A system for controlling electric power of a vehicle having a fuel cell is provided. The system includes a fuel cell that generates electric energy by receiving fuel and oxidizing gas and a battery that receives the electric energy of the fuel cell to charge or discharge the battery for supplying the electric energy. A sensor sense a driving state of the vehicle. A controller controls charging or discharging of the battery based on the driving state sensed by the sensor.

A vehicle control apparatus based on a precise load level using a GPS includes: a load level calculator to determine a load level of a road based on GPS information; a load level controller that classifies the road into a plurality of regions based on the determined load level and differentially controls an engine power output for each of the regions; and a storage to store a map for the engine power output for each of the regions.

This vehicle control device is provided with: a determination unit for determining whether proscribed conditions are satisfied, including the inability to determine that a longitudinal acceleration target value is fluctuating and the ability to determine that the longitudinal acceleration of a vehicle is fluctuating; and a cooperative control unit which, on the condition that it has been determined that the prescribed conditions are satisfied, performs a braking/driving cooperative process to hold a torque output from one of a driving torque generation device and a braking torque generation device at a value which is larger than the torque at the point in time at which the prescribed conditions were met, and adjusts the torque output from the other device through feedback control using the longitudinal acceleration target value and the longitudinal acceleration of the vehicle.
