The invention discloses an intelligent auxiliary system and method for safe driving of an automobile, and the system is characterized in that the system comprises a road condition resolving module which is used for judging the current road condition by collecting the automobile speed and the wheel speed and dynamically resolving the current static friction and dynamic friction states of wheels; the front camera is used for shooting visibility, visual distance and light irradiance of snowfield or sunlight in the front in real time; the central calculation module is used for receiving the road condition information from the road condition resolving module, receiving data from a front camera and calculating a current appropriate speed limit threshold value, an anti-sideslip threshold value, an intelligent brake threshold value and an appropriate front windshield glass perspective parameter through a built-in algorithm; and the vehicle body control system is used for receiving the parameters calculated by the central control module, judging and entering a corresponding safety mode. Through comprehensive calculation of the system, the purposes of automatically limiting the vehicle speed, automatically starting the anti-skid driving mode and automatically adjusting the perspective of the front windshield glass are achieved, so that the optimal driving visual field is achieved, and then driving safety is improved.
