- the air density correction generally increases the target engine output so that the actual generated power of the power generation motor 2 can follow the target generated power regardless of the air density as the air density decreases in the environment in which the vehicle travels. It is embodied as a correction to make.

- the pumping loss of the engine 1 increases, so that the fuel consumption rate of the engine 1 increases (the value after the increase is indicated by B), and the operating efficiency of the engine 1 deteriorates.
- an operation is introduced in which the deterioration of the operating efficiency is suppressed by stopping the implementation of the air density correction while allowing the actual decrease in the engine torque TRQ to the extent possible. To do.
- FIG. 3 conceptually shows an operation according to the present embodiment (hereinafter, may be referred to as “correction cancel”) for stopping the implementation of air density correction.

Then, while the air density correction is basically performed for the decrease in the air density Dair, when the air density Dair decreases beyond the predetermined density Dthr, the region in which the air density correction is stopped, that is, the cancellation Set the area. This is because as the air density Dair decreases, it is necessary to strongly apply the air density correction to secure the output and widen the throttle opening, and the deterioration of the fuel consumption rate becomes remarkable accordingly.

- the cancellation region is set over the entire vehicle speed VSP, while between the second predetermined density Dthrl and the first predetermined density Dthrh.
- the cancellation area is set for the case where the vehicle speed VSP is in the high vehicle speed range.
- the vehicle speed hysteresis has reached the high vehicle speed range from the low vehicle speed range outside the high vehicle speed range (hereinafter referred to as "high vehicle speed determination"), and that the vehicle speed has returned from the high vehicle speed range to the low vehicle speed range. (Hereinafter referred to as “cancellation of high vehicle speed determination”), a difference, that is, hysteresis is added to the threshold value (Vthr) for determination.

- FIG. 6 shows an operation schedule according to the vehicle speed VSP of the engine 1 when traveling on a flat road.
- the solid line Lstr indicates the start line of the engine 1 for different charge state SOCs of the battery 4

- a hysteresis is applied to the vehicle speed when switching the driving points A and B between the case where the output is increased to the driving point B and the case where the output is returned from the driving point B to the driving point A. ..
- the operation schedule of the engine 1 is determined according to the required output for the drive system S, the vehicle speed VSP, and the charge state SOC of the battery 4.
- the engine 1 starts when the required output increases and reaches the corresponding start line Lstr under the actual charge state SOC.
- the power generation motor 2 starts power generation and the battery 4 is charged. Therefore, the operation stop line Lstp is sequentially switched to the one on the high charge state side. After starting, the engine 1 stops when it reaches the operation stop line Lstp according to the charging state SOC.
- the engine 1 is started when the required output reaches the starting line Lstrm at the predetermined vehicle speed Vthr (for example, the first predetermined vehicle speed Vthrh). After that, if the high charge state is maintained, since the operation stop line Lstph is lower than the required output, the engine 1 does not stop and combustion is continued (continuous combustion region).
- the consumption of the battery 4 exceeds the power supply by the engine 1, so that the charged state SOC is kept low, and the operation stop line Lstp becomes low. It is switched to the one on the low charge state side (for example, Lstpm), and combustion is continued.
- the charging state SOC The engine 1 is repeatedly started and stopped by repeating the operation of passing the operation stop line Lstp (intermittent combustion region).

The mode and so on will be repeated.
- the charged state SOC of the battery 4 increases or decreases, and the engine 1 repeats starting and stopping.
- the charged state SOC is held high, so that the frequency of stopping the engine 1 decreases.
- the cancellation area can be defined not only by the vehicle speed VSP but also by the combustion state of the engine 1. For example, it is possible to determine whether it is due to continuous combustion or intermittent combustion from the relationship between the fixed point output Pout and the required output, and the range in which the required output exceeds the fixed point output Pout (indicated by reference numeral A in FIG. 6) is continuous. It is also possible to define the combustion region and the other range (indicated by reference numeral B) as the intermittent combustion region. In this case, the vehicle speed Vthra whose requested output matches the fixed point output Pout is the "predetermined vehicle speed".
- the vehicle speed Vthrh ( ⁇ Vthra) is set as the boundary between the continuous combustion region and the intermittent combustion region, but how much the continuous combustion region can be expanded from the range A to the low vehicle speed side? In other words, how much the boundary between the continuous fuel region A and the intermittent combustion region B can be pushed down from the state shown in the figure to the low vehicle speed side is related to the charge management of the battery 4.
