摘要： A creep-inhibiting device for use in an automotive vehicle equipped with an engine and a transmission mechanism coupled in series to a fluid coupling and having a frictionally engaging element. The device includes engine load sensor means for producing a signal fluid having a pressure representative of engine load, control means interposed between the frictionally engaging element and an operating fluid source, and a fluid line for delivering the signal fluid from the engine load sensor means to the control means. The control means is adapted to control the power transmission capacity of the frictionally engaging element within a range from substantially zero to a predetermined value in dependence on the signal fluid pressure supplied thereto, to inhibit creeping of the vehicle when the engine is in a no-load state. Selector valve means is arranged in the fluid line and adapted to assume a first position wherein it allows the signal fluid to flow in both directions from the engine load sensor means to the control means and vice versa when the pressure of the signal fluid is lower than a predetermined value, and to assume a second position wherein it allows the signal fluid to flow in a sole direction from the engine load sensor means to the control means when the pressure of the signal fluid is higher than the predetermined value.

摘要： A frictionally engaging device for power transmission of a vehicle, has a first pressure chamber defined in part by one side of a piston urging frictionally engaging elements into engagement with each other, and a second pressure chamber defined in part by the other side of the piston for accommodating the frictionally engaging elements. A hydraulic pressure control arrangement controls operating fluid pressure supplied to the first pressure chamber at least to a value higher than a first predetermined value which causes engagement of the frictionally engaging elements and to a second predetermined value lower than the first predetermined value, which inhibits creeping of the frictionally engaging elements. When the operating fluid pressure is lower than the second predetermined value, a first valve opens to allow escape of the operating fluid from the second pressure chamber to the first pressure chamber. When the operating fluid pressure is at least lower than the first predetermined value, a second valve opens to permit flow of the operating fluid from the first pressure chamber to the second pressure chamber, to thereby cool the frictionally engaging elements.

摘要： A direct-coupling controller for a torque converter direct-coupling clutch in an automatic transmission. The controller includes a pilot oil pressure operated timing valve which interconnects the hydraulic cylinders of at least two of the hydraulically operated friction elements of the transmission to the hydraulic-cylinder of the direct-coupling clutch. The timing valve has two positions, a first where one of the friction elements is connected to the clutch and a second where the other is. Structure can be provided to delay movement of the timing valve spool member for a predetermined time. Additionally, a reduction valve can be interposed between the timing valve and the clutch to keep the oil pressure to the clutch at a predetermined level. A vehicle speed response valve can also be interposed between the timing valve and the clutch in parallel with the reduction valve to bypass the reduction valve when the vehicle speed exceeds a predetermined value.

摘要： In a transmission for an automotive vehicle, a control system for a direct-coupling mechanism for mechanically engaging input and output members of a hydraulic power transmission. An operating fluid pressure regulator controls operating fluid pressure applied to a hydraulically operating portion of the direct-coupling mechanism, and the direct-coupling mechanism applies an engaging force corresponding to the operating fluid pressure thus controlled to the input and output members. A vehicle speed sensor detects the speed of the vehicle, and a slip sensor detects the value of a predetermined parameter indicative of an amount of relative slip between the input and output members. When the detected vehicle speed falls between a first predetermined value and a second predetermined value larger than the first predetermined value and at the same time the detected value of the predetermined parameter is outside a predetermined range, a control device causes the operating fluid pressure regulator to vary the magnitude of the operating fluid pressure so that the predetermined parameter falls within the predetermined range.

摘要： An estimation unit estimates the amount of power consumption for each unit period of time. A rechargeable battery control unit controls the rechargeable battery such that an exceeding amount of power worth the amount of power exceeding a target amount of power during a unit period of time is charged into the battery, and power is discharged from the battery during a time zone wherein the target amount of power is exceeded, on the basis of the result of the estimation. When the battery needs to be charged in excess of the upper-limit value, the control unit charges the battery up to the upper-limit value during a time zone wherein the amount of power consumption estimated is light, and the amount of power that exceeds the upper-limit value is charged during a time zone that is close to the time zone wherein the target amount of power is exceeded.
