Method and apparatus for determining a target vehicle position from a source vehicle using a radar

摘要

A sensing system (10) for an automotive vehicle includes a first radar sensor (18) generating a first and a second range signal, and a second radar sensor (20) generating a first and a second range signal corresponding to two sampling time periods. A controller (12) is coupled to the first radar sensor (18) and the second radar sensor (20). The controller (12) calculates a first position and a second position from the first radar sensor and the second radar sensor range measurements. The controller (12) generates a first set of points corresponding to the first position and a second set of points corresponding to the second position. The controller (12) calculates a plurality of calculated range-rate values in response to the first set of points and the second set of points. The controller (12) compares the plurality of calculated range-rate values to the measured range-rate and selects the closest range-rate from the plurality of calculated range-rate values. A couple of target position points is generated from the first set of points and the second set of points corresponding to the calculated closest range-rate.
