、くなるとともに（ｇ号ｄも信号ｅＫ沿って増大する。The operation of the above conventional device will be explained with reference to FIG. First, when the load of the torque converter is in the off state (N range), that is, in the idle state, if the rotation speed of the internal combustion engine 1 falls below the target rotation speed for some reason, that is, the signal a
If the rotational speed deviation signal C decreases with respect to the signal S, a rotational speed deviation signal C is generated, and the integrator 7 integrates this signal C. Therefore, the signal g increases, and since the signal ri is zero, the signal e also increases,
The pupil deviation signal f increases. Therefore, the drive 513 increases the opening degree of the throttle valve 2 via the actuator 3, and the rotational speed of the internal combustion engine 1 increases to reach the target rotational speed.
, (g and d also increase along with the signal eK).

ように制御される。Conversely, even when the actual rotational speed is higher than the target rotational speed, the actual rotational speed is controlled to be equal to the target rotational speed using the same 11-operation VC.

等しくなるように制御される。Next, a case in which the load state changes from off (N range) to on (1) VC and then off again will be explained with reference to FIG. 1. Time '11. When the load state changes from off to on VC, the load detector 8 detects this 2,
In response to this detection signal, the load corrector 9 outputs a load detection wrinkle signal hl having a predetermined value. Father, internal combustion engine 1 due to increased load
Since the actual rotational speed of the engine decreases, the signal a decreases and the signal g increases. Therefore, the target operation signal signal +jC increases by 1.2,
The opening IJl of the throttle valve 2 increases. This change in the opening degree of the throttle valve 2 corresponds to the predetermined negative speed correction 1tVC, and the fluctuation in the actual rotational speed due to changes in the load condition is slight. Thereafter, the actual rotational speed is controlled to be equal to the target rotational speed by the function of the integrator 7, similarly to when the load is off. Next, when the load state changes from on to off at time Tl, the load detector 8 detects this change, so the load correction amount signal becomes zero, the target operation signal e decreases, and the opening degree of the throttle valve 2 changes. becomes smaller. Although the actual rotational speed increases due to the decrease in load, the opening degree of the throttle valve 2 is reduced as described above, so that the actual rotational speed is controlled to be equal to the target rotational speed.

安定となった。As described above, in the conventional device, when the load of the torque converter is on, a certain load correction amount is added to control the throttle valve 2, that is, the intake air amount, and the internal combustion engine 1
Although the fluctuation of the 0 rotation speed is suppressed, the correction is made assuming that the torque converter load 'k is constant, and in reality the torque converter load, that is, the load of the internal combustion engine 1, fluctuates. Although the optimal correction could not be made, the rotation fluctuations during torque converter shifting were not sufficiently suppressed, and the internal combustion engine rotation became unstable when idling.

目的とする。The present invention aims to eliminate the above-mentioned drawbacks of the prior art.
By changing the load correction amount according to the actual rotation speed or target rotation speed of the internal combustion engine, it reduces the drop or rise in rotation when shifting the torque converter.
It is an object of the present invention to provide a rotational speed control device for an engine in a vehicle equipped with a torque converter, which can thereby improve rotational stability during shifting and idling.

Generally, the vehicle is stopped, but the internal combustion engine 1 is controlled to an appropriate rotation speed depending on the cooling water temperature, the presence or absence of a cooler load, the presence or absence of an electrical load, etc. may be fast or slow. In this idle state, the load detector 8 does not detect the load, and the load detector 11/14 does not output the load correction signal i1. When the load is shifted from OFF to ON, that is, from the N range to the 1 range, the engine starts at a low speed, and in this case, when the rotation speed of the internal combustion engine 1 is high, the torque The negative load on the converter, that is, the negative load on the internal combustion engine increases, and when the rotation speed of the internal combustion engine 1 is low, the load decreases.The load compensators 1 and 4 are connected to the load detector 8.
When the internal combustion engine 10 rotation speed is high, it outputs a large load correction signal. The position signal e also increases, the throttle valve 2#i is opened wide, and the amount of intake air increases.Therefore, entanglement of the rotating needle of the internal combustion engine 1 due to an increase in load is suppressed.For example, due to a cooler load, γ・1 dollar If the load is turned on when the rotational speed is high, the load correction amount will be large, so there will be little fluctuation in the rotational speed.On the other hand, if the idle rotational speed is low and the load is turned on, the The rotation correction Ii' becomes small, but in this case the load is also small, so the drop in rotational speed is suppressed.Of course, when fln'r is turned from on to off, the rotation ls+ will increase at VC. and 1
Even in the case of -, the signal corresponding to the magnitude of 14 ri becomes zero, so the increase in the number of rotations is well suppressed.

Therefore, it is possible to improve the rotational stability during shifting, and also to improve the rotational stability during idling.
