Abstract
A braking and driving force control apparatus to be provided in a vehicle including front-wheel and rear-wheel longitudinal force generators that generate longitudinal forces of front and rear wheels, respectively. The braking and driving force control apparatus includes: first and second road surface friction coefficient setting units that respectively set first and second road surface friction coefficients; and a braking and driving force distribution control unit. The second road surface friction coefficient is larger than the first road surface friction coefficient. When the front-wheel and rear-wheel longitudinal force generators generate a driving force, the braking and driving force distribution control unit controls an output allotment ratio by using the first road surface friction coefficient. When the front-wheel and the rear-wheel longitudinal force generators generate a braking force, the braking and driving force distribution control unit controls the output allotment ratio by using the second road surface friction coefficient.
