Abstract

Claims (34)

1 . A driving assistance device comprising:

a processor that executes instructions to:

recognize, as a recognition result, a surrounding situation of a vehicle; and

control at least steering of the vehicle so that the vehicle travels in a travel lane when the vehicle tends to deviate from the travel lane on the basis of the recognition result,

wherein the processor controls the steering of the vehicle by selecting any steering characteristic in accordance with information obtained from an occupant of the vehicle among a plurality of steering characteristics,

wherein the processor causes an output device to output information suggesting a recommended steering characteristic among the plurality of steering characteristics based on a road situation near the vehicle, and

after outputting the information suggesting the recommended steering characteristic, the processor controls steering of the vehicle by switching the steering characteristic to a selected steering characteristic selected by the occupant from among the plurality of steering characteristics

wherein the plurality of steering characteristics include at least a first steering characteristic and a second steering characteristic having a larger steering reaction force of the vehicle than the first steering characteristic.

2 . The driving assistance device according to claim 1 ,

wherein the second steering characteristic has a larger steering reaction force corresponding to a distance from a center of the travel lane of the vehicle than the first steering characteristic.

3 . The driving assistance device according to claim 1 , wherein the processor further executes instructions to:

acquire driving characteristics of the vehicle from the occupant of the vehicle, and

control the steering of the vehicle by selecting any steering characteristic among the plurality of steering characteristics on the basis of the driving characteristics.

4 . The driving assistance device according to claim 1 , wherein the processor further executes instructions to:

acquire an occupant state of the occupant of the vehicle, and

control the steering of the vehicle by selecting any steering characteristic among the plurality of steering characteristics on the basis of the occupant state.

5 . The driving assistance device according to claim 1 , wherein the processor controls the steering of the vehicle by selecting any steering characteristic among the plurality of steering characteristics on the basis of information obtained from the occupant of the vehicle and a road situation near the vehicle.

6 . A driving assistance method comprising:

recognizing, by a computer, a surrounding situation of a vehicle;

controlling, by the computer, at least steering of the vehicle so that the vehicle travels in a travel lane when the vehicle tends to deviate from the travel lane on the basis of the surrounding situation;

controlling, by the computer, the steering of the vehicle by selecting any steering characteristic in accordance with information obtained from an occupant of the vehicle among a plurality of steering characteristics;

causing, by the computer, an output device to output information suggesting a recommended steering characteristic among the plurality of steering characteristics based on a road situation near the vehicle, and

controlling, by the computer, steering of the vehicle by switching the steering characteristic to a selected steering characteristic selected by the occupant from among the plurality of steering characteristics after outputting the information suggesting the recommended steering characteristic

wherein the plurality of steering characteristics include at least a first steering characteristic and a second steering characteristic having a larger steering reaction force of the vehicle than the first steering characteristic.

7 . A computer-readable non-transitory storage medium storing a program for causing a computer to:

recognize a surrounding situation of a vehicle;

control at least steering of the vehicle so that the vehicle travels in a travel lane when the vehicle tends to deviate from the travel lane on the basis of the surrounding situation;

control the steering of the vehicle by selecting any steering characteristic in accordance with information obtained from an occupant of the vehicle among a plurality of steering characteristics;

cause an output device to output information suggesting a recommended steering characteristic among the plurality of steering characteristics based on a road situation near the vehicle, and

control steering of the vehicle by switching the steering characteristic to a selected steering characteristic selected by the occupant from among the plurality of steering characteristics after outputting the information suggesting the recommended steering characteristic

wherein the plurality of steering characteristics include at least a first steering characteristic and a second steering characteristic having a larger steering reaction force of the vehicle than the first steering characteristic.

8 . The driving assistance device according to claim 1 ,

wherein the plurality of steering characteristics further include a third steering characteristic for controlling the steering of the vehicle according to a steering reaction force between the steering reaction force based on the first steering characteristic and the steering reaction force based on the second steering characteristics, and

wherein the processor temporarily controls the steering of the vehicle according to the third steering characteristic when the steering characteristic is switched between the first steering characteristic and the second steering characteristic.
