A system and method enhance vehicle safety by identifying dangerous objects using a precise map database. A sensor acquires an object's current motion information, and a navigator obtains vehicle location information. A controller processes this data, converting the object's motion into first absolute coordinates on a precise map. These first absolute coordinates are compared with an expected motion value, which is represented as second absolute coordinates on the precise map and derived from statistical historical driving data of other vehicles stored in the precise map database. If a difference value between these two sets of absolute coordinates exceeds a predetermined threshold, the object is identified as dangerous. Information about the identified dangerous object, along with the ego-vehicle, is then visually presented to the driver on the precise map via a human-machine interface (HMI), thereby improving situational awareness.

Vehicle and control method thereof

A method and system for diagnosing a state of fuel cell are provided. The system includes a signal measurement unit that has a high pass filter with a predetermined cut-off frequency and a voltage measurement circuit, and that measures a first AC voltage to measure the fuel cell state diagnosis signal and a noise measurement unit including a band pass filter that has a predetermined pass band and a voltage measurement circuit, and that measures a second AC voltage to measure the fuel cell state diagnosis noise. A controller calculates a signal to noise ratio (SNR) of fuel cell state diagnosis data based on the first and second AC voltages, determines the corresponding fuel cell state diagnosis data to be reliable when the SNR value is greater than a predetermined reference value, and applies the fuel cell state diagnosis data to a control of a fuel cell vehicle.
