DRIVER STATE DETECTION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18415649 titled 'DRIVER STATE DETECTION DEVICE
The patent application describes a driver state detection device that uses a driver monitor camera to capture the face of a driver and analyze their facial orientation or line-of-sight direction to determine if the driver is distracted.
- The device can detect distracted driving when the driver's facial orientation is maintained outside the allowable range for a predetermined time period.
- The allowable range is set based on factors like steering wheel operation and vehicle speed, which are correlated with the driver's attention on the road.
- By monitoring the driver's facial cues, the device can help prevent accidents caused by distracted driving.
Potential Applications: - Automotive safety systems - Fleet management - Driver behavior analysis
Problems Solved: - Reducing the risk of accidents due to distracted driving - Improving road safety - Enhancing driver monitoring capabilities
Benefits: - Increased safety on the road - Early detection of distracted driving behavior - Potential reduction in accidents and injuries
Commercial Applications: Title: "Advanced Driver Monitoring System for Enhanced Safety" This technology can be utilized by automotive manufacturers, fleet management companies, and insurance providers to enhance driver safety and reduce the risk of accidents.
Questions about Driver State Detection Device: 1. How does the device determine if a driver is distracted? The device analyzes the driver's facial orientation or line-of-sight direction to detect signs of distraction.
2. What factors are used to set the allowable range for facial orientation? The allowable range is based on operating parameters related to steering wheel operation and vehicle speed.
Original Abstract Submitted
A driver state detection device provided with a driver monitor camera configured to capture the face of a driver of a vehicle to generate a facial image of the driver and a control device. The control device is configured so as to detect the facial orientation or the line-of-sight direction of the driver based on the facial image, judge that the driver is driving distracted when the facial orientation or the line-of-sight direction of the driver is maintained for greater than or equal to a predetermined time period at the outside from the allowable range allowed as the facial orientation or the line-of-sight direction of the driver, and set the allowable range based on an operating parameter which is in a correlative relationship with steering operation of the steering wheel of the vehicle and the speed of the vehicle.
