Abstract:

A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The breath analyzer detects the breath alcohol level of a vehicle operator and is configured to prevent vehicle ignition if a breath alcohol level is greater than or equal to a threshold value. The controller requires the vehicle operator to periodically take breath analyzer “retests” after vehicle ignition in order to allow vehicle operation to continue. The breath analyzer also detects the presence of alcohol within the vehicle, such as alcohol emanating from an open container of alcohol. The controller may override one or more periodic retests if alcohol is not detected within the vehicle over a predetermined period of time. In addition, the controller may increase the frequency of periodic retests of the vehicle operator in response to detecting alcohol within the vehicle.

US Classification:

180272, 340576, 600532, 180279

Abstract:

A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The breath analyzer detects breath alcohol level of a vehicle operator and prevents vehicle ignition if a breath alcohol level is greater than or equal to a threshold value. The controller requires the vehicle operator to periodically take breath analyzer “retests” after vehicle ignition in order to allow vehicle operation to continue. The breath analyzer includes first and second alcohol sensors. The second alcohol sensor is a backup for the first alcohol sensor and becomes operational if the first alcohol sensor malfunctions. The first or second alcohol sensors may be a mouth contamination sensor that distinguishes between mouth contaminants and alcohol contained within a deep lung breath sample. The system also includes sensors configured to detect impact (abuse) and vehicle motion.

International Classification:

B60K 28/00

US Classification:

180272, 340576

Abstract:

A vehicle ignition interlock system includes a breath analyzer, a transdermal alcohol sensor configured to be worn by the vehicle operator, and a controller operably connected to the breath analyzer, to the transdermal alcohol sensor, and to an ignition system of the vehicle. The transdermal alcohol sensor is configured to be worn by the vehicle operator, and is configured to detect alcohol through the skin of the vehicle operator. The controller is configured to override one or more periodic breath analyzer retests if alcohol is not detected through the skin of the operator by the transdermal alcohol sensor. The controller is configured to increase the frequency of periodic breath analyzer retests of the vehicle operator in response to the transdermal alcohol sensor detecting alcohol through the skin of the operator. A proximity sensor detects proximity of the transdermal alcohol sensor relative to a vehicle operator area.

The controller compares detected breath alcohol levels of the vehicle operator with a threshold value, and is configured to prevent vehicle ignition if a breath alcohol level detected by the breath analyzer is greater than or equal to a threshold value. The controller also requires the vehicle operator to periodically take breath analyzer retests after vehicle ignition in order to allow vehicle operation to continue. The controller can reduce the frequency of periodic retests in response to one or more retests when the breath alcohol level of the vehicle operator is below a threshold value. The system may include a transdermal alcohol sensor, a mouth contamination sensor, a mouth contamination sensor, and redundant alcohol sensors.
