Patent number: 11841239Abstract: A host map system for updating a region of a host map based on sensor data received from a plurality of connected vehicles travelling in the region comprises monitoring a host map region for discrepancies, defining a geo-fence around an area of a discrepancy and setting a schedule for activing the geo-fence. When a connected vehicle enters the geo-fence, the host mapping system transmits the geo-fence to the connected vehicle and requests that it share its sensor data while travelling in the geo-fenced area. The host mapping system receives the sensor data and processes the data to update details of the host map. The host mapping system may transmit the updated map to connected vehicles travelling in the map region.Type: GrantFiled: May 9, 2022Date of Patent: December 12, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Randall J.

Patent number: 11748995Abstract: System, methods, and embodiments described herein relate to predicting a future state of an object detected in a vicinity of a vehicle. In one embodiment, a method for predicting a state of an object includes detecting, at a plurality of discrete times [t, t?1, t?2, . . . ], a respective plurality of states of the object, obtaining, based at least in part on a present location of the vehicle, supplemental information, associated with an environment of the present location, that indicates at least a speed reduction factor, executing a prediction operation to determine a predicted state of the object at a time t+1 based at least in part on the detected plurality of states and the supplemental information, determining an actual state of the object at a time t+1 based on data from the one or more sensors, and modifying the prediction operation based at least in part on the actual state.Type: GrantFiled: September 29, 2020Date of Patent: September 5, 2023Assignee: Toyota Research Institute, Inc.Inventors: Schuyler H.

Patent number: 11703335Abstract: A vehicle behavior monitor installed in a host vehicle that monitors the behavior of other vehicles. When the behavior of the other vehicles appears to deviate from an expected trajectory of an in-vehicle map, a geo-fenced region is monitored by external sensors. The external sensor data stream is input to a pre-trained anomaly detector. The clusters from the feature space of the encoder are compared to a database of known behaviors. A confidence level is determined based on the number of vehicles which exhibit the behavior. If the confidence level is equal to or greater than a confidence level threshold, a persistence value is calculate based on the type of behavior. The behavior and the persistence value are used to update the in-vehicle map. Based on the persistence value, the update is transmitted to a map server when the host vehicle enters an area of high data connectivity or is dropped.Type: GrantFiled: June 19, 2020Date of Patent: July 18, 2023Assignee: Toyota Research Institute, Inc.Inventors: Randall J.

Patent number: 11506503Abstract: Methods and a system are described for prioritizing the upload of connected vehicle map data in a central mapping system. A central mapping unit includes a central server which receives and processes data uploads by priority order, from highest priority to lowest priority. The uploaded data is compared to central map data to determine whether the central map requires updating. When the central mapping unit determines that there is not enough information to update the central map in a region, a priority list is updated to give high priority to data collection in the region. The updated priority list is pushed to connected vehicles travelling in the region, which have external sensors for data collection in the surrounding environment. When a connected vehicle enters the region, its external sensors collect data regarding the region, which is uploaded to the central mapping unit with highest priority.Type: GrantFiled: July 9, 2020Date of Patent: November 22, 2022Assignee: TOYOTA RESEARCH INSTITUTE, INC.Inventors: Randall J.

Patent number: 10962984Abstract: The systems and methods described herein disclose detecting objects in a vehicular environment using extracted high level features. As described here, a survey vehicle detects objects in the environment with a survey sensor. Vehicles can then use the extracted features from the survey sensor data to compare with extracted features from input sensor data. Thus, vehicles can benefit from different sensor data without employing said sensor. The systems and methods can include extracting one or more survey features from a survey data set, which can then be mapped to a feature-based map of an environment. An input data set can then be collected using an input sensor type with one or more input features being extracted from the input data set. The one or more input features can then be correlated to the one or more survey features to identify an object in the environment.Type: GrantFiled: November 20, 2018Date of Patent: March 30, 2021Assignee: Toyota Research Institute, Inc.Inventor: Schuyler H.
