The controller includes a non-transitory storage medium storing instructions for causing the controller to determine a level of attentiveness of a driver of the automotive vehicle and to adapt a response of the driver assistance system in response to the determined level of attentiveness. ## Claims ### Claim 1 An automotive vehicle comprising: a driver analyzer communicatively coupled to a controller; a driver assistance system communicatively coupled to the controller; and the controller including a non-transitory storage medium storing instructions for causing the controller to determine a level of attentiveness of a driver of the automotive vehicle and to adapt a response of the driver assistance system in response to the determined level of attentiveness. ### Claim 2 (depends on 1) The automotive vehicle of claim 1, wherein the driver assistance system is at least one of a brake assist system, a steering assist system, a warning system, an electronic stability control system, an adaptive cruise control system, a collision warning system and a lane departure warning system. ### Claim 3 (depends on 1) The automotive vehicle of claim 1, wherein the non-transitory storage medium further stores instructions for causing said driver assistance system to determine a direction of the driver's focus based at least in part on data from the driver analyzer. ### Claim 4 (depends on 1) The automotive vehicle of claim 1, wherein the driver analyzer is one of a monocular camera, a binocular camera, and an array of cameras. ### Claim 5 (depends on 1) The automotive vehicle of claim 1, wherein the driver analyzer is mounted to a steering column of the automotive vehicle. ### Claim 6 (depends on 1) The automotive vehicle of claim 1, wherein one of the driver analyzer and the controller include a driver recognition module, and wherein the driver recognition module is operable to interpret data from said driver analyzer and thereby determine a specific driver of the vehicle. ### Claim 7 (depends on 1) The automotive vehicle of claim 1, wherein the driver assistance system is a module of said controller. ### Claim 8 (depends on 1) The automotive vehicle of claim 1, wherein the non-transitory storage medium further includes at least one collision avoidance chart, and wherein the collision avoidance chart includes at least a last point to brake data entry and a last point to steer data entry. ### Claim 9 A method of controlling an automotive vehicle comprising: determining a level of a driver's attentiveness by interpreting data from a driver analyzer using a controller; and adjusting a response of a driver assistance system based at least partially on the driver's level of attentiveness. ### Claim 10 (depends on 9) The method of claim 9, wherein the driver assistance system is at least one of a brake assist system, a steering assist system, a warning system, an electronic stability control system, an adaptive cruise control system, a collision warning system and a lane departure warning system. ### Claim 11 (depends on 9) The method of claim 9, further comprising: identifying a specific driver using the controller based on data from the driver analyzer; and loading a specific driver profile from a controller memory, the specific driver profile corresponding to the identified specific driver. ### Claim 12 (depends on 11) The method of claim 11, further comprising adjusting the driver assistance system in response to the specific driver profile. ### Claim 13 (depends on 11) The method of claim 11, wherein identifying a specific driver using the controller based on data from the driver analyzer comprises identifying the specific driver using facial recognition. ### Claim 14 (depends on 9) The method of claim 9, wherein determining the level of the driver's attentiveness by interpreting data from the driver analyzer using a controller comprises: capturing at least one image of the driver using a camera; identifying at least one facial feature of the driver; and determining a facing of the driver relative to a direction of motion of the vehicle based on the position of the at least one facial feature in the at least one image. ### Claim 15 (depends on 14) The method of claim 14, wherein the at least one identified facial feature is at least one of an eye, mouth and nose. ### Claim 16 (depends on 14) The method of claim 14, wherein a high level of attentiveness is determined in response to the driver's facing substantially matching one of the direction of travel of the vehicle and a potential collision object external to the vehicle. ### Claim 17 (depends on 14) The method of claim 14, wherein a low level of attentiveness is determined in response to at least one of the driver's facing and focus direction substantially deviating from at least one of the direction of travel of the vehicle and a potential collision object external to the vehicle. ### Claim 18 (depends on 9) The method of claim 9, wherein adjusting a response of a driver assistance system comprises at least one of delaying a warning point in response to determining a high level of attentiveness and increasing a time period between the warning point and a first of a brake point and a steering point in response to determining a low level of attentiveness. ### Claim 19 (depends on 9) The method of claim 9, further comprising: loading a collision avoidance chart using said driver assistance system, wherein the collision avoidance chart includes compensation for at least one condition external to the vehicle; and wherein adjusting a response of a driver assistance system based at least partially on the driver's level of attentiveness comprises adjusting at least one of a warning point, brake point, steering point, warning intensity and warning location in response to a determined level of driver attentiveness.
