VEHICLE TECHNOLOGIES FOR AUTOMATED TURN SIGNALING
First Claim
1. A method of automatically activating a turn signal source in a vehicle, the method comprising:
- determining, via a processor, that a first vehicle is going to turn or leave a lane based on data from a first data source of the first vehicle;
determining, via the processor, that a driver of the first vehicle is applying a steering action to the first vehicle based on data from a second data source of the first vehicle;
determining, via the processor, an approximate location of a second vehicle relative to the first vehicle based on data from a third data source of the first vehicle and data from a fourth data source of the first vehicle;
activating, via the processor, a turn signal source of the first vehicle.

Abstract
This disclosure discloses various vehicle technologies for automatically activating a turn signal when a vehicle is turning or changing lanes based on analysis of data, which can include data from an image capture device, radar, a steering angle sensor, and a ultrasonic sensor. This disclosure also contemplates that a decision to automatically activate a turn signal in a vehicle that is turning or changing lanes may take into account whether other vehicles or pedestrians are in vicinity thereof and whether those other vehicles or pedestrians would benefit from the turn signal being activated.

11. A method of automated turn signaling, the method comprising:
-
determining, via a processor, that a vehicle will cross a lane line or turn based on a measured steering angle value that is within a value range stored in a memory or above a threshold value stored in the memory, wherein the vehicle includes the processor, the memory, and the turn signal source; activating, via the processor, the turn signal source based on the determining. - View Dependent Claims (12, 13, 14, 15)

16. A storage device having stored therein a set of processor executable instructions which, when executed by an electronic processing system, cause the electronic processing system to:
-
determine a path of travel of a first vehicle relative to a lane line based on a first set of data received from an image capture device of the first vehicle; determine that a second vehicle is present within a predetermined distance from the first vehicle based on a second set of data received from a reflective wave detector; activate a turn signal source of the first vehicle when (a) the first vehicle has a travel path and a steering angle such that the first vehicle will cross the lane line or effect a turn, and (b) the second vehicle is present within the predetermined distance from the first vehicle.

17. A motor vehicle including a processor;
- a camera;
a steering angle sensor; and
a turn signal source, wherein the processor is programmed to determine when the vehicle is going to turn or leave a lane based on data from at least one of the camera or the steering angle sensor, wherein the processor is programmed to activate the turn signal source when the processor determines that the vehicle is going to turn or leave a lane. - View Dependent Claims (18, 19, 20)
