ためにこの自動シフトアンプ直後に変速操作をしなけれ
ばならない煩わしさがあった。However, conventional automatic transmissions do not notify the driver of the shift point in advance, so when the engine speed increases and the shift point is reached, the road ahead may be a slope, an intersection with a stop light, or a traffic jam. Even if the vehicle is on a road, etc., it will automatically shift amplifier. Therefore, the driver has to perform a gear change operation immediately after the automatic shift amplifier in order to smoothly drive the vehicle thereafter, which is a hassle.

機を提供することを目的とする。The present invention improves this point by giving advance notice to the driver of the shift change before reaching the shift point, and allowing the driver to prohibit unnecessary shift changes depending on road traffic conditions.
It is an object of the present invention to provide an automatic transmission that allows the automobile to run smoothly thereafter.

These sensors 1
The outputs of .about.3 are connected to the input of the CPU 7 via the input interface 6 of the microcomputer 5 mounted on the vehicle.

As shown in FIG. 2, the storage device 8 stores a transmission shift curve in functional form, which is represented by a solid line with the rotational speed of the transmission output shaft on the horizontal axis and the engine load on the vertical axis. There is. Also C
A shift actuator 10 that changes the transmission gear position is connected to the PU 7 via an output interface 9.

小さくして得たものである。A characteristic configuration of the present invention is that an alarm chime II provided at the driver's seat is connected to the C'PU 7 via an output interface 9, and an alarm curve represented by a broken line in FIG. 2 is stored in the storage device 8. It's somewhere. This warning curve is obtained by shifting the speed change curve in the horizontal axis direction and reducing the rotational speed by a certain value.

２速から第３速にシフトアップする。With this configuration, as shown in Fig. 2, the transmission gear position is 2nd speed, the load is p, and the rotation speed is from point A with p and rotation speed q1 to point B on the alarm curve where the rotation speed has increased to 92. When the time limit is reached, the CPU 7 sends an alarm activation signal to the alarm chime 11, and causes the alarm chime II to emit an electronic sound. Furthermore, when the rotational speed is increased from 92 to 93 and reaches point 0 on the shift curve from point B, the CPU sends a shift up signal to the shift actuator 10 to change the shift gear position from 2nd gear to 3rd gear. Shift up.

行を円滑に行うことができる。Here, when the warning chime 11 emits a sound, the driver determines whether it is necessary to change the shift of the automatic transmission based on the road traffic situation at hand, and if the driver is approaching a slope or an intersection with a stop signal, etc. , change the gear position to 2nd by manual operation.
This eliminates unnecessary shift door knobs and allows for smoother driving.

エンジンの回転速度を検出するセンサでもよい。In the above example, the rotation sensor is a sensor that detects the rotation speed of the output shaft of the transmission, but it may also be a sensor that detects the rotation speed of the input shaft of the transmission, that is, the engine.
また警報曲線を変速曲線の横軸方向にずらして得る例を
示したが、変速点に達する一定時間前に警報チャイムが
鳴音するように構成することもできる。Further, although an example has been shown in which the alarm curve is obtained by shifting the shift curve in the horizontal axis direction, it is also possible to configure the alarm chime to sound a certain period of time before the shift point is reached.

By configuring it to operate,
If the driver can know the shift point in advance and it is determined that the current road traffic situation does not require an automatic shift change, automatic shift changes by the driver's manual operation are prohibited. This has an excellent effect of making it possible for the car to run smoothly thereafter.
