Solution Overview

Problem

Existing vehicle systems lack the flexibility and security to manage autonomous and assisted driving operations effectively, as they are often limited by physical interconnections and outdated software updating capabilities.

Innovation Solution

A vehicle control system that enforces policies by verifying trusted information from vehicle subsystems, using cryptographic signatures and certificates, and interfacing with policy service systems and devices to ensure safe and secure autonomous operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical interconnections (CAN bus) are used to connect vehicle subsystems, then system reliability is improved, but system flexibility and information exchange capability deteriorate

Engineering Contradiction:

Improvesystem reliabilityVSAvoidsystem flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces the physical mechanical interconnection (CAN bus wiring) with a wireless communication system. Subsystems communicate control commands and status information wirelessly, eliminating the need for physical cable connections while maintaining communication reliability through protocol-level error handling and authentication mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication intermediary layer between subsystems. This intermediary enables flexible information exchange without direct physical connections, allowing subsystems to communicate control commands and status data while maintaining system reliability through authenticated communication protocols.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If cryptographic verification and policy enforcement are implemented, then system security is improved, but system complexity deteriorates

Engineering Contradiction:

Improvesystem securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring cryptographic credentials (certificates and keys) in subsystems before operation. Policy rules and security parameters are established in advance, enabling automatic verification of control commands without real-time complex decision-making, thus reducing operational complexity while maintaining high security.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent enables self-service through automated cryptographic verification and policy enforcement at the subsystem level. Each subsystem independently verifies control commands using pre-configured credentials and automatically enforces policy rules, eliminating the need for centralized complex security management while maintaining high security standards.

Inventive Principle:

Principle #25Self-service

AI summary

This disclosure relates to, among other things, managing the operation of a vehicle in accordance with one or more policies. Consistent with various aspects of the disclosed embodiments, a vehicle control system may be used to enforce policy in connection with various vehicle operations based, at least in part, on trusted information provided by one or more vehicle subsystems and/or other systems. A vehicle control system may verify the received information and use the verified information to determine whether the vehicle may engage in a particular operation and/or enter a particular operational mode in accordance with one or more policies.
