private , auditable vehicle positioning system and for him to come on-board unit

摘要

This invention relates to a system and method to generate a private, auditable, evidentiary quality record of the location-history of an asset or person. This invention addresses ten critical improvements over existing systems that are proposed or used for metering for payment services for tolling roads, parking or pay-as-you-drive insurance, namely, cost-effective location accuracy in harsh signal environments, evidentiary assurance of location estimation, handling of dynamic and stationary positioning in a single device, high-ratio compression for a set of stationary positions in urban canyon, high-ratio compression for a dynamic tracklog in urban canyon, high-ratio compression for a set of asset motion behaviors, a method of remote device health check, including anti-tampering, removal of residual price assignment errors, anonymous use without on-board maps, and a method of deconsolidating payments to multiple payees with multiple payment regimes. This system can be applied to road-pricing, congestion-pricing, metered-by-the-minute parking and pay-as-you-drive insurance, incorporating privacy management, and legal admissibility of the evidentiary record. This same device can also be applied to vehicular fleets, military ordinance, or other location audits for assets whether motorized or not, as might be needed in evidence of contract fulfillment or other forms of non-realtime geofencing audits.
