Abstract
Overcoming localization errors in geographic regions where a global positioning system signal is obstructed is provided. A system can identify a geographic location with a localization error. In response, the system can supplement the global positioning system data associated with the geographic location with supplemental data to generate supplemental global positioning system data. Additionally, an operational state of a vehicle is controlled based on the supplemental global positioning system data.
Claims20
A system, comprising:
- a data processing system comprising one or more processors, coupled with memory to:
- identify a geographic location with a localization error, wherein the geographic location is identified based on global positioning system (GPS) data and the localization error is determined based on classification of vehicles with the localization error and conditional data associated with the identified geographic location;
- determine that a power level of a GPS signal associated with the GPS data at the geographic location is less than a threshold to identify that the geographic location exhibits the localization error;
- in response to identifying the localization error, obtain supplemental data associated with the geographic location;
- generate supplemental GPS data associated with the geographic location, wherein the supplemental GPS data includes the supplemental data associated with the geographic location;
- facilitate control of an operational state of a vehicle based on the supplemental GPS data, the facilitation comprising restricting an operation of a plurality of operations of an advanced driver assistance system (ADAS), the plurality of operations comprising an adaptive cruise control operation, partial driving automation mode, or full driving automation mode;
- and
- display an alert on a user interface of the vehicle identifying a change in operational state of the vehicle.

A method, comprising:
- identifying, by a data processing system comprising one or more processors coupled with a memory, a geographic location with a localization error, wherein the geographic location is identified based on global positioning system (GPS) data and the localization error is determined based on classification of vehicles with the localization error and conditional data associated with the identified geographic location;
- determining that a power level of a GPS signal associated with the GPS data at the geographic location is less than a threshold to identify that the geographic location exhibits the localization error;
- in response to identifying the localization error, obtaining, by the data processing system, supplemental data associated with the geographic location;
- generating, by the data processing system, supplemental GPS data associated with the geographic location, wherein the supplemental GPS data includes the supplemental data associated with the geographic location;
- facilitating, by the data processing system, control of an operational state of a plurality of operational states of a vehicle based on the supplemental GPS data, the facilitation comprising enabling an advanced driver assistance system (ADAS), the plurality of operational states comprising an adaptive cruise control of operation, a partial driving automation mode, and a full driving automation mode;
- and
- displaying, by the data processing system, an alert on a user interface of the vehicle identifying a change in operational state of the vehicle.

A system, comprising:
- a data processing system comprising one or more processors, coupled with memory to:
- identify a geographic location exhibiting a localization error, wherein the geographic location is identified based on global positioning system (GPS) data and the localization error is determined based on classification of vehicles with the localization error and conditional data associated with the identified geographic location;
- determine that a power level of a GPS signal associated with the GPS data at the geographic location is less than a threshold to identify that the geographic location exhibits the localization error;
- determine that a route of a vehicle passes through the geographic location;
- in response to identifying the localization error and determining that the route passes through the geographic location, obtain supplemental data associated with the geographic location;
- generate supplemental GPS data associated with the geographic location, wherein the supplemental GPS data includes the supplemental data associated with the geographic location;
- navigate the route according to an operational state of the vehicle, wherein the operational state comprises a restriction for an operation of a plurality of operations of an advanced driver assistance system (ADAS), based on the supplemental GPS data, the plurality of operations comprising an adaptive cruise control operation, partial driving automation mode, or full driving automation mode;
- and
- display an alert on a user interface of vehicle identifying a change in operational state of the vehicle.
