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.

In a computer-implemented method, data about potential vehicle operator impairment is retrieved. The data is generated by monitoring a vehicle operator with a first sensor, monitoring the environment ahead of the vehicle with a second sensor, and monitoring force in one or more directions with a third sensor. A plurality of scores is assigned. Each of the plurality of scores corresponds to a respective impairment indicator, and wherein each of the plurality of scores is based on the data about potential operator impairment. An impairment score is generated by performing a mathematical operation on the plurality of scores. It is determined whether the vehicle operator is impaired by comparing the impairment score to a threshold value. Recommendations to reduce operator impairment of the vehicle operator are identified by analyzing the data about potential vehicle operator impairment.

A system in a vehicle can have a camera and/or a sensor. Such a camera can be configured to record a visual feature of a user in the vehicle and send data derived from the visual feature. Such a sensor can be configured to sense a non-visual feature of the user in the vehicle and send data derived from the non-visual feature. The system can have a computing system configured to receive such data from the camera and the sensor. The computing device can also be configured to determine a state of the user based on the received data derived from visual and non-visual features, as well as an AI system. The computing device can also be configured to enable or disable a function of the vehicle based at least partially on the state of the user, which the AI system can infer from the received data.

A vehicle or a mobile device within or near the vehicle can have multiple sensors to sense biometric features of a user or driver, and electronic circuitry (such as a computing system) can classify the user or driver according to the sensed biometric features. Also, non-biometric factors of the user or driver or of the mobile device of the user or driver can be used to classify the user or driver, e.g., MAC address, RFID, username and password, PIN, etc. Also, factors from interaction with a user interface of the vehicle or the mobile device can be used to classify the user or driver. Such features and factors can be used alone or in combination for the classification, and the classification can use AI (such as an ANN). The vehicle or the mobile device can then selectively enable or disable features of the vehicle based on the classification.

A road information exchange system includes a plurality of Guided Autonomous Information Network (GAIN) units (102) installed on a road. Each GAIN unit (102) communicates with another GAIN unit (102) of the plurality of GAIN units (102) to divide the road into virtual lanes by formation of microgrids and further communicates with a vehicle passing through the road information exchange system (100).

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 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.

A device and a method for preventing driving under influence, may include a first measuring device configured for detecting alcohol in indoor air of a vehicle, and a processor connected to the first measuring device, wherein the processor performs a first check of checking a presence or an absence of the alcohol in the indoor air through the first measuring device before a driver boards the vehicle, performs a second check of checking the presence or the absence of the alcohol in the indoor air through the first measuring device after the driver boards the vehicle, and determines whether there is a possibility that the driver is drunken based on the results of performing the first check and the second check.

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.

A control device of a vehicle including an automated traveling unit capable of executing automated traveling functions includes an acquisition unit for acquiring information regarding a use state of a remote driving service for the vehicle, and a control unit for determining a content of the automated traveling function to be executable by the automated traveling unit based on the use state of the remote driving service for the vehicle. In a case where the vehicle is not using the remote driving service, the control unit disables at least some of the automated traveling functions that are executable in a case where the vehicle is using the remote driving service.
