The problem that we are trying to solve is how an application on telematics platform can utilize multiple network interfaces available in different electronic control units (ECU’s) in the vehicle efficiently. Although this appears to be a similar problem facing the application on the smartphone, it differs considerably in many scenarios and needs. When the vehicle is in motion, network interface availability is transient; this poses unique challenges for utilizing the available networks effectively. And also vehicle employs a power mode strategy to ensure that the battery is not drained, implying time available after ignition-off is limited. To address seamless connectivity for automotive platforms that are generally supported with multiple network interfaces, we are considering Multipath TCP (MPTCP).

SmartDeviceLink (SDL) is open-source software that connects the vehicle’s infotainment system to mobile applications. SDL includes an open-source software development kit (SDK) that enables a smart-device to connect to the vehicle’s human-machine interface (HMI), read vehicle data, and control vehicle sub-systems such as the audio and climate systems. It is extensible, so other convenience subsystems or brought-in aftermarket modules can be added. Consequently, it provides a platform for cyber-physical systems that can integrate wearables, consumer sensors and cloud data into an intelligent vehicle control system. As an Open Innovation Platform, new features can be rapidly developed and deployed to the market, bypassing the longer vehicle development cycles. This facilitates a channel for rapid prototyping and innovation that is not constrained by the traditional process of automotive parts development, but is rather on the timeline of software development.
