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 (PTh) 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 (PTh). 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 (PTh).

摘要： A multi-speed transmission with hydraulically actuated shift rods, wherein an actuating pressure (p_B) is applicable by a valve device (15) and shuttle valves (2C to 6D) to piston chambers (2A to 6B) of pistons (2 to 6), the actuating pressure being adjustable by valves (16, 17). The piston chambers (2A to 6B) can be brought into operative connection with a low-pressure region (52) by the shuttle valves (2C to 6D) and a prefilling valve (32, 33) or by the shuttle valves (2C to 6D), the valve device (15), and the valves (16, 17). Each of the shuttle valves (2C to 6D) has a spring assembly (2E to 6F), by which the shuttle valves (2C to 6D) are held below a pressure threshold of the actuating pressure (p_B) in an operating state that connects the piston chambers (2A to 6B) to the low-pressure region (52) by the prefilling valve (32, 33).

摘要： Method for controlling the transfer of torque of a force-fitting shift element (K0), which can be closed by a closing pressure acting on a piston (K), whereas, in order to control the closing pressure, a control valve (V) is configured, depending on a control signal of a control unit (ECU), through the setting of the valve lift (V_s), to transmit the system pressure (p_sys) of a hydraulic circuit (K1) to the piston (K), or to reduce it as needed, whereas, upon the presence of a closing request at the shift element (K0) and a prevailing system pressure (p_sys) of the hydraulic circuit (K1) above a threshold value for the system pressure (p_sys-t), the closing pressure is controlled at least temporarily in a manner different than when it is controlled upon the presence of a closing request at the shift element (K0) and a prevailing system pressure (p_sys) below the threshold value for the system pressure (p_sys-t).

摘要： Aspects of the present disclosure include methods of modifying a transmission valve body to increase a line pressure response in certain hydraulic shift control system configurations. In one example, a Daimler Chrysler 46RE or 47RE transmission valve body may be modified to have a higher and more rapid line pressure increase when the transmission is in fourth gear and when the torque converter clutch (TCC) is engaged. Aspects of the present disclosure also include methods of modifying a transmission valve body to allow TCC engagement in any gear. Aspects of the present disclosure also include replacement valve bodies, as well as kits for modifying a 46RE or 47RE valve body to perform like a 48RE valve body.
