Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to an engine condition sensing device that continuously outputs a vibration signal according to an engine condition.

(Problems to be Solved by Conventional Techniques and Inventions) When driving an automobile, a driver usually drives while visually checking the traveling speed with a speedometer and the engine speed with a tachometer. is there. Further, the traveling speed and the condition of the engine can be sensibly sensed by the sound and vibration of the engine, the change of the scene outside the vehicle, the wind pressure and the like.

In this way, the driver tries to drive safely or not to impair the condition of the car based on the instruments and the information obtained intuitively. Accidents due to troubles are increasing year by year.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an engine condition sensing device that enables a driver to always drive while feeling the condition of the engine as a vibration signal with the body and contribute to safe driving. Is to do.

(Means for Solving the Problems) In the first invention, an input section for continuously detecting the vibration of an engine mounted on an automobile and converting a detection signal into an electric signal, and an output section output by the input section. It comprises an amplifying section for amplifying an electric signal, and an output section for receiving the amplified signal output from the amplifying section and vibrating the vibrating body.

According to a second aspect of the present invention, instead of the input section of the first aspect, an input section for continuously inputting an engine ignition signal from an ignition circuit is provided.

According to a third aspect of the present invention, instead of the input unit of the first aspect, an input unit for continuously detecting intake or exhaust of an engine and converting a detection signal into an electric signal is provided.

(Operation) In the first invention, the input section is directly attached to the engine body, for example, and the output section is embedded in the driver's seat, for example, or attached to the seat from the outside. If it is transmitted, the driver can always sense the condition of the engine as a vibration signal with the body.

In the second invention, the input section is connected to the ignition circuit of the engine to continuously input the ignition signal, but the output section is embedded in the driver's seat as in the first invention, or is attached to the outside of the seat. To use.

In the third invention, the intake or exhaust pressure of the engine is continuously input at the input section through, for example, a pressure-sensitive element. However, the output section is also embedded in the driver's seat or externally, similarly to the first invention. Used by attaching to

(Embodiment) FIGS. 1 and 2 show an embodiment of the first invention. As shown in FIG. 1, an input unit 3 is directly attached to an appropriate portion of an engine 2 mounted on an automobile 1 to operate the vehicle. In the seat 4 of the seat, the output unit 6 is embedded in a portion where the back of the driver 5 contacts.

The input unit 3 continuously detects the vibration of the engine 2 and converts the detection signal into an electric signal A.
As shown in the figure, the engine condition sensing device 7
Comprises an input section 3, an amplifier 8 for amplifying the electric signal A output from the input section 3, and the output section 6 for receiving an amplified signal B output from the amplifier 8.
Has a vibrating body 9 that vibrates according to the amplified signal B.

In the above configuration, when the intensity and the amplitude of the vibration of the engine 2 change during the operation of the automobile 1, the output unit 6 responds accordingly.
It is possible to drive while feeling the vibration of the vibrating body 9 on the back. For example, when a strong vibration is felt, the rotation speed of the engine 2 is high, and therefore the running speed is high, and the user can feel that the running speed is high, and the processing of reducing the depression amount of the accelerator pedal 10 can be performed quickly. Therefore, it is possible to prevent excessive speed and engine trouble from occurring.

Further, as a secondary effect, the driver 5 can enjoy driving while feeling a sense of unity with the engine 2.

Although the output unit 6 has been described as being embedded in the seat 4 in the above embodiment, the present invention is not limited to this, and the point is that the output unit 6 is used so that the vibration of the output unit 6 is transmitted to the body of the driver 5. If possible. For example, the output unit 6 may be attached (attached) to the outside of the seat 4, may be attached to an appropriate portion of a safety belt, or may be attached to the body of the driver 5 by a belt or the like. .

3 and 4 show an example in which the output unit 6 is attached to the outside of the seat 4. The output unit 6 includes, for example, a vibration plate (vibration body) 9 opposed to the magnet yoke 11 and a spring. The yoke 11
The diaphragm 9 is intermittently attracted to the yoke 11 by applying the electric signal output from the amplifying unit 8 to the coil 12 wound around the coil 12, and the strength and amplitude of the diaphragm 9 are changed according to the supplied current. Shall change.

FIG. 5 shows an embodiment of the second invention, in which an ignition signal input unit 13 is connected to an ignition circuit of an engine, and the ignition signal (electric signal) is transmitted through an amplification unit 8 as in FIG. And outputs it to the output unit 6.

FIG. 6 shows an embodiment of the third invention. In the intake / exhaust signal input section 14, the intake or exhaust pressure of the engine is continuously input through, for example, a pressure-sensitive element and converted into an electric signal.

Then, similarly to FIG. 2, this is output to the output unit 6 via the amplifying unit 8.

(Effects of the Invention) As described above, according to the present invention, the vibration of the engine is detected at the input unit and converted into an electric signal, or the ignition signal of the engine is input by the ignition circuit, and the engine is further sucked.・ Continuously input the exhaust signal and convert it to an electric signal.
This is amplified by the amplifying unit to vibrate the vibrating body of the output unit, so that the driver can sense the vibration of the vibrating body with his body and drive while always intuitively grasping the condition of the engine. It is effective in preventing accidents caused by excessive speed and engine trouble. Further, there is an effect that the driver can enjoy driving while feeling a sense of unity with the engine.
