1. A control apparatus for controlling a vehicle which includes a driving motor configured to drive the vehicle by outputting motor torque based on a supply voltage from a battery, and an engine configured to drive the vehicle by outputting engine torque, the apparatus comprising:
the control apparatus configured to acquire driving mode data which is calculated based on traffic information from a current position to a destination of the vehicle and dimension information of the vehicle, and control the vehicle to drive to the destination according to a driving mode which is determined by applying a travelling condition of the vehicle to the acquired driving mode data,
wherein a power distribution ratio of the motor torque to the engine torque is included in the driving mode data,
wherein the control apparatus calculates a traffic speed profile as the traffic information by statistically analyzing the traffic speed from the current position to the destination of the vehicle, calculates required driving torque of the vehicle, which is required for securing the traffic speed profile, by applying a predefined vehicle dynamics algorithm to the calculated traffic speed profile, and calculates the driving mode data using a method of calculating the power distribution ratio capable of satisfying the calculated required driving torque,
wherein the control apparatus collects real-time traffic speed information at a current point of time and traffic speed history information at a past point of time corresponding to the current point of time, for a route from the current position to the destination of the vehicle, removes outliers as a measure of dispersion of the collected real-time traffic speed information and traffic speed history information, and then calculates, as the traffic speed profile, an average value of the real-time traffic speed information and traffic speed history information from which the outliers are removed, and
wherein the control apparatus calculates the required driving torque by applying the traffic speed profile and a battery SOC (State of Charge) to the vehicle dynamics algorithm, and calculates the driving mode data using a method of specifying the power distribution ratio at which fuel efficiency is maximized, among a plurality of power distribution ratios capable of satisfying the calculated required driving torque, through a predefined dynamic algorithm.
