Abstract

A vehicle configured for determining an emotion state of a user, and adjusting a speed change of the vehicle that exerts an influence on the drive ability on the basis of the determined emotion state, and a method of controlling the same, may include a sensing unit configured to measure an acceleration of a vehicle and a bio-signal of a user; and a control unit connected to the sensing unit and configured to determine emotion state information indicating an emotion state of the user on the basis of the measured bio-signal when the measured acceleration is greater than or equal to a threshold acceleration, and on the basis of the emotion state information and correlation information indicating a relationship between the emotion state information and a drive ability factor related to a drive ability according to a speed change of the vehicle, update a setting value of the drive ability factor.

First claim

What is claimed is:

1. A vehicle comprising:
an acceleration sensor;
a bio-signal sensor;
a memory configured to store first correlation information indicating a relationship between bio-signals of a user and predetermined emotion factors, second correlation information indicating a relationship between the predetermined emotion factors and predetermined emotion state information, and third correlation information indicating a relationship between at least one drive ability factor related to a speed change and the predetermined emotion state information,
wherein the at least one drive ability factor includes at least one of acceleration, a change rate in the acceleration, a number of engine revolutions per minute, and an engine torque of the vehicle, and
wherein the third correlation information includes an increase or decrease degree of a setting value of each of the at least one drive ability factor; and
a controller configured to
measure an acceleration of the vehicle through the acceleration sensor,
identify a first emotion state information of the user from among the predetermined emotion state information, based on a bio-signal measured through the bio-signal sensor, the first correlation information and the second correlation information, when the measured acceleration is determined to be greater than or equal to a predetermined threshold acceleration, and
control a speed of the vehicle by updating a first setting value of a first drive ability factor, which corresponds to the first emotion state information, among the at least one drive ability factor based on the third correlation information and the first emotion state information,
wherein the predetermined emotion state information includes at least one type of a degree of positive to a speed responsiveness of the vehicle, a degree of positive to a speed linearity of the vehicle, and a degree of positive to a speed acceleration capability of the vehicle and a degree of negative to the speed change of the vehicle.

2. The vehicle of claim 1 , wherein the controller is configured to update the first setting value of the first drive ability factor such that the degree of positive to the emotion state information is increased or the degree of negative to the emotion state information is decreased.

3. The vehicle of claim 1 , wherein the controller, when the degree of positive to the speed responsiveness is determined to be equal to or less than a predetermined threshold value, is configured to determine the change rate in the acceleration or the number of engine revolutions per minute as the at least one drive ability factor corresponding to the degree of positive to the speed responsiveness, and to perform the updating such that the change rate of acceleration is increased according to a degree of increase or decrease corresponding thereto or the number of engine revolutions per minute is increased or decreased according to a degree of increase or decrease corresponding thereto.

4. The vehicle of claim 1 , wherein the controller, when the degree of positive to the speed acceleration capability is determined to be equal to or less than a predetermined threshold value, is configured to determine the change rate in the acceleration or the engine torque as the at least one drive ability factor corresponding to the degree of positive to the speed acceleration capability, and to perform the updating such that the change rate in the acceleration is increased according to a degree degree of increase or decrease corresponding thereto or the engine torque is increased or decreased according to a degree of increase or decrease corresponding thereto.

5. The vehicle of claim 1 , wherein the controller, when the degree of positive to the speed linearity is determined to be equal to or less than a predetermined threshold value or the degree of negative to the speed change is determined to be higher than or equal to a predetermined threshold value, is configured to determine the acceleration or the number of engine revolutions per minute as the at least one drive ability factor corresponding thereto, and to perform the updating such that the acceleration is decreased according to a degree of increase or decrease corresponding thereto or the number of engine revolutions per minute is decreased according to a degree of increase or decrease corresponding thereto.

6. The vehicle of claim 1 , wherein the controller, when the first setting value of the first drive ability factor is updated, is configured to control the bio-signal sensor to measure an additional bio-signal of the user, to identify a second emotion state information of the user from among the predetermined emotion state, based on the additional bio-signal and to adjust a degree of increase or decrease of the first setting value by comparing the second emotion state information with the first emotion state information.

7. A method of controlling a vehicle, the method comprising:
storing first correlation information indicating a relationship between bio-signals of a user and predetermined emotion factors, second correlation information indicating a relationship between the predetermined emotion factors and predetermined emotion state information, and third correlation information indicating a relationship between at least one drive ability factor related to a speed change and the predetermined emotion state information,
wherein the at least one drive ability factor includes at least one of acceleration, a change rate in the acceleration, a number of engine revolutions per minute, and an engine torque of the vehicle, and
wherein the third correlation information includes an increase or decrease degree of a setting value of each of the at least one drive ability factor,
measuring an acceleration of the vehicle;
identifying, by a controller, a first emotion state information of the user from among the predetermined emotion state information, based on a measured bio-signal, the first correlation information and the second correlation information, when the measured acceleration is determined to be greater than or equal to a predetermined threshold acceleration; and
controlling a speed of the vehicle by updating a first setting value of a first drive ability factor, which corresponds to the first emotion state information, among the at least one drive ability factor based on the third correlation information and the first emotion state information,
wherein the predetermined emotion state information includes at least one type of a degree of positive to a speed responsiveness of the vehicle, a degree of positive to a speed linearity of the vehicle, and a degree of positive to a speed acceleration capability of the vehicle and a degree of negative to the speed change of the vehicle.

8. The method of claim 7 , wherein the updating of the first setting value of the first drive ability factor includes performing updating such that the degree of positive to the emotion state information is increased or the degree of negative to the emotion state information is decreased.

9. The method of claim 7 , wherein the updating of the first drive ability factor includes:
when the degree of positive to the speed responsiveness is determined to be equal to or less than a predetermined threshold value, determining the change rate in the acceleration or the number of engine revolutions per minute as the at least one drive ability factor corresponding to the degree of positive to the speed responsiveness; and
performing updating such that the change rate of acceleration is increased according to a degree of increase or decrease corresponding thereto or the number of engine revolutions per minute is increased or decreased according to a degree of increase or de
