IoT in the automotive industry: 8 use cases

Here is how various automotive industry players, from original equipment manufacturers (OEMs) and car manufacturers to shipping companies and regular drivers, make use of IoT technology.

Connected vehicles

Automotive IoT is an essential part of connected car technology enabling vehicles to interact with external objects and road users like other vehicles, people, or road infrastructure, and ensure greater road safety and traffic efficiency. There are several communication pattern types in connected cars:

Vehicle-to-Vehicle (V2V) connection

ensures real-time data exchange between cars on the road. Vehicles share information about their location and speed, which helps regular drivers prevent accidents and emergency vehicles move freer in traffic jams.

Vehicle-to-Pedestrian (V2P) connection

implies the communication between a vehicle and pedestrians or cyclists nearby to prevent collisions on the road.

Vehicle-to-Infrastructure (V2I) communication

enables data exchange between vehicles and roadway infrastructure elements, such as cameras, overhead RFID readers, traffic lights, road signs, streetlights, and parking meters, using vehicle-to-network (V2N) cellular connection. The data received from the vehicles can be used to set speed limits or adjust traffic signal timing for better road efficiency. And vice versa, infrastructure data can provide drivers with information on road conditions, accidents, traffic jams, and available parking lots nearby.

Vehicle-to-Everything (V2E) communication

allows cars to communicate with everything that can affect the vehicle while driving, i.e., the driver, pedestrians, road infrastructure, and cellular network. In other words, V2E connection encompasses all types of connected cars’ communication patterns: V2I (vehicle-to-infrastructure), V2N (vehicle-to-network), V2V (vehicle-to-vehicle), and V2P (vehicle-to-pedestrian).

Autonomous driving

Autonomous vehicle technology, which enables cars to travel without human intervention, also relies greatly on IoT. Autonomous vehicles are powered by main and advanced driver assistance systems and active safety mechanisms. Active safety refers to AI-enabled car systems that can prevent road accidents with the help of emergency braking, driver distraction prevention, and alcohol interlock devices.

The US is currently developing guidelines for the obligatory implementation of active safety measures in new vehicles, while Europe introduced mandatory active safety measures in 2022. The Society of Automotive Engineers (SAE) developed five levels of car automation:

Level 1
Level 1

involves moderate automation with the help of driver assistance systems. A driver is in charge of steering, accelerating, and braking, while the driver assistant helps with lane centering or cruise control.

Level 2
Level 2

implies a greater level of automation due to the introduction of an advanced driver-assistance system (ADAS) for adaptive cruise control and lane centering. Should the driver get distracted, the car won’t slide off the road because the system can assist with steering and accelerating or braking. Most automated cars today are currently labeled with 1 level or 2 level of automation.

Level 3
Level 3

is the level where car automation begins to replace human driving, and self-driving is possible under certain conditions, like slow driving in traffic jams. Under other non-specified conditions, the driver must control the steering.

Level 4
Level 4

refers to a high level of car automation with a long list of conditions when self-driving is possible, including driverless taxis. Still, human intervention is required in unusual situations.

Level 5
Level 5

implies complete driving automation with no human intervention necessary. This level is also closely related to the notion of active safety.

Predictive maintenance

Integration of IoT sensors into various vehicle parts can simplify fleet and personal car maintenance. These sensors can collect data on a car's condition, fuel consumption, engine temperature, and other factors and transmit it to a cloud analytics center for further analysis. Employing predictive analytics techniques, the system can forecast when vehicle parts require upgrade, maintenance, or replacement or detect pre-failure conditions and then notify car users or fleet managers.

Fleet management

IoT sensors integrated into vehicles facilitate effective and smart fleet management by gathering real-time data on the vehicle’s performance, fuel consumption, tire pressure, oil levels, and mileage into a single storage for fleet managers’ easy access. Connecting the car to the internet and GPS, IoT allows a fleet manager to track the location of all vehicles and automatically create the most optimal routes. In addition, IoT sensors can analyze the cargo’s weight and temperature in case of perishable food or medicine transportation.

In-car entertainment

Today, in-car entertainment or in-vehicle infotainment systems are no longer limited to a radio receiver and CD player. Modern IoT systems can entertain drivers and passengers throughout the trip with music, video streaming, navigation, Wi-Fi connection, a voice assistant, and hands-free calls. Also, in-car entertainment screens can have widgets to adjust the indoor temperature or interact with the digital car interior to accommodate the seat position or the wheel.

Usage-based insurance (UBI)

Insurance companies can use the IoT technology incorporated into vehicles to provide usage-based insurance. The IoT sensors track the driving speed, acceleration rate, braking pattern, and phone usage during driving. Based on the person’s driving pattern, insurance companies issue personalized insurance premiums, so the more careless the driver, the higher the insurance fee.

Optimized car manufacturing

IoT data analytics solutions embedded into automotive production sites help increase manufacturing efficiency, save costs, and create more high-quality vehicles. Car manufacturers can leverage IoT solutions to track the supply chain of raw materials and individual car components, supervise the manufacturing equipment's condition, and take preventive measures to avoid breakdowns. By gathering gigabytes of real-time data, automakers can detect and optimize plant energy consumption, oversee the production line in real-time, and better control the cars’ quality at every production stage.

Over-the-air software updates

IoT connectivity allows for wireless over-the-air updates of the car’s infotainment and navigation systems. Car manufacturers regularly upload software updates to the cloud, so car owners can download them using Wi-Fi or cellular connection.

Motion planning

The motion planning module creates a safe and efficient path for the vehicle and decides on correct actions and paths by decomposing this task into three abstraction layers. The mission planner is responsible for the trip’s long-term planning from the car’s current location to the destination and uses the detailed road map of the environment. The behavior planner is responsible for deciding on actions and maneuvers to execute to reach the destination, for example, how long to remain in the current lane or when to change lanes. Considering the data from the behavior planner, dynamic objects around, and the occupancy grid, the local planner creates a smooth and safe movement trajectory.
