Abstract

A processor-implemented vehicle controlling method includes: determining whether an object in a vehicle is a living object based on radio detection and ranging (radar) information received from a radar sensor; in response to a determination that the object is a living object, determining bioinformation of the object based on the radar information; and adjusting a temperature in the vehicle based on the bioinformation and temperature information received from a temperature sensor.

First claim

What is claimed is:

1. A processor-implemented vehicle controlling method comprising:
determining whether an object in a vehicle is a living object based on radio detection and ranging (radar) information received from a radar sensor when an engine of the vehicle stops or a driver's seat is empty;
in response to a determination that the object is a living object, determining bioinformation of the object based on the radar information;
determining, based on the bioinformation, a temperature profile from among various temperature profiles corresponding to various types of living objects; and
adjusting a temperature in the vehicle based on the temperature profile and temperature information received from a temperature sensor.

2. The method of claim 1 , wherein the determining of whether the object is a living object comprises:
determining whether the object is in the vehicle based on the radar information; and
in response to a determination that the object is in the vehicle, determining whether the object in the vehicle is the living object based on the radar information.

3. The method of claim 2 , wherein the determining of whether the object is a living object comprises:
determining movement information of the object based on the radar information; and
in response to a value of the movement information being greater than or equal to a threshold value, determining the object to be a living object.

4. The method of claim 3 , wherein the determining of whether the object is a living object comprises:
in response to the value of the movement information being less than the threshold value, determining a vibration frequency of the object from the radar information using a Doppler effect; and
in response to the vibration frequency matching a bio-profile, determining the object to be a living object.

5. The method of claim 4 , wherein the vibration frequency comprises a respiratory frequency and a pulse frequency.

6. The method of claim 3 , wherein the determining of the movement information of the object comprises recognizing portions of the object and determining either one or both a relative displacement and relative speed of the portions as the movement information, based on the radar information.

7. The method of claim 1 , wherein the bioinformation comprises any one or any combination of a size of the object, a form of the object, a respiration frequency, and a pulse frequency of the object.

8. The method of claim 1 , wherein the adjusting of the temperature comprises:
determining a type of the object based on the bioinformation; and
adjusting the temperature in the vehicle to match the temperature profile, wherein the temperature profile corresponds to the determined type of the object.

9. The method of claim 8 , wherein the type of the object comprises any one of an adult, child, cat, and dog, and the bioinformation comprises bioinformation of the any one of the adult, child, cat, and dog.

10. The method of claim 8 , wherein
the temperature profile comprises a predetermined normal temperature of the determined type of the object, and
the adjusting of the temperature in the vehicle to match the temperature profile comprises adjusting the temperature in the vehicle such that a difference between the normal temperature and the adjusted temperature in the vehicle is less than or equal to a threshold.

11. The method of claim 8 , wherein
the temperature profile comprises a predetermined normal temperature of the determined type of the object, and
the adjusting of the temperature in the vehicle comprises:
selecting one or more devices among devices of the vehicle based on a difference between the normal temperature and the temperature in the vehicle; and
adjusting the temperature in the vehicle by controlling the selected devices.

12. The method of claim 8 , wherein the adjusting of the temperature in the vehicle comprises:
adjusting the temperature in the vehicle by controlling a cooling device or a heating device of the vehicle.

13. The method of claim 8 , wherein the adjusting of the temperature in the vehicle comprises:
adjusting an amount of light transmitted to an inside of the vehicle by controlling a shading device of the vehicle.

14. The method of claim 1 , further comprising:
transmitting, to an outside of the vehicle, an alarm signal that notifies of a presence or absence of the object based on the bioinformation and the temperature information.

15. The method of claim 1 , further comprising:
unlocking a door lock of the vehicle based on the bioinformation and the temperature information.

16. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, configure the processor to perform the method of claim 1 .

17. A vehicle controlling apparatus comprising:
a radio detection and ranging (radar) sensor configured to radiate a detection signal to an object in a vehicle and receive a reflected signal from the object, and generate radar information by processing the reflected signal; and
one or more processors configured to determine whether the object in the vehicle is a living object based on the radar information when an engine of the vehicle stops or a driver's seat is empty, determine bioinformation of the object based on the radar information in response to the object being determined to be a living object, determine, based on the bioinformation, a temperature profile from among various temperature profiles corresponding to various types of living objects, and adjust a temperature in the vehicle based on the temperature profile and temperature information received from a temperature sensor.

18. The apparatus of claim 17 , wherein, for the adjusting of the temperature, the one or more processors are configured to:
determine a type of the object based on the bioinformation; and
adjust the temperature in the vehicle to match the temperature profile, wherein the temperature profile corresponds to the determined type of the object.

19. The apparatus of claim 17 , wherein, for the adjusting of the temperature, the one or more processors are configured to:
adjust the temperature in the vehicle by controlling a cooling device or a heating device of the vehicle.

20. The apparatus of claim 17 , wherein, for the adjusting of the temperature, the one or more processors are configured to:
adjust an amount of light transmitted to an inside of the vehicle by controlling a shading device of the vehicle.

21. The apparatus of claim 17 , wherein the one or more processors are configured to:
transmit, to an outside of the vehicle, an alarm signal that notifies of a presence or absence of the object based on the bioinformation and the temperature information.

22. The apparatus of claim 17 , wherein the one or more processors are configured to:
unlock a door lock of the vehicle based on the bioinformation and the temperature information.

23. The apparatus of claim 17 , wherein
the apparatus is the vehicle,
the apparatus comprises either one or both of a cooling device and a shading device, and
for the adjusting of the temperature, the one or more processors are configured to adjust the temperature using either one or both of the cooling device and the shading device.

24. The apparatus of claim 17 , further comprising a memory storing instructions that, when executed by the one or more processors, configure the one or more processors to perform the d
