    摘要： A target driving force is calculated by an ECU (30) on the basis of an accelerator (40) 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 (20) is controlled according to a target power calculated on the basis of the target driving force, and the load on an engine (10) 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.

    摘要： A control system for a vehicle including a continuously variable transmission (10) is constructed: such that a target output of a prime mover (1) for achieving a target driving force is determined on the basis of the target driving force; such that a target output speed is determined on the basis of the target output; such that a gear ratio of the continuously variable transmission is controlled so that an output speed of the prime mover may be the target output speed; such that a target output torque of the prime mover for achieving the target driving force is determined on the basis of the target driving force; and such that a load of the prime mover is controlled on the basis of the target output torque. The control system further comprises a corrector (6,13,15) for correcting a control quantity to control the load of the prime mover so that the output torque of the prime mover may have the sum of the target output torque and an output torque for keeping the idle run of the prime mover.

    摘要： A flow control valve is located in a coolant circuit that extends through an engine. The flow control valve is operated in accordance with a control mode selected from a full closing control mode, a full opening control mode, and a feedback control mode. When switching from one control mode to another, the flow control valve is controlled in accordance with a transitional control procedure selected from different types of transitional control procedures. The transitional control procedure to be performed is selected depending on which control modes are performed before and after the control mode switching and/or the current condition of the engine. Transitional controlling of the flow control valve is thus appropriately conducted.

    摘要： An engine cooling apparatus includes a flow regulating valve, which adjusts a flow rate of a coolant passing through a radiator provided in a coolant circulation passage of the engine, and an electronic control unit (ECU), which controls an opening of the flow regulating valve such that an engine outlet coolant temperature reaches a necessary target temperature. The ECU sets a basic opening as a feedforward term based on the operation state of the engine. The ECU calculates a final opening from an F/B constant as a feedback term, which is increased or decreased such that the engine outlet coolant temperature reaches the target temperature, and the basic opening. Further, the ECU performs feedback control on the opening of the flow regulating valve based on the final opening. As a result, the responsibility of the coolant temperature control is improved.

    摘要： A cooling system (20) for an internal combustion engine (11) includes a radiator (22) provided in a coolant circulation path of the internal combustion engine, and an actuator (24) that controls a flow rate of a coolant that passes through the radiator. In the cooling system, the actuator is controlled so that a coolant temperature of the engine becomes substantially equal to a target coolant temperature. The cooling system calculates a cooling loss as a quantity of heat removed from the engine by the coolant, based on an operating state of the engine, and calculates a required radiator flow rate, based on the cooling loss, the target coolant temperature, and a temperature of the coolant that has passed through the radiator. The required radiator flow rate represents a quantity of the coolant required to pass through the radiator so as to achieve the target coolant temperature. The cooling system then controls the actuator based on the required radiator flow rate.
