Abstract

A system for controlling a smart mobility by risk level includes: an information collection unit to collect position and speed information of the smart mobility and camera sensing information including a front traffic sign or object; a front detection unit to detect a front obstacle or inclination using the camera sensing information and to output a detection result; a control unit to change a warning to a user and/or a method of controlling the smart mobility by risk level based on the information collected by the information collection unit and the detection result; and a warning unit to warn the user by changing a method by risk level under the control of the control unit.

First claim

What is claimed is:

1. A system for controlling a smart mobility by risk level, the system comprising:
an information collection unit configured to collect position and speed information of the smart mobility and camera sensing information including a front traffic sign or object;
a front detection unit configured to detect a front obstacle or inclination using the camera sensing information and to output a detection result;
a control unit configured to change a warning to a user and/or a method of controlling the smart mobility by risk level based on the information collected by the information collection unit and the detection result, such that the control unit is configured to change the warning to the user and/or the method of controlling the smart mobility by risk level in both a situation in which the smart mobility has entered an accident risk area and a situation in which the front obstacle has been detected; and
a warning unit configured to warn the user by changing a method by risk level under the control of the control unit,
wherein the control unit is configured to limit a maximum speed of the smart mobility based on the information collected by the information collection unit when the information collection unit determines that the smart mobility has entered the accident risk area, and
wherein the control unit is configured to operate the warning unit to provide an auditory feedback to the user at a first risk level, to operate the warning unit to provide a tactile feedback to the user at a second risk level, and to actively intervene in speed/braking control of the smart mobility at a third risk level.

2. The system of claim 1 , further comprising a voice guidance unit configured to provide a voice guidance to the user about why an active control is performed under the control of the control unit when the control unit actively intervenes in speed/braking control of the smart mobility.

3. The system of claim 1 , wherein the information collection unit comprises:
a GPS module configured to collect the position information of the smart mobility in real time to calculate a movement direction and a movement speed of the smart mobility using the position information; and
a camera sensor configured to collect the camera sensing information and to transmit the camera sensing information to the GPS module and the front detection unit.

4. The system of claim 3 , wherein the front detection unit comprises:
an obstacle detection unit configured to analyze the information collected by the GPS module and the camera sensing information to recognize whether the front obstacle is present and a type of the obstacle; and
an inclination detection unit configured to calculate a gradient of a slope using the camera sensing information transmitted by the camera sensor, and to determine the slope as having a steep inclination when the calculated gradient exceeds a set gradient (angle) and to determine the slope as having a gradual inclination when the calculated gradient does not exceed the set gradient.

5. A method of controlling a smart mobility by risk level, the method comprising:
collecting surrounding information according to current position information of the smart mobility using a GPS;
determining whether the smart mobility has entered an accident risk area;
collecting camera sensing information including a front traffic sign or object through a camera sensor;
checking whether there is a front obstacle based on the camera sensing information;
changing a warning to a user and/or a method of controlling the smart mobility by risk level based on the surrounding information and the camera sensing information, such that the warning to the user and/or the method of controlling the smart mobility by risk level is changed in both a situation in which the smart mobility has entered an accident risk area and a situation in which the front obstacle has been detected; and
performing warning/control/voice guidance by risk level to the user,
wherein the controlling includes limiting a maximum speed of the smart mobility when it is determined that the smart mobility has entered the accident risk area, and
wherein changing the warning includes providing an auditory feedback to the user at a first risk level, providing a tactile feedback to the user at a second risk level, and actively intervening in speed/braking control of the smart mobility at a third risk level.
