Abstract:
1. A signal processor for a joystick that controls a solenoid comprising: a joystick input device which controls a joystick voltage input value in response to an operating amount of a joystick from a neutral position, input means which outputs the average value of the joystick voltage input value read at every sampling time over a predetermined number of past occasions as a joystick voltage computation value, computation means which computes an output computation value set in response to the joystick voltage computation value, and operation start detecting means which detects an operation start when the joystick is pushed over from the neutral position, wherein the computation means increases the output computation value to a predetermined value in response to the joystick voltage compensation value and momentarily causes a predetermined maximum current corresponding to a threshold current value flowing through the solenoid when operation from the neutral position is detected to start.
