Abstract: A control device is configured, if, although the control device has caused a cam switching device to perform a first cam switching operation for switching the profiles of all the valve-driving cams of a plurality of cylinders from a first profile to a second profile, the profiles of all the valve-driving cams of the plurality of cylinders do not coincide with the second profile, to cause the cam switching device to perform a second cam switching operation for switching the profile of the valve-driving cam for at least one or more normal cylinders that are one or more cylinders at which the switching of profiles to the second profile has succeeded.

Abstract: In starting the engine, if it is determined that large cams are not completely prepared for all driving cams, valve closing timings of all intake valves are changed by driving the VVT so that all of the cylinders have equal in-cylinder filling efficiency. A fuel injection amount of each cylinder is determined by a feedforward control assuming that the large cams are completely prepared for all of the driving cams. When the valve closing timing of all of the intake valves are changed by driving the VVT to equalize the in-cylinder filling efficiencies of all of the cylinders, all of the cylinders have substantially equal in-cylinder air-fuel ratios.

Abstract: A cooling system for a hybrid vehicle that cools cooling medium for an air conditioner without reducing a driving performance, irrespective of a running condition. A detector detects data relating to operating conditions of a high-current device cooling circuit, a supercharger cooling circuit, a high-current device, an engine, a supercharger, and the hybrid vehicle. A controller selects one of a first water passage and a second water passage by manipulating a control valve based on the data collected by the detector, in such a manner as to maximize an amount of heat transferred from the cooling medium to high-current device cooling water or supercharger cooling water.

Abstract: A cooling apparatus of vehicle driving apparatuses of the invention controls flow of cooling water so as to cool engine cooling water by at least two radiators when a requested ability of cooling an internal combustion engine, is equal to or larger than a requested ability of cooling a hybrid device. The number of the radiators used for cooling the engine cooling water is larger than the number of the remaining radiator(s). The cooling apparatus controls the flow of the cooling water so as to cool device cooling water at least two radiators when the requested ability of cooling the hybrid device, is larger than the requested ability of cooling the internal combustion engine. The number of the radiators used for cooling the device cooling water is larger than the number of the remaining radiator(s).

Abstract: In a system that selects a large-cam as a driving cam at a time of a start of an engine, when an engine stop request is output, it is determined whether there is a small-cam cylinder for which a small-cam is selected as the driving cam. In a case where it is determined that there is a small-cam cylinder, a switching command for switching the driving cam from the small-cam to the large-cam is output. When an engine start request is output, the above determination is performed again. In a case where it is determined that there is a small-cam cylinder, the switching command is output to all solenoid actuators again. In addition, the drive of the fuel injector is suspended until the switching operation of the driving cam is completed for all cylinders.

Abstract: An internal combustion engine system is provided with a cam switching device including a cam groove provided on the outer peripheral surface or a camshaft and an actuator capable of protruding, toward the camshaft, an engagement pin that is engageable with the cam groove. The internal combustion engine system is configured, in causing the cam switching device to perform a cam switching operation, to control the actuator such that the engagement pin is seated on a forward outer peripheral surface which is located more forward than an end of the cam groove on the forward side with respect to an insert section of the cam groove in the rotational direction of the camshaft.

Abstract: A cooling system of a hybrid vehicle includes a radiator, an openable and closable first shutter, an openable and closable second shutter, and a control device. The radiator is placed forward of an internal combustion engine and a heat generation device configured to generate heat along with operation of the drive motor, and the radiator communicates with the heat generation device and the internal combustion engine such that a coolant circulates through the internal combustion engine and the heat generation device. The first shutter extends from a front end of an undercover so as to cross between the radiator, and the heat generation device and the internal combustion engine. The second shutter extends between a front end part of the undercover and a lower part of the radiator. The control device controls opening and closing of the first shutter and the second shutter.
