Abstract

A movement trajectory generator that generates a movement trajectory of a vehicle is provided, which includes traveling environment recognition means for recognizing a traveling environment, movement strategy generation means 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 for presenting a passenger setting information of the movement strategies, setting means 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 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 an automatic driving vehicle, the movement trajectory generator comprising an electronic control unit and a display having a touch screen, wherein:

the electronic control unit recognizes a traveling environment;

the electronic control unit generates a plurality of movement strategy candidates for positioning in a road area according to the traveling environment;

the display displays the plurality of movement strategy candidates;

the electronic control unit receives a touch operation signal from the display in response to a touch operation of the touch screen of the display, wherein the touch operation signal is indicative of a selection of a selected movement strategy candidate of the plurality of movement strategy candidates; and

the electronic control unit generates the movement trajectory of the automatic driving vehicle based on the selected movement strategy candidate.

2. The movement trajectory generator according to claim 1, wherein the electronic control unit receives a second touch operation signal from the display in response to a second touch operation of the touch screen of the display, wherein the second touch operation signal is indicative of a passenger'"'"'s correction operation of the movement strategies.

3. The movement trajectory generator according to claim 1, wherein the electronic control unit detects a passenger'"'"'s observation area based on image data received from a camera,

wherein the display displays the plurality of movement strategy candidates in the observation area.

4. The movement trajectory generator according to claim 1, wherein the display displays a factor for selecting the selected movement strategy candidate.

5. The movement trajectory generator according to claim 1, wherein the electronic control unit recognizes a state of surrounding objects, and

the display displays the state of the surrounding objects.

6. A computer-implemented method for generating a movement trajectory of a vehicle, comprising:

recognizing, by a computing device, at least one object based on at least one of image data received from a camera and a radar signal received from a radar;

determining a traveling scene based on the recognized at least one object;

setting at least one movement strategy based on the determined traveling scene;

generating a first movement trajectory of the vehicle based on the set at least one movement strategy;

setting a plurality of movement strategy candidates;

displaying the plurality of movement strategy candidates on a display;

receiving input indicative of a selection of a selected movement strategy candidate of the plurality of movement strategy candidates; and

generating a second movement trajectory of the vehicle based on the selected movement strategy candidate.

7. The method of claim 6, further comprising recognizing at least one attribute of the at least one object or recognizing a state of the at least one object.

8. The method of claim 6, further comprising determining the traveling scene based on a position relationship between the at least one object and the vehicle.

9. The method of claim 6, further comprising searching a movement strategy database with the traveling scene as a key, and extracting at least one movement strategy that corresponds to the traveling scene.

10. The method of claim 6, further comprising displaying at least one character or icon corresponding to the at least one object.

11. The method of claim 6, wherein the input is a touch operation signal from the display in response to a touch operation of the touch screen of the display, wherein the touch operation signal is indicative of a selection of the selected movement strategy candidate.
