Patent ID: 8527167

Claim:
A control apparatus of a driving force in case of belt slipping for a vehicle equipped with a V-belt continuously variable transmission where rotation from a power source can be transmitted via a V-belt wrapped around pulleys, a pulley rotation ratio between the pulleys can be continuously changed toward a value corresponding to a target speed ratio by stroking movable sheaves defining pulley V grooves for wrapping the V-belt relative to fixed sheaves in an axial direction, and a slip state ofthe V-belt to the pulleys is controlled to a predetermined slip state by a belt slip control, comprising: a belt slip control detecting unit adapted to detect that the belt slip control is in execution; a belt contact radius ratio calculating unit adapted to calculate a belt contact radius ratio of the V-belt to the pulleys; and a power source output torque determining unit adapted to determine a target power source output torque according to the belt contact radius ratio in execution of the belt slip control in response to signals from the belt slip control detecting unit and the belt contact radius ratio calculating unit.
