Abstract:
1. A vehicle control device comprising: circuitry that computes a future travel locus of a vehicle by using an evaluation function; and a travel road surface information memory that stores travel road surface information regarding a travel road surface on which the vehicle travels, wherein the circuitry variably sets a convergence criterion for the evaluation function according to the travel road surface information stored in the travel road surface information memory, the convergence criterion being related to a degree of priority of a computation time of the travel locus and a degree of priority of a computation accuracy of the travel locus, the convergence criterion being a function of an error, and the circuitry setting the error based on a road width of the travel road surface, radius of curve of the travel road surface, a friction coefficient of the travel road surface, and an allowed calculation time that elapses before control of the vehicle starts.
