JP2002002424A - Pedestrian danger sensing system for electric car - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent an accident of a pedestrian caused by reduction of traveling noise due to introduction of an electric car by an inexpensive device. SOLUTION: The accident is prevented by providing a laser beam sensing device (1), a radio wave sensing device (2) and a speaker (3) on the front part of the electric car and originating normally comfortable automobile traveling noise (simulated traveling noise) by a noise sensing device (4) controlled by a computer. In an emergency, the accident is avoided by sound by a transmission to a cellphone of the pedestrain. Electromagnetically traveling records are left in the noise sensing device/sound volume control device controlled by the computer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects an object (both using a laser beam and a radio wave) under computer control and constantly emits a variable volume simulated running sound from a speaker to prevent a traffic accident due to the introduction of an electric vehicle or the like. When an emergency accident is to be avoided, an emergency sound is emitted from the speaker and transmitted from the electric vehicle to the pedestrian's mobile phone, etc., and the accident is prevented by the automatic voice from the mobile phone. is there.

[0002]

2. Description of the Related Art Since electric vehicles and the like have not yet been introduced, there is no current state.

[0003]

In recent years, electric vehicles have been introduced to solve global environmental problems. In order to prevent traffic accidents expected after the introduction of electric vehicles, an inexpensive and concrete system will be introduced. It is assumed that.

[0004]

[Means for Solving the Problems] 1. Installation of a pedestrian danger detection system for an electric car or the like provided with the following a to f. 2. Installation of a pedestrian danger detection system for electric vehicles, etc. combining the following c) and d) (a) Installation of a computer-controlled external volume automatic measurement and detection device. (B) Automatically simulated running sound generated from the speaker according to the running environment. (C) In mountainous areas and places with low traffic, the object is detected by laser beams. (D) Automatic switching to the object detection device using radio waves in downtown areas and places with heavy traffic. (E) When an emergency accident is avoided, a speaker emits an emergency danger sound to pedestrians and the like. (F) When an emergency accident is to be avoided, the accident is prevented from being transmitted from the car to a mobile phone or the like and sound. The device is operated as described above.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS It is considered that when an electric vehicle is introduced, the noise of the instructor is dramatically reduced, while the number of car accidents increases rapidly without pedestrians or elderly people noticing the approach of the vehicle. For this reason, a computer-controlled automatic variable comfortable vehicle running sound (simulated running sound) within the regulations of the Noise Prevention Law is always generated from the speaker 3 to prevent a pedestrian from a traffic accident or the like. In a place with a small traffic volume, the noise detection device / volume control device 4 by the computer functions the laser beam object detection device 1 to generate a comfortable driving sound of the vehicle from the speaker 3 to prevent pedestrian danger, and in a place with a large traffic volume. The computer automatically activates the noise sensing device / volume control device 4 to activate the radio wave object sensing device 2 to generate an automatically variable comfortable running sound (simulated running sound) (sound from the sneaker 3) within regulations such as the Noise Prevention Law. Generated to help prevent pedestrian accidents. At the time of avoiding an emergency accident, an emergency danger sound is emitted from the vehicle-installed speaker 3 and further transmitted from the computer of the car to a pedestrian's mobile phone or the like, and the danger is notified to the pedestrian or the like by voice from the mobile phone.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A computer-controlled external volume automatic measurement and sensing device is provided, so that simulated running sounds within the regulations of the Noise Prevention Law appear as automatically variable sounds depending on the situation, and psychologically sense human emotions. A simulated running sound that does not harm can be made, so an environment-friendly device can be made. It has the advantage of being able to operate as a system quickly and inexpensively because it uses existing equipment such as speakers. In mountainous areas, it uses an object recognition device (considering the living environment) using a laser beam, In places where there is a lot of traffic, the system automatically switches to the object detection device using the existing radio wave, so that the safety is high. If one of the devices breaks down, only one device can urgently cope with it and the safety is high. When an emergency accident is avoided, it is very effective because a dangerous call is made from a car to a mobile phone or the like and a voice is transmitted from the mobile phone which seems to give the highest impression to the human mind.

[0007]

According to the present invention, a system for contributing to the prevention of a new type of traffic accident by the introduction of an electric vehicle is a system that can be built immediately with existing devices, and even if a car navigation system or a new technology is introduced, the system itself. Has the advantage that new technologies are readily available.
