The invention relates to the technical field of automobile control, in particular to an intelligent control system and method for safe driving of a vehicle. The system comprises a system controller, afatigue driving monitoring system, an electric power steering system, an accelerator signal unit, a vehicle speed signal unit and a power domain control system. The fatigue driving monitoring systemoutputs a driver fatigue strength signal, the electric power steering system outputs a steering wheel corner signal, the accelerator signal unit outputs an accelerator opening signal, and the vehiclespeed signal unit outputs a vehicle speed signal to the system controller. The system controller judges the fatigue level according to various input signals and outputs a corresponding instruction tothe power domain control system according to the fatigue level; the system controller sends a vehicle power torque limit value to the power domain control system through fuzzy control according to thefatigue strength and the steering wheel angle change rate, and the power domain control system controls the vehicle according to the vehicle power torque limit value. The safety in the vehicle and the life body safety outside the vehicle are effectively improved.
