Abstract:
PURPOSE: A safety device and method of a vehicle for driving a narrow road are provided to ensure safe driving for a driver by determining the possibility or impossibility of a vehicle to pass through a narrow road in advance and to improve the visual capability of the driver when driving through the narrow road. CONSTITUTION: A safety device of a vehicle for driving a narrow road comprises a narrow road topography analyzing part (10), a pass possibility determining part (12), a vehicle driving state grasping part (14), a head-up display part (16), and a pair of LED lines. The narrow road topography analyzing part calculates the length and width of a narrow road on the basis of distance measurement sensors mounted on a GPS and the vehicle. The pass possibility determining part determines the pass of the vehicle on the basis of the calculation result. The vehicle driving state grasping part determines the safety of a driving state by calculating the central position, driving speed, and driving direction of the vehicle while passing through the narrow road. The head-up display part displays a narrow road display line for a route between the reference point of a head-up display and the calculated position of the narrow road. The pair of LED lines is mounted on a dashboard to inform a driver the leanness of the vehicle.

Abstract:
PURPOSE: An automatic recognizing method of a TPMS(Tire Pressure Monitoring System) is provided to minimize the wrong recognition error of recognizing the TPMS sensor signals of other vehicles by recognizing the tire of a vehicle on the basis of tire pressure and acceleration information transmitted from a TPMS sensor. CONSTITUTION: An automatic recognizing method of a tire pressure monitoring system comprises the following steps: measuring tire pressure and acceleration of a vehicle using a TPMS sensor; generating an integral message for including tire pressure and acceleration information, and a tire ID using the TPMS sensor; transmitting the integral message to an electronic control unit using the TPMS sensor; determining if the message received by the electronic control unit includes acceleration information; extracting the integral message with the highest RSSI value in the integral message; and registering the extracted ID.
