PURPOSE:To reduce a shock, by making an engine speed and a clutch speed almost equal to each other until a half-clutch starting point and, on and after the half-clutch starting point, increasing a feed quantity of fuel to an engine, when a clutch is engaged as shift motions are over. CONSTITUTION:When a clutch is engaged after shift motion, an engine speed is controlled so as to make it equal to a...

PURPOSE:To improve a starting characteristic as well as to eliminate a grating noise of gears, by disengaging the existing gear when a car speed goes down to below the specified value, while controlling an engine speed so as to become a synchronous speed, engaging a starting gear, and under this condition, making a clutch stand by without being engaged. CONSTITUTION:When a car speed comes to the s...

A system for controlling an electromagnetic clutch has a reference valve generator which produces clutch-engaging and clutch-disengaging engine speed signals in a low vehicle speed range. Engine speed is compared with the engine speed signals by a comparator. The clutch is engaged at a higher engine speed than a clutch disengaging speed and disengaged at a lower engine speed than a clutch engaging...

PURPOSE:To prevent the reduction of the number of revolution in automatic speed change and smooth speed change by controlling the operation of an exhaust brake so as to be prohibited when the exhaust brakes is operated during the speed change operation when the speed change of an automatic transmission is not completed. CONSTITUTION:In order to obtain a prescribed number of revolution in speed cha...

A transmission control system for a motor vehicle provided with a clutch and a continuously variable transmission. The transmission has a spool valve (40) controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. The transmitted torque (TD) in the transmission system is detected and a desired clutch torque (TC) dependent on the transmitted tor...

PURPOSE:To connect the clutch quickly thus to shorten the time required for speed change operation by temporarily opening the exhaust valve until start of returning stroke upon finish of going stroke of actuator thereby discharging the excessive pressure of actuator during gear change. CONSTITUTION:A solenoid feed valve 7 is opened to cause go stroke of actuator 1 thus to disconnect the clutch thr...

The output of the engine (6) is reduced by the slip control as a degree of slippage of the driven wheels (4,5) on pavement gets larger. Upon the slip control, the shift control of the automatic transmission (8) is brought into a state in which the speed stages are unlikely to be shifted.

PURPOSE:To make stable action achieved for a long period by applying a regenerating process to make the forward end of a needle-like chip to be in the form of a facet in a first process, and applying a process of maintaining the form of the facet in a second process. CONSTITUTION:The forward end of a needle-like chip having a curvature is regenerated to be a facet in a first process, where the ele...

PURPOSE:To weld a welding piece easily on a substrate excellently by a method wherein a tool horn having characteristics is used, the welding piece on the substrate is pushed by the tool horn, torsional vibrations are applied, the energy of a radiating surface is transmitted over the contact surfaces of the welding piece and the substrate, heat is generated and the contact surfaces of the welding ...

PURPOSE:To minimize a time-lag in the change gear operation performed on the way of a steeply sloping road and the like by supplying an air cylinder with air by a fixed time earlier before a shift head reaches its neutral position in the select operation followed by the shift operation of gear position. CONSTITUTION:Various conditions of a running vehicle, such as shift signal 9, engine speed 13, ...

PURPOSE:To increase a clutch cutting off engine speed higher in a sudden braking to prevent an engine stop, by cutting off the clutch in a preestimate considering the engine speed and its negative variation rate. CONSTITUTION:An engine speed detecting means 15 is furnished at the crank pulley portion of an engine 1, and, a clutch cutting switch 16 to detect the cutting condition of the clutch 2 an...

PURPOSE:To increase reliability and lengthen life by pouring gelled electrolyte in a plurality of plate groups which are inserted into the small cell, and making the electrolyte contact with the plate groups through the upper part of a reinforcing partition. CONSTITUTION:Each plate group 12 is inserted into each cell formed by dividing a container 1 into a plurality of blocks with reinforcing part...

PURPOSE:To realize bead setting with high accuracy without any offset of a bead relative to a main drum, by intermediately providing a forced reciprocation mechanism for shifting between a condition where a front end face of a bead-retaining ring is on the forward side of a front edge of a bead-receiving ring and a condition where the front end face is on the rear side of the front edge. CONSTITUT...

A motion detecting system is disclosed where the signal from the transducer is analysed in a manner to distinguish between actual motion indicative of an intruder, typical noise expected for the area under supervision and the transducer and a signal which indicates a trouble condition (circuit failure, masking, or other trouble condition having a known signal signature). The system samples the sig...
