Avnet: Smart Cockpits Will Redefine Human-Computer Interaction

Since then, a revolution around the intelligentization of the car cockpit has begun, and various car manufacturers have begun to think about how to make their central control screen bigger and bigger; when you walk into a 4S store, the sales staff will not only introduce In addition to the normal characteristics of the model’s horsepower, torque, fuel consumption (or battery life), etc., you will always be invited to sit in the cockpit and look at the big screen…

In 2012, when people got into the Tesla Model S for the first time, the Metropolitan was amazed by the 17-inch central control screen in the center of the cockpit – the messy instruments and information displays in the cockpit were all integrated. On a touchscreen that is the size of two iPads!

Since then, a revolution around the intelligentization of the car cockpit has begun, and various car manufacturers have begun to think about how to make their central control screen bigger and bigger; when you walk into a 4S store, the sales staff will not only introduce In addition to the normal characteristics of the model’s horsepower, torque, fuel consumption (or battery life), etc., you will always be invited to sit in the cockpit and look at the big screen…

From car to smart cockpit

As a means of transportation, everyone gradually discovered that people’s interest in cars today is more and more outside the main business of “transportation tools”, which also makes the car alienated into an unfamiliar thing from a traditional perspective.

In fact, the car’s “doing no business” has a long history. If we trace the origin, it may start from the day when the radio was put into the cockpit. Since then, the functions carried by the car cockpit have become more and more abundant. For example, in order to pursue a higher sound quality experience, a CD player was added; the addition of a Display screen made the intuitive and beautiful graphical interface “on the car”, and then matured applications such as GPS navigation; in-vehicle network And the development of wireless communication also enables communication and data interaction between car cockpit equipment and other external and internal Electronic devices… As a result, a system with relatively complete in-vehicle infotainment functions has gradually taken shape, which is usually located in the center of the cockpit. , known as the “car machine”.

But so far, no matter how cool the car machine is – such as adding 3D games, etc. – it is still a car machine, and it can’t be called a smart cockpit. There are several reasons:

• First, fundamentally speaking, the car machine has not entered the core driving information field, but is still circling around peripheral functions such as infotainment;

• Second, in terms of Human-Machine Interaction (HMI), traditional car machines lack new ideas, and are subject to the particularity of car products, and knobs and buttons are still the mainstream;

• Third, the data carrying capacity is insufficient. In the face of vehicles and the intelligent transportation system in which they are located, traditional vehicles will face challenges both in data transmission and data processing, and it is difficult to form a complete closed loop of automation.

Comparing with the defects of traditional car machines, our definition of the ideal smart cockpit is clear: it should be able to cover both areas of in-vehicle infotainment and driving information, provide users with intuitive and efficient human-computer interaction, and A driving and riding system that supports the transmission and processing of massive data to achieve a complete automatic control experience.

According to this standard, in fact, the central control large screen is just an innovation in the entire smart cockpit, but even so, users have already felt quite useful – many users who have experienced such a central control large screen will sigh This thing is “toxic” and will make people “addictive”. Once used, it will never go back to the “past”.

HMI: the market pivot of the smart cockpit

It is precisely because the smart cockpit has a “brainwashing” effect on users that various car companies and Tier-1 manufacturers flock to it.

According to research data from Visteon, the global market size of major smart cockpit products in 2018 was approximately US$32.9 billion, and it is expected to reach US$46.1 billion in 2022, with a compound annual growth rate of approximately 8.8%. The Chinese market seems to be more eager for smart cockpits. Research from Soochow Securities shows that the market size of China’s main smart cockpit products will reach 56.68 billion yuan in 2020, and will climb to 103 billion yuan in 2025, with a compound annual growth rate of 15.2%.

If we go deep into these macro data, we will find some more meaningful information: in these research reports, the research objects – that is, the main products of the smart cockpit – mainly include the central control display, instrument panel, HUD, driving information Display systems, infotainment systems, etc., it can be said that in addition to the “car machine”, the focus of everyone in the smart cockpit is mostly concentrated on HMI. This is not difficult to understand. In comparison, the optimization of the HMI in the cockpit is the measure that can bring users a sense of gain in the short term.

In terms of upgrading cockpit HMI, “big screen” is not the only choice, “multi-screen in one car, multi-screen linkage” will be the future trend. This is because the screen is too large, and it will be a hindrance in the cockpit with limited space, and when more and more functions are concentrated on one screen, different functions share a display interface, or switch between different functions, becomes a problem. Therefore, the in-vehicle display function is “broken into parts” and linked with each other through data, which has become the only way for smart cockpits. According to the forecast of Strategy Analytics, in some high-end cars in the future, the number of display screens may exceed 10, and the central control display, digital instrument panel, passenger entertainment screen, smart rearview mirror, transparent A-pillar, etc. will become configuration options.

HUD head-up display is also an area that everyone is actively exploring in terms of intelligent cockpit HMI. The HUD uses AR technology to project key driving information on the front windshield in a graphical way, and “superimpose” it with the actual road and environment, so that the driver can intuitively grasp it without looking away Vehicle status, and control the vehicle according to information such as navigation and safety tips. Although some professionals believe that in-vehicle HUD is not mature enough, its market inflection point has already appeared – according to data, there are 325 models equipped with HUD in new Chinese models in 2019, with a penetration rate of 6.4%, and it has been introduced. In many low-end models, it is expected that the domestic HUD penetration rate is expected to increase to 40% in the next 3-5 years.

Voice recognition, the fastest growing next-generation technology in the HMI field, is also being integrated into the smart cockpit. One of the hardest reasons for adopting voice control in the car cockpit is that other HMIs, whether it is a knob button or a touch screen, require the driver to operate “hands-on”, and before full automatic driving is realized, Any act of leaving the steering wheel is a safety hazard; while voice does not require hands-on and does not occupy the user’s visual “channel”, so the direct interference to driving is minimal. Although the performance of the voice control solution that has been “on the bus” is not satisfactory, people have reason to believe that with the sharpening and iterative upgrading of this technology in other fields such as consumer electronics, it will eventually become standard in the cockpit. It’s just a matter of time.

In addition to the above-mentioned technical and market factors, “personalization” is another driving force driving the evolution of intelligent cockpit HMI. Whether it is a touch screen or a voice, these HMI modes still require the user to issue a “command” before the car will act. Can the vehicle automatically recognize the user’s identity and automatically make personalized adjustments and settings such as seats, air conditioning, and driving routes according to the user’s preferences? At this time, electronic tags with identification functions can come in handy. NFC, UWB, etc. will be the technical options for realizing personalized HMI in future smart cockpits.

Strictly speaking, a smart cockpit should be a complete automation system including “perception, thinking, and action”. The current efforts of people on in-vehicle HMI are only a fulcrum in the development of smart cockpits, but this is a good starting point. , Starting from here, the taste of the smart cockpit will become more and more “fragrant”.
