Cars are turning into real ones devices able to receive updates that introduce new functions or improve existing ones. After Tesla, more and more manufacturers are implementing the ability to be updated remotely in their new cars. This is the case of Polestar, which offers support to OTAs within Polestar 2. And this car has received a interesting update.
Although still in beta, the new one arrives Polestar Digital Key function. In other words, it will be possible to open the car using the smartphone as a digital key. To ensure maximum reliability and safety, the vehicle has ben 18 Bluetooth sensors to be able to communicate with the smartphone. The sensors positioned around the car detect the approach of the associated mobile device.
Within two meters, sensors detect the location of the device, allowing you to open the doors, tailgate or charging flap. Starting the car requires the paired device to be placed inside the vehicle to protect it from inadvertent starting. The digital key it is encrypted within the Polestar app on the smartphone and the manufacturer was able to verify the high security of this system which is immune from the “relay” attacks that can affect cars equipped with a keyless system. In this case, in fact, an encrypted Bluetooth signal is used and only when the smartphone and car are at a useful distance. The classic remote controls, on the other hand, work on radio frequency.
The news did not end there. Following the update, the Polestar app now allows you to view some information on the status of the vehicle such as the battery level. It will also be possible to start the air conditioner and lock the car doors remotely. More features will come in the future.
Finally, among the other most interesting innovations, the possibility of being able to preheat the battery to improve the efficiency and therefore the autonomy of the car.
