Wireless Smart Car Keys: The Future Or Dumb Idea?

Wireless Smart Car Keys: The Future Or Dumb Idea?

In the current generation of keyless entry for cars, a smart key system disengages the immobilizer and activates the ignition without inserting a key in the ignition. The system uses LF (low frequency, 125 kHz) and RF (radio frequency, >300 MHz).

The idea hit as of late while talked with Broadcom official Tom Ramsthaler, in charge of item promoting of remote connectivity. In examining the organization’s up and coming 802.11ac/Bluetooth Low Energy (LE) combo chip, Ramsthaler disclosed to me what he imagines as in-vehicle applications empowered by Bluetooth LE.

Nissan WatchHe discussed the Nissan Watch, divulged at the Frankfurt Auto Show a month ago. The smartwatch, utilizing a Bluetooth LE association, assembles telemetry information from an auto with the goal that it can demonstrate the driver the auto’s effectiveness data, for example, fuel utilization while likewise following execution. The Nissan Watch likewise monitors certain parameters of driver well being, similar to heart rate in a road turned parking lot.

Alright, somewhat fascinating. In any case, scarcely the mass business sector item that will incite each auto maker to grasp Bluetooth LE, it is thought. In any case, Ramsthaler said impromptu that Bluetooth LE would be valuable as a keen auto key.

NXP, outfitted with the lion’s offer in the keen auto key business sector, had been intuition thusly. NXP thought of a solitary chip answer for multi-capacity auto keys utilizing Near Field Communication (NFC) innovation. The thought is for keys to interface with outer NFC-agreeable gadgets, for example, cellular telephones, tablets, and portable PCs. Reporting the item, called KEyLink Lite, NXP discussed potential “shrewd” key applications including auto discoverer, course organizer, and auto status/administration information administration.

Along these lines, now that Broadcom is going to the car market with Bluetooth LE chips, will we see a NFC versus Bluetooth LE fight blending in the keen auto key business sector?

On the other hand even better, will there be a day when we can get rid of our auto keys and flip open an auto entryway basically by waving the telephone?

Executive of worldwide car hone at Strategy Analytics, concurred that opening an auto with a smartphone is conceivable. In any case, he forewarned: “The issue is that many individuals go inside an auto to charge their smartphones. Consider the possibility that your smartphone as of now came up short on battery. You can’t open your auto entryway!”

 

Applying NFC in a smartphone to the car security system is certainly feasible. But the driver still needs to walk up to a car and physically open the door — unless the smartphone is also integrated with an LF/RF-based keyless entry system.

 

Freeman explained, “With a smartphone, it’s a two-step process. In contrast, the smart car key you use today can remotely flip a car open — instantly,” without fiddling with your smartphone first.

 

But let’s be clear: The idea of unlocking and locking the car and then starting the ignition with a phone has haunted the minds of some carmakers, such as Hyundai.

 

NFCBy using an embedded NFC tag in the car, Hyundai has designed a system that allows owners to unlock a vehicle, start the engine, and link up to the touchscreen with a quick swipe. The Korean automaker showed earlier this year what the company calls its “Connectivity Concept” in a demonstration i30 hatchback car.

 

So, the idea of the smartphone as your car key has been percolating for a few years, and it has gotten some attention from carmakers. Can a Bluetooth LE be that key?

 

One might say: Why not?

 

The first step in proving the feasibility of this concept is to make sure there is absolutely no EMC interference between a Bluetooth-based smart car key and the electronics inside the vehicle. Perhaps more important, Bluetooth LE requires power (albeit low energy). NFC connectivity “does not require a power supply in the key, hence does not affect the key’s battery lifetime,” according to NXP’s spokesperson. “Setting up a connectivity link is done by a touch and would not require an exchange pairing credential upfront.” In sum, NFC allows carmakers to focus on convenience and security.

 

Even assuming that either wireless technology — NFC or Bluetooth — works fine as a smart car key, technology suppliers need to clear one more hurdle.

 

NXP’s Freeman explained that for a carmaker, the branded car key establishes the first and the most significant physical and tactile contact with car owners. Automotive companies might not be so eager to give up that precious branding opportunity to a smartphone — which bears no automotive brand.

 

for the time being, the NFC vs. Bluetooth LE battleground is likely to be focused more on connecting a smart car key with a smartphone (or any smart wearable device), rather than a smartphone replacing a car key.

 

According to NXP, the company’s multi-function car key using NFC is “one member of a complete new product family designed for Smart Access solutions.” The product family debuts in the market with model year ’13 vehicles.
