The invention discloses a vehicle intelligent safety decision-making method based on a driving safety field, comprising the following steps:step 1. pre-providing a driving safety field model and a driving risk identification model and a driving safety field model, in an electronic control unit of a vehicle or in a central computer system of a intelligent traffic management system; wherein, the driving safety field model is used to reflect change in traffic risk over time and space, and is established by analyzing the effect of factors of a driver-vehicle-road system on a traffic system;step 2: using the driving safety field model to acquire a current optimal driving speed of the vehicle and safe distances between the vehicle and objects outside the vehicle when the traffic system is in a steady state; andstep 3: acquiring, according to the current optimal driving speed and the distances obtained in step 2, a minimum value action amount of the driving risk identification model,using a risk normalized evaluation index to comprehensively describe and quantitatively evaluate dangerous driving situation of the vehicle, and then acquiring a current driving risk level value of the vehicle.The invention can achieve the safety regulation of the road traffic system, which is beneficial to reduce the incidence of road collision traffic accidents.
