disadvantage is that the vehicle's endurance is reduced; the power source for the P7 low-temperature battery preheating is the charging pile, so you only It is enough to pay a little more charging fee, which can reduce the impact of low temperature on vehicle endurance to a certain extent.
About the experience of some intelligent functions, this is probably the case. Before talking about the OTA of the P7 assisted driving, let's summarize the above content first. What is worthy of recognition is that the Xiaopeng Automotive Voice self-research team has created a “full scene voice” capability that is innovative, functional, and practical. As Zhao Hengyi said, voice interaction is an upgrade and supplement of the experience, not a substitute for any kind of interaction; indeed, it is better to choose more than no choice. This also brings us more thinking, and the future of voice assistants What capabilities are needed to make users more receptive and use the voice interaction mode more frequently? Or will another new and better human-computer interaction model be born in the future?
Including pure electric vehicles and fuel vehicles, there are already too many models with L2 assisted driving capabilities, and even products such as Haval H6 and Guangqi Honda Fit, which cost about 100,000 yuan, have some assisted driving functions. For Xiaopeng Motors P7, it sells for more than 200,000 yuan, and the official also defines it as a “smart car”, and Xiaopeng Motors G3 already has some assisted driving functions, so the P7 will open up the practice of assisted driving half a year after its launch. It's definitely not a surprise, it's just worthy of recognition.
It can be seen from the list of assisted driving functions in the car that the P7 currently only opens some assisted driving functions, but the functions like adaptive cruise and lane keeping are basically more commonly used, so it can meet the needs of users, but I am still very I hope P7 can open active brakes as soon as possible. In terms of the actual experience of assisted driving, the performance of the P7 is not significantly better than other competing models of the same level, but it can indeed reach the mainstream level, and it has also made some progress compared with the Xiaopeng Motors G3.
Xiaopeng Motors P7's adaptive cruise following distance can be adjusted in 6 gears. There are really not many models that can give users so many choices. However, even at the 1st gear following distance, the distance between the P7 and the vehicle in front is relatively long, so Probably few users will use the farther following distance gear. Another good point is that the vehicle rarely accelerates or decelerates in adaptive cruise, and the experience is good.
In addition, regarding lane keeping, the P7 can keep driving in the middle of the lane relatively steadily, and the steering wheel is not too much to fine-tune the direction, and the experience is better. When the vehicle is driving on a road with poor lighting conditions, the lane keeping system can still better recognize the lane line. When the vehicle is “powerless”, various sounds/vibration reminders + pre-tensioned seat belt tensioning can also be timely and effective Promptly remind the driver to take over the vehicle.
We have done an assisted driving test of Xiaopeng Motors G3 before. In the lane change assist part, the G3's lane change logic is more cautious, and the lane change rhythm is slightly slower. On the P7, the safety redundancy of the lane change assist system is also large. The vehicle is allowed to change lanes only when the vehicle is far away from the front and rear of the target lane; however, the P7 has better lane change efficiency and smoothness than G3 Ascension, we can think that it is closer to the lane changing operation of a real driver.
Although the current assisted driving functions of Xiaopeng Motors P7 are not rich, don't worry, the hardware level of the car is sufficient to support it to achieve higher-level assisted driving. In the assisted driving hardware part, the P7 has 14 cameras, 12 ultrasonic radars, 5 millimeter wave radars, dual-frequency high-precision GPS, and it supports high-precision maps and V2X technology; at the same time on the computing unit, the car is equipped with NVIDIA DRIVE Xavier's deep learning computing power (DL TOPS) has reached 30 Tops. As a reference, Tesla Autopilot 2.5 and Autopilot 3.0 have computing powers of 24 Tops and 144 Tops, respectively.
Just before Xiaopeng Motors’ 1024 Smart Days, we were also invited to experience the engineering version of Xiaopeng’s P7 (High Speed Autonomous Navigation Driving). Those who are interested can review the video we released: “The evolution of Xiaopeng’s NGP has just begun. Assisted driving experience.” In the experience, the car can realize functions such as autonomous up and down high-speed ramps, autonomous lane changes, and in the execution of many actions, it is closer to the operating habits and style of real drivers, which is enough to prove that the Xiaopeng Motors P7 is in automatic/assisted Driving potential.
In addition, whether it is about assisted driving or smart cockpit or the overall vehicle, Xiaopeng Motors has always said that it is to be the “smart car that understands China best.” Indeed, first in the smart cockpit part, Xiaopeng Motors P7 and G3 have fully integrated localized applications, and secondly in the assisted driving part, its NGP system also shows a better response to some complex high-speed and ramp conditions. Even He Xiaopeng, the founder of Xiaopeng Motors, said that, for example, in the case of heavy traffic, how to assist driving to avoid congestion is what they are considering and doing. In the future, when the mass-production version of NGP or autonomous driving really comes, can Xiaopeng Motors make products suitable for China's road conditions that truly have a “driver's sense of control”? I feel very hopeful. What's more worth looking forward to is that Xiaopeng Motors is expected to officially push NGP to P7 users in the first quarter of 2021, hoping that it will bring us surprises.
In the Xiaopeng Auto 1024 Smart Day, He Xiaopeng also mentioned an idea that he very much wanted to advocate: The track of smart cars should not only compete in quantity, but also value high quality. Indeed, not only in the field of smart cars, many products are constantly stacking configurations and technologies, but is the actual experience of these things really good? Is it convenient for consumers to use it? Not necessarily. Just like the voice assistant, there are too many models currently equipped with voice control system, but most of them are reduced to “cumbersome”, it is better not to use it; like the assisted driving, the user originally wanted to rely on it to relieve fatigue, but use it In the future, it will be more “fearful”.
Xiaopeng Motors hopes to be fully controllable in terms of hardware, software, scenes, data, etc., and to be forward-looking and do different things in terms of products and technology. This road is undoubtedly difficult, but fortunately, Xiaopeng Motors' goals are clear enough and hard enough. At the same time, the P7's OTA and NGP show is also gratifying. When can we come in the future? I believe these outstanding car companies in China can give answers.
