Someone said to me before: Isn't the cockpit of a smart car "stuffed" with a tablet?
But is this really the case? Let's start with a video.
So why is aito asking the M5 to "look" like a tablet? There are actually two parts here: software and hardware:
01
Most of the physical keys are eliminated
In the cockpit of the AITO Inquisition M5, there are almost no other physical buttons except for square control, window control, and double flash. There is only one instrument screen and a central control screen, and the shape and size of the central control screen are also very similar to a tablet.
Although more and more brand models, including Tesla, have begun to carry out such designs, this does not mean that this design direction must be completely correct.
02
Low learning costs
Take aiTO M5's Hongmeng vehicle OS, its HMI interaction design and UI design are very similar to the Hongmeng OS of mobile devices, so the visualization and interaction logic of the software are also like a tablet.
Nowadays, we who are accustomed to using smart phones and tablets already have a basic understanding of such system interfaces and interactive logic, so the threshold for getting started has become very low.
"Adaptation" to the driving scenario is essential
The homepage of this Hongmeng car OS is a number of switchable wallpapers, except for the Dock bar and the Smart Dock bar, most of the space can not be interacted with.
Nowadays, many car and machine systems will adopt the design of "navigation is home page", and present common functions with different cards such as content playback and air conditioning. However, the arrangement of aito M5 function cards and icons depends on the order of arrangement, and users have to make trade-offs.
It is undeniable that the aesthetics of the interior interaction design are expanded on the basis of driving safety and efficient interaction.
For models that use large-screen cars and cancel physical buttons, such an interactive design has no problems for the operation of static scenes, but the impact on operations in dynamic driving scenarios will be relatively large. When the gaze is focused on frequent screen interactions, it can affect driving safety due to distraction.
In addition, when driving on bumpy roads, the accuracy and efficiency of operation will be greatly reduced.
Therefore, this set of Hongmeng vehicle OS of AITO Q&I M5 must make enough "adaptation" for driving scenarios in HMI interaction design.
At present, the main interaction and information in this set of Hongmeng vehicle OS are arranged within the range suitable for driver interaction and observation, which is also the difference between Hongmeng vehicle OS and mobile device OS.
Such a design can be equipped with a large control screen, cancel a large number of physical buttons, as far as possible to reduce the driver's interaction time to the screen, scanning time, so that the driver can complete the interaction faster, after the information acquisition can quickly return the attention to the driving.
In addition, AITO M5 also sets up applications with "P", mainly video applications, which can only be used in the parking state to avoid the driver's distraction in the driving scene.
"Soft Power" Combined with "Hard Power"
In the past few days of experiencing aito Q&A M5, the fast response speed and high fluency of this set of car machines are the points that impressed me the most. It can be said that it has a strong strength in the current car machine system with touch screen as the core interactive form.
This experience covers almost all aspects related to interaction, such as the opening and running of applications, touch interactions, voice interactions, and so on.
So, what's behind this "fast"?
In people's usual cognition, the "fast" of the human-computer interface will be basically divided into three reasons:
High redundancy of hardware configuration;
The operating mechanism is simple;
"Optimization" is good.
In fact, "optimized" is a very metaphysical statement that can be used to explain many claims that do not give immediate answers.
But in terms of hardware, the cockpit SoC of the AITO Inquisition M5 uses Huawei's Kirin 990A chip, and the computing power is about 3.5TOPS. As a benchmark product with Qualcomm 8155, the vehicle grade Kirin 990A chip is mainly used in the car cockpit, and is more suitable for the operation of Hongmeng Ecology on the car side.
In terms of software, I speculate that Huawei's "Ark Compiler" or "Microkernel" technology and architecture are applied in Hongmeng's in-vehicle OS.
Speaking of compilation techniques, this is a technology that is able to translate code into machine language. The compiler is the bridge between the software and the chip, and its performance will directly affect the operational efficiency of the entire system.
We are familiar with some mobile devices "long-term card", which is actually related to the compilation technology. In the past, the most common practice was to configure the pile and make a lot of hardware redundancy, but this was not a cure for the symptoms.
The Ark compiler adopts a new system and application compilation and operation mechanism, statically compiles all Java semantics, and directly translates the Java language into a machine language (static compilation), eliminating the additional overhead of dynamic compilation of virtual machines and achieving the compatibility of development and running efficiency.
If we think of the compiler as a translator, it is like going to a country where the language is not the same, and we can only communicate through simultaneous translation (virtual machine), which is inevitably inefficient. Huawei's Ark compiler is more like directly allowing people to gain language capabilities, so that they can get rid of simultaneous translation (virtual machines) and communicate with locals more freely.
Therefore, we believe that the "combination of soft and hard" from Huawei is the reason behind the "fast response" and "smooth interaction" of the AITO Q&A M5 Shanghongmeng car OS.
At last
Returning to the question that the cockpit of a smart car is a tablet is not appropriate, because the driving scenario is very different from the use scenario of mobile devices.
Even if some car machines look like a tablet computer, if it does not adapt enough to the driving scene, it will bring great hidden dangers to the interactive safety of the driving scene.
