Abstract: A vehicle control apparatus includes at least one processor and at least one memory communicably coupled to the processor. The processor sets a target steering angle every predetermined cycle, on the basis of a curvature radius of a first arc passing through a current position of a vehicle, and controls a steering angle on the basis of the target steering angle. The processor sets the target steering angle by obtaining a second arc passing through the current position and tangent to a traveling direction of the vehicle, on the basis of a sum of minimum distances to the first arc from respective target points on a target path. The processor sets the target steering angle in a second cycle following a first cycle, before the vehicle reaches a position corresponding to the farthest one of the target points used for setting of the target steering angle in the first cycle.
