DEVICE DESCRIPTION General Motors’ (“GM”) Vehicle Cockpit Unit (VCU) 1.0 is a technology upgrade for the previous generation GM Cockpit ECU platform (“Info 3.x”). The GM Vehicle Cockpit System (“VCS”) is responsible for the user experience in the cockpit of GM vehicles. The VCU is a silver box solution providing interfaces to displays, speakers, sensors and optional components of the VCS. The VCU, provides the following capabilities: • Vehicle and infotainment related information to the slim-IPC, ICS, auxiliary, HVAC, and HUD displays. This includes processing of various vehicle camera viewing streams to certain displays. • Audio capability that includes processing various radio broadcasts to the vehicle, voice capturing using microphone inputs, user media playback via phone or USB, and integrating audio enhancements (for example ANC) using microphone inputs. • Wi-Fi, Bluetooth, and GPS connectivity. • Various analog and digital I/O, including but not limited to switches, HUDs, sensors, etc. It supports two major GM electrical vehicle architectures (called “Global B” and “CLEA”) and is offered in two major product variants: “MID” and “HIGH”. In terms of regional support, a distinction is made between North America (“NA”), China (“CN”) and RestOfWorld (“RoW”) configurations. The VCU hardware is based on a two-processor approach where Qualcomm’s latest ARM-based automotive system-on-chip (SoC) family 8195 (High) and 8155 (Mid) acts as core computing element and Renesas Electronics' latest automotive micro-controller RH850F1KM/KH (Vehicle Interface Processor, VIP) is used for real-time processing needs. The VCU software architecture is mainly based on 3 run-time environments (called SW domains): • Running on VIP: o AUTOSAR OS as real-time processing system • Running on SoC: o Blackberry Hypervisor V2.x based on QNX7.x to realize a host environment and guest environment as virtual machine o Host: QNX7.x operating system o Guest: Android system based on Linux kernel The VCU can determine its geographical location: • In the VCUNH1 the positioning information is provided by an external device, the Telematics Module.
