Vehicle collision mitigation

1. A method for mitigating a vehicle collision, the method comprising:

monitoring for an object within a vehicle travel path;

upon detecting the object within the vehicle travel path, comparing a closing distance rate relative to the object with a closing threshold;

when the closing distance rate does not exceed the closing threshold, determining a plurality of optional secondary vehicle travel paths of the vehicle originating from a current location of the vehicle;

determining, from the plurality of optional secondary vehicle travel paths, a secondary vehicle travel path to produce a determined secondary vehicle travel path which functions to mitigate the closing distance rate, the determined secondary vehicle travel path including an adjacent traffic lane defining an unavailable gap for receiving the vehicle; and

when the closing distance rate exceeds the closing threshold, generating a command data output for transmission to autonomously engage the determined secondary vehicle travel path.

autonomously adjusting a vehicle acceleration based on the determined secondary travel path; and

autonomously adjusting a vehicle heading based on the determined secondary travel path.

3. The method of claim 1 , wherein the determined secondary vehicle travel path includes either a lateral gap or a longitudinal gap as a vehicle objective.

4. A method for mitigating a vehicle collision, the method comprising:

monitoring, via low resolution sensor device data, for an object within a vehicle travel path of a vehicle;

upon detecting an object within the vehicle travel path, comparing a closing distance rate relative to the object with a closing threshold;

when the closing distance rate does not exceed the closing threshold, determining a plurality of optional secondary vehicle travel paths of the vehicle originating from a current location of the vehicle;

determining, from the plurality of optional secondary vehicle travel paths, a secondary vehicle travel path to produce a determined secondary vehicle travel path, wherein the determined secondary travel path functions to mitigate the closing distance rate, the determined secondary vehicle travel path including an adjacent traffic lane defining an unavailable gap for receiving the vehicle;

when the closing distance rate exceeds the closing threshold:

initiating a vehicle control handover to an autonomous operational mode; and

autonomously engaging the determined secondary vehicle travel path.

5. The method of claim 4 , wherein the determining the secondary travel path further comprises:

identifying a first gap defined by a pair of neighboring vehicles adjacent to the vehicle travel path;

when the length of the first gap is less than a length of the vehicle:

autonomously engaging a vehicle deceleration to produce an affected closing distance rate; and

comparing the affected closing distance rate relative to the object with the closing threshold;

when the affected closing distance rate exceeds the closing threshold:

determining the secondary vehicle travel path to intersect with a second gap to

produce the determined secondary vehicle travel path.

6. The method of claim 4 , wherein the determined secondary vehicle travel path further includes at least one of:

an adjacent traffic lane defining a second gap as being available for receiving a vehicle;

an adjacent region defining the second gap as being available for receiving the vehicle; and

the adjacent region defining the second gap as being unavailable for receiving the vehicle.

7. The method of claim 4 , wherein the autonomously engaging the determined secondary travel path further comprises:

autonomously adjusting a vehicle acceleration based on the determined secondary travel path; and

autonomously adjusting a vehicle heading based on the determined secondary travel path.

8. The method of claim 4 , wherein the determined secondary vehicle travel path includes a lateral gap adjacent to the object as an objective.

9. A vehicle control unit comprising:

a communication interface to service communication with a vehicle network;

a processor communicably coupled to the communication interface and a plurality of sensor devices; and

memory communicably coupled to the processor and storing:

an object monitoring module including instructions that, when executed by the processor, cause the processor to:

monitor low resolution sensor device data of at least one of the plurality of sensor devices for an object within a vehicle travel path that;

upon detection of the object within the vehicle travel path, compare a closing distance rate relative to the object with a closing threshold; and

when the closing distance rate exceeds the closing threshold, produce a collision avoidance signal; and

a vehicle collision mitigation module including instructions that, when executed by the processor, cause the processor to:

produce, in response to the collision avoidance signal, a handover command operable to initiate a vehicle control handover to an autonomous operational mode for transmission via the communication interface;

when the closing distance rate does not exceed the closing threshold, determine a plurality of optional secondary vehicle travel paths of the vehicle originating from a current location of the vehicle; and

determine, from the plurality of optional secondary vehicle travel paths, a secondary vehicle travel path to produce a determined secondary vehicle travel path, wherein the determined secondary travel path functions to mitigate the closing distance rate, the determined secondary vehicle travel path including an adjacent traffic lane defining an unavailable gap for receiving the vehicle; and

generate a vehicle action command operable to autonomously engage the determined secondary vehicle travel path for transmission via the communication interface.

10. The vehicle control unit of claim 9 , wherein the determined secondary vehicle travel path further comprises at least one of:

an adjacent traffic lane defining an available gap for receiving a vehicle;

an adjacent region defining the available gap for receiving the vehicle; and

the adjacent region defining the unavailable gap for receiving the vehicle.
