Abstract

PROBLEM TO BE SOLVED: To decrease the amount of exhaust gas by stopping the engine and provide an optimum mode in each system related especially to ITS(Intelligent Transportation System). SOLUTION: This automatic stop unit comprises an engine automatic stop unit 3 which stops the engine subject to inclusion of the vehicle running at or lower than the set vehicle speed, and an ETC unit 2 which receives a compulsive stop signal transmitted from the ETC(Electric Toll Collection system) gate and forces the engine automatic stop unit to stop the engine even though the conditions are not met. The ETC unit makes the engine stop signal to a High level when the vehicle receives the compulsive stop signal while it is running on the ETC lane, and makes the engine stop signal to a Low level when it becomes impossible to receive the compulsive stop signal. The engine automatic stop unit outputs a stop signal to stop the engine from an output processing part when the effective signal and the engine stop signal are in the High level and outputs re-start signal to stop the engine when they are in a High level.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic engine stop device for a vehicle that receives a signal from outside the vehicle and stops the engine.

[0002]

2. Description of the Related Art Conventionally, as an automatic engine stop device for a vehicle of this type, a signal waiting during driving of an automobile,
There is a known one that stops an engine during a stop due to traffic congestion (for example, see Japanese Patent Application Laid-Open No. 9-42005).
In this vehicle, the engine is automatically stopped on condition that the vehicle speed is zero and the vehicle is in a set traveling state including a state where the transmission is in a neutral position. It is designed to

[0003]

As means for solving current traffic problems such as deterioration of the global environment due to an increase in exhaust gas due to traffic congestion, ITS (Intelligent Transpor
t Systems: Intelligent Transportation Systems).
One of the ITS technology menus is ETC (Elec
tronic Tool Collection (automatic toll collection system) is known, and this ETC is configured to collect tolls by radio signals at gates of toll roads. It is possible to omit payment of a fee or the like and restarting the vehicle. For this reason, alleviation of traffic congestion and reduction of exhaust gas have been achieved.

[0004] As one of the ITS pedestrian support menus, a visually impaired person guidance system has been put to practical use. In the visually impaired person guidance system, the visually impaired person is guided by a voice from a road (infrastructure) side to guide the visually impaired person.

Further, a special vehicle management system for managing special vehicles has been considered as one of the ITS road management optimization menus. In this case, provision of construction information and the like, and traffic signal control for regulating traffic to general vehicles, etc., have been considered.

[0006] Even when such an ITS system is provided, it is desirable to reduce the exhaust gas by stopping the engine.

The present invention has been made in view of such circumstances, and an object of the present invention is to reduce the amount of exhaust gas by stopping the engine. It is to provide an optimal mode in the system.

[0008]

In order to achieve the above-mentioned object, the present inventor forcibly stops the engine by a signal from outside the vehicle in a necessary and safe state using each system of the ITS. The present invention has been completed by focusing on the points.

Specifically, the present invention provides an automatic engine stop means for stopping an engine on condition that the vehicle is in a set traveling state including a state in which the vehicle is at or below a set vehicle speed, and a forced stop signal transmitted from outside the vehicle. And a forcible stop means for stopping the engine regardless of whether the vehicle is in the set traveling state when the signal receiving means receives a forcible stop signal. Matters. In this case, the engine is stopped irrespective of the running state of the vehicle in response to the forced stop signal from the outside of the vehicle, thereby further reducing exhaust gas and the like.

On the other hand, by means of an automatic engine stop means for stopping the engine on condition that the vehicle is in a set traveling state, the engine is automatically stopped, for example, when a traffic signal is waiting or when the vehicle is stopped due to traffic congestion, thereby reducing exhaust gas. Is achieved.

The engine may be stopped by the forced stop means so that the forced stop means outputs a signal directly to the engine, or a signal is output to the engine automatic stop means. The automatic engine stop means may output a signal to the engine.

The engine may be stopped by, for example, stopping the supply of fuel, stopping the ignition of the engine, or stopping the supply of air. From the viewpoint of reducing the exhaust gas, the supply of the fuel is stopped. It is preferable to stop the engine by stopping the engine.

[0013] In a case where such a system that stops the engine in response to a signal from outside the vehicle is applied to, for example, an automatic toll collection system, the following may be performed.

That is, a signal output means for transmitting a forced stop signal to the traveling vehicle detects that the vehicle is traveling on an automatic toll collection lane of an automatic toll collection system provided near the gate. Detecting means, the forced stop means, detecting that the traveling lane detecting means is traveling in the automatic toll collection lane, and,
When the signal receiving means receives the forcible stop signal, the engine automatic stop means causes the engine to stop, and after the engine is stopped by the engine automatic stop means, the signal receiving means The engine may be restarted when the stop signal is no longer received.

In this case, by receiving the forced stop signal near the gate of the automatic toll collection lane, the engine of the vehicle is forcibly stopped, and the vehicle passes through the gate by inertia. Then, the toll is collected.

As described above, by forcibly stopping the engine when passing through the gate, the amount of exhaust gas is reduced, and the vehicle is constantly moved by inertia. The purpose of mitigation is achieved.

When the vehicle passes through the gate and moves to an area where the forced stop signal is not received, the stopped engine is restarted by the forced stop means to return to normal running. Become.

The traveling lane detecting means for detecting a vehicle traveling on the automatic toll collection lane allows the vehicle traveling on a lane other than the automatic toll collection lane, for example, a lane not compatible with the automatic toll collection system, to perform the above compulsory operation. Even if the stop signal is received, the engine will not be stopped. For this reason, the engine is stopped only for the vehicle for which the fee is to be paid by the automatic fee collection system,
Confusion around the gate is prevented.

In such an automatic toll collection system, for example, there is a possibility that there is a problem how to control offending vehicles such as unpaid vehicles that cannot be paid due to insufficient balance in a bank account. Therefore, the forced stop means
If the automatic toll collection system does not collect the toll, the engine may not be restarted.

Further, the signal output means is configured to transmit a restart prohibition signal to the vehicle when the toll is not collected by the automatic toll collection system. The engine may not be restarted when the restart prohibition signal is received.

In this case, even if the vehicle for which the fee has not been paid passes through the gate and no longer receives the forced stop signal, the engine remains stopped by receiving the restart prohibition signal. Therefore, the vehicle is prevented from continuing to run, and it becomes possible to crack down on the vehicle for which the fee has not been paid.

Further, a driving lane detection for detecting that the own vehicle is running on an automatic toll collection lane of an automatic toll collection system provided near the gate with signal output means for transmitting a forced stop signal to the running vehicle. Means, a signal output means, when the toll is not received by the automatic toll collection system, configured to transmit a restart prohibition signal to the vehicle, the forced stop means,
The driving lane detecting means detects that the vehicle is traveling in the automatic toll collection lane, and when the signal receiving means receives the forced stop signal, the engine automatic stopping means stops the engine, After the engine was stopped by the engine automatic stop means, the engine was restarted when the signal receiving means became unable to receive the forced stop signal, while the engine was stopped by the engine automatic stop means. Later, when the vehicle passes through the gate and the signal receiving means receives the restart prohibition signal, the engine may not be restarted. In this case, the vehicle running on the automatic toll collection lane receives the forced stop signal, the engine of the vehicle is forcibly stopped, and the vehicle passes the gate by inertia to collect the toll. And
When the vehicle moves and passes through the gate to be in a state where the forced stop signal cannot be received, the stopped engine is restarted by the forced stop means to return to normal running. On the other hand, a vehicle for which payment has not been paid is prohibited from restarting the engine only when the vehicle has definitely passed the gate. Therefore, the vehicle is prevented from stopping in the middle of the gate, and an accident such as a rear-end collision or a traffic jam due to a following vehicle being unable to pass through the gate is avoided.

Each of the above-described structures is applied to an automatic toll collection system. As a system for stopping the engine by such a forced signal from outside the vehicle, for example,
The present invention may be applied to a system in which an engine of a vehicle is forcibly stopped in an emergency state to prevent the vehicle from continuing to run. Specifically, as described in claim 6,
Forced stop means, when traveling on a road with signal output means for outputting a forced stop signal when an emergency state to stop the traveling vehicle traveling on the travel path occurs,
The engine may be stopped when the signal receiving unit receives the forced stop signal. here,
"Emergency condition" means, for example, a traffic obstruction ahead of the roadway,
For example, traffic impassability due to traffic accidents, impassability due to road damage has occurred, or abnormal weather in front of the travel path,
For example, a state such as a typhoon, a tornado, a heavy rain, an earthquake, or the like, or a state where an emergency vehicle such as an ambulance, a fire engine, or a patrol car approaches.

In this case, by forcibly stopping the running of the vehicle in the emergency state as described above, for example, even if an emergency state in which the driver does not notice occurs, an accident or the like can be avoided. , It is possible to ensure safety.

Further, in a route guidance system for a disabled person, which guides a disabled person such as a visually impaired person by voice, a system for stopping an engine in response to a signal from outside the vehicle may be applied. Specifically, as set forth in claim 10, there is provided a route guidance system for a disabled person that guides the route to a disabled person by voice, and the route guidance system for a disabled person is provided to a nearby vehicle during voice guidance. A signal output unit that outputs a forced stop signal may be provided, and the forced stop unit may be configured to stop the engine when the forced stop signal is received. In this case, when performing the voice guidance, the voice guidance is prevented from being disturbed by the engine noise of the nearby vehicle, and it is possible to safely guide the disabled person. In addition, it is possible to reduce exhaust gas caused by stopping the engine.

[0026]

As described above, according to the apparatus for automatically stopping an engine of a vehicle according to the present invention, the engine is stopped irrespective of the running state of the vehicle in response to a forcible stop signal from outside the vehicle. It is possible to further reduce exhaust gas in a safe case.

, A restart signal is output.

Next, the operation and effect of the first embodiment will be described.

First, when the vehicle 9a corresponding to the ETC runs on the ETC lane 11a on the entrance side, a signal is transmitted from the entrance side antenna transmitter 13, and ID information is transmitted between the ETC gate 1 and the ETC unit 2. And so on. Thus, it is determined that the vehicle is traveling on the ETC lane 11a (see steps S11 to S13 in FIG. 3).

Then, a forced stop signal is transmitted from the antenna transmitter 13 on the entrance side of the ETC gate 1.
By receiving this forced stop signal, both the engine stop signal and the valid signal from the ETC unit 2 are Hi.
gh level (see the bold line in the upper part of FIG. 1). As a result, an engine stop signal is output from the output processing unit 34 of the automatic engine stop unit 3 (step S18 in FIG. 3 and step S24 in FIG. 5). reference). As a result, the engine is forcibly stopped, and the vehicle passes through the ETC gate 1 due to inertia (see the rightward white arrow in the figure).

When the forced stop signal cannot be received due to the movement of the vehicle, the engine stop signal is set to the low level from the ETC unit 2 (the thick line at the top of FIG. , The engine is restarted (see step S111 in FIG. 3 and step S23 in FIG. 5). The reason why the forced stop signal cannot be received is that the forced stop signal is transmitted to a vehicle entering from the entrance direction of the ETC gate 1, and therefore, it is difficult for radio waves to reach the opposite side. For this reason, if the vehicle moves and passes through the ETC gate 1 as described above, the forced stop signal cannot be received.

When the engine is restarted, the vehicle returns to normal running.

As described above, by forcibly stopping the engine when passing through the ETC gate 1, the exhaust gas can be reduced, and the vehicle always moves by inertia. One of the objectives is to alleviate congestion.

On the other hand, in the case of the exit side, similarly to the entrance side, the vehicle 9b corresponding to the ETC runs on the exit side ETC lane 12a, thereby forcing the vehicle 9b from the exit side antenna transmitter 14 of the ETC gate 1. A stop signal is transmitted. By receiving this forced stop signal, both the engine stop signal and the valid signal from the ETC unit 2 are set to the high level (see the thick line at the bottom in FIG. 1). As a result, the output processing unit 34 of the automatic engine stop unit 3 is set. (See step S118 in FIG. 4 and step S24 in FIG. 5). As a result, the engine is forcibly stopped, and the vehicle passes through the ETC gate 1 by inertia (see the white arrow pointing to the left in the figure).

When the vehicle moves, the forced stop signal cannot be received, and when the payment of the fee is completed, the engine stop signal is set to the Low level from the ETC unit 2 (FIG. 9). , The engine is restarted (see step S124 in FIG. 4 and step S23 in FIG. 5). On the other hand, even if the forced stop signal cannot be received, if the payment of the fee is not completed, the engine stop signal from the ETC unit 2 becomes H
Since the level is set to the high level, the stop signal is output from the automatic engine stop unit 3 and the engine remains stopped (see step S122 in FIG. 4 and step S23 in FIG. 5). For this reason, it becomes impossible for the above-mentioned vehicle to continue running, and it has to stop at, for example, a road shoulder. With such a configuration, it becomes possible to control vehicles for which payment has not been made.

[0074] The case where the fee is not paid as described above includes, for example, a case where the fee cannot be paid due to insufficient balance of the bank account.

Unlike the first embodiment, the ETC gate 1 transmits a restart prohibition signal to a vehicle for which a fee has not been paid to stop the vehicle. 2 ".

(Part 1) FIG. 6 shows an ETC according to “Part 1”.
4 shows a flowchart of a process in a gate 1, in which the ETC gate 1 determines whether or not a vehicle has passed through the ETC gate, and prohibits the restart of the engine when the vehicle has passed through the ETC gate. It is configured to transmit a restart prohibition signal.

The other components of the ETC gate 1, the ETC unit 2, and the automatic engine stop unit 3 are the same as those of the first embodiment, and the same members are denoted by the same reference numerals. The description is omitted.

Next, the processing in the ETC gate 1 will be described with reference to the flowchart shown in FIG.

First, in step S31, the ETC information is transmitted to the traveling vehicle from the antenna transmitters 13 and 14 provided in the ETC gate 1.

Next, in step S32, it is determined whether or not a response (ID information) to the information transmitted in step S31 has been received from the traveling vehicle. If the response has been received, step S32 is executed.
On the other hand, if the reception has not been completed, this step S32 is repeated.

In step S33, the ID information and the like received in step S32 are answered to the traveling vehicle.

Next, in step S34, it is determined whether or not the traveling vehicle is traveling toward the entrance of the ETC gate 1. If the traveling vehicle is in the entrance, the process proceeds to step S35. If not in the entrance direction, step S38
To go to.

In step S35, it is determined whether or not the use start condition based on the ETC, for example, the ID information and the bank account number is satisfied, and if the condition is satisfied, Is Step S36
On the other hand, if not established, the process ends.

In step S36, information on the traveling vehicle is recorded in the ETC database. This information includes, for example, the use start date and time, the name of the entering interchange, and the like.

Then, in step S37, a forced stop signal is transmitted to the traveling vehicle.

On the other hand, in step S38, it is determined whether or not the traveling direction of the traveling vehicle is the exit direction of the gate.
On the other hand, if it is not the exit direction, it ends as an error.

In step S39, information recorded on the IC memory card 27 of the traveling vehicle, for example, the name of the entry interchange, is received. Then, in step S310, the information is used based on the information received in step S39. Process the amount of money. In this processing, the confirmation of the usage fee, the usage fee, the usage start date and time, the usage section information, etc.
In step 39, the information is collated with the information on the traveling vehicle received.

In step S311, if the result of collation with the ETC database is OK, the process proceeds to step S312, and if not, the process ends.

In step S312, a forced stop signal is transmitted to the traveling vehicle, and then in step S313, it is determined whether or not the payment of the fee has been completed. If the payment is completed, the process ends. If the payment is not completed, the process proceeds to step S314.

In step S314, it is determined whether or not the traveling vehicle has passed through the ETC gate 1. If the traveling vehicle has passed through the gate, the process proceeds to step S315 to transmit a restart prohibition signal to the traveling vehicle. Send
On the other hand, when the vehicle does not pass through the gate, step S31
Repeat step 4. The traveling vehicle is ETC
The determination as to whether or not the vehicle has passed through the gate 1 is made, for example, by the above-mentioned ETC.
A camera is installed near the gate 1 and judgment is made from the image of the vehicle taken by this camera, or a plurality of discharge tubes or sensors are arranged along the ETC lane, and time-series detection by the discharge tubes or sensors is performed. The passage of the vehicle may be captured based on the result to determine whether the vehicle has passed the ETC gate 1 or not.

Next, the processing of the vehicle-mounted ETC unit 2 will be described with reference to the flowchart shown in FIG. 7 or FIG.

In FIG. 7, steps S41 to S412, and in FIG. 8, step S413
Steps S420 to S420 are performed by the ETC unit 2 in the first embodiment.
Since these steps are the same as steps S11 to S120 and step S124, description thereof is omitted (see FIG. 3 or FIG. 4).

Then, in step S420,
When the forced stop signal on the ETC gate 1 side cannot be received and the process proceeds to step S421, the process proceeds to step S42.
In step 1, it is determined whether or not the restart prohibition signal from the ETC gate 1 has been received. If not received, the process proceeds to step S422 to set the engine stop signal to a low level. On the other hand, if it has been received, the process proceeds to step S423, where the engine stop signal is set to Hig.
h level.

The processing in the automatic engine stop unit 3 is the same as the processing in the automatic engine stop unit 3 in the first embodiment (see FIG. 5).

Then, in the case of “part 1”, in the case of the entrance side, a forced stop signal is transmitted from the entrance side antenna transmitter 13 of the ETC gate 1 as in the first embodiment,
By receiving this forced stop signal, both the engine stop signal and the valid signal from the ETC unit 2 are Hi.
