Operation of a vehicle while suppressing fluctuating warnings
First Claim
1. A method for operating a host vehicle, comprising:
- identifying remote vehicle information indicating a geospatial state and a kinematic state for a remote vehicle;
identifying host vehicle information indicating a geospatial state and a kinematic state for the host vehicle;
for a sequence of sampling points, determining a converging time to a converging location within a transportation network based on the remote vehicle information and the host vehicle information;
modifying operation of the host vehicle to a modified operation responsive the converging time, having been above a first threshold, falling below the first threshold; and
maintaining the modified operation of the host vehicle until the converging time remains above a second threshold higher than the first threshold for a defined number of contiguous sampling points of the sequence.

Abstract
Operating a host vehicle is described as including identifying remote vehicle information indicating a geospatial state and a kinematic state for a remote vehicle and identifying host vehicle information indicating a geospatial state and a kinematic state for the host vehicle. For a sequence of sampling points, a converging time to a converging location within a transportation network is determined based on the remote vehicle information and the host vehicle information. Operation of the host vehicle is modified to a modified operation responsive to the converging time, having been above a first threshold, falling below the first threshold, and the modified operation of the host vehicle is maintained until the converging time remains above a second threshold higher than the first threshold for a defined number of contiguous sampling points of the sequence. A method, vehicle, and apparatus are described.

14. A host vehicle, comprising:
-
a powertrain; a sensor; and an operation system to operate the vehicle, the operation system configured to; identify remote vehicle information indicating a geospatial state and a kinematic state for a remote vehicle; identify, using at least the sensor, host vehicle information indicating a geospatial state and a kinematic state for the host vehicle; for a sequence of sampling points, determine a converging time to a converging location within a transportation network based on the remote vehicle information and the host vehicle information; modify operation of the host vehicle to a modified operation responsive to the converging time, having been above a first threshold, falling below the first threshold; and maintain the modified operation of the host vehicle until the converging time remains above a second threshold higher than the first threshold for a defined number of contiguous sampling points of the sequence or until the remote vehicle information indicates that the remote vehicle is no longer on a converging path with the host vehicle, whichever occurs first. - View Dependent Claims (15, 16)

17. An apparatus for controlling a host vehicle, comprising:
-
a processor; and memory storing instructions that cause the processor to perform a method comprising; identifying remote vehicle information indicating a geospatial state and a kinematic state for a remote vehicle; identifying host vehicle information indicating a geospatial state and a kinematic state for the host vehicle; for a sequence of sampling points, determining a converging time to a converging location within a transportation network based on the remote vehicle information and the host vehicle information; modifying operation of the host vehicle to a modified operation responsive the converging time, having been above a first threshold, falling below the first threshold; and ending the modified operation of the host vehicle, as long as the host vehicle information indicates that the host vehicle is not off, only if at least one of the converging time remains above a second threshold higher than the first threshold for a defined number of contiguous sampling points of the sequence or the remote vehicle information indicates that the remote vehicle is no longer on a converging path with the host vehicle. - View Dependent Claims (18, 19, 20)
