Abstract

PURPOSE:To improve the control accuracy and responsiveness at the time of the shift transfer by changing the control quantity of an engine when a shift lever is transferred and correcting the control quantity in response to the difference between the engine rotating speed and the turbine rotating speed of a torque converter. CONSTITUTION:The rotation difference between the engine rotating speed and the turbine rotating speed of a torque converter is detected by a rotation difference detecting means 102, and the shift lever transfer is detected by a shift lever transfer detecting means 101. At the time of this transfer detection, the control quantity of an engine 1 is changed by a predetermined quantity by a control quantity correcting means 103. The control quantity of the engine is corrected in response to the rotation difference between the engine rotating speed and the turbine rotating speed of the torque converter due to the shift lever transfer. Accordingly, the responsiveness is improved and the accurate control can be performed without being affected by the shift transfer.

(Prior art) Conventionally, for example, the opening degree of the throttle valve during idling operation of the engine is changed depending on when the hydraulic automatic transmission is in the driving range (D range) and when it is in the neutral range (N range). It is known that the control amount of the engine, such as the intake air amount, is changed at the time of shift change (see, for example, Japanese Utility Model Publication No. 51-37065). In such devices, for example, when switching the shift lever from N range to D range, the engine control amount is changed by detecting the shift lever switching signal, but at the moment of detection, the automatic transmission There is a delay in the connection between the turbine side of the torque converter and the axle, and there is a delay in the load on the turbine side acting on the pump side, so the load is not immediately applied to the engine, resulting in over-control and rotation. There is a problem that fluctuations occur and accurate control cannot be performed.

Therefore, it is known to correct the engine control amount according to the rotation difference between the engine and the turbine of the torque converter at the time of shift change. As shown by the broken line in FIG. 4, since the rotation difference is small, there is a problem that a correction delay occurs and responsive control cannot be performed.

A rotation difference detection means 102 detects a rotation difference, and changes the control amount of the engine by a predetermined amount at the time of shift lever switching, and detects a rotation difference (actual rotation speed) between the engine rotation speed and the torque converter turbine rotation speed due to shift lever switching. The engine has a control amount correction means 103 that corrects the control amount of the engine (for example, intake air amount and ignition timing) according to the engine drive load (driving load).

As a result, the engine control amount is first corrected by a predetermined amount when the shift lever is switched, so there is no correction delay at the beginning of load application, and the engine control amount is adjusted according to the rotational difference between the engine and the torque converter turbine. Since the correction is performed, control accuracy also increases.
