の変速制御装置。 A friction clutch connected to the engine, a clutch actuator that operates the friction clutch in a direction of disconnecting or connecting by introducing or discharging fluid, and a fluid supply means for supplying fluid to operate the clutch actuator. , a gear type transmission connected to the friction clutch, a gear position switching means for switching the gear position of the gear type transmission, and a fluid servo brake that generates a braking force using fluid supplied from the fluid supply means. , an air switch provided in the piping from the fluid supply means to the fluid servo brake; an alarm means activated by the air switch; an operation control function that controls the operation of the gear position switching means;
Then, the increase/decrease value of the accelerator pseudo signal voltage value before the engine speed peaks at the time of starting is determined based on the target engine speed and the actual engine speed, and the accelerator pseudo signal voltage is determined based on the increase/decrease value. An engine speed increase function that brings the engine speed closer to the target engine speed without unnecessary increases in engine speed, and the accelerator opening when the engine speed reaches its peak when starting is below a preset value. When this occurs, a fine movement control process is performed to cause the vehicle to move slightly, and when the accelerator opening degree when the engine speed reaches its peak exceeds the set value, a normal control process is performed to start the vehicle normally. When performing the state switching function and normal control processing at start, the difference between the current accelerator opening voltage value corresponding to the actual accelerator opening degree and the accelerator pseudo signal voltage value is determined, and the value of this difference is used as the voltage corresponding to the current accelerator opening degree. The accelerator pseudo signal voltage is determined by the normal accelerator pseudo signal voltage output function that subtracts the subtracted value from the value and outputs the subtracted value as the accelerator pseudo signal voltage value, and the engine rotation speed increase function that uses the accelerator pseudo signal voltage in the fine movement control processing at the time of starting. A fine accelerator pseudo signal output function that is set in the same procedure as the means and outputs the output timing longer than the accelerator pseudo signal voltage determined by the engine speed increase function, and the accelerator opening at the peak of the engine speed at the time of starting. A target clutch stroke setting function that sets a target clutch stroke at the peak of engine speed based on the clutch stroke, and a set time when the engine speed and clutch speed are synchronized when starting or in the case of a slight start. A clutch connection function that connects the friction clutch after it is loosely connected during duty control, and a lower limit value is set for the engine speed value when determining the engine speed value in the micro-movement control process and normal control process when starting. What is claimed is: 1. A shift control device for an automatic transmission device, comprising: a control device having an engine rotation speed determination function, and an accelerator pseudo signal voltage phase release function that gradually releases the accelerator pseudo signal voltage at the end of starting.
