Abstract
A driving assistance system according to one embodiment includes: a radar configured to emit a transmission signal around a vehicle, and receive reflected signals reflected from an object around the vehicle; and a processor configured to filter a noise signal included in the reflected signals received by the radar in a rainy environment or snowy environment, wherein the processor sets a filtering condition of the noise signal based on the precipitation amount, determines a reflected signal corresponding to the set filtering condition among the reflected signals received by the radar as the noise signal, and filters the determined noise signal.
Claims20
A driving assistance system for a vehicle, the driving assistance system comprising:
- a radar mounted on the vehicle, and configured to emit a transmission signal around the vehicle and receive reflected signals reflected from an object around the vehicle;
- and
- a processor configured to filter a noise signal included in the reflected signals received by the radar in a rainy environment or snowy environment,
- wherein the processor is configured to set a filtering condition of the noise signal based on precipitation amount, determine a reflected signal corresponding to the set filtering condition among the reflected signals received by the radar as the noise signal, and filter the determined noise signal.
A driving assistance system for a vehicle, the driving assistance system comprising:
- a radar mounted on the vehicle, and configured to transmit a transmission signal around the vehicle, and receive reflected signals reflected from an object around the vehicle;
- and
- a processor configured to cluster the reflected signals to generate a track corresponding to the object,
- wherein the processor is configured to increase a minimum detection amount of the reflected signal for generating the track when precipitation amount is included in a first range, and adjust an antenna beam pattern of the radar to avoid a water spray section when the precipitation amount is included in a second range.
A driving assistance method for a vehicle, the driving assistance method comprising:
- emitting, by a radar mounted on the vehicle, a transmission signal around the vehicle;
- receiving, by the radar, reflected signals reflected from an object around the vehicle;
- and
- filtering a noise signal included in the reflected signals received by the radar in a rainy environment or snowy environment,
- wherein the filtering includes setting a filtering condition of the noise signal based on the precipitation amount, determining a reflected signal corresponding to the set filtering condition among the reflected signals received by the radar as the noise signal, and filtering the determined noise signal.
