PURPOSE: Vehicle-collision preventing device and method are provided to accurately expect a collision time by considering the maximum running speeds of own and leading vehicles. CONSTITUTION: A vehicle-collision preventing device comprises a speed detecting unit(100), an area detecting unit(200), a vehicle-type detecting unit(300) and a control unit(400). The speed detecting unit detects the speed and acceleration of own vehicle. The area detecting unit detects the relative distance between own and leading vehicles, and the speed and acceleration of the leading vehicle. The vehicle-type detecting unit detects the type of the leading vehicle. The control unit determines the maximum running speeds of own and leading vehicles based on the detected type and calculates the expected collision time between own and leading vehicle using data transferred from the speed and area detecting units, and maximum running speeds. |
