With the development trend of the "new four modernizations" of automobiles, the automobile industry is experiencing the biggest change in the past 100 years, among which "intelligent networking" has become the main factor for consumers to buy cars. As for the "intelligent network", the customer has paid much attention to it with Huawei’s HarmonyOS Harmony OS system since it was listed. Thanks to Huawei’s deep empowerment and the construction of Huawei’s ecosystem, the customer M5 realized the opening of the car and the mobile phone account, further improving the closed-loop ecological construction. At the same time, it has the same interactive experience, response speed and software ecology as the mobile phone, which is unmatched by other vehicles in the automobile market at present, and it can be said that it is unique. So, what are the highlights of this intelligent car machine system in HarmonyOS? Can it satisfy young consumers’ pursuit of "technology"? This issue of "Intelligent Car Machine Evaluation" will comprehensively evaluate the car machine system of the M5 in terms of system hardware and system software.

First, the system hardware

1. Hardware parameters

The M5 adopts the conventional "double screen" design, in which the dashboard is embedded and the central control panel is suspended. The two screens not only have very clear resolution, but also have considerable area and large visual area. The overall display effect is worthy of praise. It is worth mentioning that in the setting of the central control panel vehicle, the brightness of the LCD instrument and the central control panel can also be adjusted. This design is like adjusting the brightness of the mobile pho ne screen, which is a boon for those consumers who are "photophobic".

2. Hardware evaluation

The M5 central control panel is designed with full touch control, and the functions of the main interface and air conditioning control are integrated at the bottom of the screen, which makes it more convenient for consumers to operate. Two air outlets are designed at the bottom of the screen, and the "double flashing" danger warning light is placed in the center of the air outlet, which is also convenient to operate.

Multi-function steering wheel buttons have reasonable layout, large button area, and a certain distance between buttons, which is not easy to touch. The two buttons on the upper left side of the steering wheel are respectively the activation button of the voice interacti on system and the "custom" function, in which the "custom" function can be set in the central control panel, and it can provide the functions of switching the full-screen map of the instrument, switching the multimedia sound source, taking photos inside, taking photos (driving recorder) and capturing videos (driving recorder). On the right side of the steering wheel, there are telephone connection, music switching and volume adjustment. Even for the first time, users do not need to learn the cost, and it is very convenient to use.

Second, the software system

1. Software parameters

The HarmonyOS system of HarmonyOS, which is carried by Wenjie M5, is developed based on the bottom layer of Linux and supports OTA upgrade. When the driver opens the door, the car system will be turned on immediately, and the whole process will be about 1s, and the response speed is quite fast. In addition, in the car system, users can find a "owner’s guide", which is equipped with an electronic manual and an introduction of the M5 highlight function, and basically every setting will be explained very clearly, and some functions will also provide video demonstrations.

2. Basic application evaluation

This HarmonyOS Harmony OS system of M5 can be regarded as a Huawei tablet computer, but it incorporates many vehicle functions. The icons of various functions of the interface are consistent with those of Huawei mobile phone, which looks very friendly, and the operation logic is also consistent with the mobile phone. For example, the drop-down menu is a common function of the system and is very convenient to use.

It is worth mentioning that the operating fluency of this HarmonyOS Harmony OS system is the fastest among more than 100 cars I have tested. Basically, when you click a certain function, the function interface will be displayed immediately, and there is no jamming phenomenon when you enter/exit the app. On the other hand, there are many complaints about "car machine jamming" in many new energy vehicles nowadays, which greatly affects the car experience of car owners.

In addition, the M5 does not provide fancy theme mode, but only provides two theme modes: black and white. Consumers can also choose the "adaptive theme" mode, with white as the main theme during the day and black as the main theme at night. It is worth noting that the theme mode is linked by the dashboard and the central control panel.

3. Comfort application evaluation

The air conditioning panel of Wujie M5 is integrated at the bottom of the car screen, which is very convenient to operate. After entering the air conditioning interface, the top can adjust the air volume, and the wind direction adjustment can not only click the fixed mode provided below, but also the driver can drag the air outlet of the air conditioner he wants to adjust and adjust it to a reasonable position. At the same time, the air conditioning system also provides a "sweeping" mode, which is very intelligent, just like the electric fan that can shake its head at home.

The "fragrance" function is also provided in the upper right corner of the air-conditioning interface. After clicking to enter, not only three fragrance types are provided for consumers to choose, but also the concentration can be selected, which is very subtle.

The left and right sides of the air-conditioned area are also designed with functions such as seat heating, seat ventilation and seat massage. The driver can choose any seat on the icon to adjust, and the convenience is good.

It is worth mentioning that the M5 also provides a variety of cockpit scene modes, mainly including three scenes of rest, meditation and breathing. Under different environmental sounds, users can relax physically and mentally. It is a pity that this function cannot be enabled when the vehicle’s power is less than 30%, which may be due to the fact that noise will be brought into the vehicle when the engine is started, which will affect the user experience.

4. Map navigation evaluation

The navigation system of Wenjie M5 is based on the core of Gaode map, and its functions are placed at the bottom of the main interface. After entering the navigation interface, thanks to the large central control screen, the display effect is very clear.

When inputting the destination, the navigation system provides voice search in addition to the common pinyin and handwriting search methods, among which Mandarin, dialect and English are also supported by voice, and the voice recognition rate is also very accurate. Of course, consumers can also search for destinations directly through intelligent voice interaction.

When searching for a destination, the navigation system provides the function of destination association, which further enhances the search convenience. After the destination is selected, navigation also provides intelligent recommendation, avoiding congestion, not taking the high speed, giving priority to the high speed, charging less, giving priority to the main road and the fastest route, and can also search along the way.

After confirming the route, the navigation interface can be mapped not only to the center of the dashboard, but also to the HUD head-up display. When the vehicle is driving, the boundary M5 also provides road traffic identification and maps the road signs to the in-vehicle navigation system. In addition, this navigation system also has a fast response speed for road refreshing and timeliness.

In addition, the intelligent voice of M5 provides four types: female voice, children’s voice, girl voice and male voice, and this voice will also follow the navigation voice prompts.

5, audio-visual entertainment evaluation

This HarmonyOS system in HarmonyOS, developed by M5, is equipped with Huawei application market at the software level, which can provide a variety of third-party apps internally, and the adaptation of each app has been done quite well, and there is basically no slot in its use.

In terms of radios that consumers often use, the M5 provides not only common FM/AM channels, but also Internet radio stations, which are not only rich in choices, but also planned in types, so that consumers can use them more conveniently.

With the development of intelligence, cars have gradually upgraded from the attribute of transportation to the "third space" of people’s mobile intelligence, among which car audio has gradually become an important reference for users to buy cars. Wenjie M5 is equipped with HUAWEI SOUND sound system, which provides three sound stage modes and four sound effects styles. On the hardware level, AITO Wujie M5 has 19 sound generating units (4 speakers of the main driver’s headrest are optional), including 1 dual voice coil subwoofer, 4 bass units, 2 surround units, 3 center units, 5 tweeters and 4 headrest units. Three-frequency speaker composed of high, medium and low sound generating units makes the listening sense fuller and clearer.

It is worth mentioning that AITO Media M5 also provides private headrest audio, and directional audio can bring better immersive experience to drivers, effectively avoiding the unnecessary influence of music and navigation information on passengers in the car.

6. In-vehicle interconnection evaluation

As we all know, the biggest highlight of the M5 is that it is equipped with the HarmonyOS system of HarmonyOS. Therefore, for the "mobile phone interconnection", both Apple’s CarPlay and Baidu’s CarLife are its competitors, so only Huawei HiCar can be owned in this car. If you have a Huawei mobile phone, the account on your mobile phone can be connected with the car. On the mobile phone, you can check the vehicle information, adjust the air conditioner, open and close the trunk, find the location of the vehicle and so on. Of course, the "Internet of Everything" is not just that simple. For example, if you hear a favorite song on your mobile phone and click Favorite, it will be synchronized in the "I like" column of the car music function. There are many such "synchronizations", such as navigation information, take-out and favorite restaurants, etc. This is the "Internet of Everything".

7. Intelligent interactive evaluation

Intelligent voice interaction system is an important field for major manufacturers to compete with each other. In this respect, the M5 can be said to hold many opponents. It not only supports the wake-up of the steering wheel button, but also can open the voice dialogue system, and the wake-up words can be set by the owner at will. At the same time, voice can realize most of the functions of the vehicle, including air conditioning, sunroof, navigation, ambient light, driving recorder and seat heating, etc. It is worth mentioning that it can also realize continuous conversation for up to 60 seconds, and can execute two instructions at the same time, greatly improving daily convenience.

However, in the actual operation process, it is found that the driver must talk with the most standard driving posture, otherwise there will be a situation where voice recognition is not available, which needs to be improved in the later stage.

8. Driver assistance evaluation

The M5 is equipped with a 360-degree panoramic image. The cameras at all angles have high resolution, and the screen display is very clear. At the same time, it is equipped with a parking auxiliary line that can follow the steering, which is convenient for drivers to judge the parking trajectory. It is a pity that when the vehicle is close to the obstacle, the image will be distorted, which will easily affect the driver’s judgment.

In addition, the M5 is equipped with a full-speed adaptive cruise system, which can be turned on by the driver through the steering wheel button. After the function is turned on, cruise information and road traffic signs will be displayed in the full LCD instrument and HUD head-up display.


Huawei also claimed to install HarmonyOS system on Celeste, Polar Fox and other products. However, this HarmonyOS system of M5 from the UI interface, functional richness, operating habits and techniques, etc., makes people feel that this is the most HarmonyOS-like. Different from many models, the biggest highlight of this system is the construction of the ecosystem, which connects the car and mobile phone accounts, so as to achieve data synchronization. Of course, if you are a non-HarmonyOS user, you can also experience the excellent interactive experience, system response speed and software ecology of this system.

And if you are a loyal fan of Huawei, then you can achieve the "Internet of Everything", not only the interconnection between mobile phones and cars, but also the multi-directional interconnection between household appliances, cars and watches. Generally speaking, the HarmonyOS system of HarmonyOS developed by M5 has many bright spots, which can be used by consumers in daily life, and it can be said to surprise consumers in terms of reaction speed and other experience. In contrast, there are some distortions in the 360-degree panoramic image camera of the M5, and there are also some situations such as voice recognition failure in the voice interaction system. Of course, this is only Huawei’s first test of water. I believe that with the continuous upgrade through OTA in the later period, the car experience of future users will be more perfect.
