Abstract
Official abstract text for this publication.
A radar system suitable for an automated vehicle includes a radar sensor and a controller. The radar-sensor is mounted on a host-vehicle. The radar-sensor is operable to detect radar-signals reflected by scattering-points of a target-vehicle located proximate to the host-vehicle. The controller is in communication with the radar-sensor. The controller is configured to determine a present-range-rate, a present-azimuth, and optionally a present-range, of each of the scattering-points at a present-time. The controller is also configured to recall a prior-range-rate, a prior-azimuth, and optionally a prior-range, of each of the scattering-points at a prior-time. The controller is also configured to calculate a yaw-rate of the target-vehicle at the present-time based on the present-range-rate, the present-azimuth, the prior-range-rate, and the prior-azimuth, and optionally the present-range and the prior-range, of each of the scattering-points.
First claim
Opening claim text (preview).
We claim: 1. A radar system suitable for an automated vehicle, said system comprising: a radar-sensor mounted on a host-vehicle, said radar-sensor operable to detect radar-signals reflected by scattering-points of a target-vehicle located proximate to the host-vehicle; and a controller in communication with the radar-sensor, said controller configured to determine a present-range-rate and a present-azimuth of each of the scattering-points at a present-time, recall a prior-range-rate and a prior-azimuth of each of the scattering-points at a prior-time, and calculate a yaw-rate of the target-vehicle at the present-time based on the present-range-rate, the present-azimuth, the prior-range-rate, and the prior-azimuth of each of the scattering-points. 2. The system in accordance with claim 1 , wherein the controller is further configured to determine a present-range of each of the scattering-points at a present-time, recall a prior-range of each of the scattering-points at a prior-time, and calculate a yaw-rate of the target-vehicle at the present-time based on the present-range, the present-range-rate, the present-azimuth, the prior-range, the prior-range-rate, and the prior-azimuth of each of the scattering-points. 3. A radar system suitable for an automated vehicle, said system comprising: a radar-sensor mounted on a host-vehicle, said radar-sensor operable to detect radar-signals reflected by scattering-points of a target-vehicle located proximate to the host-vehicle; and a controller in communication with the radar-sensor, said controller configured to determine a present-range, a present-range-rate, and a present-azimuth of each of the scattering-points at a present-time, recall a prior-range, a prior-range-rate, and a prior-azimuth of each of the scattering-points at a prior-time, and calculate a yaw-rate of the target-vehicle at the present-time based on the present-range, the present-range-rate, the present-azimuth, the prior-range, the prior-range-rate, and the prior-azimuth of each of the scattering-points.
