CES – Bosch unveils Telematics eCall Plug

Bosch Connected Devices and Solutions is to unveil its Telematics eCall Plug (TEP), a retrofit plug-in sensor device at CES 2018

Bosch Connected Devices and Solutions is to unveil its Telematics eCall Plug (TEP), a retrofit plug-in sensor device at CES 2018.

The device delivers event data such as driving behaviour and crash detection for telematics, fleet management and insurance applications. The smart sensor device plugs into a standard 12V car cigarette lighter socket.

Data from the TEP enables usage-based business models, for example, for insurance purposes; however, it is also set up to be adopted by fleet operators and automobile clubs.

The device’s eCall function registers car crash severity and can help to save lives by enabling faster emergency response times. 

Data-based insurance:

The TEP uses built-in sensors and microcontroller to accurately track driving behaviour parameters such as acceleration, braking and cornering forces, then transmits this data to the driver’s smartphone via Bluetooth. 

The collected data can be used to help improve safety by identifying aggressive driving behaviour and enables more personalised behaviour-based insurance, by rewarding safe drivers with discounts on premiums.

The data can also help insurers to identify and reduce fraudulent claims, while fleet operators can use the acquired data for monitoring driving behaviour.

Improving automotive safety:

The TEP’s eCall function uses acceleration sensors and embedded algorithms to detect car accident events and their severity. It communicates with the driver’s smartphone via Bluetooth. Accident alerts are sent to a call centre via smartphone.

The centre can subsequently automatically and quickly contact the emergency response services – speeding up response times and potentially saving lives. In less extreme situations, the call centre can trigger roadside assistance.


The TEP has three configurations: the eCall function only, the driving behaviour data only, or both functions. It plugs into the standard 12V DC car outlet. There is no connection to the car’s IT infrastructure, where any risk of hacking is eliminated.

Bosch also offers a Software Development Kit (SDK) for the TEP, which addresses Service Partner needs for the development of a retrofit automotive telematics solution.

The SDK supports both Android and iOS operating systems, using the benefits of the Bluetooth Low Energy (BTLE) platform.
