Abstract
Systems and methods are provided for modulating longitudinal vehicle dynamics according to a calculated probability of future unplanned disengagement of a driving automation system. In particular, some embodiments aim to alert drivers of both a likelihood of unplanned disengagement, as well as a source of unplanned disengagement.
Claims20
A method of alerting an occupant of a vehicle employing a driving automation system, the method comprising:
- receiving traffic contextual data;
- calculating a likelihood of unplanned disengagement of the driving automation system based on the traffic contextual data;
- and
- alerting the occupant of the unplanned disengagement of the driving automation system by modulating longitudinal vehicle dynamics of the vehicle in accordance with the calculated likelihood of unplanned disengagement of the driving automation system.
A system for alerting an occupant of a vehicle employing a driving automation system, the system comprising:
- a controller for longitudinal vehicle dynamic of the vehicle;
- a processor;
- and
- a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations, the operations comprising;
- receiving traffic contextual data;
- calculating a likelihood of unplanned disengagement of the driving automation system based on the traffic contextual data;
- and
- alerting the occupant of the unplanned disengagement of the driving automation system by modulating longitudinal vehicle dynamics of the vehicle in accordance with the calculated likelihood of unplanned disengagement of the driving automation system.
A non-transitory machine-readable medium of a vehicle employing a driving automation system, having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:
- receiving traffic contextual data;
- calculating a likelihood of unplanned disengagement of the driving automation system based on the traffic contextual data;
- and
- instructing a controller to modulate longitudinal vehicle dynamics of the vehicle in accordance with the calculated likelihood of unplanned disengagement of the driving automation system.
