Volvo, Qualcomm, Google are teaming up to make automotive infotainment much more smartphone-like than ever. If Wintel (Home windows plus Intel) is the default software program+{hardware} combo of the PC period, then the smartphone equal has bought to be Android and Qualcomm (Andcom? Qualdroid?). Volvo is bringing this combo to the upcoming Polestar 3 electrical SUV, which is due someday in 2022. We additionally bought a sneak peek at what the brand new interface would appear to be.
Volvo’s Polestar 2 was the primary to ship Google’s Android Automotive OS in a automotive. Not like Android Auto or Apple’s CarPlay, which run in your smartphone, Android Automotive OS has a customized model of Android preinstalled on the automotive, as the principle automotive infotainment OS. Even when you have an iPhone, your automotive nonetheless runs Android. The Polestar 2 used an x86 chip (an Intel Atom A3900), however now Volvo is pairing a Qualcomm smartphone chip with its Google smartphone OS. The Polestar 3 will ship with Qualcomm’s “Snapdragon Cockpit Platform Gen 3,” and whereas that sounds distinctive, it’s actually only a repackaged smartphone chip with just a few further options.
The mixing of automobiles with laptop expertise is at all times powerful. Automobile improvement takes round 5 years, which may appear virtually incompatible with the event tempo of smartphones and computer systems. That is nonetheless true of the 2022 Polestar 3. Qualcomm’s Gen 3 automotive platform was truly introduced again in 2019, however design wins for the platform are simply now being introduced at CES 2022. Qualcomm says the Gen 3 automotive platform is predicated on the Snapdragon 820 SoC, an ARM flagship smartphone chip from 2016. You might bear in mind this chip from telephones such because the Samsung Galaxy S7 and the Google Pixel 1. The Polestar 2’s Intel Atom was additionally from 2016.
The Gen 3 won’t be the most recent chip on the planet, however nonetheless, Volvo is on the identical {hardware} and software program platform as smartphones. Volvo ought to now have a useless easy, constant ARM improve path, because of the smartphone improvement that occurs yearly. This is hoping this consistency results in a quicker path to marketplace for the {hardware}. Qualcomm already introduced the Gen 4 automotive platform ultimately yr’s CES—it simply will not pop up in a automotive for some time.
However concerning the Gen 3’s further options: it has upgraded RF capabilities like Wi-Fi 6, 5G, and newer Bluetooth, which you could not get on the Snapdragon 820. Supporting a automotive, particularly an Android automotive, additionally means needing help for virtualization. Android can run the infotainment system, however one thing else must run the gauge cluster show behind the steering wheel. Security rules mandate that the gauge cluster cannot run Android. Android is not a real-time OS, that means it might lag if the processor is just too gradual, and that is not allowed for crucial driving parts just like the speedometer. The answer is to have the Snapdragon 820 run two OSes by way of virtualization, with Android working the middle infotainment display screen and another OS working the gauge cluster show. Android can nonetheless ship the gauge cluster a UI overlay for issues like media information and Google Maps data, however the speedo is off-limits.

Resurrecting the Snapdragon 820 for a contemporary product is an fascinating proposition for Qualcomm. On smartphones, Qualcomm’s product help is commonly cited as a serious barrier for the longevity of Android telephones. The Snapdragon 820 would have supported one thing like three main Android variations, so Android 6, 7, and eight. Qualcomm would have shut down help someday round 2019, precisely when the Snapdragon 820-based third-generation automotive chip was introduced. So whereas Qualcomm would have killed your cellphone, it doesn’t look like Android improvement for this chip ever truly stopped. The Polestar 3 will most probably begin with Android 11 or 12, and help might want to proceed for years, though the corporate would not need to go that work on to smartphones.
Immediately, Qualcomm has a public help timeline for cellphone chips: three years of main OS updates and 4 years of safety updates. When requested if there was an identical plan for automotive help, Qualcomm mentioned it might help automotive chips for longer than cellphone chips, however the firm would not provide specifics.
Shoving a smartphone chip in a automotive provides Qualcomm a fast solution to get to market, since telephones are at the moment its largest market. However the answer just isn’t supreme. Smartphone chips are designed totally across the measurement and energy restrictions of a smartphone, none of which exist in a automotive. A automotive is large. Your entire ground is a battery. The cooling could be as large as you want it to be. Qualcomm is working into the identical drawback many firms within the trade are working into: the largest ARM chips are nonetheless largely simply the smartphone chips. Apple is setting the pattern by scaling up ARM to desktop and laptop computer computer systems, however it might do this as a result of it has a customized chip-design division. Most different firms do not. Qualcomm is engaged on getting there although, and it plans to start out designing extra highly effective ARM chips for laptops (and automobiles?) sooner or later.
