Abstract

PROBLEM TO BE SOLVED: To eliminate the no-sound state at motor driving and to improve safety by generating a sound that differs from a horn on motor driving. SOLUTION: A hybrid automobile 1 with a motor 2 and an engine 3 that are driven by a battery 10 is constituted so that it drives only with the motor 2 or with the motor 2 and the engine 3 combined, and drives only with the motor 2 at low-speed driving with less load. Then, the hybrid automobile 1 has a sound generating part 4, and a sound signal 4a from it is connected a sound source 6 via a switch 5. Then, when the hybrid automobile 1 is driven only by the motor 2 on actual driving, the switch 5 is operated manually, thus generating an imitated engine sound or the like that is similar to an engine sound from the sound source 6 and hardly turns into a noise similar to a horn sound, hence appealing the presence of the automobile to persons around the automobile, and improving the safety in an electric vehicle and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor-driven motor vehicle, and more particularly to a motor-driven motor vehicle or a hybrid vehicle using a motor and an engine, which generates noise different from horn when the motor is running, thereby reducing noise during motor running. The present invention relates to a new improvement for eliminating a condition and improving safety.

[0002]

2. Description of the Related Art Conventionally, as a motor-driven vehicle of this type, that is, a hybrid vehicle using only a motor or a motor and an engine, the engine is stopped when the motor is running or the motor and the engine are used together. I was running.

[0003]

Since the conventional motor-driven automobile is configured as described above, there are the following problems. In other words, when traveling by motor alone, almost no sound is emitted outside and the sound is almost silent, so when traveling at low speed on a street with crowds, people do not notice the car and it is dangerous. Sometimes it was. Also, when the horn sounded frequently, it was noisy.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in particular, generates a sound different from horn during motor running, thereby eliminating a silent state during motor running and improving safety. It is an object of the present invention to provide a motor-driven vehicle that is improved.

[0005]

SUMMARY OF THE INVENTION A motor-driven vehicle according to the present invention is a battery-driven vehicle that runs using only a motor or a motor and an engine. It is a configuration for running. Further, the sound is a continuous sound or an intermittent sound, and the generation of the sound can be stopped by a switch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a motor-driven automobile according to the present invention will be described below with reference to the drawings. 1 is a hybrid vehicle having a motor 2 and an engine 3 driven by a battery 10. The hybrid vehicle 1 includes only a motor 2,
Alternatively, the vehicle is configured to travel in a state in which the motor 2 and the engine 3 are combined, and is configured to travel only by the motor 2 during low-speed traveling with a small load.

[0007] The hybrid vehicle 1 is provided with a sound generator 4 comprising an amplifier and the like shown in FIG.
Is connected to a sound source 6 such as a speaker via a switch 5. The switch 5 is provided on a dashboard (not shown) or a handle (not shown) of the hybrid vehicle 1. In addition, the present invention is not limited to the hybrid vehicle 1, and can be applied to a battery vehicle that runs only by the motor 2 using the battery 10 or a hydrogen fuel cell vehicle that uses only the motor 2 using a hydrogen fuel cell (not shown).

Next, when the vehicle is running only by the motor during the actual running, the switch 5 is operated by hand, so that the sound source 6 generates a sound other than a horn, such as a peep, beep, or a pseudo engine sound similar to the sound of an engine. Sounds that are less likely to be noise can be produced. Further, without using the switch 5, for example, the sound can be automatically generated in conjunction with the driving of the motor.

[0009]

The motor-driven vehicle according to the present invention is configured as described above, so that the following effects can be obtained. That is, since sound can be generated during motor running, the presence of the vehicle can be appealed to people around the vehicle, and safety such as electric automatic operation can be improved.
