The invention discloses a self-vehicle driving risk quantification method and system based on human, vehicle and road angles. The method comprises the following steps: acquiring driving information; based on the driving information, obtaining an own vehicle lane departure risk amount and an own vehicle overspeed risk amount, and further obtaining a first driving risk value representing an own vehicle driving risk at a road constraint angle; based on the driving information, obtaining a collision severity degree and a collision urgency degree of the self-vehicle and the other vehicle, and further obtaining a second driving risk value of a self-vehicle driving risk representing a collision angle of the self-vehicle and the other vehicle; and based on the driving information, obtaining a risk perception factor during driving of the vehicle, and further obtaining a third driving risk value representing the driving risk of the vehicle at the perception angle of the driver. According to the method, the vehicle can be helped to comprehensively, accurately and visually know the risk degree of the driving state of the vehicle, the state is adjusted in time, and driving safety is guaranteed.
