  • the control unit (120) can determine whether a surrounding vehicle is within the specific range (A) based on the location information of the surrounding vehicle.

  • the size of the specific range may vary depending on the vehicle's driving mode or vehicle speed. Specifically, the larger the vehicle's driving mode is, the more rapid the vehicle movement is, and the faster the vehicle's speed is, the larger the specific range may be. This is because the more rapidly or quickly the vehicle moves, the wider the range of surrounding objects must be recognized and provided to the driver.

  • Figure 10 is a drawing for explaining a method for determining the driving direction of surrounding vehicles.
  • the control unit (120) can determine the driving direction of the surrounding vehicles. Since vehicles move one-dimensionally on the road, the driving direction of the surrounding vehicles may include the same direction as the driving direction of the vehicle (1) and the opposite direction to the driving direction of the vehicle (1). For example, the driving direction of the second surrounding vehicle (3) moving in the same direction as the vehicle (1) on a four-lane road may be the same as the driving direction of the vehicle (1). For another example, the driving direction of the first surrounding vehicle (1) moving in the opposite lane on a four-lane road may be the opposite to the driving direction of the vehicle (1).

  • Stop no direction
  • the driving direction of the surrounding vehicle may be Stop (no direction).
  • the control unit (120) can determine the driving direction of the surrounding vehicle based on the change in distance from the surrounding vehicle and the speed of the vehicle (1).
  • control unit (120) can continuously track the distance to surrounding vehicles and obtain changes in the distance to surrounding vehicles.
  • control unit (120) can determine the driving direction of surrounding vehicles based on the changes in the distance and the speed of the vehicle (1).
  • control unit (120) may determine that the distance between the vehicle (1) and the fourth surrounding vehicle is 200 meters at a first point in time, and that the distance between the vehicle (1) and the fourth surrounding vehicle is 190 meters at a second point in time (1 second after the first point in time). If the speed of the vehicle (1) is 10 meters per second, this means that the second surrounding vehicle (3) is not moving. Therefore, the control unit (120) may determine that the driving direction of the second surrounding vehicle (3) is stop (no direction).
  • control unit (120) may determine that the distance between the vehicle (1) and the first surrounding vehicle (2) is 200 meters at a first point in time, and that the distance between the vehicle (1) and the first surrounding vehicle (2) is 180 meters at a second point in time (1 second after the first point in time). If the speed of the vehicle (1) is 10 meters per second, this means that the first surrounding vehicle (2) is moving in the opposite direction at a speed of 10 meters per second. Therefore, the control unit (120) may determine that the driving direction of the first surrounding vehicle (2) is opposite to the driving direction of the vehicle (1).
  • the control unit (120) can control the ambient light to indicate that the driving direction of the first surrounding vehicle (2) is opposite to the driving direction of the vehicle (1).
  • the control unit (120) can control the ambient light (140) to indicate that the driving direction of the first surrounding vehicle (2) is opposite by at least one of the size or emission color of the display area of the first surrounding vehicle (2).

  • the first surrounding vehicle (2) and the second surrounding vehicle (3) are spaced apart from the vehicle (1) by the same distance. Nevertheless, according to the present invention, it is possible to provide the fact that the first surrounding vehicle (2) is a vehicle traveling in the opposite direction to the vehicle (1) and the second surrounding vehicle (3) is a vehicle traveling in the same direction as the vehicle (1). In addition, according to the present invention, it is possible to provide the driver with the fact that another surrounding vehicle is stopped. Accordingly, the driver can clearly recognize the surrounding situation and prepare for any possible danger in advance.

  • control unit (12) can obtain information about the lane in which the first surrounding vehicle (2) is driving.
  • a lane recognition technology already known can be used.
  • the first surrounding vehicle (2) is driving in the opposite lane, the first surrounding vehicle (2) is driving normally. On the other hand, if the first surrounding vehicle (2) is driving in the same lane as vehicle (1), the first surrounding vehicle (2) is currently driving in reverse and requires a warning.
  • the control unit (120) can control the ambient light so that a warning is output.
  • the control unit (120) can increase the size of the display area, display a color indicating a warning on the entire ambient light, perform a blink on or off on all or part of the ambient light, or sequentially illuminate multiple areas of the ambient light.

  • the control unit (120) can control the second display area corresponding to the second surrounding vehicle to emit light.
  • the first specific range may be larger than the second specific range. That is, since the first surrounding vehicle opposite to the driving direction of the vehicle may pose a greater threat to the safety of the vehicle, the device (100) can provide information on the first surrounding vehicle to the driver from a further distance.
  • information about surrounding vehicles can be intuitively provided to the driver and safe driving can be induced.
  • information about surrounding vehicles can be provided through ambient light to enhance the thrill and fun of driving (for example, displaying in real time through ambient light the situation in which one's own vehicle is overtaking a surrounding vehicle) and thus increase the emotional satisfaction of the driver.
