Driver alert system through algorithmic braking events for advanced driver-assistance system

An advanced driver-assistance system (ADAS) method a vehicle, the ADAS method comprising:

• establishing, by a controller of the vehicle, communication with (i) an anti-lock braking system (ABS) configured to apply a braking force at a driveline of the vehicle, (ii) a driver monitoring system configured to monitor an attentiveness and/or vehicle interactivity by a driver of the vehicle, and (iii) an audio/visual/haptic (AVH) alert system configured to generate an AVH output for the driver including at least one of an audio alert, a visual alert, and a haptic alert;
• initiating, by the controller, an ADAS event during which the controller at least partially takes control of the vehicle from the driver;
• and
• during the ADAS event:
• detecting, by the controller and using at least the driver monitoring system (i) a driver attentiveness level and (ii) a control urgency level indicative of how important it is for the driver to potentially retake control of the vehicle;
• based on the detected driver attentiveness level and the detected control urgency level, determining, by the controller, a desired driver alert level for attempting to regain the driver's attention for the driver to potentially retake control of the vehicle,
• wherein the desired driver alert level is determined from a plurality of predetermined driver alert levels each including at least one of (i) an AVH alert and (ii) a degree of a braking event;
• and
• commanding, by the controller, at least one of the AVH alert system and the ABS according to the desired driver alert level.

An advanced driver-assistance system (ADAS) for a vehicle, the vehicle ADAS comprising:

• an anti-lock braking system (ABS) means for apply a braking force at a driveline of the vehicle;
• a driver monitoring means for monitoring an attentiveness and/or vehicle interactivity by a driver of the vehicle;
• an audio/visual/haptic (AVH) alert means for generating an AVH output for the driver including at least one of an audio alert, a visual alert, and a haptic alert;
• and
• a controller means in electronic communication with the ABS means, the driver monitoring means, and the AVH alert means, and for
• initiating an ADAS event during which the controller means at least partially takes control of the vehicle from the driver;
• during the ADAS event, detecting, using at least the driver monitoring means, (i) a driver attentiveness level and (ii) a control urgency level indicative of how important it is for the driver to potentially retake control of the vehicle;
• based on the detected driver attentiveness level and the detected control urgency level, determining a desired driver alert level for attempting to regain the driver's attention for the driver to potentially retake control of the vehicle,
• wherein the desired driver alert level is determined from a plurality of predetermined driver alert levels each including at least one of (i) an AVH alert and (ii) a degree of a braking event;
• and
• commanding at least one of the AVH alert means and the ABS means according to the desired driver alert level.
