Abstract
The present invention relates to devices and methods for detecting the blockage of a radar sensor, and radar apparatuses. The radar sensor blockage detection device may include a first determiner for determining an external environment state based on at least one of external weather data, external image data, and vehicle status data, and determining detection sensitivity according to a result of the determined external environmental state, and a second determiner for determining whether the radar sensor is blocked based on a result of the determined detection sensitivity and signal data of the radar sensor.
Claims15
A device of detecting blockage of a radar sensor, the device comprising:
- a first determiner for determining an external environment state outside of a vehicle or the radar sensor based on at least one of external weather data, external image data, and vehicle status data, and determining detection sensitivity according to the determined external environment state;
- and
- a second determiner for determining whether the radar sensor is blocked based on the determined detection sensitivity and signal data of the radar sensor.
A method of detecting blockage of a radar sensor, the method comprising:
- determine an external environment state outside of a vehicle or the radar sensor based on at least one of external weather data, external image data, and vehicle status data;
- determining detection sensitivity according to the determined external environment state;
- and
- determining whether the radar sensor is blocked based on the determined detection sensitivity and signal data of the radar sensor.
A radar apparatus comprising:
- a radar sensor for transmitting and receiving a radar signal;
- a data acquirer for acquiring at least one of external weather data, external image data, and vehicle status data;
- and
- a controller for determining an external environment state of a vehicle or a radar sensor based on the at least one of the external weather data, the external image data, and the vehicle status data, determining detection sensitivity according to the determined external environment state, and determining whether the radar sensor is blocked based on the determined detection sensitivity and signal data of the radar sensor.
