Road characteristic prediction

摘要

A vehicle system includes at least one sensor that collects infrastructure information in real time and outputs sensor signals representing the collected infrastructure information. A processing device processes the sensor signals, predicts a future road characteristic based on the infrastructure information, and controls at least one vehicle subsystem in accordance with the predicted future road characteristic. A method includes receiving infrastructure information collected in real time, processing the infrastructure information, predicting a future road characteristic based on the infrastructure information, and controlling at least one vehicle subsystem in accordance with the predicted future road characteristic.

1. A system comprising:
at least one sensor configured to collect infrastructure information in real time and output sensor signals representing the infrastructure information; and a processing device configured to process the sensor signals, predict a future road characteristic based on the infrastructure information, and control at least one vehicle subsystem in accordance with the predicted future road characteristic, wherein predicting the future road characteristic includes:
observing at least one of a plurality of road characteristics over a predetermined period of time,determining a frequency of occurrence of the at least one of the plurality of road characteristics, andpredicting the future road characteristic based at least in part on whether the at least one of a plurality of road characteristics is observed at least two times over the predetermined period of time and a predicted duration of the at least one of a plurality of road characteristics.
