TheDriver Monitoring System (DMS), also known asdriver attention monitor, is a vehicle safety system to assess the driver's alertness and warn the driver if needed and eventually apply the brakes. It was first introduced byToyota in 2006 for its andLexus' latest models. It was first offered in Japan on theGS 450h. The system's functions co-operate with thepre-collision system (PCS).[1] The system uses infrared sensors to monitor driver attentiveness. Specifically, the driver monitoring system includes aCCDcamera placed on the steering column which tracks the face,[2] viainfraredLED detectors.[3] If the driver is not paying attention to the road ahead and a dangerous situation is detected, the system will warn the driver by flashing lights, warning sounds. If no action is taken, the vehicle will apply the brakes (a warning alarm will sound followed by a brief automatic application of the braking system). This system is said to be the first of its kind.[2]
In 2008, theToyota Crown system went further and can detect if the driver is becoming sleepy by monitoring the eyelids.[4][5]
In 2017, Cadillac released theirSuper Cruise system. Which allowed hands free driving at highway speeds on specially mapped highways. In order to ensure that the driver continued to pay attention to the road, they includedSeeing Machines DMS, this was initially only available in the CT6.[6]
In 2019, BMW introduced anExtended Traffic Jam Assistant System[7] in almost its entire range of car models. This allows driving at up to 37 mph.
Lexus models that have adopted the Driver Monitoring System to date, listed bymodel year:
Toyota models that have adopted the Driver Monitoring System:
General Motors first demonstrated theirSuper Cruise hands free driving usingSeeing Machines Driver Monitoring System in theCadillac CT6, soon to be rolled out across 22 models.[8]
BMW models have adopted driver monitoring system in 2019 in the optional "BMW Live Cockpit Professional" available in:
The infrared cameras are in the top middle part of the instrument cluster, part ofiDrive BMW Live Cockpit and driven by BMW Operating System 7.0.
Ford use theSeeing Machines DMS[citation needed] with infrared LEDs in a module located on the steering column behind the steering wheel as part of their active drive assist hands free driving "BlueCruise" in the 2021 Ford Mustang Mach-E and the 2021 F-150.[10][11]
Mercedes-Benz have integrated the camera from theirSeeing Machines[citation needed] driver monitoring system with the 3D instrument display,head-up display, lighting and car controls in the 2021Mercedes-Benz S-Class (W223) model.[12]
In European Union, regulation (EU) 2019/2144 regulates the driver monitoring system.[13]
driver drowsiness and attention warning means a system that assesses the driver’s alertness through vehicle systems analysis and warns the driver if needed
— regulation (EU) 2019/2144
Driver drowsiness and attention warning and advanced driver distraction warning systems shall be designed in such a way that those systems do not continuously record nor retain any data other than what is necessary in relation to the purposes for which they were collected or otherwise processed within the closed-loop system. Furthermore, those data shall not be accessible or made available tothird parties at any time and shall be immediately deleted after processing. Those systems shall also be designed to avoid overlap and shall not prompt the driver separately and concurrently or in a confusing manner where one action triggers both systems.
