Embodiment Construction

[0028] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses.

[0029] see figure 1 , shows a system 10 implemented in a motor vehicle 12 for updating a distributed navigation map to the motor vehicle 12 and other motor vehicles in communication with the blockchain map network 16 . More specifically, system 10 continuously updates the distributed map in a decentralized manner to vehicles communicating with each other in a distributed vehicle-to-vehicle (or peer-to-peer) network. A blockchain is a growing list of blocks connected using cryptography. Each block contains a cryptographic hash, timestamp, and transaction data of previous blocks.

[0030] In certain arrangements, the system 10 includes one or more sensors 18 that detect road changes 14 . Road change 14 is, for example, a lane change, traffic sign, speed limit change, or any other change in road conditions along a roadway as motor vehicle 12 travel...

Abstract

A system for updating a distributed navigation map for a motor vehicle includes one or more sensors that evaluates and characterizes a surrounding around the motor vehicle and a discrepancy detector that identifies differences in the surrounding compared to a known navigation map based on information received from the one or more sensors. The differences are transmitted to a blockchain map network.

Description

technical field [0001] The present disclosure relates to navigation maps for motor vehicles. More specifically, this disclosure relates to decentralized distributed maps using blockchain. Background technique [0002] Currently, many motor vehicles utilize some type of navigation system that provides a driver of the motor vehicle or an automated driving system of an automated motor vehicle with a detailed map of the vehicle's geographic location and directions to a desired destination. However, current mapping systems struggle to remain dynamic without incurring huge costs. [0003] Accordingly, while current navigation mapping systems achieve their intended purpose, new and improved systems and methods for distributed navigation mapping of motor vehicles are needed. Contents of the invention [0004] According to several aspects, a system for updating a distributed navigation map for a motor vehicle includes: one or more sensors evaluating and characterizing the environ...
