1. Climate Concierge: AI-Optimized HVAC and Comfort Systems

One of the most promising applications of in-vehicle AI is personalized climate control. While cars have had automatic temperature settings for years, AI is enabling a far more granular level of optimization by leveraging multiple data points and deep learning.

AI-powered HVAC systems use an array of sensors (thermal imaging, humidity, air quality, etc.) and cameras to continually monitor cabin conditions and occupants. Computer vision detects who is in the vehicle and where they are sitting. Facial recognition assesses temperature sensitivity based on factors like age, weight, and clothing.

The AI ingests this multi-modal sensor data and runs it through deep learning models that predict optimal comfort settings for each passenger in real-time. It can direct airflow, heating, and cooling to specific zones, and even adjust humidity, cabin filtration, and air fragrance.

Over time, the AI learns each passenger‘s HVAC preferences in different contexts (e.g. after exercise vs. after a meal) and builds a robust personalized profile that is automatically applied whenever that person enters the vehicle.

For example, Mercedes-Benz‘s AI-powered ENERGIZING COACH system creates a "wellness experience" by optimizing climate, seat kinetics, lighting, and music based on data from smartwatch stress sensors. It recently partnered with AIR AROMA to integrate scent into the system, with fragrance blends that promote specific cognitive states like alertness or relaxation.

Personalized, context-aware climate control is quickly becoming a key differentiator for luxury auto brands. In 2023, Jaguar Land Rover, Lexus, Byton, and Hyundai all introduced vehicles with AI-powered multi-zone climate systems that use biometrics and machine learning personalization.

The size of the global automotive HVAC market is expected to reach $25.1 billion by 2026, up from $16.9 billion in 2021. Much of this growth will be driven by AI-enabled climate systems that improve passenger comfort and energy efficiency.

2. Guardian Angel: Intelligent Driver Monitoring for Safety

Another area where AI is having a significant impact on vehicle comfort is driver monitoring systems (DMS). Using inward-facing cameras and computer vision, AI-powered DMS continuously analyze the driver‘s physical and cognitive state to identify potential safety risks.

Eye tracking algorithms gauge drowsiness and distraction by monitoring percentage of eye closure, blink rate and duration, and gaze direction. Facial expression analysis detects yawning, head nodding, and other signs of fatigue. The AI synthesizes these metrics to assess driver alertness in real-time.

If the system determines the driver is drowsy or not paying attention, it can provide progressive alerts – from a coffee cup icon to audible chimes to vibrating the steering wheel or seat. In more advanced systems, the AI can even initiate vehicle actions like turning up the AC, tightening the seatbelt or slowing to a stop if the driver is unresponsive.

AI-powered driver monitoring is quickly becoming a key safety feature, with the European Union mandating DMS in all new vehicles from 2024. Major suppliers like Bosch, Valeo, and Seeing Machines are developing turnkey DMS solutions that can be integrated into any vehicle.

General Motors‘ Super Cruise hands-free driving system uses a Seeing Machines DMS that combines eye gaze tracking with head pose detection. If the driver looks away from the road for more than a few seconds, Super Cruise issues an escalating series of visual, audible and haptic alerts to demand attention.

Subaru‘s DriverFocus DMS uses facial recognition and eye tracking to identify signs of driver distraction or drowsiness. It keeps a personalized profile of each driver‘s "normal" attention levels and provides customized alerts when they deviate from their baseline.

By 2026, 73% of all new vehicles are expected to have AI-powered driver monitoring systems, according to ABI Research. With fatigue and distraction contributing to over 10% of all crashes, DMS will play a vital role in improving road safety and occupant comfort.

It can provide detailed status info on range, tire pressure, and other vehicle vitals, and can even roll the windows up or down in response to "I‘m cold" or "I‘m hot."

• NIO‘s NOMI uses computer vision and voice recognition to interact with drivers, handling tasks like taking selfies, selecting music based on mood, and even telling jokes. The NOMI "Hitch" dating service connects single NIO drivers with each other based on route compatibility and mutual interest.

The automotive voice and speech recognition market is projected to reach $4.1 billion by 2027, according to Meticulous Research. As natural language AI becomes more sophisticated, in-vehicle voice assistants will become an increasingly powerful and popular interface for the mobility experience.

4. Mobility Identity: Biometric Vehicle Access and Personalization

As vehicles collect more personal data on users to enable comfort and convenience features, security and privacy are paramount. Biometric technology, powered by AI, offers a robust solution for authenticating drivers and passengers.

Major automakers are replacing physical car keys with biometric access systems that use fingerprint, facial, voice, or even heartbeat recognition. Machine learning models are trained on an authorized user‘s unique biometric signature, which is securely stored in an encrypted database either on the edge or in the cloud.

When someone attempts to enter and start the vehicle, the biometric system uses computer vision and deep learning algorithms to compare their biometric data in real-time to the authorized user profiles. If there is a match, the vehicle unlocks and applies that user‘s personalized comfort and infotainment settings.

Examples of vehicles offering biometric access and personalization in 2023 include:

• The Hyundai Sonata uses a fingerprint sensor on the door handle and ignition button to unlock the vehicle and load driver-specific settings for seating position, mirrors, lighting and temperature.

• The Byton M-Byte SUV scans the driver‘s face when they sit down, then automatically adjusts the seat, mirrors, and climate to their preferences. It also uses facial recognition to bring up personalized calendars and playlists on the 48-inch dashboard display.

• The Rivian R1S and R1T use RFID scanners in the B-pillar to detect a person‘s unique key fob or smartphone "identity," then apply their favorite cabin presets as they approach the vehicle.

The automotive biometrics market is expected to reach $1.13 billion by 2024, up from $183 million in 2016. Beyond vehicle access, biometrics will be used for continuous authentication to enable safety features like driver monitoring and risk-adjusted insurance pricing.
