In-Cabin Monitoring Systems (DMS, OMS, etc.) Research Report, 2026
In-Cabin Monitoring System Research: DMS to Become Mandatory in 2027, Expected to be Installed in Over 14 Million Vehicles
ResearchInChina released the In-Cabin Monitoring Systems (DMS, OMS, etc.) Research Report, 2026. Based on China’s passenger car market, the report comprehensively analyzes the installation, policy orientation, and mainstream technology application scenarios of in-cabin monitoring systems (including Driver Monitoring System (DMS) and Occupant Monitoring System (OMS)). It also combs through solutions from core global and Chinese suppliers and presents typical vehicle application cases from OEMs to clearly demonstrate industry development trends.
In 2025, Driver Monitoring System (DMS) was installed in about 5.644 million passenger cars as a standard configuration in China, a year-on-year increase of 29.2%, with the installation rate of about 24.6%, up by 5.5 percentage points on an annual basis; Occupant Monitoring System (OMS) was installed in about 1.417 million passenger cars as a standard configuration, a year-on-year increase of 60.1%, with the installation rate of about 6.2%, up by 2.3 percentage points on an annual basis.
1. Passenger Cars Enter the Era of Mandatory Standard DMS and DMS+ADAS Collaborative Decision Linkage
In April 2026, the Ministry of Industry and Information Technology of China (MIIT) completed and publicized the mandatory national standard Intelligent and Connected Vehicle - Safety Requirements of Combined Driver Assistance System (Draft for Approval). As China’s first mandatory standard for L2 combined driver assistance, it is scheduled to take effect on January 1, 2027. The core clause stipulates that: after being activated, all L2 systems must continuously monitor two types of driver behaviors - hands off steering wheel and eyes off road-realizing “hands + eyes” dual-dimensional monitoring, and cannot be disabled.
With the intensive implementation of relevant policies and regulations inside and outside China, equipping new vehicles with DMS has become mandatory. ResearchInChina predicts that DMS will be installed in over 14 million passenger cars in China in 2027.
The EU General Safety Regulation (GSR II) mandates that all new vehicles must be equipped with DMS starting from July 2026.
Euro NCAP 2026 upgrades Driver State Monitoring (DSM) to a core part (25/100 points) of the Safe Driving module. In the Crash Avoidance module, greater emphasis is placed on the reliability and user experience of driver monitoring technologies. To achieve high scores, vehicles must employ continuous eye and head tracking, and link driver state to assistance system sensitivity. For example, when DSM judges the driver is distracted/impaired, the lane assist system (Lane Keeping Assist (LKA)/Lane Departure Warning (LDW)) must remain sensitive and available; when the driver is focused and unimpaired, interventions shall be partially or fully suppressed.
Meanwhile, as vehicle safety access requirements continue to escalate, DMS is no longer limited to traditional driver state monitoring/warning. It is gradually evolving toward deep integration and collaborative decision with ADAS combined driver assistance systems, becoming a core link in the intelligent driving safety system.
Case 1: In July 2025, Mobileye announced that its DMS? is directly fused with Mobileye Advanced Driver Assistance Systems (ADAS) on a single chip to simplify the system, reduce costs, and support SoC/ECU consolidation goals.
Specifically, Mobileye DMS? fuses in-cabin monitoring with road information from ADAS cameras to assess whether the driver notices critical objects/risk areas ahead, and dynamically adjusts vehicle system response settings based on the driver’s real-time focus level.
Case 2: In April 2025, ArcSoft demonstrated the SouthLake multifunctional (ADAS + DMS) front-view all-in-one vision reference design and software solution. Its core feature is integrating exterior driver assistance, in-cabin driver state monitoring, and full-time driving recording to help automakers quickly meet regulatory requirements and achieve mass production.
2. Multiple Automakers Offer “Driver Incapacitation Assistance/Takeover” to Safeguard Driving Safety
Driver Incapacitation Assistance refers to a range of emergency responses initiated by the driver assistance system when the DMS detects sudden driver incapacitation such as fainting or cardiac arrest. The system actively takes over the vehicle to decelerate, stop, activate hazard lights, unlock doors, and call for help, avoiding accidents and gaining rescue time. This function is currently equipped in some mid-to-high-end vehicle models and is continuously optimized.
A review of models with driver incapacitation assistance shows different brands adopt distinct risk-avoidance logics. Some emerging auto brands follow a “proactive risk avoidance, complete safety” logic, integrating L2+ driver assistance and active safety to autonomously judge road conditions, activate lane changes with turn signals, and find the nearest emergency lane to pull over. Traditional joint-venture brands adopt a more cautious approach of “prioritizing control and stability”, executing the safest actions within system limits—safe stopping.
Case 1: The driver incapacitation assistance function of XPeng GX, first unveiled in April 2026, triggers the following protection sequence when the driver becomes unresponsive during intelligent driving on a highway: Step 1: Activate hazard lights and smoothly change lanes to the emergency lane; Step 2: Continuously pump the brake to rouse the driver; Step 3: Perform automated parking and SOS light projection; Step 4: Synchronously call rescue and unlock doors.
Case 2: In January 2026, ZEEKR added “Emergency Stop Assist” via OTA update. During assisted driving, if the driver keeps hands off the steering wheel for a long time, fails to respond, and still remines unresponsive after multiple audio-visual reminders, the vehicle safely stops and activates hazard lights to prevent loss of control due to sudden illness, fainting, or other incapacitation, reducing accident risks.
3. Rapid Popularization of 60GHz In-Cabin Monitoring Radar
In-cabin radar is rapidly becoming a mainstream solution for in-cabin monitoring by virtue of contactless sensing, privacy protection, and penetration through obstructions (e.g., blankets).
Current automotive in-cabin radar solutions mostly adopt 60GHz radar, applicable to child presence detection, seatbelt reminders, intrusion detection, smart airbag adaptive triggering, life presence detection, gesture recognition, and driver drowsiness detection. It also adapts to complex in-cabin environments and can be flexibly deployed in multiple key positions such as the roof, B-pillar, under rearview mirror, inside seats, or integrated into the sunroof for full-cabin coverage without blind spots.
