摘要:
In an electronically controlled automatic transmission system including a gear transmission and a clutch, in which a target gear position is determined in accordance with map data for gear-shift control, it is discriminated whether or not the vehicle is in accelerating condition and necessary control for shifting up the transmission to the target gear position is carried out only when the vehicle is not in the accelerating state. Thus, when the driver presses hard on an accelerating member to accelerate the vehicle, a series operations for shifting up is not carried out, whereby the transmission is kept in its present gear position. The operation for shifting up can be carried out after the completion of the acceleration of the vehicle.

A remotely operated, direction switching proportional control device comprises a direction switching control valve which includes a hydraulic actuator, an electromagnetic pressure reducing valve interposed between a liquid chamber of the hydraulic actuator and a hydraulic power source and an electromagnetic open or closed valve interposed between the liquid chamber and a liquid tank. Both the pressure-reducing valve and the open or closed valve can be operated against an electromagnetic force for return movement. The device eliminates the requirement for a piston stroke detector and may be operated by a single electromagnetic coil.

One embodiment provides a reference current generation circuit. The circuit has first and second reference current generation circuits for generating first and second reference currents respectively, and a current output circuit for outputting a third reference current by adding the first and second reference currents. The first reference current generation circuit includes first and second current-voltage conversion circuits and a first current supply circuit. The first current supply circuit provides substantially equal amounts of current to the first and second current-voltage conversion circuits respectively. The second reference current generation circuit includes third to fifth current-voltage conversion circuits and a second current supply circuit. The second current supply circuit provides a current to the fourth current-voltage conversion circuit, divide and provide amounts of current substantially equal to that of the current provided to the fourth current-voltage conversion circuit, to the third and fifth current-voltage conversion circuits respectively.
