Abstract
A braking-driving force control system is provided in which erroneous vehicle speed detection may be avoided even when a frictional braking power is generated during rotation of an output shaft coupled to an electric driving motor as driving source. When only regenerative braking force is being generated as braking force while the vehicle is traveling, the braking force and the driving force are controlled based on an output shaft side vehicle speed calculated from the rotational state of an output shaft of a driving source, and when the frictional braking power is being generated while the vehicle is traveling, the braking force and the driving force will be controlled based on a wheel side vehicle speed representing the vehicle speed calculated from the rotational state of the vehicle wheel.
