PURPOSE: A car-crash preventing device is provided to enable an emergency lamp to be automatically lit without the operation of a driver if a tire pressure sensor senses the damage of the tire. CONSTITUTION: A car-crash preventing device comprises a tire pressure sensor(102), a steering-device control unit(106) and a lamp control unit(108). The tire pressure sensor senses the damage of a tire depending on the pressure change of the tire. If the damage of the tire is sensed by the tire pressure sensor, the steering-device control unit transfers a lane-departure preventing signal to the steering device to keep a lane. If the damage of the tire is sensed by the tire pressure sensor, the lamp control unit controls one or more of an emergency lamp and brake lamps. |
