USBware for the Automotive Industry
USB Software: Automotive Devices
Overview
USBware for Automotive was designed to support the specific needs of automotive device manufacturers.
USBware enables the implementation of USB connectivity in automobiles, allowing in-car multimedia systems
to communicate directly via USB with MP3 players, iPods, thumb drives and other USB enabled devices.
With the wide spread of USB connectivity, many new use-cases require USB implementation inside automobiles
and other vehicles. Example use-cases include:
- Multimedia systems:
- Connecting USB flash drives within the car and enabling end-users to manage, use or
transfer their pictures, audio or video files onto their in-car infotainment systems or radios
- Streaming digital audio or video content using PMPs, MP3 or MP4 players connected to the car stereo
- Providing high quality audio playback and steaming from Apple iPod and iPhone devices via Jungo's
high quality and proven embedded USB audio drivers
- Connectivity Box
- Offering wifi or wireless connectivity by enabling vehicle owners to insert USB wifi or USB wireless
dongles, and easily connect to their preferred wireless networks
- Handsets:
- Connecting mobile handsets into embedded hands free systems
- Streaming media to and from audio systems
- Synchronizing mobile content with users' in-car databases (pictures, contacts, calendars etc.)
- Navigation systems:
- Uploading maps and other data onto the navigation system
- Upgrading firmware of the navigation system
- Testing:
- Logging test data from the car to the PC
- Uploading test suites and firmware to the car
- Configuration:
- Storing driver-specific configuration data (such as chair positioning, radio tuning, etc.) on flash drives and configuring the
automobile automatically using this data
The above use-cases require robust and extensive USB implementation, ranging from device to host and including
class drivers such as USB mass storage and audio that feature high speed streaming of data.
Jungo provides a complete embedded USB stack required to implement USB connectivity in automotive devices.
USBware features scalable architecture, supporting variety of off-the-shelf USB controllers and
operating systems, in addition to supporting non-standard controllers and proprietary operating systems.
This enables automotive device manufacturers to select the architecture best suitable for their device,
and furthermore enables existing devices to easily add USB connectivity in future designs.
