ECall Telematics Solution

TT provided expertise in IoT technology to support TRL (the Transport Research Laboratory) to develop proposed technical requirements and test procedures for the type-approval of eCall in-vehicle systems. eCall technology automatically communicates with the emergency response services in the event of a road accident.

TT provided TRL with telematics units and technical support in order to develop an appropriate set of test procedures for the eCall systems. The technology and support from TT formed an integral part in the development of proposed test procedures, which were developed and put forward by TRL to the European Commission (EC) in preparation of the mandatory European roll-out of eCall systems in 2018.

As part of the project TRL developed draft requirements and test procedures for seven technical aspects which include Resistance of eCall systems to severe crashes (sled test), Full Scale impact test, Crash resistance of audio equipment, Co-existence of third party services (TPS), Automatic triggering mechanism, In-vehicle system self-test, and Privacy and data protection.

Technical expertise and 12 telematics units provided by TT were used for experiments in the dedicated deceleration sled test element, and operability verification test procedures which set out to measure the mechanical resistance of eCall systems to severe crashes at accelerations up to 100 g. The samples included the telematics control module (ECU), containing the printed circuit board with GSM and GNSS modules, SIM card holder and SIM card, capacitors and other electronic components.
