The method for sensing occupancy status within an automotive vehicle, as detailed in patent LU 92541 A1 and assigned to IEE Sarl, introduces an innovative radar sensor system. This system comprises an antenna system, at least one sensor, and processing circuitry, collectively working to provide comprehensive detection and classification of vehicle occupants.
The primary objective of this method is to illuminate at least one occupiable position within the vehicle using continuous wave (CW signals) generated by the antenna system. Notably, these CW signals are frequency modulated in time to enhance their effectiveness in occupant detection. The ensuing step involves receiving at least one sensor signal, denoted as "a," which results from the reflection of the CW signals. The at least one sensor, with defined receive channels (1...i), each operating at a different frequency (f1...fi), captures these signals for further analysis.
The processing circuitry, a pivotal component of the radar sensor system, undertakes DC offset removal for each receive channel. This process generates modified signals, denoted as "b," which serve as the basis for generating one or more occupancy status signals (34, 38). These signals convey properties related to the occupiable position, thereby facilitating in-vehicle occupant detection and classification. The applications of this technology extend to airbag suppression, passenger presence detection, monitoring vital signs of passengers, and seat-belt reminder functionality (SBR).
The radar system, as outlined in the patent, can consist of one or two (or four) outputs per channel (l/Q). The received signal undergoes mixing down, facilitated by a single-channel demodulator or an l/Q demodulator, transitioning it into the baseband for further analysis. An advanced signal processing approach, inclusive of an auto calibration routine and clutter removal, enhances the system's capability to detect occupants, monitor vital signs (such as breathing and heart rate), and determine their distance from the radar system.
this patented radar sensing method, developed by IEE Sarl, introduces a cutting-edge system for sensing occupancy status within an automotive vehicle. By utilizing continuous wave signals and advanced signal processing techniques, this method goes beyond simple detection to classify occupants, monitor vital signs, and enhance overall safety features within the vehicle. The incorporation of accelerometer data further enriches the system's capabilities by providing information about the vehicle's vibrations or motions, contributing to a more robust and sophisticated occupant sensing technology. The patent, dated March 11, 2016, signifies a significant advancement in radar-based occupant detection systems within the automotive industry.

Segment Outlook | Vehicle Type and Channel |
The Automotive Occupant Sensing System Market is projected to grow from USD 2.5 Billion in 2021 to USD 4.5 Billion by 2032, exhibiting a compound annual growth rate (CAGR) 6.2% during the forecast period (2023 - 2032).
Automotive Occupant Sensing System has been witnessing steady growth over a period of time. Automotive occupant sensing systems basically detects the presence of individuals in the vehicle, based on which the amount of deflation or inflation is required by airbags in case of an accident. Increasing demand for safety features in automobiles, stringent government norms and rapidly rising safety awareness among individuals are some of the factors primarily driving the automotive occupant sensing system market. With the New Car Assessments Program awarding safety ratings based on vehicles safety performance, automotive manufacturers have been increasingly integrating automotive occupant sensing system in vehicles. Earlier available only in premium vehicles, automobile manufacturers have started integrating these features in entry level vehicles as well to broaden their customer base thus propelling the demand in the automotive occupant sensing system market.
The market for Automotive Occupant Sensing System systems is expected to grow with an increase in demand for automobile, majorly in the United States. There is an immense demand of commercial vehicles in United States. With the increase in demand of commercial vehicles there is an increase in demand for Automotive Occupant Sensing System market. The growth of the North America region is also driven by the presence of major automotive system manufacturers which are mainly focusing on key developments such as expansion, mergers & acquisition, product launch and others. Moreover, the spending of much of the time in Vehicles by the people generates the need for adoption of advanced technologies, such as Automotive Occupant Sensing System systems. Owing to all these factors, the growth of the region is expected to grow at a rapid pace.
Due to the presence of most populous countries of the world such as China and India among others, the dominance of APAC becomes evident in the global Automotive Occupant Sensing System systems market value. The market has been experiencing rapid growth in the last two years owing to the rising sales of passenger cars, emerging economies, shifting of global players and technological advancements are giving a much needed thrust to the Automotive Occupant Sensing System systems market. Another major reason behind APAC leading the global market is that the countries within this region were able to sustain its economy during the global economic crisis of 2008-09 and have been able to showcase continued growth in automobile production and sales across the globe. Although, of late, there has been a significant influx of technology in the Asia-Pacific region, the lack of major market players and underdeveloped automotive infrastructure has resulted in alienating certain geographies, particularly the African and Middle East region.
