20190187241 | LOCALIZATION SYSTEM, VEHICLE CONTROL SYSTEM, AND METHODS THEREOF - According to various aspects, a vehicle localization system is provided, including: a plurality of localization devices configured to receive vehicle position information representing a position of one or more vehicles located in a vicinity of the plurality of localization devices, the plurality of localization devices includes a first set of localization devices and a second set of localization devices, wherein the first set of localization devices is configured to receive additional position information representing a position of one or more localization devices of the second set of localization devices; and one or more processors configured to receive reference position information representing a positional relationship of the localization devices of the first set of localization devices relative to one another, determine a current position of each of the one or more vehicles based on the vehicle position information, the reference position information, and the additional position information. | 2019-06-20 |
20190187242 | System and Method for Determining Vehicle Position Based Upon Light-Based Communication Using Signal-to-Noise Ratio or Received Signal Strength Indicator - A system and method for determining vehicle position uses light based communication (LBC) signals and a received signal strength indicator (RSSI) to determine the vehicle position. Each vehicle includes a LBC system having an array of transmitting light emitting diodes (LEDs) and an array of receiver photodiodes for transmitting and receiving pulsed light binary messages. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes. The controller includes a vehicle communication module that may be executed by a processor to determine the distance. The processor models a first distance between a first transmitting LBC system and a first receiving LBC system, then models a second distance between a second transmitting LBC system and the first receiving LBC system, and then determines the distance between the first vehicle and the second vehicle using trilateration of the first distance and the second distance. | 2019-06-20 |
