A vehicle access system is disclosed having the plurality of system nodes for localizing a target portable device. In addition to Passive Entry/Passive Start (PEPS) features, the vehicle access system is configured to provide a variety of additional intelligent features depending on which zone of the vehicle the target portable device is located, depending on an identity of the person carrying the target portable device, and depending on other parameters or conditions.

A drowsiness level of a driver in a vehicle is determined. A preliminary alert is performed in response to that the drowsiness level is higher than an alert threshold value. A main alert is performed to prompt the driver to wake up from drowsiness as necessary after the preliminary alert. In response to that a predetermined response operation by the driver is detected within a predetermined time after the preliminary alert, the alert threshold value is changed to be higher.

A drowsiness prediction device includes: a carbon dioxide concentration detector that detects the concentration of carbon dioxide in a compartment; an oxygen saturation detector that detects oxygen saturation in the body of a driver present in the compartment; a predictor that predicts, according to the concentration of carbon dioxide and the oxygen saturation detected, a level of drowsiness that the driver would feel after the detection of the concentration of carbon dioxide and the oxygen saturation; and an outputter that outputs information indicating the predicted level of drowsiness.

A computer in a vehicle is programmed to receive sensor data about a vehicle occupant, select a category of behavior of the occupant based on the sensor data, and navigate to a predetermined location based on the selected category. The vehicle may be an autonomous vehicle that can be operated by the computer.

A vehicle alert apparatus includes: a drowse detector that detects drowse of a driver; an inattention detector that detects inattention of the driver; a vehicle speed detector that detects the vehicle speed; a notification portion that executes alert for the driver; and an alert controller that controls the alert executed by the notification portion based on a detection result of the drowse of the driver, a detection result of the inattention of the driver, or a detection result of the vehicle speed.

A snooze alert device, system and method monitor a user and alert the user if the user starts to fall asleep while operating a vehicle.

A safety drive assist apparatus includes an imaging unit, an information acquisition unit, a first determination processor, a second determination processor, and a control processor. The imaging unit captures an image of an occupant inside a vehicle. The information acquisition unit acquires information including biometric information of the occupant inside and outside the vehicle. The first determination processor and the second determination processor determine a physical fatigue level and a mental fatigue level of the occupant inside the vehicle, respectively, on the basis of the image of the occupant inside the vehicle captured by the imaging unit or the information including the biometric information of the occupant inside and outside the vehicle acquired by the information acquisition unit. The control processor controls a vehicle device on the basis of one or both of determination information obtained by the first determination processor, and determination information obtained by the second determination processor.

A system for detecting drunken driver is presented. The system includes an alcohol detecting device, a photographing device, and a locking device. The alcohol detecting device can receive a blood alcohol content value of a driver of a vehicle detected by a sensor, and determine whether the blood alcohol content value exceeds a first predetermined value. The alcohol detecting device can send alcohol concentration exceeding information to the photographing device to record video and to the locking device to lock vehicle when the blood alcohol content value exceeds the first predetermined value.

According to one embodiment, a method, computer system, and computer program product for managing medical events affecting a driver or passenger of a vehicle is provided. The present invention may include detecting, based on sensor data, a medical event affecting a driver of the vehicle; confirming, with a secondary decision maker, the medical event and one or more environmental changes to an internal environment of the vehicle based on the detected medical event; and executing the one or more environmental changes.
