1. A system for preventing collision of a vehicle, the system comprising: a processor configured to execute:
a map based collision determinator configured to output a first vehicle target speed using a map with respect to a parking space and a current location of the vehicle; a front and rear parking assist system (FRPAS)-vehicle speed based collision determinator configured to output a second vehicle target speed using a measured value of the FRPAS and a current vehicle speed; a FRPAS stop determinator configured to output a third vehicle target speed using the measured value of the FRPAS; a vehicle speed excess stop determinator configured to determine whether the current vehicle speed exceeds a preset reference vehicle speed and to output a fourth vehicle target speed; and a collision prevention operation manager configured to receive at least one of the first vehicle target speed, the second vehicle target speed, the third vehicle target speed, and the fourth vehicle target speed and to compute a final vehicle target speed corresponding to input target speeds to prevent collision between the vehicle and an obstacle, wherein the map based collision determinator acquires obstacle location information using the current location of the vehicle and generates the map including the obstacle location information; wherein a braking control module configured to receive the computed final vehicle target speed and to brake the vehicle, substantially equating the current vehicle speed to the final vehicle target speed.
