1. A platoon driving control system of a vehicle, comprising:
a detector configured to detect an obstacle positioned in a front according to a driving direction of a vehicle included in a platoon;
a processor; and
a memory coupled to the processor and storing an algorithm that, when executed by the processor, causes the processor to:
estimate a slope of a road on which the platoon or the vehicle included in the platoon is driving,
calculate a slope braking time according to the estimated slope,
calculate a required braking time based on a calculated predicted time to collision (TTC),
determine a braking strategy such that the calculated slope braking time is reflected at the calculated required braking time,
control a driving of the platoon based on the obstacle detected by the detector and the braking strategy,
determine a speed profile of a following vehicle over time based on a speed profile of a preceding vehicle included in the platoon over time, and
determine that controlling of the speed profile of the following vehicle over time is delayed by a preset time rather than the speed profile of the preceding vehicle over time,
wherein the preset time is a constant value, or is set based on a separation distance between the preceding vehicle and the following vehicle and a vehicle speed.
