Abstract
A method and system for estimating an absolute velocity of an obstacle are provided. The method can include measuring an absolute velocity of a motor vehicle at a current moment tby an integrated navigation device, and storing the measured absolute velocity of the motor vehicle at the current moment tin a data table, obtaining a relative velocity of the obstacle relative to the motor vehicle at a second moment tby a millimeter wave radar; adjusting the relative velocity of the obstacle at the second moment tto a relative velocity of the obstacle at the current moment t, and obtaining the absolute velocity of the obstacle at the current moment tby adding the absolute velocity of the motor vehicle at the current moment tto the relative velocity of the obstacle at the current moment tafter an adjustment.
