Connected Vehicles

[Audio] Connected Vehicles Vehicles which are connected over wireless networks to nearby devices are known us Connected Vehicles. They connect to a network to enable communication between vehicles and infrastructure. This is mainly used for passing on important communication or alerting others on events. This uses vehicle to roadside unit communications also called as V2X communications..

[Audio] The main objective of this application is Enabling vehicles to connect to wireless networks that connects to devices or infrastructure outside the vehicle. This is done through devices called Telematic Control Units..

[Audio] TCU refers to the embedded system onboard on a vehicle. TCUs are controlled by Telecom providers and specific telecom providers' support certain TCUs only. This wirelessly connects the vehicle to cloud services or other vehicles nearby. This uses V2X communication over a telecom network. It provides in vehicle connectivity via wifi or Bluetooth. This helps in implementing the eCall feature in vehicles..

[Audio] The solution is designed assuming that the automobile company has SAP ERP implemented in it and has Azure as its Cloud Service provider. The process flow from installation of Telematic control unit in the Assembly Line till the eSim detail updation in SAP is explained in this slide..

[Audio] Multiple technical developments are needed to ensure that this feature is working fine in SAP ECC landscape. In Azure Application Programming Interfaces( API) are created for activating eSim and sending vehicle details to SAP. In SAP Process Integration, interface is created to transfer data between Azure and SAP ECC system. In SAP, ABAP enhancement is done to ensure that the eSim number is updated to the production order. This is done to ensure that same eSim number is not Assigned to another vehicle and the vehicle can be tracked uniquely with the Sim number..

[Audio] The main benefits of this application are. Connected vehicle feature enabled through this application. Enables Emergency Call feature in vehicles which automatically dials emergency numbers in case of road accidents. This also wirelessly sends airbag deployment instruction to the vehicle. Telecom providers track the vehicles continuously through eSim enabling them to track in in case of theft. This also allows telecom providers to send over the air updates to software..

[Audio] Technical developments mentioned can be built as an independent application and can sold for multiple automobile vendors. This feature can be extended to commercial and cargo vehicles in the future in addition to passenger cars. New markets are opting for the Emergency Call feature which can use this prebuilt application..

Tcu /activate API policy validates certificate thumbprint to proceed further. Connected Car orchestrator LA is triggered if thumbprint is validated successfully. Based on the Market, Etisalat or Vodafone LA is invoked. Car color is retrieved from SAP via GET API Post activating SIM, SFTP LA is invoked where CSV file is generated. SAP PO endpoint is called to encrypt tcu key with RSA encryption. Generated CSV file is transferred to SAP PO and finally dropped in SFTP server.
