  • Publication number: 20200225343
    Abstract: The present disclosure provides a vehicle radar system capable of detecting the appearance of dangerous objects with higher reliability. Further, the present disclosure provides a vehicle radar system that can provide both safety and convenience of a driver by combining a radar sensor with a black box or a navigation device which is almost a necessity for vehicles. Accordingly, the present disclosure provides a vehicle radar system in which a radar sensor is installed in a vehicle to calculate the speed of the host vehicle during driving, detect an object appearing ahead of the vehicle, calculate a relative speed between the host vehicle and the object, link the radar sensor to a user device, such as a smartphone of the driver, or a navigation device through near-field communication and issue a warning through the user device or the navigation device depending on the distance to the appearing object.
