摘要： A control system for a hybrid vehicle that can prevent an overcharging of a battery even if a wheel speed drops abruptly. The hybrid vehicle comprises: an engine; a generator that is driven by the engine; a drive motor that generate a drive torque; and a battery. The electric power generated by the generator is supplied directly to the battery or the drive motor. A controller is configured to determine whether the drive wheel will be locked, and to reduce the electric power generated by the generator less than an acceptable input power to the battery if the drive wheel is expected to be locked.

摘要： An object is to carry out an abnormality diagnosis for a variable compression ratio mechanism without adding any special hardware configuration for estimating a compression ratio. An abnormality diagnostic device for a variable compression ratio mechanism adapted to be applied to an internal combustion engine comprises a controller configured to calculate a predetermined rotational speed difference which is a rotational speed difference, between an engine rotational speed at a predetermined crank angle before or after compression top dead center and an engine rotational speed in the vicinity of the compression top dead center for a predetermined cylinder at the time of carrying out fuel cut processing, set a reference range of the predetermined rotational speed difference, and make a diagnosis that abnormality has occurred in the variable compression ratio mechanism when the predetermined rotational speed difference is out of the reference range.

摘要： A cooling device includes a first cooling medium circuit for circulating a cooling medium that passes through a main body of an engine to a first heat exchanger, a second cooling medium circuit for circulating a cooling medium that passes through the main body to a second heat exchanger, a control valve that is commonly used in the first and second cooling medium circuits, and a control device. The control valve includes a rotatable rotor, and is configured such that a rotation range of the rotor includes a water stop section in which the circuits are both closed. The control device restricts output power of the engine in a period in which the rotation angle is in the water stop section, when the rotor rotates via the water stop section at an operating time of the control valve.

摘要： A shift control system which can reduce a shift shock is provided. A target torque determiner set a target torque of an engine based on an accelerator position. An actual torque determiner calculates an actual torque of the engine in the inertia phase. A controller calculates an integrated value of a difference between the target torque and the actual torque from a commencement of the inertia phase to a predetermined time point before a termination of the inertia phase, and corrects the target torque in a remaining period between the predetermined time point and the termination of the inertia phase.

摘要： A cooling apparatus includes a coolant circulation channel for returning a coolant that passes through an engine main body, after causing the coolant to exchange heat with a radiator, device(s) and a heater, respectively. A multifunction valve as a rotary valve that is capable of adjusting an amount of coolant that is circulated to the radiator, device(s) and heater, respectively, is disposed in the coolant circulation channel. When automatic stopping of the engine is performed by idle stop-start control, during the automatic stopping the control apparatus continues to execute valve control of the multifunction valve that is being executed during the operation before the start of the automatic stopping.

摘要： A change in a valve opening degree from an opening degree (a) to an opening degree (d) is caused by a decrease in a radiator outlet water temperature, and at such time a flow rate through a radiator enters a boiling region. Therefore, when such entry is predicted, a target engine outlet water temperature is forcedly changed from 105° C. to 100° C. Thereupon, the valve opening degree is changed from the opening degree (a) to an opening degree (f). The flow rate through the radiator when the valve opening degree is the opening degree (f) is greater than the flow rate through the radiator when the valve opening degree is the opening degree (d), and furthermore, the flow rate through the radiator does not enter the boiling region while the valve opening degree is changing from the opening degree (a) to the opening degree (f).
