、過給時にはクルーズコントロールかできなくなる。This type of cruise control device generally uses a diaphragm actuator as a mechanism to open and close the throttle valve depending on the relationship between the actual vehicle speed and the set vehicle speed, and in the case of non-turbo vehicles, there is always negative pressure in the intake pipe. Therefore, as shown in Japanese Utility Model Publication No. 56-17702, for example, the actuator is driven by the pressure difference between the suction pipe negative pressure and the atmospheric pressure. However, in a turbocharged vehicle, the pressure in the intake pipe becomes positive during supercharging, so if a system such as the prior art described above is used, only cruise control can be performed during supercharging.

けである。Therefore, a cruise control device 12 is attached to the throttle valve 6, and this device 12 has a diaphragm 14 of a diaphragm actuator 13 connected to an operating lever 16 of the throttle valve ↑6 via a wire 15. . Actuator 13 is diaphragm 1
4 has a high pressure chamber 17 on one side, and a low pressure chamber 18 on the other side, and a return spring 19 is biased against the diaphragm 14 in the low pressure chamber 18.
0 communicates with the upstream side of the throttle valve 6, and the low pressure chamber 18
are similarly connected by a passage 22 having a high pressure valve 21,
Atmospheric pressure or supercharging pressure is applied. The low pressure chamber 18 further includes a low pressure valve 23. Passage 25 with check valve 24
Another check valve 27 is provided in a passage 26 which communicates with the downstream side of the throttle valve 6 and which branches from the passage 25 and communicates with the atmosphere.

閉じるように回路構成される。Here, the check valve 24 opens when the suction pipe is under negative pressure and closes when the supercharging pressure is applied, and the check valve 27 is closed when the suction pipe is under negative pressure and opens otherwise. As a result, suction pipe negative pressure or atmospheric pressure acts on the low pressure chamber 18. Then, the vehicle speed sensor 28 and the constant speed running control switch 29 control the high pressure valve 21 and the low pressure valve 23 via the control circuit 30 to open one and close the other depending on the relationship between the actual vehicle speed and the set vehicle speed. The circuit is configured as follows.

なる。Next, the operation of the cruise control device configured as described above will be explained. First, to explain the pressure difference obtained on the engine side during non-supercharging and supercharging with reference to FIG. 2, the upstream side of the throttle valve 6 is approximately atmospheric pressure in non-supercharging FIia, and the The supercharging pressure gradually increases in the starting supercharging region, and is eventually controlled at a substantially constant level by the supercharging pressure control device 11, resulting in a curve PH, and the positive pressure that changes in this way is directly introduced into the actuator 13. be done. On the other hand, on the downstream side of the throttle valve 6, a large suction pipe negative pressure exists in the non-supercharging region a, and in the supercharging region, the suction pipe negative pressure decreases as the supercharging pressure increases; is introduced into the actuator 13 by the check valve 24. Next, when the downstream side of the throttle valve 6 becomes positive pressure,
The check valve 24 is closed and the pressure is maintained at atmospheric pressure by the check valve 27, and as a result, the pressure on the low pressure chamber 18 side of the actuator 13 becomes lower than atmospheric pressure as indicated by the curve PL. In this way, the substantially equal pressure difference ΔP between the pressure curves PH and PL always acts on the high pressure chamber 17 and the low pressure chamber 18 of the actuator 13 throughout the entire range during non-supercharging and supercharging. It will also be possible to use cruise control.

プリング力がバランスし、その状態に保持される。Therefore, when a desired vehicle speed is set using the switch 29 during constant speed driving, if the set vehicle speed is smaller than the actual vehicle speed determined by the vehicle speed sensor 28, the control circuit 30
The low pressure valve 23 is closed by the signal from the high pressure valve 21, and the pressure on the upstream side of the throttle valve equally acts on both the high pressure chamber 17 and the low pressure chamber 18 of the actuator 13. Therefore, the diaphragm 14 of the actuator 13 is displaced to the left to reduce the opening degree of the throttle valve 6, and the actual vehicle speed accordingly decreases. On the other hand, when the set vehicle speed is higher, the high pressure valve 21 closes, the low pressure valve 23 opens, and a lower pressure acts on the low pressure chamber 18 than the high pressure chamber 17.
Therefore, the diaphragm 14 is displaced to the right to increase the opening degree of the throttle valve 6, and the actual vehicle speed also increases accordingly. When the actual vehicle speed and the set vehicle speed match, the high pressure valve 21 or the low pressure valve 23 closes, and the actuator 13
The pressure difference between the two chambers 17 and 18 and the spring force of the spring 19 are balanced, and this state is maintained.

ズコントロールをすることが可能になる。As is clear from the above description, according to the present invention, in the cruise control device 12 of a turbocharged vehicle, a predetermined pressure difference acts on the actuator 13 for operating the 1 liter valve even during supercharging. , it will be possible to use cruise control over the entire area.

ましい。In addition, since the pressure difference in each region is generated by selecting any two of atmospheric pressure, boost pressure, and suction pipe negative pressure, special means are not required, the structure is simplified, and the pressure is kept almost constant. Since the difference is obtained, the operation of the actuator 13 is also consistently favorable.
