Second setting is not based on driver manipulations. When engine makes the vehicle traction force source, first setting "a" is expressed in torque units (S200). Second setting "A" is expressed in traction force units (S400). On converting physical magnitudes, conversion into units of traction forces (S500) is carried out. First setting "a" (S300) is memorised. If first setting is selected after conflict settling (no S600), memorised first setting "a" (S900) is set for the engine.

EFFECT: better vehicle controllability.
