A system and method of bio-cleaning an ignition interlock device (IID). The method comprises receiving a handheld unit of an IID in a fixtured arrangement with an IID calibration station, and applying, while maintaining the IID handheld unit in the fixtured arrangement, a bio-cleaning agent to at least one ingress port of the IID handheld unit in a consolidated IID bio-cleaning and IID calibration operation.

A movable carrier auxiliary system includes a driver state detecting device and a warning device. The driver state detecting device includes a physiological state detecting module, a storage module, and an operation module. The physiological state detecting module is adapted to detect a physiological state of a driver. The storage module is disposed in a movable carrier and stores an allowable parameter corresponding to the at least one physiological state. The operation module is disposed in the movable carrier and is electrically connected to the physiological state detecting module and the storage module to detect whether the at least one physiological state of the driver exceeds the allowable parameter or not, and to correspondingly generate a detection signal. The warning device generate a warning message when the detection signal that the at least one physiological state of the driver exceeds the allowable parameter is received.

An interlock control system linked to a digital key includes an alcohol interlock controller, which calculates a decomposition time period required to decompose blood alcohol of each driver using personal information of the driver, extracted by authenticating a digital key, when a blood alcohol concentration measured by an alcohol measuring sensor exceeds a reference value. The alcohol interlock controller then restricts ignition of a vehicle using the digital key for the decomposition time period. By calculating and providing the decomposition time period for restricting the ignition of the vehicle, based on the personal information and an actual alcohol clearance of the driver, predicted information on a time point for allowing the driver to drive the vehicle is provided to the driver. An interlock control method for the same is also provided.

A method and a system of deploying an ignition interlock device (IID). The method comprises receiving a time series of breath alcohol content (BrAC) measurements that are unitarily sourced from a pre-identified user, each BrAC measurement of the time series including an alveolar breath component and an interferent breath component; estimating a dissipation rate of alcohol attributable to the pre-identified user in accordance with the time series of BrAC measurements; determining, responsive to estimating the dissipation rate of alcohol, at least a subset of the BrAC measurements as being based on the alveolar breath component but not the interferent breath component; and performing one of triggering and not triggering the IID into a lockout state based on the at least a subset of the BrAC measurements.

Disclosed is a system and method for determining a driver's inebriation in a vehicle. The system includes a breathalyzer configured to be provided in an interior space of the vehicle to determine whether the driver is inebriated, through a driver's exhalation; and a controller configured to output a movement request signal for a driver's seat when determination of driver's inebriation by the breathalyzer is required and to control the breathalyzer to start the determination of driver's inebriation when the movement of the driver's seat is completed.

A driving assistance device includes a determination unit to, when a vehicle is transitioned to a movable state by start of driving assistance of the vehicle and a display related to the driving assistance is presented, determine whether or not a driver is in a drivable state in which the driver is capable of consciously performing an operation, based on whether or not the driver has recognized the display, and a control unit to allow acceptance of the operation when the determination unit determines that the driver is in the drivable state.

Systems and methods are disclosed configured to detect impairment issues, and via an interlock device, inhibit operation of an item of equipment when impairment is detected. The interlock device may comprise a solid state relay, an electromechanical relay, and/or a solenoid. The interlock device may perform power isolation and/or may use a mechanism, such as a rotating cam or gear, to immobilize a control and/or other components. Based on detected impairment, a determination is made as to whether the interlock is to be activated or deactivated.

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.

A focused driving system ties a driver's cell phone to the systems of the car that allow for its operation. A microcontroller monitors the cell phone for activity by the driver and disables the car if the cell phone is in use. The cell phone is linked to the microcontroller to facilitate the monitoring of the phone.

An in-vehicle apparatus (1) according to the present disclosure includes: estimated walking path acquisition means (21) for acquiring an estimated walking path, which is a path in which it is estimated that a driver will walk; and drinking determination means (22) for determining whether or not the driver is drunk based on a walking pattern of the driver in the estimated walking path.
