Conventionally, a method has been adopted in which the gears are changed manually via the gearshift lever, and with this method, it is necessary to operate two types of levers, the main and the sub-lever, in order to change the desired gear. However, there is a problem in that it takes time for the gears of the sub-transmission mechanism to synchronize. Note that the gears of the auxiliary transmission mechanism are changed based on the vehicle speed or engine speed without using the auxiliary transmission lever.
A system described in Japanese Patent Application Laid-Open No. 55-76245 is known, but even this system does not take into consideration the synchronization of the gears of the sub-transmission mechanism.

制御装置の作用を以下に説明する。
FIG. 1 shows an embodiment of a control device for an auxiliary transmission mechanism according to the present invention, and in the same figure, reference numeral 1 indicates a shifter which outputs an operation command for operating the auxiliary transmission mechanism provided near the shift knob. It is a lever switch, and the switch 1 is turned "ON" when operated and "OFF" when left unattended. Also, 2 is a clutch pedal operation detection switch that outputs an "ON" signal when the clutch pedal is depressed, 3 is a vehicle speed sensor that detects the vehicle speed, and 4 is a vacuum switch 6.
This is a detection circuit that detects the energization state of the vacuum switch 6, and when the solenoid of the vacuum switch 6 is energized, it is at a high level (hereinafter referred to as "H"), and when it is not energized, it is at a low level (hereinafter referred to as "L"). Outputs the signal. That is, the detection circuit 4 is configured as a gear ratio sensor that detects the gear ratio state of the auxiliary transmission mechanism based on the energization state of the vacuum switch 6. Further, numeral 5 denotes a control circuit that takes in signals from various sensors, and is composed of a microcomputer, etc., and performs processing as shown in FIG. That is, the outputs of the switches 1 and 2 and the sensors 3 and 4 are monitored, and when the vehicle speed is lower than the set vehicle speed, the detection circuit 4
A gear ratio change signal (“L” signal) is output to the vacuum switch 6 on the condition that a small gear ratio detection signal is generated by the detection of the gear ratio and a detection signal of the clutch pedal operation detection switch 2 is generated, and the vehicle speed changes to the set vehicle speed. When the signal is exceeded, the detection circuit 4 outputs the signal of the large gear ratio change signal and the small gear ratio change signal (“H”) on the condition that an operation command of the shift lever switch 1 and a detection signal of the clutch pedal operation detection switch 2 are generated. A switching signal for setting a gear ratio different from the detected content is selected and output to the vacuum switch 6. Further, 6 is a vacuum switch for switching the negative pressure circuit, and when the solenoid constituting the vacuum switch is energized, the circuit between the negative pressure source 7 and the diaphragm 9 is opened, and the circuit to the air filter 8 is closed. Further, when the solenoid is in a non-energized state, the circuit between the air filter 8 (outside air) and the diaphragm 9 is opened, and the circuit to the negative pressure source 7 is closed. The diaphragm 9 moves the auxiliary transmission switching sleeve 11 back and forth via the lever 10 depending on the presence or absence of negative pressure from the negative pressure source 7, thereby switching the meshing of the auxiliary transmission gear. That is, vacuum switch 6, negative pressure source 7, air filter 8, diaphragm 9, lever 1
0. The switching sleeve 11 is configured as gear switching means. Next, the operation of the control device for the auxiliary transmission mechanism having the above configuration will be explained below.

るように構成されている。 First, when the vehicle speed is below the set vehicle speed, when the clutch pedal is operated and the clutch pedal switch 2 is in the "ON" state and the diaphragm 9 is in the energized state, the output signal from the control circuit 5 changes from "H" to "L". ”, and the vacuum switch 6 changes from the energized state to the de-energized state.
As a result, the negative pressure that was acting on the diaphragm 9 is released to the atmosphere via the vacuum switch 6 and the air filter 8, and the balance spring in the diaphragm 9 moves the lever 10 to the sleeve 11.
moves, and the gear engagement is changed. (In this case, the gear train combination will be from a small gear ratio to a large gear ratio.) In this operation, when the clutch pedal is operated at low speed or when stopped, the gear train combination of the sub-transmission mechanism will always be set to the higher gear ratio. It is configured to

られる。 Next, when the vehicle speed exceeds the set vehicle speed and the clutch pedal switch 2 and shift lever switch 1 are simultaneously turned on, the output signal from the control circuit 5 is inverted. That is, the electrical signal 20 of the vacuum switch 6 is "H"
(“L”), the output signal of the control circuit is “L”
(“H”). As a result, the negative pressure supplied to the diaphragm 9 is released to the atmosphere via the air filter 8 (negative pressure is supplied to the diaphragm 9 via the vacuum switch 6). Therefore, the gear switching sleeve 11 of the sub-transmission mechanism is driven via the lever 10, and the meshing is switched to a gear train combination with a large gear ratio (to a gear train combination with a small gear ratio).
この作動は運転者がシフトレバースイツチ１の

この切り換えはクラツチペダルを操作した時のみ
作動するように構成されているのでギヤ切り換え
時の同期を無理なく行なわせることができる。 This operation allows the driver to change gears in the auxiliary transmission mechanism by operating shift lever switch 1, and since this switching is configured to only operate when the clutch pedal is operated, it is impossible to synchronize gear changes. You can do it without any problems.
