摘要： A drive force control system for a vehicle configured to change a torque to propel a vehicle certainly in a required amount by controlling output torques of an engine and a motor. A controller is configured to: calculate a required amount of change in synthesized torque of an engine torque and a motor torque; calculate a required amount of change in the engine torque and a required amount of change in the motor torque based on the required amount of change in the synthesized torque; select one of the engine and the motor whose torque will be changed further than a limit value; and adjust the torque of the selected prime mover by a counter torque.

摘要： A control system is applied to an internal combustion engine having a plurality of cylinders, a variable compression ratio changer configured to change the compression ratio of each of the cylinders of the internal combustion engine individually, in-cylinder injection valves that inject fuel into the respective cylinders, and in-passage injection valves each of which injects fuel into an intake passage corresponding to each of the cylinders. To reduce differences in the air-fuel ratio among the cylinders during changing the compression ratio, the control system makes the proportion of the quantity of fuel injected through the in-passage injection valves to the total quantity of fuel injected through the in-cylinder injection valves and the in-passage injection valves larger during the time in which the compression ratios of all the cylinders are being changed than during the time in which the compression ratios of all the cylinders are fixed.

摘要： A control system for a vehicle that executes a feedback control properly to adjust a speed of a predetermined rotary member to a target speed. A controller is configured to: calculate an amount of change in a torque applied to the rotary member by one of the torque devices, in accordance with operating conditions of the torque devices; and calculate an amount of change in the torque applied to the rotary member by another one of the torque devices, based on a target amount of change in a synthesized torque of the torques of the torque devices and the amount of change in the torque applied to the rotary member by one of the torque devices.

摘要： An electronic control unit of a control device for an internal combustion engine executes, for a first cycle, first drive processing for controlling an actuator such that a pin drive operation is executed for switching from a first cam to a second cam, executes second drive processing for controlling the actuator such that the pin drive operation is executed again for a second cycle, and executes abnormality determination processing for determining that a cam switching mechanism has an abnormality in a case where a pin returns to a reference position by using a pin return section following a cam switching section of the first cycle after the execution of the first drive processing and the pin returns to the reference position by using the pin return section following the cam switching section of the second cycle after the execution of-the second drive processing.

摘要： At crank angle CA10 at which the switch request of the drive cam was issued, the ejection operations of the pins at all the solenoid actuators started simultaneously. The ejected pins are seated on the cam carriers at erank angle CA12. The pin seated on the cam carrier moves along the grooves in accordance with the rotation of the cam carrier. The earliest finish timing of the switch operation of the drive cam is at crank angle CA13 (#4 cylinder). At the crank angle CA13, drive of the fuel injector and the ignition device in each cylinder is permitted.

摘要： 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.

摘要： 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.
