Abstract

A movement trajectory generator 1 that generates a movement trajectory of a vehicle is provided, which includes traveling environment recognition means 10, 11, and 21 for recognizing a traveling environment, movement strategy generation means 22 for generating movement strategies for positioning in a road area according to the traveling environment that is recognized by the traveling environment recognition means, presenting means 12, 23, and 27 for presenting a passenger setting information of the movement strategies, setting means 12 and 28 for receiving an operation for the passenger to set the movement strategies based on the setting information of the movement strategies presented by the presenting means, and movement trajectory generation means 29 for generating the movement trajectory based on the movement strategies set by the setting means.

Claims

1. A movement trajectory generator that generates a movement trajectory of a vehicle, comprising:

traveling environment recognition means for recognizing a traveling environment;

movement strategy generation means for generating at least one candidate of movement strategies for positioning in a road area according to the traveling environment that is recognized by the traveling environment recognition means;

presenting means for presenting a passenger with the candidate of the movement strategies, the presenting means presents a plurality of movement strategy candidates;

setting means for receiving an operation for the passenger to set the candidate of the movement strategies presented by the presenting means, the setting means receives a passenger'"'"'s operation of selecting one of the plurality of movement strategy candidates;

degree of risk acquisition means for acquiring a degree of risk according to the movement strategy candidates, the presenting means presents the plurality of movement strategy candidates together with the degree of risk acquired by the degree of risk acquisition means; and

movement trajectory generation means for generating the movement trajectory based on the movement strategies set by the setting means.

2. The movement trajectory generator according to claim 1, wherein the setting means receives a passenger'"'"'s correction operation of the movement strategies.

3. The movement trajectory generator according to claim 2, further comprising degree of risk acquisition means for acquiring a degree of risk according to the movement strategies,

wherein the setting means changes an ease of correction of the movement strategies according to the degree of risk acquired by the degree of risk acquisition means.

4. The movement trajectory generator according to claim 1, further comprising detection means for detecting a passenger'"'"'s observation area,

wherein the presenting means presents a setting information of the movement strategies in the observation area detected by the detection means.

5. The movement trajectory generator according to claim 1, wherein the presenting means presents a factor for setting the movement strategies.

6. The movement trajectory generator according to claim 1, wherein the traveling environment recognition means recognizes a state of surrounding objects, and

the presenting means also presents the state of the surrounding objects recognized by the traveling environment recognition means.

7. The movement trajectory generator according to claim 1, wherein the display presents a factor for setting the movement strategies.

8. The movement trajectory generator according to claim 1, wherein the surrounding environment recognition unit recognizes a state of surrounding objects, and

the display also presents the state of the surrounding objects recognized by the surrounding environment recognition unit.

9. A movement trajectory generator that generates a movement trajectory of a vehicle, comprising:

a surrounding environment recognition unit for recognizing a traveling environment;

a movement strategy setting unit for generating at least one candidate of movement strategies for positioning in a road area according to the traveling environment that is recognized by the surrounding environment recognition unit;

a display for presenting a passenger with the candidate of the movement strategies, the display presents a plurality of movement strategy candidates;

a movement strategy setting unit for receiving an operation for the passenger to set the candidate of the movement strategies presented by the display, the movement strategy setting unit receives a passenger'"'"'s operation of selecting one of the plurality of movement strategy candidates;

a degree of risk calculation unit for acquiring a degree of risk according to the movement strategy candidates, wherein the display presents the plurality of movement strategy candidates together with the degree of risk acquired by the degree of risk calculation unit; and

the movement trajectory generator generating the movement trajectory based on the movement strategies set by the movement strategy setting.

10. The movement trajectory generator according to claim 9, wherein movement strategy setting unit receives a passenger'"'"'s correction operation of the movement strategies.

11. The movement trajectory generator according to claim 10, further comprising degree of risk calculation unit for acquiring a degree of risk according to the movement strategies,

wherein the movement strategy setting unit changes an ease of correction of the movement strategies according to the degree of risk acquired by the degree of risk calculation unit.

12. The movement trajectory generator according to claim 9, further comprising a camera for detecting a passenger'"'"'s observation area,

wherein the display presents a setting information of the movement strategies in the observation area detected by the camera.
