速変速段は第３速となる。In FIG. 1, the speed change control device of the automatic transmission has an electromagnetic speed change valve, and the gear device and hydraulic control device of the automatic transmission are similar to the conventional device described in, for example, ￥f Application No. 53-92528. It is the composition. The opening sensor 1 generates a voltage B1 related to the opening Al of the carburetor throttle valve, as shown in FIG. The carburetor throttle valve is continuously excited by the accelerator pedal of the advanced rfM, and the opening degree Al corresponds to the engine load. The output of the opening sensor l is sent to an adder 5 via a differentiator 2, a comparator 3, and a holding circuit 4. The 8 forces of the differentiator 2 correspond to the opening speed of the throttle valve and therefore to the rate of change of the engine load. The holding circuit 4 holds the output of the comparator 3 for a predetermined time, for example, 2 seconds. The output of the opening sensor 1 is also sent directly to the adder 5. The adder 5 functions as a correction means that generates a value obtained by correcting the detected value of the throttle valve opening degree by the detected value of the opening speed of the throttle valve, and combines the output of the opening sensor 1 and the output of the holding circuit 4. Add. Adder 5
and the output of the vehicle speed sensor 6 is sent to the computer 7,
The computer 7, as a gear determining means, determines the gear based on these signals, and according to this determination, the DC power source l is switched on.
The energizing current from O to the 1-2 speed change valve 3 and the 2-3 speed change valve 9 is controlled. The 1-2 speed change valve 8 and the 2-3 speed change valve 9 are electromagnetic valves operated by the computer 7, and include a friction engagement device for 1st speed, a friction engagement device for @22 speed, and a thick friction engagement device for 3rd speed. Controls the supply of line pressure to the engagement device. Since this speed change control device has two speed change valves, the 1-2 speed change valve 8 and the 2-3 speed change valve 9, the lowest speed change stage is the first speed, and the highest speed change speed is the third speed.
微分器２は開度センサｌの出力を微分する。Differentiator 2 differentiates the output of opening sensor l.

電圧Ｂ３を発生してコンピュータ７へ送る。Therefore, the opening speed A2 of the throttle valve and the output B2 of the differentiator 2
The relationship with is shown in FIG. Comparator 3 is
The signal sent from the differentiator 2 to the holding circuit 4 is controlled in relation to the sign of the output of the differentiator 2. That is, when the opening speed of the throttle valve (output voltage 82 of the differentiator 2) is negative, in other words, during deceleration, the output of the comparator 3 becomes zero. On the other hand, when the opening speed of the throttle valve is positive, in other words acceleration, the comparator 3 sends the output of the differentiator 2 to the holding circuit 4 as is. The holding circuit 4 holds the output signal of the differentiator 2 until the speed change valves 8 and 5 actually respond to this output signal. The adder 5 adds the output voltage of the holding circuit 4 and the output voltage of the opening sensor l and sends the result to the computer 7. Vehicle speed sensor 6 generates an output voltage B3 related to vehicle speed A3 and sends it to computer 7, as shown in FIG.

上へ移行する。When the vehicle is first in the state shown at point 16 in FIG.
Assume that the vehicle is being operated at 0 km/h and the throttle valve opening is 20%. Next, the operator suddenly depresses the accelerator pedal, and the throttle valve opens at 200%/S and opens at 30% (
Assume that the change occurs to point 17) in FIG. With conventional equipment,
Since point 17 is still in the third speed range as the highest gear, a downshift, that is, release of the highest gear, is not performed. In the embodiment of the present invention, 200%/S of the throttle valve
Due to the opening speed of the voltage of IV is changed from differentiator 2 to comparator 3
, and is sent to the adder 5 via the holding circuit 4, where the voltage 3■ corresponding to the throttle valve opening of 30% and the voltage IV from the differentiator 2 are added together. In this way, the voltage of 4V from the adder 5, that is, the throttle valve opening 4096 (5th
Since the voltage corresponding to point 18) in the figure is sent to the computer 7, the computer 7 selects the third gear as the highest gear.
In other words, by operating the 2-3 speed change valve 9, a downshift to the second speed is performed. Considering the time delay between when the accelerator pedal is depressed and when the automatic transmission responds, the holding circuit 4 holds the output of the differentiator 2 for a predetermined period of time, but as the vehicle speed increases, the output of the holding circuit 4 becomes Since it becomes zero, the state of the automatic transmission is the horizontal line 19 passing through point 17.

The engine load, that is, the higher the vehicle speed at the same throttle valve opening, the higher the value becomes, and the release of the highest gear is suppressed at high speeds. Furthermore, as can be seen from Fig. 5, the rate of increase in engine load at which the highest gear is released becomes higher when the engine load and therefore the throttle valve opening are lower at the same vehicle speed; release is suppressed when the engine load is low.
