## Abstract

The present disclosure relates to a device for assisting a safe exit from a vehicle, a system having the same, and a method thereof. The device for assisting a safe exit from a vehicle may include a processor for determining a surrounding situation around the vehicle and an intent of the passenger to exit from the vehicle, and performing a step-by-step notification based on the determination, and storage for receiving, from the processor, and storing information about the surrounding situation and a determination result of the intent of the passenger to exit from the vehicle.

## Claims

### Claim 1

A device for assisting a safe exit from a vehicle, the device comprising:
a processor configured for determining a surrounding situation around the vehicle and an intent of a passenger to exit from the vehicle, and performing a step-by-step notification based on the determination; and
storage configured for receiving, from the processor, and storing information about the surrounding situation and a determination result of the intent of the passenger to exit from the vehicle,
wherein the processor detects an external object approaching the vehicle using a radar sensor,
the radar sensor calculates a distance to an external object based on a frequency difference between a transmitted signal and a received signal,
the received signal is a radar wave to be reflected by the external object, and
when the external object enters a set sensing range of the radar sensor, the processor calculates a coordinate of the external object using differences of distance values between the external object and receivers based on signals received by the receivers.

### Claim 2 (depends on 1)

The device of claim 1, wherein the processor performs a primary notification when the external object approaching from a rear lateral side of the vehicle is detected.

### Claim 3 (depends on 2)

The device of claim 2, wherein the processor displays a notification message or a notification image on a display or turns on a door lamp for the primary notification.

### Claim 4 (depends on 2)

The device of claim 2, wherein the processor performs the primary notification when the external object approaches a rear-side of a seat occupied by the passenger is detected.

### Claim 5 (depends on 2)

The device of claim 2, wherein the processor determines that the passenger has the intent to exit from the vehicle when at least one of following cases is detected while a seat belt is unfastened:
a case when the passenger moves toward a position which the external object is drawing closer to;
a case when a hand of the passenger touches a door handle; and
a case when the hand of the passenger is approaching the door handle.

### Claim 6 (depends on 5)

The device of claim 5, wherein the processor performs a secondary notification when it is determined that the passenger has the intent to exit from the vehicle.

### Claim 7 (depends on 6)

The device of claim 6, wherein, in the performing of the secondary notification, the processor performs a door lock control together.

### Claim 8 (depends on 6)

The device of claim 6, wherein the processor performs at least one of a seat vibration, a door handle vibration, a sound warning, and a rendering of a door lamp in different colors for the secondary notification.

### Claim 9

A vehicle system comprising:
a device for assisting a safe exit from a vehicle, wherein the device is configured for determining a surrounding situation around the vehicle and an intent of a passenger to exit from the vehicle, and performing a step-by-step notification based on the determination; and
a sensing module for sensing the surrounding situation and a movement of the passenger,
wherein the device detects an external object approaching the vehicle using a radar sensor,
the radar sensor calculates a distance to the external object based on a frequency difference between a transmitted signal and a received signal,
the received signal is a radar wave to be reflected by the external object, and
when the external object enters a set sensing range of the radar sensor, the device calculates a coordinate of the external object using differences of distance values between the external object and receivers based on signals received by the receivers.

### Claim 10 (depends on 9)

The vehicle system of claim 9, wherein the sensing module includes:
an interior radar sensor for sensing the movement of the passenger in the vehicle;
a seat belt sensor for detecting whether a seat belt of the vehicle is fastened; and
a rear-side radar sensor for sensing a movement of the external object from a rear lateral side of the vehicle or a camera for capturing an object near a rear and lateral face of the vehicle.

### Claim 11 (depends on 9)

The vehicle system of claim 9, wherein the device performs:
a primary notification when the external object approaching from a rear lateral side of the vehicle is detected; and
a secondary notification when the passenger has the intent to exit from the vehicle.

### Claim 12 (depends on 11)

The vehicle system of claim 11, wherein the device displays a notification message or notification image on a display, or turns-on a door lamp for the primary notification.

### Claim 13 (depends on 11)

The vehicle system of claim 11, wherein the device determines that the passenger has the intent to exit from the vehicle when at least one of following cases is detected while a seat belt is unfastened:
a case when the passenger moves toward a position which the external object is drawing closer to;
a case when a hand of the passenger touches a door handle; and
a case when the hand of the passenger is approaching the door handle.

### Claim 14 (depends on 11)

The vehicle system of claim 11, wherein the device performs a secondary notification when it is determined that the passenger has the intent to exit from the vehicle.

### Claim 15 (depends on 14)

The vehicle system of claim 14, wherein the device performs at least one of a seat vibration, a door handle vibration, a sound warning, and a rendering of a door lamp in a different color for the secondary notification.

### Claim 16

A method for assisting a safe exit from a vehicle, the method comprising:
sensing, by a sensing module, a surrounding situation around the vehicle;
determining, by a processor, an intent of a passenger to exit from the vehicle; and
performing, by the processor, a step-by-step notification based on the sensed surrounding situation and the determined intent of the passenger to exit from the vehicle,
wherein the sensing module detects an external object approaching the vehicle using a radar sensor,
the radar sensor calculates a distance to the external object based on a frequency difference between a transmitted signal and a received signal,
the received signal is a radar wave to be reflected by the external object, and
when the external object enters a set sensing rage of the radar sensor, the processor calculates a coordinate of the external object using differences of distance values between the external object and receivers based on signals received by the receivers.

### Claim 17 (depends on 16)

The method of claim 16, wherein the sensing of the surrounding situation around the vehicle includes sensing whether the external object approaching from a rear lateral side of the vehicle exists.
