In one embodiment, a method (110) that determines conditions including that a user is located in a monitored area and not wearing a wearable device (112), and provides an alert based on the determinations and an input pattern from one or plural sensors (114).

A warning system having a plurality of components including a Lidar device, an adjustment means, an audio source, a light source, a controller, and a power source. The warning system produces at least one of the audible sound and the light signal when the one or more laser beams detects a foreign object. A method for providing a warning in the event a foreign object is detected.

A system for preventing sleep in vehicle operators can include a user device and a mat operatively connected to the user device and positioned on a driver-side floor of a vehicle. The mat can be configured to, via one or more processors, receive an enablement signal from the user device; and in response to receiving the enablement signal, cause a haptic effects generator to generate vibrations within the mat.

A vehicular interior rearview mirror assembly includes a mirror head adjustably attached at a mounting base configured to attach at an interior portion of a vehicle. A driver monitoring camera is accommodated by the mirror head so as to move in tandem with the mirror head when the mirror head is adjusted relative to the mounting base to adjust a driver's rearward view. A forward viewing camera is accommodated by the mounting base so as to have a forward field of view through the vehicle windshield. A processor is operable to process image data captured by the driver monitoring camera to determine (i) driver attentiveness, (ii) driver drowsiness and/or (iii) driver gaze direction. The processor adjusts processing of the image data captured by the driver monitoring camera to accommodate adjustment of the mirror head when the driver adjusts the mirror head to adjust his or her rearward view.

An alertness estimation apparatus 10, includes: an image extraction unit 11 that extracts an image of a portion including eyes from an image data of a face image of a human; a first alertness estimation unit 12 that estimates a first alertness based on the extracted image; a pulse wave detection unit 13 that determines whether or not the estimated first alertness satisfies a set condition, and detect a pulse wave of the human from the face image, when the first alertness satisfies the set condition; and a second alertness estimation unit 14 that estimates a second alertness of the human based on the detected pulse wave.

A method of operating a radar sensor system that is configured to determine range and velocity information from radar waves reflected by a scene in an interior of a vehicle for vital sign detection. The method includes steps to decompose reflected and received signals into range and velocity information, to measure the movement over time in specified range gates and to evaluate the similarities between them. Based on the characteristics of similar behaving range bins, it can be decided whether any detected movement is related to an internal or external disturbance or by vital signs.

A driving support apparatus according the embodiment includes: a determination unit that determines driving support control having a driving support resource amount that is capable of assuring required resources with respect to a resource amount that is capable of being assured by a level of a vehicle driver's concentration on driving, the required resources being assumed to be required for safe driving; and a driving support unit that changes the driving support control to be performed to driving support control that is determined by the determination unit to be capable of assuring the required resources.

Driving support ECU sets a driver's state to “temporarily abnormal” and decelerates a vehicle when a driver of the vehicle has been first determined to be in an abnormal state where the driver loses an ability to drive the vehicle. Driving support ECU changes the driver's state to “regularly abnormal” in a case when the abnormal state of the driver remains unchanged when a vehicle speed decreases to a set vehicle speed, and at this point, reports to a help net center HNC. With this configuration, a report to the help net center HNC can be made at an appropriate timing.
