<P>PROBLEM TO BE SOLVED: To provide a vacuum pump control method and mounting structure for a diesel hybrid vehicle, capable of appropriately maintaining negative pressure inside a negative pressure tank during EV traveling. <P>SOLUTION: Negative pressure inside the negative pressure tank is detected during EV traveling (Yes in Step S10, Step S11), and when negative pressure runs short, an engine is started and a vacuum pump is driven by idle driving (Yes in Step S12, Step S13). After start of the engine, charge amount of a battery is detected (Step S14), and when the charge amount is below a predetermined value, a clutch is engaged and power generation control is performed by engine traveling (No in Step S15, Steps S19 to S21). When the charge amount of the battery exceeds the predetermined value and a negative pressure value detected again is recovered to a predetermined value, the engine is stopped (Yes in Step S15, Step S16, Yes in Step S17, Step S18). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
