In addition, 42a, 42b, and 42c are load display light emitting diodes which visually display a control output from the display control unit A4 using a display light emitting diode (LED),

30 indicates that the rotation of the rotating machine guide 41 or the load indicating light emitting diodes 42a, 42b, and 42c are continuously turned on to visually check the engine speed in the instrument panel according to the signal of the controller. It is a driving unit.

Here, the load display light emitting diodes 42a, 42b, and 42c are provided as a plurality of display light emitting diodes (LEDs), which are added to the engine speed counter 40 and sequentially lighted by an output signal of the display control unit A4. It is a display that the driver visually checks the rapid start and acceleration according to the operation and is displayed in green, yellow, and red according to the load.

On the other hand, it is also preferable that the toggle switch 20 is provided at the front end of the driving unit so that the engine rotation counter or the load display light emitting diode can be selectively used according to the user's selection.

It can be used in various forms using this, firstly, as shown in Figure 2a according to the user's choice, the rotary guide 41 is to be used alone for the engine speed measurement, and

Secondly, as shown in FIG. 2B, the rotary machine guide 41 is used for measuring the engine speed, and the load indicator light emitting diodes 42a, 42b, and 42c have fuel cutoff (between 0-1) and acceleration highest efficiency.

A control sequence for displaying the load display LED is as follows based on FIG. 3.

First, the reference value is set. Here, the reference value is set by presetting the overload condition generated during rapid acceleration and sudden departure according to the vehicle type to a certain numerical value. It is preferable to be shipped as.

After the car is started, it is first determined whether the engine is stable for a certain time (engine stability test) (S1).

If it is determined that the starting stability is made in step S2, the engine speed counter 40 of the instrument panel can be used in various ways using the toggle switch 40 (S3), the engine speed measurement alone (S4), and the load display alone ( S6) It is natural to use them as a mixing type S5 (the rotating instructions are used for measuring the engine speed and the load display light emitting diodes are load displays).
