A flat conductor material before being formed into a flat conductor includes a in-slot conductor portion where a conductor having rectangular cross-section is continuously pre-formed in a zigzag pattern on a same plane and a plurality of conductors are so arranged as to be overlapped in the slot of the stator core, a coil end conductor portion where a plurality of conductors are arranged while overlapping as a coil end on the outside of the slot, and a bending portion which bends to connect both conductor portions. When the flat conductor is formed, the bending portions located at the opposite ends of the in-slot conductor portion are grasped by means of a pair of grasping tools, and the in-slot conductor portion is clamped by means of a twist tool in the setting process. Thereafter, the bending portions are twisted and bent into crank-shape in the machining process by displacing a predetermined axis to a predetermined direction while rotating the twist tool about the axis. The flat conductor is obtained by carrying out the setting process and the machining process entirely for the plurality of in-slot conductor portions.

Firstly, a flat conductor raw wire is formed in a rectangular cross-section and bent in a continuous meandering pattern in a same plane to include in-slot wire portions arranged in each slot of the stator core, coil-end wire portions arranged as a coil end outside the slots, and bent portions joining the in-slot wire portions and the coil-end wire portions. Thereafter, in a setting step, the bent portions located at the opposite ends of the in-slot wire portion are grasped by a pair of grasping tools and the in-slot wire portion is grasped by a twisting jig. Next, in a processing step, the bent portions are twisted and bent into crank-shape by displacing a predetermined axis to a predetermined direction while rotating the twisting jig about the axis. The flat conductor is obtained by performing the setting step and the processing step each of the in-slot wire portions.

The invention relates to an engine operation start control device of a hybrid vehicle comprising a power output device having an internal combustion engine and an electric motor. In this hybrid vehicle, an intermittent control for intermittently operating the engine can be performed and when the operation of the engine is started during the intermittent control being performed, a cranking of the engine is performed until the engine speed reaches a target engine speed. According to the invention, in case that the operation of the engine is started when the speed of the hybrid vehicle is higher than or equal to a predetermined speed and a power required for the power output device is larger than or equal to a predetermined power, the engine speed, which increases as the speed of the hybrid vehicle increases, is set as the target engine speed.

When there is a request for heating prior to completion of warm-up of an engine, an air-conditioner electronic control unit uses a PTC heater as a heat source for heating and cancels a warm-up request for the engine if the state of charge of a battery is high, while the control unit uses the engine as a heat source for heating and sets a warm-up request for the engine if the state of charge of the battery is low. Thus, stopping the engine for heating is less frequently inhibited while ensuring the heating performance.

A hybrid vehicle is mounted with a traction motor, a power storage device for storing electric power input to and output from the traction motor, an engine, and a power generation mechanism to generate charging electric power for the power storage device by an output from the engine. An ECU sets charging/discharging electric power of the power storage device to control SOC of the power storage device to be within a predetermined range centered about a SOC control target in a running mode with the engine operating. The output from the engine is set to ensure the charging/discharging electric power. The ECU sets the charging/discharging electric power such that the power storage device is discharged to an extent corresponding to a predetermined SOC higher than the lower limit SOC according to requirement power required for vehicle running, even when the SOC is lower than the SOC control target.

Disclosed is a vehicle control apparatus which can execute a start-up control for improving acceleration performance at the time of starting an internal combustion engine during the running of a hybrid vehicle. When a hybrid ECU determines that a predetermined time has not yet elapsed after termination of the start-up control of the engine, and that the hybrid vehicle is in a high speed, high load condition, but not in a warming-up state, the hybrid ECU sets a value Nupest2 larger than a value Nupest1, that is usually set as a maximum value Krmx of a rise rate of an engine rotational speed.
