IDTechEx covers the ever-growing, multifaceted autonomous vehicle market, made possible with advancing automotive radar and sensing technology. Their portfolio of Robotics & Autonomy Research Reports is home to extensive research into the sector, covering ADAS, radar, and in-cabin sensing, and providing market forecasts spanning the next decade.
ADAS and radar developments
Automotive radar technology is allowing for increasingly advanced autonomy in vehicles due to the increased safety possibilities. Front and side radars both serve unique purposes, allowing for ADAS and autonomous features to be enabled, such as self-driving capabilities as a result of the vehicle's increased awareness of surrounding areas. The latest version of IDTechEx's "Passenger Car ADAS Market 2025-2045: Technology, Market Analysis, and Forecasts" report provides the latest developments within the market.
Long range and angular resolution are important for the vehicle's front radars to make sure that people or vehicles can be detected out in front of the car as early as possible. This object detection feature, part of the adaptive cruise control system, is imperative to ensure the correct action can be taken and that the driver can be notified of potential danger early enough. Automatic emergency braking is one of the most notable features made possible with front radars, so the car can respond exceptionally fast, and react quicker than a human may be able to.
Side radars specifically are used for blind spot detection and subsequently lane change assist, to help detect potentially advancing vehicles before switching lanes. Reversing out of a parking space can also engage the side radars, as they can be used for cross-traffic detection to seek out potential danger where the driver is unable to see. These radars, increasingly seamless in their design, require a wider field of view than front radars, to ensure the car's surrounding areas can be monitored at all times.
Combining front and side radars for maximum protection
Pedestrian automatic emergency braking is a feature which makes use of both front and side radars, demonstrating an application where the two can work together for an additional level of safety such as at junctions. IDTechEx's report, "Automotive Radar Market 2025-2045: Robotaxis & Autonomous Cars" explores the technologies behind radar systems, and how they are becoming increasingly implemented into vehicles in line with growing safety regulations. IDTechEx forecasts that by 2030, more than 90% of new passenger vehicles in Europe will be equipped with at least three radar units, while premium OEMs are already deploying 5-7 radars per vehicle. This expansion is expected to push the global automotive radar market to over US$16.3 billion by 2034.
The use of radar can extend to the development of real-time maps that update in line with information received from other vehicles on the road concerning traffic or holdups. In the future, such technologies could extend to controlling traffic light systems and optimizing traffic control in busy areas, which could play a role in reducing accidents and avoidable congestion. IDTechEx's report, "Autonomous Vehicles Market 2025-2045: Robotaxis, Autonomous Cars, Sensors", explores a number of possibilities.
Seamless integration with other ADAS sensors
Radar alone is not sufficient for high levels of protection on the road; integration with cameras and LiDAR ensures redundancy and robustness. Cameras provide classification, including reading traffic signs or recognizing cyclists, while radars excel in range and velocity detection under adverse weather. Increasingly, sensor fusion architectures bring these data streams together in central compute platforms. The concept of a "radar mesh" or "protective radar dome" reflects this trend, enabling 360° situational awareness.
Personalized driving with sensing and natural language AI
With advancing autonomous software and the implementation of AI, passengers can take full advantage of the possibilities to have more engaging and personalized journeys. AI-driven in-cabin systems are becoming an equally important enabler of safe and engaging mobility. Driver monitoring systems (DMS), already mandated in Europe from 2024, use infrared cameras and sensor fusion to detect fatigue or distraction.
In-cabin sensing features could work alongside AI, and prompt it to make decisions to suggest placing a coffee order or to stop at the next services for a driving break. Detecting fatigue or drowsiness within the driver is just one example of the possibilities of in-cabin sensing, explored in depth within IDTechEx's report, "In-Cabin Sensing 2025-2035: Technologies, Opportunities, and Markets". IDTechEx's research projects the in-cabin sensing market to exceed US$6 billion by 2035, fuelled by both regulatory mandates and the push for enhanced user experience.
AI assistants are becoming increasingly popular too, so drivers can ask the car about the news or the weather or ask to be admitted into a work meeting whilst on the move. This functionality can also be delivered in the form of a talking cartoon with the enhancement of visual interfaces, to give the car's software features a more engaging and personal feel. IDTechEx's report, "Autonomous Driving Software and AI in Automotive 2026-2046: Technologies, Markets, Players", explores the natural language capabilities of AI within vehicles that allow this experience to be as seamless, humanlike, and enjoyable as possible.
