US 12,709,303 B2 · Function allocation and integration for autonomous vehicles

Abstract

This invention presents a function allocation system for an autonomous vehicle (AV). During the operations of the AV, some or all of its automated driving capabilities or functions could be downgraded due to long-tail events or malfunctioning. The roadside intelligent infrastructure, or the cloud platform, could supplement some or all of AV's automated driving functions, including sensing, prediction and decision-making, and/or control functions. The function allocation system dynamically allocates these functions between AV and intelligent infrastructure, achieving a higher system intelligence level S than the downgraded vehicle intelligence level V. In addition, a function allocation system could dynamically allocate sensing, prediction and decision-making, and/or control functions between AV and a cloud platform. This invention also presents a function integration system or a fusion system for an AV. The fusion system integrates data across these functions to optimize automated driving performance and collaboration between AV and intelligent infrastructure.

Dependent claims

A function allocation system for an automated driving system (ADS), said function allocation system comprising one or more of a sensing allocation system;

a prediction and decision-making allocation system;
and/or a control allocation system,
wherein said ADS system operates at a system intelligence level S=1, 2, 3, 4, or 5 during vehicle operation by identifying a vehicle intelligence level V of said vehicle during vehicle operation and identifying an infrastructure intelligence level I of said infrastructure during vehicle operation;
and
wherein said function allocation system is configured to allocate one or more of sensing, prediction and decision-making, and/or control functions to the vehicle based on the vehicle intelligence level V and to the infrastructure based on the infrastructure intelligence level I to support said ADS system with system intelligence S that is greater than the vehicle intelligence level V and/or that is greater than the infrastructure intelligence level I so that the ADS system manages the vehicle and the infrastructure to facilitate vehicle operations and controls during vehicle operation.

2 more elements

A function allocation system for an automated driving system (ADS), said function allocation system comprising a prediction and decision-making allocation system configured to allocate prediction and decision making functions,

wherein said ADS system operates at a system intelligence level S=1, 2, 3, 4, or 5 during vehicle operation by identifying a vehicle intelligence level V of said vehicle during vehicle operation and identifying an infrastructure intelligence level I of said infrastructure during vehicle operation;
and
wherein said function allocation system is configured to allocate prediction and decision-making functions to the vehicle based on the vehicle intelligence level V and to the infrastructure based on the infrastructure intelligence level I to support said ADS system with system intelligence S that is greater than the vehicle intelligence level V and/or that is greater than the infrastructure intelligence level I so that the ADS system manages the vehicle and the infrastructure to facilitate vehicle operations and controls during vehicle operation.
