A target driving force is calculated by an ECU on the basis of an accelerator opening and a vehicle speed, and a rounded target driving force value (or a corrected target driving force), as gradually changed from the driving force, is determined in the course to reach the target driving force. On the other hand, a rounded target power value (or a corrected target power) is determined on the basis of the rounded target driving force value. Moreover, the gear ratio of a CVT is controlled according to a target power calculated on the basis of the target driving force, and the load on an engine is controlled on the basis of the rounded target power value, so that the reduction in the power characteristics or the physical discomfort, as might otherwise be caused by the difference in the response between the engine and the CVT, is loosened.
A control system for a vehicle including a power source and a continuously variable transmission capable of changing gear ratios continuously, in which a target driving force is calculated on the basis of an acceleration demand and a vehicle speed, and a target power of the power source is calculated on the basis of the target driving force so that said continuously variable transmission may be controlled to achieve the target power, and in which a target torque of the power source is calculated on the basis of said target driving force so that said power source is controlled to achieve the target torque, comprising:
A control system for a vehicle including a power source and a continuously variable transmission having a torque converter capable of changing gear ratios continuously, in which a target driving force is calculated on the basis of an acceleration demand and a vehicle speed, and a target power of the power source is calculated on the basis of the target driving force, so that said continuously variable transmission may be controlled to achieve the target power, and in which a target torque of the power source is calculated on the basis of said target driving force and the speed of said power source so that said power source is controlled to achieve the target torque, comprising:
