Systems and methods for intersection assistance using dedicated short range communications
First Claim

1. A host vehicle comprising:
- a dedicated short range communication transceiver that receives safety messages from a stationary transceiver and a first vehicle at a far side of an intersection; and
a processor that, before the host vehicle reaches the intersection;
defines a first zone between a second and third zone before the intersection, sizes of the zones based on a speed of the vehicle; and
when the host vehicle is in the first zone;
based on the received safety messages, predicts whether the first vehicle will render a space available for the host vehicle when the host vehicle clears the intersection and before a traffic light facing the host vehicle turns red; and
determines a recommendation on whether to traverse the intersection based on the prediction; and
a display device that displays the recommendation.

Abstract
Systems and methods for intersection assistance using dedicated short range communications are disclosed. An example vehicle includes a dedicated short range communication transceiver and an intersection assistor. The example dedicated short range communication transceiver is configured to receive safety messages from other vehicles. The example intersection assistor is configured to, before the vehicle reaches an intersection, determine a likelihood that there will be space for the vehicle on the other side of the intersection, and display a recommendation on whether to proceed through the intersection based on the likelihood.

7. A method comprising:
-
receiving, via a dedicated short range communication transceiver of a host vehicle, safety messages from a stationary transceiver and a first vehicle at a far side of an intersection and within a range of a host vehicle; and before the host vehicle reaches the intersection; defining, with a processor of the host vehicle, a first zone between a second and third zone before the intersection, sizes of the zones based on a speed of the host vehicle; when the host vehicle enters the first zone; based on the received safety messages, predicting, with the processor of the host vehicle, whether the first vehicle will render a space available for the host vehicle when the host vehicle clears the intersection and before a traffic light facing the host vehicle turns red; determining, with the processor of the host vehicle, a recommendation on whether to traverse the intersection based on the prediction; and displaying, on a display device, the recommendation. - View Dependent Claims (8, 9, 10, 11, 12, 15)

13. A vehicle comprising:
processors to; before the vehicle reaches an intersection; receive messages from a stationary transceiver and another vehicle at the intersection far side; based on the received messages, predict whether the another vehicle will render a space available for the vehicle when the vehicle clears the intersection and before a traffic light facing the vehicle turns red; and a display device to display a recommendation to traverse the intersection based on the prediction.
