## Abstract

Provided is an apparatus for controlling a vehicle, the apparatus including: a communicator configured to receive a setting value signal related to at least one of a first setting value, a second setting value, or a third setting value that are set in advance from a user terminal, and transmit a signal to the user terminal; and a controller configured to control at least one of a travelling device, a braking device, or a steering device based on the at least one of the first setting value, the second setting value, or the third setting value that are set in advance.

## Claims

### Claim 1

An apparatus for controlling a vehicle, the apparatus comprising:
a communicator configured to receive a setting value signal related to at least one of a first setting value, a second setting value, or a third setting value that are set in advance from a user terminal, and transmit a signal to the user terminal; and
a controller configured to control at least one of a travelling device, a braking device, or a steering device based on the received setting value,
wherein the controller determines a speed of the vehicle, and controls the at least one of the travelling device, the braking device, or the steering device to absorb a shock applied to the vehicle based on the determined speed and the received setting value,
wherein the controller, when it is determined that the vehicle deviated from a preset posture, controls the at least one of the travelling device, the braking device, or the steering device based on the at least one of the first setting value, the second setting value, or the third setting value such that the vehicle maintains the preset posture,
wherein the controller determines whether the vehicle performs a sudden braking, and adjusts a hydraulic pressure of the braking device to apply a brake pressure to the braking device based on a result of the determination of performing sudden braking and the received setting value, and
wherein the controller determines, based on at least one of the first setting value, the second setting value, or the third setting value received from the user terminal, whether the vehicle is able to stop within a predetermined braking distance, and control at least one of the braking device or the steering device to minimize a braking distance of the vehicle in response to determining that the vehicle is not able to stop within the predetermined braking distance.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a determiner configured to determine user information, wherein the communicator receives the user information, and the controller controls the determiner to perform user authentication based on the user information.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the controller controls a sensitivity of the steering device.

### Claim 4 (depends on 1)

The apparatus of claim 1, further comprising an input configured to receive a signal for changing the at least one of the first setting value, the second setting value, or the third setting value from the user terminal, wherein the controller controls the at least one of the travelling device, the braking device, or the steering device based on the changing signal.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the controller determines whether to change steering of the vehicle, and controls the at least one of the travelling device, the steering device, or the braking device for the vehicle to be kept horizontal based on a result of the determination.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising a sensor configured to detect a state of a road surface on which the vehicle travels, wherein the controller controls the at least one of the travelling device, the steering device, or the braking device to prevent a slip of the vehicle based on a result of the detection.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the controller determines whether the braking device has generated a braking force sufficient to stop the vehicle within a preset sudden braking distance, and allows an additional pressure to be applied the braking device to minimize a braking distance of the vehicle based on a result of the determination.

### Claim 8

A method of controlling a vehicle, the method comprising:
receiving a setting value signal related to at least one of a first setting value, a second setting value, or a third setting value that are set in advance from a user terminal, and transmitting a signal to the user terminal; and
controlling at least one of a travelling device, a braking device, or a steering device based on the received setting value,
wherein the controlling includes determining a speed of the vehicle, and controlling the at least one of the travelling device, the braking device, or the steering device to absorb a shock applied to the vehicle based on the determined speed and the received setting value,
wherein the controlling includes, when it is determined that the vehicle deviated from a preset posture, controlling the at least one of the travelling device, the braking device, or the steering device based on the at least one of the first setting value, the second setting value, or the third setting value such that the vehicle maintains the preset posture,
wherein the controlling includes determining whether the vehicle performs a sudden braking, and adjusting a hydraulic pressure of the braking device to apply a brake pressure to the braking device based on a result of the determination of performing sudden braking and the received setting value, and
wherein the controlling includes determining, based on at least one of the first setting value, the second setting value, or the third setting value received from the user terminal, whether the vehicle is able to stop within a predetermined braking distance, and controlling at least one of the braking device or the steering device to minimize a braking distance of the vehicle in response to determining that the vehicle is not able to stop within the predetermined braking distance.

### Claim 9 (depends on 8)

The method of claim 8, further comprising determining user information, wherein the receiving includes receiving the user information, and the controlling includes performing user authentication based on the user information.

### Claim 10 (depends on 8)

The method of claim 8, wherein the controlling includes controlling a sensitivity of the steering device.

### Claim 11 (depends on 8)

The method of claim 8, further comprising receiving a signal for changing the at least one of the first setting value, the second setting value, or the third setting value from the user terminal, wherein the controlling includes controlling the at least one of the travelling device, the braking device, or the steering device based on the changing signal.

### Claim 12 (depends on 8)

The method of claim 8, wherein the controlling includes determining whether to change steering of the vehicle, and controlling the at least one of the travelling device, the steering device, or the braking device for the vehicle to be kept horizontal based on a result of the determination.

### Claim 13 (depends on 8)

The method of claim 8, further comprising detecting a state of a road surface on which the vehicle travels, wherein the controlling includes controlling the at least one of the travelling device, the steering device, or the braking device to prevent a slip of the vehicle based on a result of the detection.

### Claim 14 (depends on 8)

The method of claim 8, wherein the controlling includes determining whether the braking device has generated a braking force sufficient to stop the vehicle within a preset sudden braking distance, and allowing an additional pressure to be applied the braking device to minimize a braking distance of the vehicle based on a result of the determination.
