An automatic fillet welding method for effecting the welding by rotating a welding electrode and thereby rotating an arc at a high speed. By rotating the arc with a predetermined rotation direction, rotation speed and rotation diameter, a weld metal is prevented from running downward thereby forming a bead having uniform leg lengths and an excellent depth of penetration.

Five infrared sensors are located in different height positions between respective main bodies 10A to 10H, and all of these infrared sensors transmit and receive 35 infrared rays pulse-coded in conformity with a start-stop system. In addition, these pulse-coded infrared rays have the signal width of, for example, 450 μs, and are serially transmitted with a predetermined delay time in a period of 20 ms by a delayed synchronizing-signal. Intrusion surveillance is performed by identifying the pulse codes of these infrared rays. According to this, since not only interference among a plurality of infrared sensors is prevented, but also infrared rays are outputted in a short time, the occurrence of false alarms etc. decreases remarkably.

In a hybrid vehicle of the invention, the control procedure corrects an idling intake air flow Qidl to enable an engine immediately after its start to generate an output power Pe that is substantially equivalent to an engine power demand Pe*. After the correction, the control procedure controls the engine to have an intake air flow Qe with reflection of an intake air flow correction value Qec and controls a motor MG1 to generate electric power by using the output power Pe of the engine and to charge a battery with the generated electric power within an input limit Win of the battery. The control of the invention ensures that the output power Pe of the engine does not exceed the engine power demand Pe* in restriction of the charge level of the battery. This arrangement effectively prevents the state of charge SOC of the battery, which is charged with the electric power generated by the motor MG1, from exceeding the input limit Win.

摘要:
The control technique of the invention sets smaller values to an engine stop reference value and an engine start reference value in the state of use of a regular fuel, compared with values in the ordinal state. When a calculated engine power demand Pe* is less than the engine stop reference value, the control stops the operation of the engine. When the calculated engine power demand Pe* exceeds the engine start reference value, on the other hand, the control starts the operation of the engine. This arrangement facilitates the start of the engine in the state of use of the regular fuel, compared with the start in the ordinary state. A corrective revolution speed ΔN is added to a target revolution speed Ne* of the engine, in order to respond to a decrease in output power from the internal combustion engine.
摘要:
A hybrid automobile runs by transmitting a power from an engine and a power from a motor-generator MG2, and can store a part of the power from the engine and an electric power generated by a motor-generator MG1. In this hybrid automobile, a power requirement Pr* of a drive shaft is set based on an accelerator opening, and a battery charge electric power Pbi is set based on SOC, and the sum of the power requirement Pr* and the battery charge electric power Pbi are set as an engine target power Pe*. When the engine target power Pe* is less than a predetermined minimum value Plow, the engine target power Pe* is changed to the minimum value Plow. Further, in accordance with this change, the battery charge electric power Pbi is also changed, and the engine and the motor-generators MG1, MG2 are operated. Since the minimum value Plow is set to be a value such that the efficiency with respect to the output of the engine becomes optimal, it is possible to prevent the engine from being operated in a low output region where the efficiency is low.
