摘要： In a vehicle on which a torque converter (4) having a lock-up clutch (3) is mounted between an engine (1) and a transmission (6), a meet point learning controller (12c) is provided to perform learning control for obtaining a learning value (L) based on information on a meet point at which the lock-up clutch (3) starts torque transmission. The meet point learning controller (12c) estimates a LU transmission torque based on a difference between an engine torque signal value (Te) and a torque converter transmission torque (τ×Ne 2 ) when the lock-up clutch (3) moves from a non-engaged state to an engaged state during traveling of the vehicle, and uses, as the meet point information, a meet point detection pressure (LUPRSEDGE) at a time when the LU transmission torque estimated value is determined to have entered an upward trend.

摘要： A hydraulic control device includes: a mechanical oil pump (O/P) that is driven by a motor/generator (M/G) and that generates a first hydraulic pressure (P1); an electric oil pump (M/O/P) that is driven by a sub-motor (S/M) and that generates a second hydraulic pressure (P2); and a controller (10). When a demanded drive force from a driver is generated while in a low-vehicle-speed region which is lower than a first vehicle speed (V1) at which the output of the mechanical oil pump (O/P) becomes unstable, the controller (10) controls the electric oil pump (M/O/P) such that the second hydraulic pressure (P2) becomes larger than a compensative hydraulic pressure (P±) found by subtracting the first hydraulic pressure (P1) from a necessary hydraulic pressure (Pne) determined in accordance with the demanded drive force.

摘要： The present invention is configured such that: in a stopped state of an electric oil pump (M/O/P), control of the electric oil pump (M/O/P) is started such that, when a driver has the intention of demanding drive force, a discharge pressure takes on a target hydraulic pressure (P Th ) determined in accordance with the demanded drive force from the driver; and a pressure regulation target value of a line pressure regulation valve (101) is set to a value that is higher than or equal to the target hydraulic pressure (P Th ). Thus, it is possible to provide a vehicular hydraulic control device capable of suppressing hunting in line pressure (PL) when the line pressure (PL) is regulated so as to take on the target hydraulic pressure (P Th ).

摘要： In a hybrid power system, when a change-speed stage selected in one of gear-shift mechanisms for first and second drive trains is switched over to another change-speed stage in the other gear-shift mechanism, deceleration in rotation speed of an engine detected by a rotation speed sensor is compared with a preset upper limit. When the deceleration in rotation speed of the engine exceeds the upper limit, the motor-generator in drive connection with an input shaft of the second drive train is activated as an electric motor to cause load torque canceling or offsetting input torque applied to the input shaft of the other gear-shift mechanism from the engine, and engagement of the change-speed stage in the other gear-shift mechanism is released after the occurrence of the load torque.

摘要： There is provided an oil pressure control device for a belt-type continuously variable transmission which includes two pulleys and a belt provided between the two pulleys and wound around the two pulleys to transmit motive power, wherein each of the two pulleys has a movable sheave which moves by oil pressure supplied to a hydraulic chamber, wherein the oil pressure control device calculates a request torque according to a running state, wherein when calculating the oil pressure which is supplied to the hydraulic chamber of the movable sheave on the basis of the request torque, the oil pressure control device reduces the request torque if the request torque is greater by a predetermined value or more than an actual input torque which is inputted to the belt-type continuously variable transmission. Accordingly, it is possible to provide an oil pressure control device for a belt-type continuously variable transmission with which undesirable vibration can be avoided by means of stable speed-ratio control.
