A supplier of eSIM chips, Infineon, said that car manufacturers like Daimler are using the firm’s eSIM security controllers for the emergency call feature – called eCall – that will be mandatory for all new car and light commercial vehicle models in the European Union from 31 March 2018. It will, therefore, be integrated in future in an estimated 20 million new vehicles annually, states the announcement.
The aim of the eCall system is to shorten the time between an accident and the arrival of the emergency services by up to 50 percent throughout Europe, and reduce the number of fatalities on the road by around 10 percent. The automatic eCall can also prevent serious accidents from going unnoticed. In the event of an accident, eCall is used to independently send an emergency call to the emergency call center via the mobile network. Details such as the location, the precise time of the accident, the number of passengers and the type of fuel are transmitted
The eSIM works much like a SIM card in mobile phones, but is much smaller and more robust.
Regarding the advantages of eSIMs, Infineon explains: “Only eSIMs meet the special quality requirements in the automotive sector (AEC-Q100): They are robust, durable and resistant to large fluctuations in temperature. They are also integrated in cars before they leave the manufacturer and can be managed remotely. One big advantage is that neither the car manufacturer nor the driver are tied to a specific mobile provider.”
Infineon boasts that its SLI 97 security controllers are specifically tailored to the tough environmental conditions in automotive applications and meet the automotive industry’s high-quality standards (AEC-Q100).
The company adds: “These .security controllers feature an extended temperature range of -40° to 105°C and high resilience. They are also equipped with a SOLID FLASH memory with a capacity of up to 1 MB. Hardware-based crypto coprocessors provide the required security by enabling the common encryption mechanisms.”
