DESIGN METHOD AND VEHICLE CONTROL DEVICE

The disclosed design method is one for output control of a left driving source and a right driving source in a vehicle. The design method includes: preparing a sum model modeling motion states while the vehicle is running straight, and a difference model modeling motion states while the vehicle is cornering; calculating an equivalent sum value corresponding to a sum of a left-axle input/output including an input parameter or an output parameter of the left driving system and a right-axle input/output including an input parameter or an output parameter of the right driving system (A), and an equivalent difference value corresponding to a difference between the left-axle input/output and the right-axle input/output (A); grasping motion states while the vehicle is running straight by applying the equivalent sum value to the sum model (A); and grasping motion states by applying the equivalent difference value to the difference model (A).
