ト１００の出力が′Ｌ′となってこｒ。Next, when the resume switch SXX2 is closed, the timer circuit 90 is activated.
'? The timer of the timer circuit 90 of the i90 operates. The closing time of this resume switch SW2 is 1iT memorized (
If the time is shorter than the setting time of the T circuit 90, the above-mentioned Mi
An operation is performed to return the Llj speed to the speed before release. Step 1: If the closing time is greater than or equal to the set time, the acceleration signal generating circuit 90 generates an acceleration signal. This acceleration signal (a low level signal) is connected to the base of transistor T1 and capacitor C2 via diodes D2 and D3. Therefore, transistor T1 is turned off and FET Fl is turned on. , FET
A reference voltage Vr is applied to the base of F2. That is, the source turtle of FETF2 (J.VM is VM=■r
7, the second comparator C Ni compares the reference voltage Vr and the divided voltage Vx. At this time, as mentioned above,
Vx) Vr, the output of the comparator CM is set to 'H' and the control solenoid SL of the actuator 50 is turned on, increasing the throttle opening and increasing the amount of torque. This acceleration is caused by the resume switch SW2
2, and when the desired speed is reached, the resume switch SW2 is opened and the transistor T1 is closed.
By turning from OFF to ON, a second signal is obtained, and the speed is recorded again. When the cancel switch SVV3 is closed during the above speed increasing operation, the flip-flop circuit 70 is activated.
As the constant speed running is canceled, the output of the all-circuit gate 100 becomes 'L'.

Even if W2 is closed and returns to normal, if you close cancel switch SW3, constant speed running will be canceled.
If the acceleration does not stop, the danger of 1 can be prevented.0
