Solution Overview
Problem
Automated Driving Systems (ADS) face limitations in processing capability due to hardware and power resource constraints, restricting the amount of input data that can be utilized and the sophistication of algorithms, which hinders the addition of new functionality without increasing size, power consumption, and cost.
Innovation Solution
A method that involves locally processing sensor data to generate a local world-view and transmitting it to a remote system for supplementary processing, forming an augmented world-view by combining local and off-board processed data, allowing for increased computational capabilities without significant impact on the on-board system's size, power, and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If more processing capability is added to the on-board system to improve environmental awareness, then the representation of surroundings is improved, but the size, power consumption and cost of the on-board system increase
Solution Approach 1:
The patent segments the processing tasks between on-board and off-board systems. The on-board system performs essential real-time processing while the off-board system handles supplementary processing tasks. This segmentation allows the vehicle to achieve enhanced environmental awareness through multiple camera inputs without requiring all processing capability to be present on-board, thus avoiding excessive power consumption and hardware costs.
2Measurement precision
If more processing capability is added to the on-board system to improve environmental awareness, then the representation of surroundings is improved, but the size and cost of the on-board system increase
Solution Approach 1:
The system divides processing responsibilities between on-board and off-board components. The on-board system contains only essential processing hardware while supplementary processing is performed off-board. This segmentation enables enhanced environmental awareness through multiple camera inputs without proportionally increasing on-board system size and complexity.
Solution Approach 2:
The patent introduces an intermediary off-board processing system that receives data from on-board sensors and returns processed information to the vehicle. This intermediary approach allows complex processing tasks to be performed externally, reducing the need for large on-board processing hardware while still achieving enhanced environmental awareness.
3Measurement precision
If more sophisticated algorithms are used to improve environmental awareness, then the representation of surroundings is improved, but the processing requirements and power consumption increase
Solution Approach 1:
The patent segments algorithmic processing between on-board and off-board systems. Essential real-time processing occurs on-board while more computationally intensive supplementary processing occurs off-board. This segmentation allows sophisticated algorithms to be used for environmental awareness without overwhelming on-board processing efficiency requirements.

AI summary
The present disclosure relates to a method for augmenting capabilities of an Automated Driving System (ADS) of a vehicle. The method includes locally processing, by means of a perception module of the ADS, sensor data obtained from one or more sensors of the vehicle in order to generate a local world-view of the ADS, wherein the sensor data includes information about a surrounding environment of the vehicle. The method further includes transmitting sensor data including information about the surrounding environment of the vehicle to a remote system, and receiving off-board processed data from the remote system, the off-board processed data being indicative of a supplementary world-view of the ADS. Furthermore, the method includes forming an augmented world-view of the ADS based on the generated local world-view and the supplementary world-view.
