A system may include sensors that may acquire health data related to an individual. The system may also include a processor that may receive trip data associated with a current location of the individual and a destination location for the individual, traffic condition data associated with routes between the current location and the destination location, and weather related data associated with the routes. The processor may also receive the health data from the sensors and determine whether the individual is associated with a driver assessment score above a threshold based on the trip data, the traffic condition data, the weather data, the health data, or any combination thereof. The processor may then send an activation signal to a vehicle control system in response to the driver assessment score being above the threshold, such that the activation signal may enable the vehicle control system to control operations of a vehicle.

A vehicle control system with impaired driver prevention and biometric detection includes a vehicle with an ignition interlock circuit and one or more vehicle electrical systems, a detection device with an internal sensor system, and a mobile device having and one or more biometric sensors. The system operates by initiating a vehicle start command via the mobile device, prompting a user for a scan, receiving the scan from the detection device, whereby the scan includes at least a blood alcohol content percentage of the user, acquiring a sensed biometric image via the biometric sensors of the mobile device, and comparing the sensed biometric image to one or more stored biometric images. If the biometric image does not match a stored biometric image, or if the scan includes a blood alcohol content above a threshold value, then the vehicle start command is canceled.

A vehicular accessory system includes an attachment element adhered at an interior surface of a windshield of a vehicle and an accessory assembly attached to the attachment element. The accessory assembly includes circuitry disposed in the housing, the circuitry including a video camera. The video camera, when the accessory assembly is attached to the attachment element, has a field of view into the interior of the vehicle that encompasses the head of a potential driver of the vehicle. The video camera captures an image of the face of the potential driver and, responsive to image processing by image recognition software of the vehicular accessory system, the vehicular accessory system determines that the potential driver is an authorized driver who is authorized to operate the vehicle and, responsive to this determination, enables the ignition system to allow the motor of the vehicle be started.

The invention relates to a device for determining the driving behavior of a driver, the device comprising at least means for receiving data from two or more data sources, of which at least one produces data relating to changes in the state of motion of a vehicle and at least one other produces measured data on the well-being of the driver; means for scoring the received data by comparing it with data-specific reference values; means for forming a respective sub-index from each scored item of data; means for determining a driving behavior index on the basis of the formed sub-indices; and means for controlling control equipment of the vehicle on the basis of the driving behavior index and/or for storing the driving behavior index in a database.

Methods and apparatus allow for passive determination of a driver's Breath Alcohol Concentration (BrAC). Alcohol concentrations can be determined from exhaled breath, however inconvenience to a driver is often a barrier for incorporation of BrAC sensors into vehicles. The methods and apparatus allow for passive determination of a driver's BrAC, while detecting and accounting for a wide range of environmental conditions that may reduce the accuracy of a passive BrAC reading.

Apparatus for use with a vehicle is disclosed and comprises an interlock device. The device is adapted to, in use: at least while said vehicle is in motion, periodically generate a prompt; assess motion of said vehicle; at least when said vehicle is assessed by said device to be at rest, carry out an analysis operation wherein a breath sample is received and analyzed; and in the event that, within a predetermined period following a prompt, the device does not, while said vehicle is assessed to be at rest, carry out said analysis operation, enter an alarm state at least when the vehicle is in motion. The device can be adapted to carry out analysis operations only when the vehicle is assessed to be at rest.

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.

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 system and method of monitoring sobriety using a hand-held breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station. The breath test signal includes substance content data and user identification data. The substance content data includes at least one of: a blood alcohol level and a narcotics presence. The user identification data includes compressed image data. The signal receiving station is monitored by a supervisor who is able to intervene should the substance level be greater than a predetermined threshold, or should the user identification data no match with a reference user identification data.
