ることなく増大して機関回転速度も増大する。 The operation when shifting up from 2nd speed to 3rd speed will be explained as an example. In the second gear, the limit switch 2 is in the closed state, but as the shift lever is removed from the second gear position and moved to the neutral position by the shift up operation, the limit switch 2 is in the open state. The signal from the limit switch 2 is sent to the electronic control section 8, so the electronic control section 8 controls the shift lever to 2.
The time t 1 at which the vehicle is removed from the speed position is detected. The electronic control unit 8 stores data corresponding to the graph in FIG. 2 in advance, and detects the vehicle speed at time t1, for example, vehicle speed A1 , from the vehicle speed sensor 9 , and determines the vehicle speed A1 at the third gear.
Find the engine rotation speed B 1 corresponding to . In this way, an electrical signal corresponding to the engine rotational speed B1 is sent to the holding timer 13, and is held at the output terminal of the holding timer 13 for a predetermined time T, for example, 2 seconds. As a result, the shaft of the servo motor 15 rotates, and the holding lever 15 is held at a position corresponding to the engine rotational speed B1 . Therefore, the lever 19 comes into contact with the holding lever 15, restricting the return of the throttle valve 17, and the supply of a predetermined amount of air-fuel mixture is ensured even though the accelerator pedal is released, so that the vehicle speed remains constant for a predetermined time T. is vehicle speed
A is prevented from falling below 1 . Since the shift lever is moved to the third speed position within this predetermined time T, the vehicle is smoothly accelerated without deceleration after the clutch is engaged. Note that the holding lever 15 is a throttle valve 17.
Since the opening degree of the throttle valve 17 is only maintained at the minimum opening degree by limiting the return of Engine speed also increases.

る。 The engine rotation speed to obtain the same vehicle speed differs depending on the shift position, so if the minimum opening of the throttle valve at the time of upshifting is fixed regardless of the type of upshifting, the engine rotational speed will vary depending on the type of upshifting. If it is too high or too low, an impact noise may occur when the clutch is engaged, or drivability may deteriorate. According to the present invention, the minimum opening degree of the throttle valve is such that for a predetermined period of time after the transmission is set to neutral for a gear shift operation, the vehicle speed before the gear shift operation is maintained at a shift position one gear higher than the shift position before the gear shift operation. The opening is maintained at an opening that provides an engine rotational speed corresponding to . As a result, the drop in engine speed during gear shifting is suppressed, making it possible to avoid deceleration of the vehicle, and the engine speed corresponding to the type of upshift can be obtained when the clutch is engaged, improving drivability and reducing impact noise. can be suppressed.
