The distraction system can be part of a vehicle seating system, A vehicle seating system is described and includes a seat configured to support an occupant and to be mounted in a vehicle and occupant sensing system at least partially integrated into the seat to sense an occupant. The sensing system senses a first criterion with respect to the occupant. A controller is configured to receive the first criterion signal from the sensing system and a second criterion to determine a distraction state of the driver. The controller can also determine a false distraction state using the distraction state and other criterion in a vehicle. The controller outputs a control signal when the distraction state exceeds a distraction threshold and when distraction is confirmed. ## Claims ### Claim 1 A system, comprising: an electro-dermal potential sensing system integrated into the vehicle cabin to sense a person and configured to output an electro-dermal potential signal; at least one additional vehicle sensor to sense vehicle-related data; and a controller to receive the electro-dermal potential signal from the electro-dermal potential sensing system and the vehicle sensor to determine a distraction state of the person using both the electro-dermal potential signal and the vehicle-related data to reduce the likelihood of a false distraction state using only one of the vehicle-related data or the electro-dermal potential signal, the controller is to output a control signal when the distraction state is determined and confirmed not false. ### Claim 2 (depends on 1) The system of claim 1, wherein the controller is configured to determine a false distraction state based in both the vehicle-related data and the electro-dermal potential signal. ### Claim 3 (depends on 1) The system of claim 1, wherein the control signal is to adjust operation of an adaptive braking system in the vehicle. ### Claim 4 (depends on 1) The system of claim 1, further comprising a seat configured to support the person as an occupant and to be mounted in a vehicle; and wherein the electro-dermal potential sensing system includes a contactless sensor mounted in the seat adjacent a head of the occupant. ### Claim 5 (depends on 4) The vehicle seating system of claim 4, wherein the electro-dermal potential system includes a plurality of contactless sensors mounted in the seat; and wherein the seat includes a head rest, and wherein the plurality of contactless sensors includes one or more headrest sensors mounted in the headrest to measure electro-dermal potential at a head of the driver. ### Claim 6 (depends on 4) The vehicle seating system of claim 4, wherein the seat includes a driver warning device to indicate to the driver that the control signal is output from the controller. ### Claim 7 (depends on 1) The vehicle seating system of claim 1, wherein the controller measures driver distraction based on individual frequency components in the electro-dermal potential signal. ### Claim 8 (depends on 1) The vehicle seating system of claim 1, wherein the controller uses the electro-dermal potential signal to determine distraction of the person and when distraction is detected outputs the control signal to increase a time to impact variable in an object avoidance calculation. ### Claim 9 (depends on 8) The vehicle seating system of claim 8, wherein the sensor signals include a video image output from a cabin camera to detect the person, and wherein the controller uses the video output and the electro-dermal potential signal to determine the false distraction state of the person. ### Claim 10 (depends on 8) The system of claim 8, wherein the sensor signals include a navigational position signal from a navigational position sensor to detect position of a vehicle, and wherein the controller uses the navigational position signal and the electro-dermal potential signal to determine the false distraction state of the person. ### Claim 11 (depends on 8) The system of claim 8, wherein the sensor signals include an external camera signal from an outward facing imager to produce video external to the vehicle, and wherein the controller uses the external camera signal and the electro-dermal potential signal to determine the false distraction state of the person. ### Claim 12 (depends on 1) The system of claim 1, wherein the sensor signals include an internal video signal, an external camera signal, a navigational position signal, and a vehicle speed signal, and wherein the controller uses internal video signal, an external camera signal, the navigational position signal, the vehicle speed signal and the electro-dermal potential signal to determine the false distraction state of the driver. ### Claim 13 A vehicle system, comprising: a vehicle safety sensor system configured to sense external objects around the vehicle and output an external sensor signal; a seat configured to support an occupant and to be mounted in a vehicle; an electro-dermal potential system at least partially integrated into the vehicle cabin and configured to output an electro-dermal potential signal; and a controller to receive the electro-dermal potential signal from the electro-dermal potential system and the external sensor signal and to output a control signal, using the electro-dermal potential signal and the external sensor signal, to adjust operation of the vehicle safety sensor system in the vehicle. ### Claim 14 (depends on 13) The vehicle system of claim 13, wherein the electro-dermal potential system includes a plurality of contactless sensors mounted in the seat. ### Claim 15 (depends on 13) The vehicle system of claim 13, wherein the vehicle safety sensor system includes a detection and ranging system with a range setting to sense objects outside including a position and a range of an external object and the external sensor signal includes the position and range of the external object. ### Claim 16 (depends on 15) The vehicle system of claim 15, wherein the controller outputs a range extension signal when the controller determines that the driver is distracted using the electro-dermal potential signal, and wherein the vehicle safety system extends the range setting when the controller outputs the range extension signal. ### Claim 17 (depends on 13) The vehicle system of claim 13, further comprising a collision avoidance system having a trigger time based on the control signal from the controller, and wherein the collision avoidance system triggers an avoidance action based on the trigger time ### Claim 18 (depends on 17) The vehicle system of claim 17, wherein the collision avoidance system has a first trigger time when distraction is not detected and a second trigger time when distraction is detected, the second trigger time being less than the first trigger time. ### Claim 19 A vehicle system, comprising: a first sensor to sense a first criterion relating to distracted driving and controlled by the driver; a second sensor to sense a second criterion relating to distracted driving and representing an environmental condition not controlled by the driver; and a controller to receive the first criterion and the second criterion and determine a relative relationship between the first criterion and the second criterion with the relative relationship exceeding a distractedness threshold to indicate distracted driving. ### Claim 20 (depends on 19) The vehicle system of claim 19, wherein the first criterion is vehicle speed, wherein the second criterion is traffic congestion, other vehicles speeds adjacent the vehicle, or a combination of both, and the controller compares the vehicle speed relative to the second criterion, and wherein when the vehicle speed slows relative to the second criterion, the controller will indicate distractedness of the driver.
