摘要： An electric power steering (EPS) apparatus 1 includes a motor 12, an EPS actuator 10, a torque sensor 14, and an ECU 11. The EPS actuator 10 uses the motor 12 as a drive source to apply assist force to a steering system, thereby assisting a steering operation. The torque sensor 14 detects a steering torque τ of the steering system. The ECU 11 controls the operation of the EPS actuator 10. Based on the steering torque τ detected by the torque sensor 14, the ECU 11 computes a basic shift amount εts_b of the assist force applied to the steering system. The ECU 11 determines which one of returning, holding, and turning is the state of the steering operation. When the state of the steering operation is returning or holding, the ECU 11 executes compensation control for correcting the steering torque τ, which is used in the computation of the basic shift amount εts_b of the assist force, thereby increasing the assist force applied to the steering system. The ECU 11 subjects the steering torque shift control amount εts to a filtering process using a low pass filter, thereby inhibiting the steering torque shift control amount εts from sharply changing. When the state of the steering operation is turning, the ECU 11 changes a filter constant of the low pass filter so as to reduce the filtering effect.

摘要： A current command value computing section includes an integration control computing section. Based on an integration of the steering torque τ, the integration control computing section computes a steering torque integration control amount Iint*, which is a compensation component for increasing the assist force. The integration control computing section functions as a determining device that determines whether the vehicle is traveling forward in a straight line. When the determining device determines that the vehicle is traveling forward in a straight line, the integration control computing section outputs the steering torque integration control amount Iint* to an adder. The current command value computing section superimposes the steering torque integration control amount Iint* on a basic assist control amount Ias* computed by a basic assist control section, and outputs the obtained value, as a current command value Iq* corresponding to a target assist force, to an output section.

摘要： The present invention provides an electric power steering device enabled to compensate for the influence of the inertia of a steering-assisting-force generating motor on steering with accurate timing even when a steering direction is reversed at high speed. Based on steering torque and a rotation angular speed of a steering-assisting-force generating motor, a steering angular acceleration correspondence value is obtained. The device has means for regulating a gain, which is multiplied to a change acceleration of the steering torque. The motor is controlled so that the steering assisting force is corrected according to a motor output correction value obtained on the basis of the relation between the motor output correction value and the steering angular acceleration correspondence value, which is preliminarily determined and stored in such a way as to compensate for the influence of the inertia on steering, and the obtained steering angular acceleration correspondence value.

摘要： When engine rotation speed is increasing in a compression stroke injection mode, a control device determines that a crank angle at injection end timing of an injector deviates toward a delayed crank angle side and performs additional ignition at timing when (or immediately before or after) a crank angle at actual injection end timing of the injector of a present injection cylinder is reached. Thus, even when the crank angle at the injection end timing deviates toward the delayed crank angle side with respect to preset original ignition timing, a combustion state can be stabilized by performing the additional ignition at timing, at which a suitable stratified mixture gas is formed in a cylinder, through the execution of the additional ignition at the timing substantially the same as the actual injection end timing.

摘要： An individual-cylinder air-fuel ratio estimation model is designed so as to consider the mixing of gases exhausted from adjacent combustion cylinders, and a movement by which a mixed gas arrives at the position of an air-fuel ratio sensor, in order that influences ascribable to the intervals (combustion intervals) of the adjacent combustion cylinders may be reflected on the estimation values of individual-cylinder air-fuel ratios. In evaluating the mixing of the gases which are exhausted from the adjacent combustion cylinders, there are considered the lengths and shapes of the exhaust manifolds of the respective combustion cylinders. In evaluating the movement by which the mixed gas arrives at the position of the air-fuel ratio sensor, there are considered a distance or volume from the confluence to the position of the air-fuel ratio sensor, and the exhaust gas quantities of the respective combustion cylinders.
