Automotive IoT Connectivity trends are transforming the relationship between OEMs and the users of automobiles. As the IoT revolution takes over the automotive industry, vehicles are turning into a hub of IoT devices generating and sharing vast volumes of data about the vehicle’s performance, surroundings, connected third-party systems, driver behavior, auto service providers, and a lot more besides.

To fulfill the ever-increasing demand for connected automotive services that are supported by IoT sensors, OEMs are focusing on designing innovative software and service modules for the vehicle. Hi-tech connectivity solutions are critical for meeting the growing demand for more sophisticated vehicular services like connected car solutions, advanced driver-assistance systems (ADAS), in-vehicle infotainment systems, and navigation & telematics solutions.

Let’s take a close look at the trending automotive IoT connectivity solutions that are facilitating safe, efficient, and comfortable driving.

1) Over-the-air software updates

Over-the-air (OTA) software updates are cloud-enabled services which allow automotive companies to improve vehicular functions through remote software updates. Automotive IoT-based OTA update services allow vehicular systems to download newly released files related to software updates for infotainment, telematics, software that control vehicle’s parts, electronic control units, and more.

OTA updates directly update the software on the vehicle’s systems, or can be used to update external devices such as mobile applications configured with the vehicle. As OTA software updates can be done remotely, it reduces unnecessary visits to the service station. It also allows automotive companies to fix the issues related to updates instantly and upgrade any functionality without any hassle.

An over-the-air software update can be broken down into three stages:

Designing the “update package”: Designing of the software update package begins with the identification of the bugs in the existing vehicular systems or assessing the requirement of integrating a completely new feature in the system. Then, a software or firmware build is designed and prepared with required security and configuration settings, intended for targeted in-vehicle devices and applications.

Update delivery management: Post designing, the OTA update package is forwarded to the distribution platform managed by automotive OEMs and vendors. The distribution platform takes care of the software versioning and delivers the right software package to the projected vehicular systems.

OTA update execution: At this stage of the OTA updates, the encrypted software packages are received by the vehicular systems (Telematics control unit) and then downloaded from the server via a secured transport channel. In order to initiate the software update, a user needs to trigger the updation process of the received files.

Over-the-air (OTA) software updates for automotive IoT solutions makes changes to the following areas of vehicle functionalities:

Cloud security and third-party cloud applications: OTA provides timely upgrades to cloud security platforms for vehicles to establish a secure connection with other vehicles, infrastructure, and network. It also facilitates updation of third-party application over the cloud like apps for navigation and high definition maps.

Predictive diagnostics solutions based on automotive IoT are designed to notify the driver of any future breakdown or failure of some of the vehicular systems in advance. Predictive maintenance systems continuously monitor, collect, record, transfer, analyze and evaluate data from in-vehicle sensors – in sync with various vehicular parts – to keep track of the vehicle’s functional metrics. The vehicle’s sensors gather data like engine temperature, speed, acceleration, tire pressure, fuel level, engine-oil, brake fluid level, emissions, and other aspects and evaluate them against their ideal limit for the type of vehicle, and notifies the drivers or operators instantly in case of any discrepancy.

How does Predictive Maintenance for Automotive sector work?

Below are some of the benefits of predictive maintenance systems:

Real-time alerts: Predictive maintenance systems powered by automotive IoT solutions are capable of identifying the problem in critical components of the vehicle and send real-time notification if any part needs to be repaired or replaced.

3) Vehicle to Everything (V2X) Connectivity

RELATED BLOG FAQs on Automotive IoT

Vehicle to Everything (V2X) is emerging as a key driver in connected vehicle technology, owing to its ability to enhance safety, mobility, and efficiency of transportation systems. It is an intelligent communication system driven by automotive IoT sensors, frameworks and gateways which is used to ensure interconnectivity between vehicles, infrastructure, networks, and pedestrians.

When a V2X module, a vehicle’s onboard sensors exchange information with sensors in the surrounding areas over high bandwidth, low -latency and highly reliable links. V2X allows vehicles to look beyond the driver’s range and generate alerts regarding road safety, traffic flow, and obstacles in real time. Some of the components of V2X are as follows:

Vehicle-to-vehicle (V2V) communication: Vehicle-to-vehicle is an advanced communication system which allows vehicles to communicate with the nearby vehicles in transit. V2V communication works on 5.9 GHz dedicated short-range communications (DSRC). DSRC is a high speed, secure and short-to-medium range communication channel, which establishes a connection with the approaching vehicles instantly and notifies drivers of relative speed, acceleration, direction, and distance.
