給機の回転数も上昇せず特に問題は見られなかった。BACKGROUND OF THE INVENTION The hydraulic pressure of lubricating oil for a supercharger according to the conventional technique disclosed in Japanese Patent Application Laid-Open No. 63-248923 depends only on the engine oil pressure, and the oil pressure is almost determined by the engine rotational speed. Furthermore, with the original supercharger, the supercharger's rotational speed did not increase unless the engine rotational speed increased, so no particular problem was observed.

る。[Problem to be Solved by the Invention] In the case of a self-rotating supercharger such as a turbocharger with a rotating electric machine, the above-mentioned conventional technology allows the rotational speed of the supercharger to be increased regardless of the engine rotational speed. Therefore, there is a risk of insufficient oil pressure. The present invention makes it possible to maintain a hydraulic pressure always higher than a target value with respect to the rotational speed of a supercharger, and aims to improve the reliability of a supercharger bearing.

制御する事を可能とした。[Means for Solving the Problems] In order to achieve the above object, a hydraulic system exclusively for the supercharger is provided, making it possible to control the hydraulic pressure based on the rotational speed of the supercharger.

あるかいなかを判別する。[Operation] A signal of the rotation speed of the supercharger is sent by a rotation speed detection sensor installed in the turbocharger, and a pressure sensor installed at the turbocharger lubricating oil inlet and a pressure sensor for detecting engine oil pressure. A hydraulic signal is sent to the controller. The controller determines whether the pressure is higher than the set pressure for the rotation speed.

部の信頼性が向上される。If the pressure is below the set pressure, a hydraulic pump operation command signal is sent from the controller to the hydraulic pump installed near the supercharger lubricating oil inlet, and the hydraulic pump is operated until the set pressure is reached. This makes it possible to secure an oil film on the bearing of the supercharger, thereby eliminating seizure of the bearing and improving the reliability of the bearing.

サ７より信号が該コントローラー４に送られる。The rotational speed of the supercharger is detected from the supercharger rotational speed detection sensor 3 or the input/output of the rotating electric machine section 2, and a signal is sent to the controller 4. Further, signals are sent to the controller 4 from a pressure sensor 6 attached to the supercharger lubricating oil inlet 5 and a pressure sensor 7 for detecting engine oil pressure.

防止する。In the controller 4, it is determined whether the lubricating oil pressure is higher than a set pressure with respect to the rotational speed of the supercharger. If the controller 4 determines that the pressure is below the set pressure, it sends a signal to operate a hydraulic pump 8 dedicated to the supercharger, which is provided upstream of the pressure sensor 6 attached to the supercharger lubricating oil inlet 5. As a result, the hydraulic pump 8 is activated and the oil pressure begins to rise. Moreover, since the pump 8 is operating at that time, almost no oil flows from the bypass 13. When the output of the pressure sensor 6 exceeds a set value for the rotational speed of the supercharger, the operation command signal from the controller 4 to the hydraulic pump 8 is stopped, and the operation of the hydraulic pump 8 is also stopped. Since the passage on the hydraulic pump 8 side is constricted, oil flows from the bypass 13 to the supercharger and introduces engine oil pressure to prevent unnecessary operation of the hydraulic pump 8.

This can improve the reliability of the bearing.
