Abstract: PROBLEM TO BE SOLVED: To provide a technology which can properly determine an abnormality of air-fuel ratio feedback control in each of the case that a target air-fuel ratio is rich and the case that the target air-fuel ratio is lean.SOLUTION: An ECU 1 as an engine control device comprises a control part 41 and a determination part 42. The control part 41 performs air-fuel ratio feedback control for correcting a fuel injection amount to an engine 3 so that an actual air-fuel ratio is converged to a target air-fuel ratio on the basis of an output of an air-fuel ratio sensor 17. The determination part 42 determines whether or not the air-fuel ratio feedback control is abnormal, and when determines that the feedback control is abnormal, prohibits the execution of the air-fuel ratio feedback control by the control part 41. Then, the determination part 42 determines whether or not the air-fuel ratio feedback control is abnormal by different conditions which are different in the case that the target air-fuel ratio is rich, and in the case that the target air-fuel ratio is lean.SELECTED DRAWING: Figure 2

Title: Control device of transmission
Inventor: MIYAJI HIROSHI
IPC: F16H37/02
Filed: 2017-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a control device of a transmission capable of suppressing occurrence of belt slip in switching modes.SOLUTION: In switching a mode from a split mode to a belt mode, a transmission torque capacity of a clutch C1 at a release side is lowered (T1) in a stage when differential rotation (rotating speed difference between secondary rotating speed and output rotating speed) occurs at both sides of a clutch C2 at an engagement side. Thus the clutch C1 is kept in a half clutch state, slip occurs in the clutch C1, rotation at a continuously variable transmission mechanism side is blown up, and the differential rotation at both sides of the clutch C2 is rapidly reduced. When the differential rotation is reduced to a prescribed value, a transmission torque capacity of the clutch C2 is increased (T2). Before the transmission torque capacity of the clutch C2 is increased, a belt compression pressure of the continuously variable transmission mechanism is increased higher than a necessary compression pressure.SELECTED DRAWING: Figure 6

Abstract: PROBLEM TO BE SOLVED: To properly determine an attachment state of two current sensors attached to the electric wirings at the side of an electric power system rather than at the side of an interconnection system in an electric power system in which an inverter circuit of a single-phase two line system is interconnected to any of two voltage lines of the electric power system of a single phase three wiring system and a neutral line.SOLUTION: When the current fluctuation of a load capacity is detected in one current sensor only of the two current sensors at the time of connecting an inner load to the power system in a state that the power generation is stopped, an attached state determination device of the current sensor determines that one current sensor is attached to an interconnected voltage line, and another sensor is attached to the voltage line not interconnected. The attachment direction of one current sensor is determined depending on whether the current fluctuation is in the same phase or in the reversed phase for the voltage of the voltage line interconnected in the current fluctuation. When the current fluctuation is generated in the other current sensor, the attachment direction of the other current sensor is determined depending on whether the current fluctuation is in the reversed phase or in the same phase for the voltage of the voltage line interconnected in the current fluctuation when the current fluctuation is generated in the other current sensor.SELECTED DRAWING: Figure 2
