Illustrate that the startup based on the combustion engine 2 of the control setup 9 of hybrid electric vehicle 1 stops controlling according to the diagram of circuit of Fig. 6.
As shown in Figure 6, the control setup 9 of hybrid electric vehicle 1 is when the startup of combustion engine 2 stops the program controlling to start (B01), the output value request (B02) of chaufeur is calculated according to throttle opening, the 1st specified time (after starting holding time) and the 2nd specified time (stopping the holding time afterwards) (B03) is calculated based on the charge volume of battery 5 or the speed of a motor vehicle, the 1st gradual change amount (after starting gradual change amount) and the 2nd gradual change amount (stopping gradual change amount afterwards) (B04) is calculated based on the charge volume of battery 5 and the speed of a motor vehicle, judge whether the judgement (B05) having carried out starting apparatus combustion engine 2.
When this judges (B05) as "Yes", after judgment model conversion, whether the elapsed time have passed through the 1st specified time (after starting holding time) (B06).
When this judges (B06) as "No" (below the 1st specified time), carry out making stopping decision content being reduced to correction (B07) than being judged to be certain value (stopping judging compensation value) that the stopping decision content before starting is little, judge the output value request of chaufeur be whether this little certain value (stopping judgement compensation value) below (B08).
In addition, when this judges (B06) as "Yes" (the 1st specified time passes through), the stopping decision content making to be corrected to little certain value (stopping judging compensation value) is increased to gradually with the 1st gradual change amount (after starting gradual change amount) and is judged to be the stopping decision content (B09) before starting, and judges that whether the output value request of chaufeur is (B08) below stopping decision content during this increases gradually.
When this judges (B08) as "No", return judgement (B06).When this judges (B08) as "Yes", stop combustion engine 2 (B10), return process (B02) (B11).
On the other hand, when above-mentioned judge (B05) as "No", after judgment model conversion, whether the elapsed time have passed through the 2nd specified time (stop after holding time) (B12).
When this judges (B12) as "No" (below the 2nd specified time), carry out making startup decision content rise to the correction (B13) of the certain value (start judge compensation value) larger than the startup decision content be judged to be before stopping, judging whether the output value request of chaufeur is more than this large certain value (start and judge compensation value) (B14).
In addition, when this judges (B12) as "Yes" (the 2nd specified time passes through), the startup decision content making to be corrected to large certain value (start and judge compensation value) reduces to gradually with the 2nd gradual change amount (after stopping gradual change amount) and is judged to be the startup decision content (B15) before stopping, and judges that whether the output value request of chaufeur is (B14) below startup decision content during this reduces gradually.
When this judges (B14) as "No", return judgement (B12).When this judges (B14) as "Yes", starting apparatus combustion engine 2 (B10), returns process (B02) (B11).
The control setup 9 of this hybrid electric vehicle 1 about the combustion engine 2 of setting usually startup decision content and stop decision content, after HEV mode translative mode (combustion engine 2 starts rear), in the 1st specified time (after starting holding time), make stopping decision content dropping to little certain value (stopping judging compensation value), after having carried out patten transformation to EV pattern (combustion engine 2 stops rear), in the 2nd specified time (after stopping holding time), startup decision content has been made to rise to large certain value (start and judge compensation value).In addition, these stopping decision contents relative to the output value request of chaufeur and start the mapping that to utilize with the charge volume of the speed of a motor vehicle and battery 5 be axle of decision content and specified time and calculate.And, at the 1st specified time through later, little by little change to common stopping decision content with the 1st gradual change amount (after starting gradual change amount).In addition, at the 2nd specified time through later, little by little change to common startup decision content with the 2nd gradual change amount (after stopping gradual change amount).
