Abstract

Disclosed herein a vehicle includes a display; a sound device; a vibrator; an occupant detector configured to detect an occupant to output occupant information; an obstacle detector configured to detect an obstacle to output obstacle information; a braking system that generates a braking force; and a controller configured to set braking distance information based on the occupant information, control operation of at least one of the display, the sound device, and the vibrator based on the set braking distance information and the obstacle information, and control the braking system in response to operation control information of the at least one of the display, the sound device and the vibrator.

First claim

What is claimed is:

1. A vehicle, comprising:
a display;
a sound device;
a vibrator;
an occupant detector configured to detect an occupant to output occupant information including at least one of the number of occupants and a total weight of occupants;
an obstacle detector configured to detect an obstacle to output obstacle information;
a braking system that generates a braking force; and
a controller configured to:
set braking distance information based on the at least one of the number of occupants and the total weight of occupants, control operation of at least one of the display, the sound device, and the vibrator based on the set braking distance information and the obstacle information, and control the braking system in response to operation control information of the at least one of the display, the sound device and the vibrator.

2. The vehicle of claim 1 , wherein the braking system is configured to perform a prefill, a pre-braking, and an emergency braking.

3. The vehicle of claim 2 , wherein the controller is configured to:
control the operation of the sound device when performing control for the prefill, and
control the operation of the sound device, the display, and the vibrator when performing control for the pre-braking and the emergency braking,
wherein a volume of sound output from the sound device while controlling the emergency braking is greater than that of sound output from the sound device while controlling the pre-braking; and
an intensity of vibration generated by the vibrator while controlling the emergency braking is greater than that of vibration generated by the vibrator while controlling the pre-braking.

4. The vehicle of claim 1 , further comprising a storage for storing a braking distance corresponding to the number of occupants,
wherein when setting the braking distance based on the at least one of the number of occupants and the total weight of occupants,
the controller is configured to:
set the braking distance to a predetermined braking distance in response to determining that the number of occupants is a predetermined number based on the occupant information,
set the braking distance corresponding to the number of occupants based on information stored in the storage in response to determining that the number of occupants exceeds the predetermined number, and
the set braking distance is longer than the predetermined braking distance.

5. The vehicle of claim 4 , wherein the predetermined braking distance comprises a first braking distance for controlling the prefill, a second braking distance for controlling the pre-braking, and a third braking distance for controlling the emergency braking.

6. The vehicle of claim 5 , wherein the controller is configured to:
obtain relative distance information with the obstacle based on the obstacle information, and control the prefill, the pre-braking, and the emergency braking based on the obtained relative distance information with the obstacle and the first, second and third braking distances.

7. The vehicle of claim 6 , wherein the controller is configured to:
determine a warning time of a first stage in response to a control time of the prefill, determine a warning time of a second stage in response to a control time of the pre-braking, and determine a warning time of a third stage in response to a control time of the emergency braking.

8. The vehicle of claim 1 , wherein the occupant detector is provided on a plurality of seat belts, respectively, and detects attachment/detachment of each belt to output attachment/detachment information.

9. The vehicle of claim 1 , wherein the occupant detector is provided on a plurality of seats, respectively, and detects a weight applied to each seat to output weight information detected.

10. A vehicle, comprising:
an occupant detector configured to detect an occupant to output occupant information;
an obstacle detector configured to detect an obstacle to output obstacle information;
a braking system that performs a prefill, a pre-braking and an emergency braking;
a storage configured to store information on a first braking distance for controlling the prefill, a second braking distance for controlling the pre-braking, and a third braking distance for controlling the emergency braking, and store information on an increasing distance of the first braking distance, an increasing distance of the second braking distance, and an increasing distance of the third braking distance, per the number of occupants; and
a controller configured to:
control the braking system based on the information on the first, second and third braking distances and the obstacle information in response to determining that the number of occupants is a predetermined number based on the occupant information, and
identify the information on the increasing distances of the first, second and third braking distances corresponding to the number of occupants in response to determining that the number of occupants exceeds the predetermined number and control the braking system based on the information on the increasing distances of the first, second and third braking distances and the obstacle information.

11. The vehicle of claim 10 , wherein the controller is configured to:
determine a warning time of a first stage in response to a control time of the prefill, determine a warning time of a second stage in response to a control time of the pre-braking, and determine a warning time of a third stage in response to a control time of the emergency braking.

12. The vehicle of claim 11 , further comprising a display, a sound device, and a vibrator,
wherein the controller is configured to control operation of the sound device in response to determining that it is the warning time of the first stage, and control operation of the sound device, the display, and the vibrator in response to determining that it is the warning time of the second and third stages.

13. The vehicle of claim 12 , wherein
a volume of sound output from the sound device when controlling the emergency braking, by the controller, is greater than that of sound output from the sound device when controlling the pre-braking, and
an intensity of vibration generated by the vibrator when controlling the emergency braking, by the controller, is greater than that of vibration generated by the vibrator when controlling the pre-braking.

14. An advanced driver assistance system, comprising:
a camera for obtaining an image of a road and an image of an occupant; and
a controller including a processor for processing the image of the road obtained by the camera,
wherein the controller is configured to:
obtain occupant information from the image obtained by the camera,
control a prefill, a pre-braking, and an emergency braking based on predetermined first, second, and third braking distance information in response to determining that the number of occupants is a predetermined number based on the obtained occupant information, and
control the prefill, the pre-braking and the emergency braking based on information on an increasing distance of the first, second, and third braking distances corresponding to the number of occupants in response to determining that the number of occupants exceeds the predetermined number.

15. The advanced driver assistance system of claim 14 , wherein the controller is configured to:
