Abstract
Systems and methods are provided for modulating headlight characteristics according to a calculated probability of future unplanned disengagement of advanced driver-assistance systems or automated driving systems, collectively referred to as driving automation systems. 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 (“DAS”), the method comprising:
- receiving data relating to a future driving environment;
- calculating a likelihood of unplanned disengagement of the DAS based on the data;
- and
- alerting the occupant by modulating headlight characteristics, wherein the intensity of the modulation is proportional with the calculated likelihood of unplanned disengagement of the DAS.
A system of alerting an occupant of a vehicle employing a driving automation system (“DAS”), the system comprising:
- a controller connected to a light mounted to 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 data relating to a future driving environment;
- calculating a likelihood of unplanned disengagement of the DAS based on the data;
- and
- alerting the occupant by modulating headlight characteristics, wherein the intensity of the modulation is proportional with the calculated likelihood of unplanned disengagement of the DAS.
A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:
- receiving data relating to a future driving environment of a vehicle;
- calculating a likelihood of unplanned disengagement of a driving automation system (“DAS”) based on the data;
- and
- alerting an occupant of the vehicle by modulating headlight characteristics, wherein the intensity of the modulation is proportional with the calculated likelihood of unplanned disengagement of the DAS.
