The development of new energy vehicle infotainment systems is characterized by various types of central control units, ensuring that functionalities can be updated regularly through over-the-air (OTA) updates. However, it's only a matter of time before the hardware lag behind the software, causing potential issues. For instance, electronic rearview mirrors, which heavily rely on onboard processing, may experience frame drops if the hardware-capacity does not suffice, posing significant safety risks. In contrast, carplay, carlife, and hicar, which primarily rely on the smartphone for calculations, are more reliable and potentially more secure alternatives.
