Problems solved by technology
[0004] However, the existing adaptive cut-off line system does not take into account the relative speed of the other vehicle and the response speed of the system. Therefore, the optical path is adaptively run only when the vehicle is in a stationary state, and the optical path changes at a specific interval. Therefore, there is a problem of not being able to maintain a wider field of vision for the driver of a vehicle equipped with an adaptive cut-off system

The present invention provides an adaptive cut-off line system comprising: a relative speed calculating part for calculating the relative speed of a counter vehicle; and an inter-vehicle distance calculating part for calculating the distance between vehicles after system response time according to the relative speed. According to the present invention, a beam can be accurately irradiated according to the relative speed of a preceding vehicle and a counter vehicle in consideration of the response speed of the adaptive cut-off line system. Therefore, the adaptive cut-off line system prevents a driver in a counter vehicle from being dazzled and improves visibility of a driver.

Description
technical field [0001] The present invention relates to an adaptive cut-off line system and a control method thereof, in particular to an adaptive light-and-dark system capable of performing accurate beam irradiation according to the relative speed of an oncoming vehicle or a vehicle in front in consideration of the response speed of the adaptive light-and-dark cut-off system Cutoff line system and control method thereof. Background technique [0002] The adaptive cut-off line (aCOL, Adaptive Cut-OffLine) system is a device that recognizes other vehicles and automatically adjusts the headlights of the vehicle. [0003] The adaptive cut-off line system operates the high beam when there is no oncoming vehicle, and when the camera detects an oncoming vehicle, it drives the shielding driver at a specific interval according to the distance between vehicles, thus, without causing oncoming vehicles A system that ensures the driver's visibility by irradiating the maximum high beam ...
