Abstract

A method includes, responsive to a turn signal tap by an operator of a vehicle, controlling an external turn signal indicator to provide a turn signal for a pre-determined duration, the turn signal visible to operators of other vehicles, determining an intended driving maneuver of the vehicle by the operator, and determining a location of the vehicle relative to the intended driving maneuver. The method also includes determining, based on the intended driving maneuver and the location, a turn indication score representing whether the intended driving maneuver is complete, based on the turn indication score satisfying a criterion, controlling the external turn signal indicator to continue the turn signal past the pre-determined duration, and, based on the turn indication score not satisfying the criterion, controlling the external turn signal indicator to de-activate the turn signal.

Claims19

Dependent claims

A vehicle comprising:

a turn signal lever configured to detect a turn signal tap by an operator of the vehicle, the turn signal tap activating a turn signal having a pre-determined duration;
an external turn signal indicator configured to, responsive to detection of the turn signal tap, provide the turn signal, the turn signal visible to operators of other vehicles;
data processing hardware;
and
memory hardware in communication with the data processing hardware and storing instructions that, when executed by the data processing hardware, cause the data processing hardware to perform operations responsive to the turn signal tap, the operations comprising:
determining an intended driving maneuver of the vehicle by the operator;
determining a location of the vehicle relative to the intended driving maneuver;
determining, based on the intended driving maneuver and the location, a turn indication score representing whether the intended driving maneuver is complete;
based on the turn indication score satisfying a criterion, controlling the external turn signal indicator to continue the turn signal past the pre-determined duration;
and
based on the turn indication score not satisfying the criterion, controlling the external turn signal indicator to de-activate the turn signal.

A computer-implemented method executed by data processing hardware that causes the data processing hardware to perform operations responsive to a turn signal tap by an operator of a vehicle, the operations comprising:

controlling an external turn signal indicator to provide a turn signal for a pre-determined duration, the turn signal visible to operators of other vehicles;
determining an intended driving maneuver of the vehicle by the operator;
determining a location of the vehicle relative to the intended driving maneuver;
determining, based on the intended driving maneuver and the location, a turn indication score representing whether the intended driving maneuver is complete;
based on the turn indication score satisfying a criterion, controlling the external turn signal indicator to continue the turn signal past the pre-determined duration;
and
based on the turn indication score not satisfying the criterion, controlling the external turn signal indicator to de-activate the turn signal.
