Systems and methods for vehicle-to-vehicle communication
First Claim
1. A vehicle system comprising:
- one or more sub-systems including one or more components;
an inter-vehicle communication system configured to receive and transmit information between a vehicle and one or more other vehicles;
an in-vehicle computing system including a processor and a storage device, the storage device storing functional safety classification data and instructions executable by the processor to;
determine first trust scores for the one or more sub-systems based on a functional safety classification of the sub-system, the functional safety classification based on a functional safety standard;
broadcast the first trust scores of the one or more sub-systems to the one or more other vehicles via the inter-vehicle communication systems;
receive second trust score data from a second vehicle via the inter-vehicle communication system, the second trust score data including a second trust score for one or more second sub-systems of the second vehicle, wherein the second trust score is based on the functional safety standard and indicates reliability of information or data output by each of the one or more second sub-systems; and
adjust one or more actuators of the vehicle system based on the received second trust score data, wherein adjusting the one or more actuators of the vehicle system based on the received second trust score data includes, in response to at least one of the second trust scores below a threshold, adjusting one or more drivetrain actuators to increase a distance between the vehicle and the second vehicle, and wherein the first trust scores and the second trust score have enumerated or integer values to reflect a risk classification scheme of the functional safety standard.

Abstract
Systems and method for vehicle-to-vehicle communication are provided. In one example, a vehicle system may include one or more sub-systems, an in-vehicle computing system, and an inter-vehicle communication system. The in-vehicle computing system may be configured to generate and/or update trust scores for the one or more sub-systems based on a functional safety classification of the one or more sub-systems. The trust scores may be transmitted to one or more other vehicles near the vehicle via the inter-vehicle communication system. The in-vehicle computing system may also receive trust scores from the one or more other vehicles. Based on the received trust scores, the in-vehicle computing system may adjust longitudinal and/or lateral control of the vehicle via one or more actuators.

12. A vehicle system comprising:
-
one or more sub-systems including one or more sensors and one or more actuators; an inter-vehicle communication system configured to receive and transmit information between a vehicle and a second vehicle; an in-vehicle computing system including a processor and a storage device, the storage device storing a first trust score data including a first trust score for the one or more sub-systems and instructions executable by the processor to; receive a second trust score data from the second vehicle via the inter-vehicle communication system, the second trust score data including a second trust score for one or more second sub-systems of the second vehicle; and adjust the one or more actuators of the vehicle system based on the received second trust score data; wherein the first trust score and the second trust score are based on functional safety classifications of the one or more sub-systems and the one or more second sub-systems respectively and wherein the first trust score and the second trust score indicate reliability of information or data output by each of the one or more sub-systems and the one or more second sub-systems, respectively, wherein the second vehicle is a leading vehicle travelling in front of the vehicle in a same lane, and wherein adjusting the one or more actuators of the vehicle based on the received second trust score data includes, in response to at least one of the second trust scores below a threshold, adjusting one or more braking actuators to increase a distance between the vehicle and the second vehicle. - View Dependent Claims (13, 14, 15)

16. A method for an advanced driver assistance system for a vehicle, comprising:
-
receiving a trust score data from a leading vehicle operating in a same lane as the vehicle, the trust score data including a first trust score for a first sub-system of the leading vehicle; during a first condition when the first trust score is greater than a threshold, adjusting one or more actuators of the vehicle to maintain a first threshold separation between the vehicle and the leading vehicle; and during a second condition when the first trust score is less than the threshold, adjusting the one or more actuators of the vehicle to maintain a second threshold separation between the vehicle and the leading vehicle; wherein the first trust score is based on a certified functional safety classification of the first sub-system reflecting an automotive safety integrity level of the first sub-system according to a predefined standard; and wherein the first threshold separation is shorter than the second threshold separation. - View Dependent Claims (17)
