Abstract: The driver assistance system comprises a detector, a navigator, a stimulator, and a voice interactor. The detector detects wakefulness reduction of a driver or absent-minded driving by the driver. The navigator navigates a vehicle based on map information. The stimulator continuously or intermittently applies stimulation to the driver. The voice interactor interacts with the driver by voice. The navigator searches for a resting facility on a route from the map information in response to a detection of the wakefulness reduction or the absent-minded driving. The voice interactor executes a first interaction of proposing navigation to the resting facility by the navigator in response to the detection of the wakefulness reduction or the absent-minded driving, and executes a second interaction of proposing application of stimulation by the stimulator after an execution of the first interaction and during a period until the vehicle arrives at the resting facility.

Abstract: A drowsiness sign notification device detects an eye-closed state of a driver of a vehicle from each of face images; determines whether a first eye closure ratio of the number of face images with the eye-closed state to the number of the face images generated in a first period exceeds a first threshold; determines whether a second eye closure ratio of the number of face images with the eye-closed state to the number of the face images generated in a second period longer than the first period exceeds a second threshold less than or equal to the first threshold after determination that the first eye closure ratio does not exceed the first threshold; and notifies detection of a sign of drowsiness to the driver, when the first eye closure ratio exceeds the first threshold or that the second eye closure ratio exceeds the second threshold.

Abstract: A driving support device includes a processor configured to detect a sign of sleepiness of a driver of a vehicle, based on a driver image representing the driver's head generated by a driver monitoring camera configured to take a picture of the driver's head, determine a response request to the driver, depending on environment around the vehicle or a travel condition of the vehicle, when a sign of the driver's sleepiness is detected, and notify the driver of the response request via a user interface provided in the vehicle.

Abstract: A drowsiness sign notification system that gives a drowsiness sign notice to a driver that shows a drowsiness sign includes a driver monitor and a controller. The driver monitor detects the driver state being a state of the driver. The controller executes a drowsiness level estimation process in which a drowsiness level of the driver from a plurality of drowsiness levels based on the driver state. And, the controller executes an accumulation process in which a drowsiness point that is numerical value corresponding to the drowsiness level estimated in the drowsiness level estimation process is accumulated. Then, when an accumulation value of the drowsiness point calculated in the accumulation process exceeds a predetermined threshold, the controller determines that the driver shows the drowsiness sign.

Abstract: A drowsiness sign notification system applied to a vehicle includes a driver monitor and a controller. The driver monitor detects a driver state being a state of a driver of the vehicle. The controller executes a drowsiness sign determination process that determines whether or not the driver shows a drowsiness sign based on the driver state. When it is determined that the driver shows the drowsiness sign and an activation condition is satisfied, the controller executes rest area informing process that informs the driver of a rest area. The activation condition of the rest area informing process is set from a viewpoint of a relationship between a location of the rest area and a target route of the vehicle, or an expected time required for the vehicle to reach the rest area.

Abstract: This paper discloses a careless driving determination apparatus. The careless driving determination apparatus captures a plurality of face images of a driver of a vehicle in a predetermined period using a driver monitor camera. Then, it determines whether each of the plurality of face images shows first status in which the driver wears a wearing object or second status in which the driver does not wear the wearing object, the wearing object covering a part of a face of the driver. Then, it calculates a distribution range of angles of face directions or angles of gaze directions of the driver. Then, it sets a threshold range based on ratio of face images that show the first status and ratio of face images that show the second status. Then, it determines that the driver is in a careless driving state when the distribution range is included in the threshold range.

Abstract: A drowsiness sign notification system applied to a vehicle includes a driver monitor and a controller. The driver monitor detects a driver state being a state of a driver of the vehicle. The controller executes a drowsiness sign determination process that determines whether or not the driver shows a drowsiness sign based on the driver state. When it is determined that the driver shows the drowsiness sign, the controller executes a first drowsiness sign notification process that gives a first drowsiness sign notice to the driver through display or vibration without using audio. When it is determined again that the driver shows the drowsiness sign after the first drowsiness sign notification process, the controller executes a second drowsiness sign notification process that gives a second drowsiness sign notice to the driver through audio.
