Abstract
Systems and methods implemented in a vehicle involve obtaining elevation information and determining a change in elevation of the vehicle. A method includes determining that the change in elevation indicates an increase or a decrease in the elevation of the vehicle. The method also includes adjusting, for a radar system of the vehicle, a range of detection or a detection threshold that defines a minimum reflected energy required to declare a detection based on the determining that the change in elevation indicates the increase or the decrease in the elevation of the vehicle.
Claims20
A method implemented in a vehicle, comprising:
- obtaining, using a processor, elevation information and determining a change in elevation of the vehicle;
- determining, using the processor, that the change in elevation indicates an increase or a decrease in the elevation of the vehicle;
- and
- adjusting, by the processor, based on the determining that the change in elevation indicates the increase or the decrease in the elevation of the vehicle and as part of a processing of reflections received by a radar system of the vehicle, a range of detection or a detection threshold that defines a minimum criteria required to declare a detection, each of the range of detection and the detection threshold being a parameter used in the processing of the reflections received by the radar system.
A system in a vehicle, the system comprising:
- a global navigation satellite system configured to provide the elevation of the vehicle;
- and
- a processor configured to obtain the elevation of the vehicle and determine that a change in elevation of the vehicle indicates an increase or a decrease in the elevation of the vehicle, and to adjust, based on the change in elevation being the increase or the decrease in the elevation of the vehicle and as part of a processing of reflections received by a radar system of the vehicle, a range of detection or a detection threshold that defines a minimum criteria required to declare a detection, each of the range of detection and the detection threshold being a parameter used in the processing of the reflections received by the radar system based.
