1. A vehicle comprising:
- a sensor to detect an object;
a speed sensor to measure a current speed; and
a collision alerter to;
determine a distance to the object;
determine a time-to-collision based on the distance and the current speed;
emit, in response to the time-to-collision being less than or equal to a first collision threshold, a first alarm associated with the first collision threshold; and
in response to the time-to-collision being greater than the first collision threshold, determine a predicted speed and compare the predicted speed and the current speed.

Abstract
Method, apparatus, and computer storage media are disclosed for vehicle collision warnings based on a time-to-collision. An example vehicle includes a sensor to detect an object, a speed sensor to measure a current speed, and a collision alerter. The example collision alerter is to determine a distance to the object and determine a time-to-collision based on the distance and the current speed. Also, the example collision alerter is to emit, in response to the time-to-collision being less than or equal to a first collision threshold, a first alarm associated with the first collision threshold.

11. A method to emit a vehicle collision warning, the method comprising:
-
detecting an object via a sensor of a vehicle; determining a distance to the object; measuring a current speed of the vehicle via a speed sensor; determining, via a processor, a time-to-collision based on the distance and the current speed; emitting a first alarm in response to the time-to-collision being less than or equal to a first collision threshold; determining, in response to the time-to-collision being greater than the first collision threshold, a predicted speed of the vehicle; and comparing the predicted speed and the current speed. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A vehicle comprising:
-
a sensor to detect an object; a speed sensor; and a collision alerter to; determine a distance to the object; determine a time-to-collision based on the distance and a current speed; emit a first alarm when the time-to-collision is less than or equal to a threshold; and determine and compare a predicted speed to the current speed when the time-to-collision is greater than the threshold.
