摘要： During shift change, a discrimination is made as to a load, a quantity of residual hydraulic oil in respective shift change clutches (F, R, 1 to 4) and a state of shift change which has been effected from what speed stage to what speed stage so that a pattern of electrical commands to be issued to pressure control valves for required shift change clutches is variably controlled depending on results derived from the above discrimination. Thus, smooth shift change can always be achieved regardless of running conditions. Electrical commands to be fed to the respective pressure control valves are compared with electrical currents outputted from drive circuits and outputs from clutch pressure detecting means for each clutch, whereby an abnormality is detected with the relevant clutch based on results derived from the comparison. Once an abnormality is detected, an adequate disposal for processing the abnormality is executed so as to reliably prevent double engagement from taking place with clutches.

摘要： When a press or like machine is centrally controlled, many sensors are used for detecting the conditions of various portions of the machine and many actuators are used for controlling the conditions of various portions of the machine. The invention provides a device for detecting the position of broken line in a series controller wherein peripheral processing devices indirectly control the sensors and the actuators, and these peripheral processing devices are connected in series via signal lines in an annular manner via a central processing unit or in a serial manner relative to the central processing unit, such that position of breakage on the signal line can be detected. Therefore, when breakage develops on the signal line and no signal is transmitted to the peripheral processing device directly after the broken line, the peripheral processing device produces a line breakage signal. Upon receiving the line breakage signal from a controller of a preceding stage, the peripheral processing devices in the subsequent stages add the broken line position data of broken line signal one by one successively. Thus, as the line breakage signal is input to the central processing unit, the calculation is carried out in a reversed manner from the added value of broken line position data of line breakage signal that is input, and a position of broken line is detected.

摘要： The present invention is concerned with a transmission constructed in the two-staged structure including main speed changing units (1st, 2nd) and auxiliary speed changing units (H, L) which are provided with clutches (H, L, 1st, 2nd) which in turn are individually connected to electronic type pressure control valves (21 to 24) so as to enable the respective clutches to be controlled separately. When it is found that pressurized hydraulic oil delivered from a hydraulic pump has a shortage in amount at the time of starting of forward movement of a vehicle, feeding of hydraulic oil to the clutches (H, L) on the main speed changing unit side and the clutches (1st, 2nd) on the auxiliary speed changing unit side is effected with a certain time difference kept therebetween in order to suppress fluctuation in filling time due to reduction of an amount of hydraulic oil delivered from the hydraulic pump.

摘要： An automatic speed changing apparatus for a vehicle for automatically controlling speed change in connection with movement of the vehicle, wherein a hold switch (180) for making a designation as to whether a hold processing, i.e., a processing of automatically holding the gear position (speed stage) of a transmission (160) selected at this time point should be executed or not is provided for a controller (130) for the automatic transmission apparatus independently of actuating levers (111, 112) in the form of a select lever or the like so that the controller executes the hold processing in response to actuation of a hold switch. In case where movement of the vehicle is shifted from forward movement to rearward movement and vice versa after the hold switch is actuated, the transmission is once forcibly shifted to a second speed stage (representative of a shift change) when the vehicle starts its movement, and thereafter when the vehicle speed is increased to reach a required speed stage which has been held, the required speed stage is automatically maintained as a result of the hold processing. With this construction, the automatic speed changing apparatus permits a work to be smoothly conducted at a high efficiency for a construction machine such as a wheel loader or the like vehicle.

摘要： An operation control device is disclosed. According to a drive command value generated depending on the manipulated amount of a plurality of operating means (11, 12, 13, 14, 15, 16), the operation control device controls the drive amount of actuators (BMS, AMS, BKS, LDM, RDM, TNM) associated with the operated actuator. In the drive amount control, the operation control device changes a ratio of the manipulated amount and the drive amount command value by work accuracy flow rate data (41), weights the drive command values based on the same manipulated values of said operating means by priority mode weight data (42), and/or controls the timing of supply of the drive energy from at least two separate energy sources (FFP, RP) as a drive energy source for the respective actuators, and the supply amount of the drive energy, under control of pump utilization data (43) and pump swash plate control data (44). Every time the operating means are operated, these pieces of the control data are properly determined through proper operations (including the look-up table processing) according to the operations of the operating means, the selections of the work accuracy mode select switch (21) and the priority mode select switch (22).
