In general, the system 100 provides electrical and software architecture for vehicle applications, leveraging modern wired/wireless communication and embedded/cloud computing technologies. As shown in
The connected compute center 110 is a computing device and an example of a connected compute controller (also called compute controllers) that supports mixed I/O from different (e.g., separate and/or independent) domains and functions across the zone I/O controllers 140. The connected compute center 110 can comprise one or more compute modules, which are connected to the same backbone 130 as the zone controllers. In turn, a physical separation among domains of the system 100 are no longer separate, as virtual machines and applications from different domains execute on the same connected compute center 110. For instance, the connected compute center 110 supports a mixed environment in terms of software functions. The connected compute center 110 can include one or more adapters (e.g., hard disk controllers, network adapters, graphics adapters, etc.) that interconnect and support communications between the processor 111, the system memory 112, the database 114, and other components of the system 100 (e.g., peripheral devices on the backbone 130). In one or more embodiments, the one or more adapters can be connected to one or more I/O buses that are connected to the system bus via an intermediate bus bridge, and the one or more I/O buses can utilize common protocols, such as the Peripheral Component Interconnect (PCI).
The processor 111, which can include one or more central processing units (CPUs), can be referred to as a processing circuit, microprocessor, or computing unit that is coupled via a system bus to a system memory 112 and various other components. The system memory 112 can include read-only memory (ROM) and random access memory (RAM). The ROM is coupled to the system bus and may include a basic input/output system (BIOS), which controls certain basic functions of the system 100. The RAM is read-write memory coupled to the system bus for use by the processor 111. The accelerator 113 is an example of a specialized processor (e.g., the processor 111), such as a graphics processing unit or the like.
The database 114 is an example of a tangible storage medium readable/executable by the processor 111. The database 114 stores software and data. The software is stored as instructions for execution on the system 100 by the processor 111 (to perform process, such as the process flows 200 and 400 of
The virtual platform 120 is a simulated hosting environment executed by the connected compute center 110 to support operations of virtual machines therein. A virtual machine is an emulation of a computer system or architecture that provides functionality through specialized software. The braking virtual machine 121 is an example of a virtual machine for managing/implementing braking operations of the vehicle, along with associated I/O braking devices (e.g., brake actuators, speed sensors, and the like of a vehicle). The body virtual machine 123 is an example of a virtual machine for managing/implementing body operations of the vehicle, along with associated I/O body devices (e.g., doors, windows, trunk, hood, mirrors, and the like of a vehicle). The lighting virtual machine 125 is an example of a virtual machine for managing/implementing lighting operations of the vehicle, along with associated I/O lighting devices (e.g., head lights, floor lights, fog lights, brake lights, dashboard lighting, and the like of a vehicle). The steering virtual machine 127 is an example of a virtual machine for managing/implementing steering operations of the vehicle, along with associated I/O steering devices (e.g., steering column, steering position sensors, steering relays, and the like of a vehicle). The active safety virtual machine 129 is an example of a virtual machine for managing/implementing active safety operations of the vehicle, along with associated I/O active safety devices (e.g., seat belt sensors, seat belt retractors, airbags, and the like of a vehicle).
The backbone 130 is a network infrastructure including wired and wireless connection mediums that support communications between the connected compute center 110 and the zone I/O controllers 140. In accordance with one or more embodiments, the backbone 130 can be an Ethernet backbone providing local area network (LAN) and wide area network (WAN) capabilities for the communications of the system 100. The Ethernet backbone can be a one Gigabits per second network that enables seamless transmissions of I/Os around the system 100.
The zone I/O controllers 140 can be chips, computing cards, or stand-alone devices (thereby including at least a processor and a memory) that interface with a peripheral devices, such as the I/O devices discussed herein. Examples of the zone I/O controllers 140 include gate I/O zone modules (also called a zone gateway or a zone module) that provide different domains and functions for the I/O devices. The zone I/O controllers 140 are connected to the backbone 130. The zone I/O controllers 140 make inputs and outputs available to the virtual machines and the applications executing on the connected compute center 110. In accordance with one or more embodiments, the zone I/O controllers 140 can support and host, via the backbone, a wide range of vehicular functions of mixed criticality. For instance, zone I/O controllers 140 provide a gating function (e.g., a main communication interface) for data communicated to and from the I/O devices, along diagnostic and time synchronization operations.
The I/O devices (represented by dashed-block 150) include functions and/or features of the vehicle, which are managed and operated by one or more virtual machines of the the virtual platform 120 (e.g., the virtual platform 120 as executed by the connected compute center 110 support operations of the I/O devices by driving I/O across the backbone 101 and through the zone I/O controllers 140). In practice, the I/O devices include transducers that convert variations in a physical quantity, such as speed or pressure, into an electrical signal or vice versa. Further, the I/O devices can also be output devices such as lights, light emitting diodes, speakers. The I/O devices can also communicate via any interface, such as a controller area network (CAN), a local interconnect network (LIN), a direct I/O interface, an analog to digital (A/D) interface, a digital to analog (D/A) interface, or any other interface specific to the input/output. Each I/O device is connected to a zone I/O controller 140 based on proximity to that zone I/O controllers 140, regardless of the interface used by that I/O.
As described herein, examples of the I/O devices include I/O braking devices (e.g., brake actuators, speed sensors, and the like of a vehicle). I/O body devices (e.g., doors, windows, trunk, hood, mirrors, and the like of a vehicle). I/O lighting devices (e.g., head lights, floor lights, fog lights, brake lights, dashboard lighting, and the like of a vehicle); I/O steering devices (e.g., steering column, steering position sensors, steering relays, and the like of a vehicle); and I/O active safety devices (e.g., seat belt sensors, seat belt retractors, airbags, and the like of a vehicle).

The features and the functions (e.g., the I/O devices) are distributed throughout the vehicle and connected to the zone I/O controllers 140 based on being located in a (specific/particular) region of the vehicle and local to a particular zone I/O controller 140.
In general, the architecture 300 provides electrical and software architecture for vehicle applications, leveraging modern wired/wireless communication and embedded/cloud computing technologies. As shown in
The architecture 300 includes an Ethernet backbone 330 including a network infrastructure including wired and wireless connection mediums that support communications between the connected compute center 310 and a plurality of zone modules 340 of the architecture 300 (e.g., the Ethernet backbone 330 communicatively couples connected compute centers 310 and the plurality of zone modules 340). The Ethernet backbone 330 can be a one Gigabits per second network that enables seamless transmissions of I/Os around the architecture 300.
Note that, in accordance with one or more embodiments, five distinct zone modules 340.1, 340.2, 340.3, 340.4, and 340.5 are shown with respect to specific areas or regions of the vehicle 301. For example, the zone modules 340.1 can be located on a left-front region of the vehicle 301; the zone modules 340.2 can be located on a right-front region of the vehicle 301; the zone modules 340.3 can be located on a left-rear region of the vehicle 301; the zone modules 340.4 can be located on a left-rear region of the vehicle 301; and the zone modules 340.5 can be located on a front-center region of the vehicle 301. In this regard, I/O devices local to a particular one of the zone modules 340 are connected thereto (e.g., inputs and outputs are allocated to a closest zone module, instead of to specific microcontrollers per function/feature as in the conventional automotive electrical architectures). In turn, automotive functions and features execute on the connected compute center 310 and communicate with zone modules 340 via the Ethernet backbone 330.
For instance, a speed sensor S1, a brake actuator B1, and a window sensor W1 are I/O devices connected to the zone module 340.1, along with the I/O device of a steering column sensor D. Further, a speed sensor S2, a brake actuator B2, and a window sensor W2 are I/O devices connected to the zone module 340.2; a speed sensor S3, a brake actuator B3, and a window sensor W3 are I/O devices connected to the zone module 340.3; and a speed sensor S4, a brake actuator B4, and a window sensor W4 are I/O devices connected to the zone module 340.4. In addition, an engine sensor E is an I/O device connected to a zone module 340.5, while a radar sensor R and cameras C1, C2, C3, C4, and C5 are I/O devices connected directly to the Ethernet backbone 330.
The architecture 300 also includes a cloud service 360, which includes processors (identified by CPUs), interfaces (identified by I/O), accelerators (identified by Acc), and a database (identified by D). The cloud service 360 connects wirelessly 361 to the connected compute center 310 to provide remote compute resources for offloading certain functions from the vehicle 301. That is, the architecture 300 can exploit vehicle connectivity to offload applications that traditionally run on an embedded microprocessor. Further, the architecture 300 can determine and evaluate latency requirements when making a decision as to whether or not a vehicle function or feature shall execute in the cloud. The technical effects and benefits of this offloading include enabling for simpler management than conventional automotive electrical architectures, reduced on-board computing requirements, flexibility, and reduced time-to-market of new features.
The cloud service 360 can provide a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may be deployed as a Software-as-a-Service (SaaS), a Platform-as-a-Service (PaaS), or an Infrastructure-as-a-Service (IaaS).

At block 420, the architecture 300 executes diagnostics and packaging of the data to produce packaged data. Based on which element of the architecture 300 reads the data, that element can perform the diagnostics and packaging. For instance, after the zone module 340.3 reads tire speed data from the speed sensor S3, the zone module 340.3 can diagnose and package the tire speed data so that it can be sent across the Ethernet backbone. At block 430, the architecture 300 forwards, through the Ethernet backbone 330, the packaged data. Note that if the connected compute center 310 directly reads data from an I/O device, block 430 may be merged with blocks 410 and 420 and/or the packaging of the data may be avoided.
At block 440, the connected compute center 310 executes zone controlling to determine process actions and render corresponding packaged outputs. That is, in response to receiving the packaged data, the connected compute center executes one or more of the applications 321, 322, and 333 of the virtual platform 320 to drive decision on operating the I/O devices of the architecture 300. The decisions themselves are implemented as commands or instructions, which are rendered as the packaged outputs. At block 450, the architecture 300 forwards, through the Ethernet backbone 330, the packaged outputs. At block 460, architecture 300 executes diagnostics and un-packaging of the packaged outputs to render outputs.
For instance, after the zone module 340.3 reads commands or instructions from the connected compute center 310 for the braking actuator B3, the zone module 340.3 forwards an instruction to drive the braking actuator B3 as an output. At block 470, the I/O device implements the outputs received from the other items of the architecture 300.
If the connected compute center 310 directly provides outputs to an I/O device, blocks 440 and 450 may be merged and/or the un-packaging of the commands or instructions may be avoided. Note that blocks 420 and 460 can be viewed as sub-operations of block 260 of
