Assisting to Develop Modern In Vehicle Infotainment Systems

Wireless in-vehicle applications remain an area of intense interest for many in the automotive industry. In addition, global vehicle sales are increasing and it is forecast that sales in 2012 will reach over 78 million cars sold.

Clarinox worked with Sumitomo Wiring Systems Australia on the Bluetooth subsystem of an in-vehicle infotainment system. 

This is an example of Clarinox providing the technology to support innovation in the automotive industry. The Clarinox experience in wireless product development, combined with the Clarinox portfolio of wireless protocols, software tools and hardware reference designs place us in a unique position to ensure the success of connectivity components of In-Vehicle Infotainment system developments. 

By working closely with the project stakeholders Clarinox helped to make this project a success. 

Clarinox Role 

ClarinoxBlue stack, Clarinox debugging and protocol analyzer were used extensively to provide high visibility of the communications occurring throughout the operability test phase. This provided the information required to debug the IVI code and also mitigate interoperability issues with third party devices. 

This project demonstrated the simultaneous running of the ClarinoxBlue Bluetooth automotive profiles (A2DP, AVRCP, HFP PBAP and MAP) proven on a FreeScale i.MX31 ARM Cortex based hardware running QNX operating system. 

Additionally Clarinox role included assistance with the qualification process. 

Outcome for Client 

The visibility provided by the Clarinox tools enabled the detection of non-compliant behaviour of third party Bluetooth devices The work from Clarinox contributed to the success of the interoperability testing leading to overall project acceptance from the end client. 

Future Plans 

The ability to run simultaneous profiles, the Clarinox support for additional wireless protocols (e.g. WiFi &/or BLE) within the same framework opens up numerous new connectivity opportunities. An example of the multiple simultaneous use case is shown in Figure 1. Sensor feeds via BLE e.g. keyless entry, driver health signs, auto detection of passengers for seat belts, tyre pressure measurement, wireless reverse camera are some of the potential future extensions.
