[0001]

BACKGROUND OF THE INVENTION The present invention is directed to the fact that a passenger is in the process of getting off or just before getting off, and that the taxi is in a temporary stop state in which the brake pedal is continuously depressed, and the taxi is being decelerated. For example, the present invention relates to an accident prevention device for a taxi that can reliably notify the following vehicle that the taxi is in a state requiring attention to the following vehicle.

2. Description of the Related Art Conventionally, as a rear lamp in an automobile,
It is equipped with parking lights and brake lights. Parking lamp is ON-O by manual operation
This is for FF, and is for indicating that the vehicle is parked. The brake lamp is for notifying the following vehicle that the brake pedal has been stepped on, such as a deceleration state during traveling or a temporary stop state at a signal or the like.
Brake lights are extremely important to prevent rear-end collisions, but conventional brake lights are relatively low near the bumper, so it is somewhat difficult to confirm from the following vehicles, especially the following vehicles. When the vehicle is a large vehicle such as a truck, it is more difficult to check the brake lamp because the cab is expensive. For this reason, in recent years, for example, a third lamp for warning, which interlocks with a brake lamp, has been provided at a position where it is easy to check from a following vehicle, such as a shelf of a rear seat.

[0003]

However, although such a third lamp is mounted at a position where it can be easily seen from the following vehicle, like the brake lamp, it is simply lit while the brake pedal is being depressed. Since it is only to continue to do, there is no change and there is little stimulation, it is not possible to continue the attention of the driver of the following vehicle, especially when the brake pedal is depressed frequently or the brake pedal is continuously depressed. As a result, the effect of alerting is almost lost as a result of the eye getting used to the lighting state of the brake lamp, and the effect of preventing accidents cannot be expected so much. Further, taxis have more important problems from the viewpoint of accident prevention. That is, although taxis frequently get on and off passengers, there is conventionally no means for giving a notice to a succeeding vehicle that the passenger is getting off. If the taxi is stopping forward, there is no way to tell the following car whether the stop is just waiting due to passengers or rest, or to stop passengers. The current situation is that there are many accidents in which a succeeding vehicle that tries to pass a side part collides with another vehicle. The present invention has been made in view of the current situation, and that passengers are in the process of getting off or just before getting off, and that the taxi is in a temporary stop state where the brake pedal is continuously depressed, and further during deceleration. It is intended to provide means for notifying the following vehicle that the taxi is in a state requiring attention for the following vehicle.

[0004]

The gist of the first invention for solving the above problems is to provide a warning lamp that blinks at a position where it can be easily identified from a following vehicle separately from a stop lamp and a parking lamp. Is a condition that no new distance pulse is generated within a certain period of time until the payment button is pressed and a new distance pulse is input thereafter, or no new distance pulse is generated within a certain period of time. The feature is that the blinking operation is maintained while the brake pedal is depressed.

Further, the second invention is characterized in that when the brake pedal is depressed, the warning lamp is made to blink regardless of the presence or absence of the distance pulse, and the following vehicle is also notified of the deceleration operation during traveling. .

[0006]

The function of the accident prevention device in the taxi of the first invention is
By monitoring the occurrence status of the distance pulse, it is determined whether the taxi is completely stopped or substantially stopped.If the taxi is completely stopped or substantially stopped, the payment button is Detects whether it is pressed or the brake pedal is depressed. When the pay button is pressed under the above condition, it is determined that the passenger is about to get off the vehicle, and the blinking of the warning lamp is started, and the blinking state is maintained until the vehicle starts moving and a new distance pulse is generated. When the brake pedal is depressed while the vehicle is completely stopped or substantially stopped, it is determined that the vehicle is temporarily stopped due to reasons such as waiting for a traffic signal, and the warning lamp starts blinking to brake. It keeps blinking while the pedal is held down. The monitoring of whether or not the pay button or the brake pedal is pressed and the monitoring of the presence or absence of the distance pulse are performed at the same time, but either one may be performed first. In the technique described in the second invention, the warning lamp starts blinking when the brake pedal is depressed regardless of the presence or absence of the distance pulse, and the blinking state is maintained while the brake pedal is continuously depressed. Therefore, the following vehicle can be made aware of not only the temporary stop state due to the reason such as waiting for a traffic signal but also the deceleration state during traveling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, details of the present invention will be described based on illustrated embodiments. FIG. 1 is an explanatory diagram showing an outline of a taximeter and a mechanism for calculating a charge in the taximeter. The taximeter 1 has a charge display section 2 in the center of the front panel,
Tariff operation buttons 3 and payment buttons 4 for instructing a mode at the time of traveling are arranged in a row in the lower part thereof, while a tariff display portion 5 for displaying the current mode is provided above the charge display portion 2.
It is a configuration in which is arranged. The charge display section 2, the tariff operation button 3, the payment button 4, and the tariff display section 5 may be arranged in other relationships. The calculation of the mileage in the taximeter 1 is performed by transmitting the rotation of the transmission gear 6 to the reduction gear box 8 via the flexible cable 7 to reduce the rotation speed and sending the reduced rotation to the pulse generator 9 to perform the rotation. The number of distance pulses corresponding to the number is given to the taximeter 1, and the taximeter 1 calculates the traveling distance by counting the number of the distance pulses. Also, although not shown, depending on the type of taximeter, there is a type in which the reduction gear box 8 is not provided and the rotation of the transmission gear 6 is directly sent to the pulse generator 9. According to the present invention, a warning lamp is provided at a position where it can be easily recognized by a following vehicle, and the warning lamp flashes under a specific condition to alert the driver of the following vehicle. The warning lamp is arranged at a conspicuous position from the following vehicle. For example, it is preferable to provide the warning lamp 10 at a position visible through the rear window 11 behind the rear seat as shown in FIG. Warning light 10
The shape and the number of the warning lamps 10 are arbitrary, and for example, one horizontally long warning lamp 10 can be provided at the center of the rear window 11, or one small warning lamp 10 can be provided on each side of the rear window 11.

The first invention adopts the following condition as a condition for blinking such a warning lamp 10. That is, it is determined whether or not the taxi is stopped when the payment button 4 is pressed or the brake pedal is depressed, and if the taxi is stopped, the warning lamp is made to blink. This is shown in FIG.

When the taxi is traveling, distance pulses are generated at short time intervals according to the number of distances traveled, but as the taxi decelerates, the distance pulses become longer,
When completely stopped, no new distance pulse is generated. In the present invention, time measurement is started from the time when a pulse is generated, and it is considered that the taxi is stopped when a new distance pulse is not detected even after a certain time a has passed (t> a). There is. The state in which a new distance pulse is not generated even after the lapse of a certain period of time includes not only a complete stop state but also a very low speed running just before the stop, which can be said to be a substantial stop state. In the first embodiment, as shown in FIG.
No new range pulse is generated within a certain time a (t>
a) When the pay button 4 is pressed, or when a new distance pulse is not generated within a certain time a (t> a) and the brake pedal 12 is depressed, the warning lamp 10 is made to blink. is there. If no new distance pulse is generated within a certain time period (t> a) and the payment button 4 is pressed, the warning lamp 10 starts blinking when the payment button 4 is pressed, and the next new distance is reached. The blinking state is maintained until a pulse is generated. If no new distance pulse is generated within a certain time period (t> a) and the brake pedal 12 is depressed, the warning lamp 10 blinks while the brake pedal 12 is continuously depressed. It is something that lasts. In the accident prevention device of the first invention, the warning lamp 10 automatically starts blinking immediately before the passenger gets off, and the warning lamp 10 starts until the passenger gets off and the taxi starts.
The blinking state of will be maintained, and the blinking state will be automatically canceled when the taxi starts. Therefore, it is possible to inform the following vehicle whether the taxi is simply stopped for the purpose of waiting for passengers or resting, or for stopping passengers, and it is possible to notify the opening of the door and the passenger's exit in advance. It can contribute to the prevention of rear-end collisions. Also, when the taxi is temporarily stopped due to a signal waiting or the like, the warning lamp 10 blinks to notify the following vehicle, so that the driver of the following vehicle can be alerted.

In the first invention, when the brake pedal 12 is stepped on, the state of generation of the distance pulse is monitored, and the warning lamp 10 is made to blink only when a new distance pulse is not generated even after the lapse of a certain time a. However, in the second invention, when the brake pedal is depressed, the warning lamp 10 is made to blink regardless of the presence or absence of the distance pulse. That is, in the second device, similarly to the first device, in addition to the basic recognition that the temporary stop state is a caution state due to reasons such as passengers getting off the vehicle and waiting for a signal, the deceleration state during traveling also requires caution. Is in a state
This was done based on the recognition that it is necessary to inform the following vehicle of the condition.

The second invention is a warning lamp 10 as shown in FIG.
The following conditions are adopted as the blinking conditions of. That is, when a new distance pulse is not generated within a certain time a (t> a) and the pay button 4 is pressed, or while the brake pedal 12 is depressed, a warning lamp is irrelevant regardless of the presence or absence of the distance pulse. It makes 10 blink. In the second invention, the following lamp can be notified by blinking the warning lamp 10 not only when the passenger gets off the vehicle and when the vehicle is waiting for a signal, but also when the vehicle is decelerating.

[0012]

According to the first aspect of the present invention, a warning lamp that blinks at a position where it can be easily identified from a following vehicle is provided separately from the brake lamp and the parking lamp, and the warning lamp does not generate a new distance pulse within a certain time. Blinks until the payment button is pressed under a state and a new distance pulse is input after that, or when the brake pedal is depressed while no new distance pulse is generated within a certain period of time. Since it is configured to continue, it is possible to notify the following vehicle in advance of the passenger's disembarking, it is possible to inform the succeeding vehicle that the passenger is getting off, and even if it is temporarily stopped due to a signal waiting etc. You can inform the following cars.
And since the warning lamp is installed in a prominent position from the following vehicle and blinks, the following vehicle does not overlook the warning signal emitted by the taxi, and for example, the warning signal can be reliably transmitted even during heavy fog or rain. Can be recognized,
It can contribute to the prevention of rear-end collisions.

Further, the accident prevention device of the second invention starts blinking when the pay button is pressed under the condition that a new distance pulse is not generated within a certain time, and the blinking state is changed to a new distance pulse. It is the same as in the first aspect of the invention until the input is input, but the blinking operation is continued while the brake pedal is depressed regardless of the presence or absence of the distance pulse. Therefore, the warning lamp can be made to blink even when the vehicle is in a deceleration state during traveling, which can also contribute to the prevention of a rear-end collision accident during traveling.
