Safe exit warning apparatus and method for occupant
View Patent ↗A safe exit warning apparatus and method for an occupant may include a first sensor that detects position of the occupant in the vehicle, a second sensor that detects an approaching object from the vehicle's blind spot, a warning device that warns the occupant about collision with the object, and a controller that determines the occupant's intent to get out of the vehicle by monitoring the position of the occupant in the vehicle when the vehicle stops and that controls the warning device to warn the occupant about the collision with the approaching object.
1. A safe exit warning apparatus of an occupant, the safe exit warning apparatus comprising:
a first sensor configured to detect a position of the occupant in a vehicle;
a second sensor configured to detect an approaching object from a blind spot of the vehicle;
a warning device configured to warn the occupant about collision of the occupant with the approaching object; and
a controller connected to the warning device and configured to determine the occupant's intent to get out of the vehicle by monitoring the position of the occupant in the vehicle when the vehicle stops and to control the warning device to warn the occupant about the collision with the approaching object,
wherein the controller is configured to determine the occupant's intent to get out of the vehicle when it is detected by the first sensor that body of the occupant faces a door of the vehicle,
wherein the controller is configured to output a warning sound through a speaker provided in it is detected by the first sensors that rear door of the vehicle or to apply vibration to a seat corresponding to the position of the occupant, when determining that the occupant will get out of the vehicle through the rear door of the vehicle, and
wherein the controller is configured to stop an output of the warning sound through the speaker provided in the rear door and to output the warning sound through a speaker provided in a front door of the vehicle, upon determining that the approaching object deviates from a detection area of the second sensor.
2. The safe exit warning apparatus of claim 1 , wherein the controller is further configured to increase an output of the warning sound with a decrease in separation distance between the blind spot and the approaching object.
3. The safe exit warning apparatus of claim 1 , wherein the controller is further configured to set volume amount of the speaker provided in the front door to be a same as volume amount which was set when the speaker provided in the rear door was operated.
4. The safe exit warning apparatus of claim 1 , further including:
a third sensor mounted on a front side of the vehicle and configured to detect the approaching object,
wherein the controller is configured to stop the output of the warning sound through the speaker provided in the front door when the approaching object is detected by the third sensor.
5. A safe exit warning method for an occupant, the safe exit warning method comprising:
detecting, by a first sensor, a position of the occupant in a vehicle;
detecting, by a second sensor, an approaching object from a blind spot of the vehicle;
determining, by a controller, the occupant's intent to get out of the vehicle, according to the position of the occupant in the vehicle when the vehicle stops; and
warning, by a warning device connected to the controller, the occupant about collision of the occupant with the approaching object,
wherein the determining, by the controller, the occupant's intent to get out of the vehicle includes determining the occupant's intent to get out of the vehicle when it is detected by the first sensor that body of the occupant faces a door of the vehicle, and
wherein the warning, by the warning device connected to the controller, the occupant about the collision of the occupant with the approaching object includes:
outputting a warning sound through a speaker provided in a rear door of the vehicle or applying vibration to it is detected by the first sensors that seat corresponding to the position of the occupant, when the controller determines that the occupant will get out of the vehicle through the rear door of the vehicle; and
stopping the output of the warning sound through the speaker provided in the rear door and outputting the warning sound through a speaker provided in a front door of the vehicle, upon determining that the approaching object deviates from a detection area of the second sensor.
6. The safe exit warning method of claim 5 , wherein the warning, by the warning device connected to the controller, the occupant about the collision of the occupant with the approaching object further includes:
increasing an output of the warning sound with a decrease in separation distance between the blind spot and the approaching object.
7. The safe exit warning method of claim 5 , wherein the warning, by the warning device connected to the controller, the occupant about the collision of the occupant with the approaching object further includes:
setting volume amount of the speaker provided in the front door to be a same as volume amount which was set when the speaker provided in the rear door was operated.
8. The safe exit warning method of claim 5 , wherein the warning, by the warning device connected to the controller, the occupant about the collision of the occupant with the approaching object further includes:
stopping the output of the warning sound through the speaker provided in the front door when the approaching object is detected by a third sensor mounted on a front side of the vehicle.
