Windows Automotive

Windows CE for Automotives (WCEfA) based on Windows CE, adapted for the specific requirements of the automotive industry for use in motor vehicles. This requirements are parallel access to the hardware, more stringent standards to the stability, security and response times. It supports a variety of processor architectures. Car manufacturers like for example Ford, Fiat and Kia integrate this operating system into different car models for offering services such as navigation, entertainment, communications and more.

Windows Automotive 5.0 based on the Windows CE 5.0 operating system. By AUITK (Automotive User Interface Toolkit), the user interface can be efficiently adapted to the particular vehicle model. The Automotive System Toolkit (AST) provides the tools to optimize the performance by CPU management, diagnostics and fault monitoring.

Microsoft Auto 3.0 based on the Windows Embedded CE 6.0. It offers voice-based interaction with the user, the use of USB storage media, locating by GPS and secure updates of the operating system and software. Mobile devices can be connected via Bluetooth.

It is used for the technologies of Ford SYNC, Fiat Blue&Me and Fiat Blue&Me MAP. Ford SYNC since autumn 2007, a build-in communication and entertainment system for 12 different car models from Ford, Mercury and Lincoln. From end of 2009, Ford plans to equip all car models with SYNC. As hardware an Advanced RISC Machine (ARM) 11 processor, 64 MB RAM and 256 MB of flash memory is used. The USB port can be used to install updates of the device support.

Fiat use Microsoft Auto for the Blue&Me infotainment system and Blue&Me MAP navigation system. With the additional program EcoDrive the driver can even record his driving behavior onto a USB stick and evaluate it later for economical reasons on the computer.

Microsoft Auto 3.1 setzt auf das aktualisierte Betriebssystem Windows Embedded CE 6.0 R2. Es enthält ein neues Sicherheitsmodell für Anwendungen und das Betriebssystem. Die Signierung von Programmcode soll die Ausführung von unsignierten Programmen verhinden. Die Entwicklungs-Tools umfassen den Platform Builder 6.0, Visual Studio 2005, Microsoft Auto 3.1 Platform Development Kit und die Referenz-Hardware.

Reference hardware:
  • CPU: Freescale i.MX31, 16/32 bit RISC processor, with each 16 KB instruction and data cache
  • 128 KB second level cache
  • Security controller, including secure RAM and security Monitor
