Abstract

Claims (46)

1 . A driving support device comprising:

a sensor configured to acquire data of a space inside a vehicle and data of a space outside the vehicle; and

a controller,

wherein the controller is configured to:

determine whether the vehicle is in an abnormal state based on the data acquired by the sensor;

upon determining that the vehicle is in the abnormal state, output a first message indicating that the vehicle is in the abnormal state to a user on the vehicle;

acquire a first answer from the user to the first message via an input device;

propose use of a support function for supporting the user based on the first answer from the user to the first message; and

acquire a second answer from the user to the proposed use of the support function via the input device;

wherein the first message includes a message for confirming the responsibility to the user, a message concerning a state of the vehicle, a message for confirming a feeling of the user, or a message for confirming safety of the user; and

wherein, upon determining that the first answer from the user to the first message for confirming the responsibility indicates that the user does not admit the responsibility, the controller is configured to output a second message indicating that the user has the responsibility.

2 . The driving support device according to claim 1 , wherein the vehicle being in the abnormal state means a situation where there is a possibility of a collision or an accident of the vehicle.

3 . The driving support device according to claim 1 , wherein the first answer from the user relates to a feeling indicating anxiety or danger about the abnormal state of the vehicle.

4 . The driving support device according to claim 1 , wherein, upon determining that the first answer from the user to the message indicates anxiety or danger, the controller is configured to propose use of the support function for supporting the user.

5 . The driving support device according to claim 4 , wherein the controller is configured to:

estimate a cause of occurrence of the abnormal state based on the data acquired by the sensor;

upon estimating that the cause arises from driving by the user, output a message for confirming responsibility to the user; and

upon determining that the first answer from the user to the message indicates that the user admits the responsibility, propose use of the support function for supporting the user.

6 . The driving support device according to claim 1 , wherein the message for confirming the responsibility to the user is a message for confirming to the user whether something has happened in the vehicle or in a periphery of the vehicle.

7 . A driving support method comprising:

acquiring data of a space inside a vehicle and data of a space outside the vehicle;

determining whether the vehicle is in an abnormal state based on the acquired data;

upon determining that the vehicle is in the abnormal state, outputting a first message indicating that the vehicle is in the abnormal state to a user on the vehicle;

acquiring a first answer from the user to the first message via an input device;

proposing use of a support function for supporting the user based on the first answer from the user to the first message; and

acquiring a second answer from the user to the proposed use of the support function via the input device;

wherein the first message includes a message for confirming the responsibility to the user, a message concerning a state of the vehicle, a message for confirming a feeling of the user, or a message for confirming safety of the user; and

wherein, upon determining that the first answer from the user to the first message for confirming the responsibility indicates that the user does not admit the responsibility, the controller is configured to output a second message indicating that the user has the responsibility.

8 . A driving support device comprising:

a sensor configured to acquire data of a space inside a vehicle and data of a space outside the vehicle; and

a controller,

wherein the controller is configured to:

determine whether the vehicle is in an abnormal state based on the data acquired by the sensor;

upon determining that the vehicle is in the abnormal state, output a message indicating that the vehicle is in the abnormal state to a user on the vehicle;

acquire an answer from the user to the message via an input device; and

propose use of a support function for supporting the user based on the answer from the user to the message,

wherein the message includes a message for confirming the responsibility to the user, a message concerning a state of the vehicle, a message for confirming a feeling of the user, or a message for confirming safety of the user, and

wherein, upon determining that an answer from the user to the message for confirming the responsibility indicates that the user does not admit the responsibility, the controller is configured to output a message indicating that the user has the responsibility.

9 . A driving support method comprising:

acquiring data of a space inside a vehicle and data of a space outside the vehicle;

determining whether the vehicle is in an abnormal state based on the acquired data;

upon determining that the vehicle is in the abnormal state, outputting a message indicating that the vehicle is in the abnormal state to a user on the vehicle;

acquiring an answer from the user to the message via an input device;

proposing use of a support function for supporting the user based on the answer from the user to the message;

wherein the message includes a message for confirming the responsibility to the user, a message concerning a state of the vehicle, a message for confirming a feeling of the user, or a message for confirming safety of the user; and

upon determining that an answer from the user to the message for confirming the responsibility indicates that the user does not admit the responsibility, outputting a message indicating that the user has the responsibility.
