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, where the one or more sub-systems is at least one of a braking system and a drivetrain system;
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 trust scores for the one or more sub-systems based on a functional safety classification of the sub-system; 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.
