摘要
This invention the torque converter lockup clutch of the automatic transmission had (2), the fluid type torque converter one for (1) it regards the fluid pressure control system. The converter pressure valve (WDV), the torque converter (1) supply pressure (p_WD_zu) it is used in order to control, the converter clutch valve (WKV), supply pressure of the torque converter lockup clutch (p_WK_zu) it is provided in order to control. That valve disk (WDV_S and WKV_S), it can operate pilot pressure (p_VS) with system pressure (p_sys) by at least. The converter clutch valve (WKV) the valve disk (WKV_S), in order at least the aforementioned torque converter (1) supply pressure (p_WD_zu) or the aforementioned torque converter lockup clutch (2) supply pressure (p_WK_zu) for each of them the aforementioned torque converter (1) to extend to all the operating space and specified pressure level (p_0) to be higher, the torque converter lockup clutch (2), the operating surface (15) to operate when releasing the aforementioned torque converter (1) counterflow pressure (p_WD_ab) by, the aforementioned torque converter lockup clutch (2) when concluding, the aforementioned torque converter lockup clutch (2) supply pressure (The operating surface (15) it operates p_WD_zu) by.
