Telematics eCall Plug | TEP


The Fast Track to Customer Relationship Improvement

Telematics eCall Plug is a smart sensor device designed for crash detection and analysis of driving behavior. The easy-to-apply retrofit solution plugs into the 12V outlet of any passenger car.

Benefit from Bosch’s best in class technology and make use of various functionalities integrated in a small frame size:

  • eCall functionality & driving behavior determination
  • eCall functionality only
  • Driving behavior determination only


eCall Functionality


On the one hand, the retrofittable eCall functionality acts as an intelligent guardian angel. The hyper-accurate integrated acceleration sensor and a built-in microcontroller detect the severity of an accident. If the impacts are strong enough, the eCall functionality sends information to a smartphone app via Bluetooth. Then, drivers get immediate help through an emergency call.


Driving Behavior Determination

On the other hand, the device gives precise insights to improve driving behavior. TEP generates driving dynamics data based on acceleration, braking, and cornering events and transmits it to the driver´s smartphone via bluetooth.

Driving event data and event based GPS information is sent to the back end of the business customer. There, the data can be analyzed and processed together with additional information according to the individual requirements of the business partners.
