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 the 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 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; and
broadcast the trust scores of the one or more sub-systems to the one or more other vehicles via the inter-vehicle communication system.

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 the 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 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. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. 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 (20)
