In fact, the most important thing to study this proposition lies in two points: that is, before the automobile meets intelligence, its tool attributes are large enough, that is, there is not much other added value; On the other hand, given intelligent attributes should be strong enough. By observing the effect of the combination of the two, we can probably see the role played by intelligent attributes.
A good case comes from Seles Huawei's wise choice of SF5. Before Huawei's technical blessing, it was a relatively unknown but low-key and pragmatic automobile brand from Chongqing, so it settled down and took a self-sustaining technical route. Thanks to Huawei's technology, it boarded Huawei's national offline direct store and became a well-known automobile brand overnight.
What was the experience of Huawei and Celeste's first car SF5? Recently, we finally had a chance to test drive this Huawei SF5.
Similar to Ideal and Dongfeng Lantu, in terms of technical route, Tianhong Huawei Zhixuan SF5 is first of all an extended-range electric vehicle, which is jointly built by Tianhong and Huawei, integrating the superior technologies of both parties, and the product is positioned as "high-performance electric drive coupe SUV".
Judging from the power drive unit, this car is equipped with the hump intelligent extended range system developed by Celeste. Firstly, 1.5T four-cylinder engine is used as the range extender to supplement the power. Celeste technicians introduced that it has higher efficiency and less jitter than another three-cylinder engine. Both the generator and the generator control system are developed and mass-produced, achieving better matching.
Among the front and rear double motors, the front motor adopts SEP200 motor independently developed by Seles, and the rear motor is provided by Huawei, and the model is Drive ONE three-in-one electric drive system.
SEP200 asynchronous AC motor is independently developed by Cyrus, which is more explosive. Then Huawei permanent magnet synchronous motor has the advantages of low power consumption and high efficiency, and can better adapt to the congestion environment. According to Cyrus, the two can be combined in corresponding scenes to achieve the best efficiency. However, after the double motors are started, the maximum power of the whole vehicle can reach 405kW, and the acceleration of 0- 100km/h takes only 4.68 seconds.
According to the parameters in the book, the mechanical part of SF5 selected by Celeste Huawei is indeed well configured. First of all, Huawei chose SF5 equipped with aluminum chassis, which greatly optimized the lightweight design. At the same time, the flexible design of the subframe can improve the performance of shock absorption and noise reduction. The front suspension adopts the structure of upper and lower double ball heads and double wishbones, and the rear suspension adopts trapezoidal multi-links, which are the core configurations concerned by China automobile consumers.
The location of our test drive is a country road near Jinhai Lake Scenic Area in Pinggu. For safety reasons, we don't have much chance to try its extreme acceleration, but maybe it's because we prefer to set it in comfort mode. At this time, the steering wheel is gently adjusted, and the dynamic response is not so fast. It doesn't feel like a performance beast of 4.68 seconds.
Another reason I like comfort mode is that NVH performs well. It is said that in order to achieve better mute performance in the cockpit, Celeste Huawei Smart Select SF5 adopts a 4.75mm acoustic package double-layer sound insulation glass, and the floor carpet is also wrapped with a 3M soundproof pad to cooperate with the range extender, adjust the working revolutions of the range extender and optimize the design of the air conditioning fan. Huawei, on the other hand, adopts the software technology of noise linkage suppression: by adjusting the torque distribution, optimizing the structural design, avoiding vibration points and weakening the overall noise of the system.
In terms of intelligent interaction and scene experience, many Huawei technologies are also integrated. But for ordinary users, the deepest perception is actually the central control car, which integrates Huawei HiCar solution.
Regarding the experience of the car part, it is better to directly understand the last video:
Huawei's HiCar solution can be understood as an intelligent interconnection solution for the whole scene of people, cars and homes provided by Huawei. It connects mobile devices and cars, and uses the powerful properties of cars and mobile devices and the interconnection ability of multiple devices to establish a pipeline between mobile phones and cars, extending the application and services of mobile phones to cars, realizing the full scene experience with mobile phones as the core, and creating a smart travel experience for consumers. This is a bit similar to Apple CarPlay, but Huawei's functions are actually more integrated.
After Huawei's mobile phone is connected with Celeste Huawei Smart Select SF5 equipped with Huawei HiCar solution, it can use navigation, music, phone calls, voice interaction and other functions.
What is worth introducing here is the application mall built into the car machine. The car can browse the app store, but you can download the app directly only through the confirmation of the connected mobile phone.
And "non-inductive connection" means that SF5 selected by Celeste Huawei supports wired connection and wireless connection, and mobile phone and car machine can enjoy the same account. For example, mobile navigation is directly displayed on the car screen after the car door is opened, and video, music and other contents also support continuous viewing according to the nodes of the previous device.
But the core is that they are connected through Huawei app store based on Huawei account, so this function is not supported when there is no relevant software in the App Store of the vehicle-mounted machine. For example, you like to listen to QQ music, but it happens that you are not in the car application mall, so you can't connect to the car without feeling-but Huawei Music can.
The experience part of Huawei HiCar reminds us of the previous experience on Audi A6 Allroad CarPlay. Apple CarPlay actually focuses on the scene of car entertainment and navigation: at that time, we used the built-in Gaode navigation of Apple CarPlay to project the screen on the central control of the car. When we need to turn left after passing an intersection, the Apple Watch on our wrist actually vibrates in advance to remind us to turn, which gives us a great shock!
Although Huawei also has wearable products, according to the introduction of the staff that day, such exquisite functions may need further optimization.
In addition, Huawei HiCar can also realize the interconnection of IoT devices, and users can control home smart devices through "away from home mode" or "home mode" with one click in the car. For example, users can remotely turn on the air conditioner at home before getting off the bus, and when they find that they forgot to turn off the TV after leaving, the car can be turned off with one button. After the actual experience, the operation card will "jump out" directly to the central control with the access of the terminal, which is very convenient to experience.
Huawei's audio technology also "got on the bus" for the first time. Selis Huawei Smart Select SF5 has built-in 1 1 audio units, including 2 symmetrical bass units, 4 treble units, 4 medium bass units and 1 mid-full-frequency units. It is mainly tuned by Huawei's original audio technology core team and acoustic experts. By optimizing the tuning, the sound layering and vocal clarity are improved, so that users can have a better experience when listening to pop music and folk songs. In addition, by matching the motor noise suppression technology, liquid silencing technology, and pre-double-layer sound insulation glass setting, the 38dB library-level mute effect is finally achieved.
