<table id="amazon-polly-audio-table"><tbody><tr><td id="amazon-polly-audio-tab"><p></p></td></tr></tbody></table><p>Today we announce the general availability of <a href="https://aws.amazon.com/iot-fleetwise&quot;&gt;AWS IoT FleetWise</a>, a fully managed AWS service that makes it easier to collect, transform, and transfer vehicle data to the cloud. Last AWS re:Invent 2021, we <a href="https://aws.amazon.com/blogs/iot/collecting-vehicle-data-more-efficiently-with-aws-iot-fleetwise-2/&quot;&gt;previewed&lt;/a&gt; AWS IoT FleetWise, heard customer feedback, and improved features for <a href="https://aws.amazon.com/blogs/iot/generating-insights-from-vehicle-data-with-aws-iot-fleetwise-part1/&quot;&gt;various use cases</a> of near-real-time vehicle data processing.</p><p>With AWS IoT FleetWise, automakers, fleet operators, and automotive suppliers can take the complex variability out of collecting data from vehicle fleets at scale. You can access standardized fleet-wide vehicle data and avoid developing custom data collection systems, or you can integrate AWS IoT FleetWise to enhance your existing systems. AWS IoT FleetWise enables intelligent data collection that sends the exact data you need from the vehicle to the cloud. You can use the data to analyze vehicle fleet health to more quickly identify potential maintenance issues or make in-vehicle infotainment systems smarter. Furthermore, you can use it to train machine learning (ML) models that improve autonomous driving and advanced driver assistance systems (ADAS).</p><p>For example, electric vehicle (EV) battery temperature is a critical metric that should be continuously analyzed for the entire vehicle fleet. In order to avoid costly continuous data ingestion, you may want to optimize the data collection by setting a threshold on EV battery temperature. The results of this analysis would be provided to the automaker’s quality engineering department, enabling fast assessment of the criticality and possible root causes of any issues identified at certain temperatures. Based on the root cause analysis, the automaker can then take short-term actions to support the driver affected by the issue, as well as midterm actions to improve vehicle quality.</p><p><strong class="c4">How AWS IoT FleetWise Works</strong>AWS IoT FleetWise provides a vehicle modeling framework that you can use to model your vehicle and its sensors and actuators in the cloud. To enable secure communication between your vehicle and the cloud, AWS IoT FleetWise also provides the AWS IoT FleetWise Edge Agent application that you can use to download and install in-vehicle electronic control units (ECUs) such as the gateway, in-vehicle infotainment controller, etc. You define data collection schemes in the cloud and deploy them to your vehicle.</p><p><img class="aligncenter size-full wp-image-63415" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2022/09/22/2022-iot-fleetwise-0-how-it-works.jpg&quot; alt="" width="2276" height="1034" /></p><p>The AWS IoT FleetWise Edge Agent running in your vehicle uses data collection schemes to control what data to collect and when to transfer it to the cloud. Data collected and ingested through AWS IoT FleetWise Edge Agent software goes directly into your <a href="https://aws.amazon.com/timestream/&quot;&gt;Amazon Timestream</a> table or <a href="https://aws.amazon.com/s3&quot;&gt;Amazon Simple Storage Service</a> (Amazon S3) repositories via <a href="https://aws.amazon.com/iot-core/&quot;&gt;AWS IoT Core</a>.</p><p><strong class="c4">AWS IoT FleetWise Features</strong>To get started with AWS IoT FleetWise, you can register your account and configure the settings via the <a href="https://console.aws.amazon.com/iotfleetwise/home&quot;&gt;AWS console</a>. AWS IoT FleetWise automatically registers your AWS account, IAM role, and Amazon Timestream resources.</p><p>The Edge Agent software is a C++ application distributed as source code and is available on <a href="https://github.com/aws/aws-iot-fleetwise-edge/blob/main/README.md&quot;&gt;GitHub&lt;/a&gt; to collect, decode, normalize, cache, and ingest vehicle data to AWS. It supports multiple deployment options, such as vehicle gateways, infotainment systems, telematics control units (TCUs), or aftermarket devices. When vehicles are connected to the cloud, the Edge Agent continually receives data collection schemes and collects, decodes, normalizes and ingests the transformed vehicle data to AWS.</p><p><img class="aligncenter size-full wp-image-63414 c5" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2022/09/22/2022-iot-fleetwise-1-register.jpg&quot; alt="" width="2518" height="934" /></p><p>Let’s see the benefits and features of AWS IoT FleetWise:</p><p><strong>Signal catalog</strong>A signal catalog contains a collection of vehicle signals. Signals are fundamental structures that you define to contain vehicle data and its metadata. A signal can be a sensor and its status, an attribute as static information of the manufacturer, a branch to represent a nested structure such as <code>Vehicle.Powertrain.combustionEngine</code> expression, or an actuator such as the state of a vehicle device. For example, you can create a sensor to receive in-vehicle temperature values and store its metadata, including a sensor name, a data type, and a unit.</p><p><img class="aligncenter size-full wp-image-63420 c5" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2022/09/22/2022-iot-fleetwise-2-signal-catalog.jpg&quot; alt="" width="2292" height="1254" /></p><p>Signals in a signal catalog can be used to model vehicles that use different protocols and data formats. For example, there are two cars made by different automakers: one uses the Controller Area Network (CAN) to transmit the in-vehicle temperature data and the other uses On-board Diagnostic (OBD) protocol.</p><p>You can define a sensor in the signal catalog to receive in-vehicle temperature values. This sensor can be used to represent the thermocouples in both cars, irrespective of how this temperature data is available within the vehicle networks. For more information, see <a href="https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/signal-catalogs.html&quot;&gt;Create and manage signal catalogs</a> in the AWS documentation.</p><p><strong>Vehicle models</strong>Vehicle models are virtual declarative representations that standardize the format of your vehicles and define relationships between signals in the vehicles. Vehicle models enforce consistent information across multiple vehicles of the same type so that you can quickly configure and create a vehicle fleet. In each vehicle model, you can add signals, including attributes, branches (signal hierarchies), sensors, and actuators.</p><p>You can define condition-based schemes to control what data to collect, such as data in-vehicle temperature values that are greater than 40 degrees. You can also define time-based schemes to control how often to collect data. For more information, see <a href="https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/create-vehicle-model.html&quot;&gt;Create and manage vehicle models</a> in the AWS documentation.</p><p><img class="aligncenter size-full wp-image-63419 c5" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2022/09/22/2022-iot-fleetwise-3-vehicle-model.jpg&quot; alt="" width="2290" height="1757" /></p><p>When a decoder manifest is associated with a vehicle model, you can create a vehicle. Each vehicle corresponds to an AWS IoT thing. You can use an existing AWS IoT thing to create a vehicle or set AWS IoT FleetWise to automatically create an AWS IoT thing for your vehicle. For more information, see <a href="https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/provision-vehicles.html&quot;&gt;Provision vehicles</a> in the AWS documentation. After you create vehicles, you can create campaigns for them.</p><p><strong>Campaigns</strong>A campaign gives the AWS IoT FleetWise Edge Agent instructions on how to select, collect, and transfer data to the cloud. You can make a campaign with vehicle attributes that you added when creating vehicles, and a data collection scheme. You can manually define the data collection scheme either condition-based <a href="https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-expressions.html&quot;&gt;logical expressions</a> such as <code>$variable.myVehicle.InVehicleTemperature &gt; 40.0</code>, or time-based data collection in milliseconds such as from 10000 – 60000 milliseconds. To learn more, see <a href="https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/create-campaign.html&quot;&gt;Create a campaign</a> in the AWS documentation.</p><p>After you create and approve the campaign, AWS IoT FleetWise automatically deploys the campaign to the listed vehicles. The AWS IoT FleetWise Edge Agent software doesn’t start collecting data until a running campaign is deployed to the vehicle. If you want to pause collecting data from vehicles connected to the campaign, on the Campaign summary page, choose <strong>Suspend</strong>. To resume collecting data from vehicles connected to the campaign, choose <strong>Resume</strong>.</p><p><img class="aligncenter size-full wp-image-63418 c5" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2022/09/22/2022-iot-fleetwise-4-campaigns.jpg&quot; alt="" width="2351" height="2008" /></p><p><strong class="c4">Demo – Visualizing Vehicle Data</strong>Here is a <a href="https://github.com/aws4embeddedlinux/demo-auto-aws-iotfleetwise&quot;&gt;demo&lt;/a&gt; that aims to show how AWS IoT FleetWise can make it easy to collect vehicle data and use it to build visualizing applications.
