VEHICLE CONTROL SYSTEM

In a vehicle control system, a risk frequency calculation unit counts the number of times that a risk level determination unit determines that a risk level is equal to or higher than a predetermined risk level within a predetermined period. Then, a warning frequency setting unit sets a frequency of warning in accordance with the number of times, counted by the risk frequency calculation unit, that the risk level of the driving operation by the driver is determined to be equal to or higher than the predetermined risk level within the predetermined period and activates a warning device.
