A driver assistance method and a driver assistance apparatus are provided, which may be applied to the field of autonomous driving or intelligent driving. The driver assistance method includes: determining that a driver is in an abnormal state; determining that a first operation performed by the driver on a first terminal is an abnormal operation; and performing first processing, where the first processing includes outputting indication information and/or control information, and the indication information or the control information indicates a second operation performed on the first terminal, or the first processing includes controlling the first terminal to perform the second operation.

According to the present disclosure, a drunk driving prevention system including: an alcohol detection unit configured to detect a driver's inebriation through the breath test device provided in a vehicle; a computation unit configured, when the driver is detected to be in a drunk state by the alcohol detection unit, to compute a driving-possible time at which the drunk state is resolved in the future so that driving is possible; and a notification unit configured to output the driving-possible time or whether or not driving is possible through an infotainment system of the vehicle or a driver's terminal is disclosed.

Disclosed are a drunk driving prevention system and a method of controlling the system that includes a sensor module measuring a alcohol content in the exhaled breath of a driver during a breath-checking of the driver and a control module configured to check the intoxication state of the driver from the alcohol content measured by the sensor module to determine whether the breath-checking is complete and block an engine start when the breath-checking fails, wherein the control module includes a check unit displaying breath-checking guide information through a display unit and the check unit displays the breath-checking guide information based on an engine start input of the driver.

A transport device with an occupant compartment includes a control apparatus, a transport device door, a transport device roof, a safety belt, a transport device seat, a headset, a headrest, a rearview mirror, a sun visor, and/or a dashboard, as well as a sensor for breath gas analysis, a position locating device for determining the distance between the sensor and the front side of the head of a compartment occupant, a data processing device, and in some cases a sensor for measuring at least one vital sign. The sensor or sensors are present on or in the control apparatus, the transport device door, the transport device roof, the safety belt, the transport device seat, the headset, the headrest, the rearview mirror, the sun visor, and/or the dashboard, and the data processing device is in operative connection with a device for blocking the transport device and/or with an information output unit.

A vehicle includes a processing device that detects an authentication device approaching the vehicle, determines a user's impaired state based on user condition information acquired using at least one device mounted on the vehicle, and performs a safe driving assistance service. The safe driving assistance service can prevent an impaired user from operating the vehicle.

Disclosed are a drinking under influence (DUI) detection system and a DUI detection method based on an MQ3 sensor and an ultra wide band (UWB) radar. The system includes an alcohol detection module, a respiratory detection module, a signal matching module and a drunk driving alarm module, and each module cooperates to complete a detection. The MQ3 sensor-based alcohol detection module is used for alcohol signal capture, alcohol sequence processing and DUI threshold detection; the UWB radar-based respiratory detection module is used for respiratory signal capture, respiratory signal processing and passenger separation and positioning; the signal matching module is used for periodic signal alignment, sequence feature matching and drinker identity confirmation; and the DUI alarm module is used for a system alarm prompt, a data visualization interface and a DUI information uploading.

Various embodiments provide systems and methods for identifying impairment using measurement devices.

A method of providing safety in a level 3 autonomous vehicle by mounting a plurality of cameras in a vehicular cabin to detect edges; translating the edges into motions of a human or a biological entity; and monitoring safety conditions for the human or biological entity.

A system operable to determine a future point of time, at which the alcohol concentration in blood of a user is less than a threshold value. The system includes an alcohol sensor operable to detect a current alcohol concentration in blood of the user, and a portable apparatus. The alcohol sensor and the portable apparatus each comprise a wireless communication apparatus. The wireless communication apparatus in the alcohol sensor is operable to wirelessly transmit the current alcohol concentration to the wireless communication apparatus in the portable apparatus.

Devices, methods and systems related to wearable patch having blood alcohol content detector. In some embodiments, a wearable patch can include a patch structure having one or more layers and configured to allow the patch to be worn by a user, and an analyzer component implemented on or at least partially within the patch structure and configured to measure alcohol content level in the user. The wearable patch can further include an interface component implemented on or at least partially within the patch structure and in communication with the analyzer component, with the interface component being configured to provide a notification based on the measured alcohol content. In some embodiments, such a wearable patch can be a part of a system such as a monitoring system or a compliance system.
