PURPOSE: A junction box for a vehicle is provided to prevent the malfunction of a buzzer due to operation noise of a horn or an electronic parking brake. CONSTITUTION: A junction box for a vehicle comprises sensors(100,200), a main MCU(Micro Control Unit)(10), and a sub MCU. The sensors determine whether a vehicle approaches an obstacle within the reference distance and, if so, output an alarm control signal. The main MCU communicates with an external communication device. The sub MCU receives an alarm control signal from the sensors and, when a request is inputted from the main MCU to the sub MCU, outputs a PAS(Parking Aid System) detection signal corresponding to the alarm control signal to the main MCU.
