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, for a radar system of the vehicle, a range of detection or a detection threshold that defines a minimum criteria 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.
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, for a radar system of the vehicle, a range of detection or a detection threshold that defines a minimum criteria required to declare a detection based on the change in elevation being the increase or the decrease in the elevation of the vehicle.
