Method for calculating social value orientation of driver in driving interaction scene

The invention belongs to the field of road vehicle control, and relates to judgment or calculation of driving parameters of a road vehicle driving control system, in particular to a driver social value orientation calculation method in a driving interaction scene, which specifically models a driver decision process by using a cost function and a reward function in combination with traffic environment information; constructing an interaction strength Hessian matrix, and determining an interaction strength value by calculating the sensitivity of the utility value of the main driver to the control input of other drivers so as to determine an interaction object; parameters in the utility function are dynamically adjusted according to real-time observed driving behaviors and environment changes of the current vehicle and the strongest interaction vehicle, the social value orientation of the driver is calculated, the method not only can adapt to the complex and changeable driving environment, but also can accuratel
