A vehicle control apparatus is mounted on a vehicle including an emergency stop function to detect an abnormal state of a driver and automatically stop the vehicle. The vehicle control apparatus provides control at a time of stopping the vehicle and includes process execution sections and a process stop section. The process execution sections perform predetermined emergency processes in response to the emergency stop function stopping the vehicle; the emergency processes control instruments mounted on the vehicle and use a battery of the vehicle as a driving power source. The process stop section stepwise stops at least part of the emergency processes performed by the process execution sections based on a predetermined stop sequence.

A method for deriving a fatigue score (100) indicative of a current drowsiness state of an operator (1) measures a plurality of signals (10, 20, 30, 40, 50, 60, 70, 80, 90) and derives a personalized fatigue score (100) for the operator using these signals (10, 20, 30, 40, 50, 60, 70, 80, 90) in a weighted and operator-personalized way.

Provided is a wearable device including a main body that is configured to be worn on a specific portion of a user's body, a sensing unit, provided in the main body, that senses a biological signal of a user, a storage unit that collects log information relating to the biological signal, and in which an index pattern relating to a state of the user included in the collected log information is stored, and a controller that sets a reference driving index, using the stored index pattern, in which when it is sensed that the user gets in a vehicle, the controller determines a current driving index corresponding to the biological signal that is sensed before and after the user gets in the vehicle, based on the reference driving index being set, and outputs feedback that notifies the state of the user that corresponds to a result of the determination.

A device for emitting radiation includes a reflector component and a clip. The reflector component has a top side, a bottom side, and a perimeter side. At least one aperture formed within the reflector component that extends from a top opening on the top side of the reflector component through to a bottom opening on the bottom side of the reflector component. The clip may be connected to the reflector component and has a flat side that is in contact with the bottom side of the reflector component. Portions of the substantially flat side of the clip are configured to be soldered to a circuit board having an emitter which extends at least partially through the aperture when the clip is soldered to the circuit board.

A system is disclosed to control operation of a vehicle based on a blood alcohol content of a driver. A detector includes a sensor configured to measure an alcohol content of air in a predetermined three-dimensional zone within a vehicle. The three-dimensional zone is proximal to a driver seat side of the vehicle. The sensor is configured to measure the alcohol content of the air independent of interaction of a driver with the detector. The sensor is configured to produce an electrical signal representative of a blood alcohol content of the driver. A controller is electrically coupled to the detector. The controller is configured to determine a tamper event. Optionally, the controller is configured to detect a presence of the driver within the vehicle. A method for preventing operation of a vehicle by an intoxicated person also is disclosed.

Provided is a vehicle stop support system for supporting vehicle stop in an emergency condition. The vehicle stop support system detects a physical abnormality of a driver; sets a target time period based on the detected abnormality; detects a plurality of stop point candidates in a traveling direction of a vehicle; estimates a time period required to reach each of the candidates; a estimates a rear-end collision risk which is a risk that, when assuming that the vehicle stops at each of the candidates, the vehicle will be rear-ended by a following vehicle; and a sets a stop point, wherein the system is operable to set, as the stop point, one of the candidates which satisfies a condition that the required time period estimated with respect thereto is equal to or less than the target time period and which is lowest in terms of the rear-end collision risk.

A vehicle control device has a processor that is configured to determine the level of active operation by the driver, to determine the relationship between the speed of the vehicle and a predetermined reference speed, and to generate a first driving plan whereby a first deceleration is used to decelerate the vehicle without activating the brake light, when it has been determined that the level of active operation by the driver is lower than the predetermined reference level and the speed of the vehicle is faster than the reference speed, and to generate a second driving plan whereby a second deceleration that is greater than the first deceleration is used to decelerate the vehicle when it has been determined that the level of active operation by the driver is lower than the predetermined reference level and the speed of the vehicle is equal to or below the reference speed.

The present disclosure provides a vehicle control device, a vehicle control method and a head-up display apparatus. The vehicle control device includes: an extraction circuit used to extract brain wave signals of a user; and a control circuit used to determine whether the user is in an unsafe driving state according to the brain wave signals, and perform at least one of operations including issuing a warning reminder and controlling vehicle deceleration when determining that the user is in the unsafe driving state.
