2. Description of the Related Art A conventional vehicle is disclosed in, for example,
As disclosed in Japanese Patent Application Laid-Open No. 5444 (A61G 5/02), for example, an emergency switch is provided in a case where an emergency or emergency situation is set in which a body of a wheelchair is provided with lighting, a signal light, a voice synthesis speaker or a horn so that the user cannot move. When the light is turned on, a light and a signal light blink, or a warning is given by loudspeaker and horn by voice from a speaker, thereby constituting a means for notifying the user as well as surrounding people of the emergency.

[0003] However, with the above-described configuration, an alarm is issued when the emergency switch is turned on and no alarm is issued when the emergency switch is turned off. If the motor temperature rises on a rough hill and the motor continues to run, the motor will break down and stop if the emergency switch is not turned on, and an alarm notifying the abnormality will not be issued unless the emergency switch is turned on. Therefore, the user may continue running and damage the motor. Also, if the emergency switch is turned on, an alarm will be issued even in a light state that does not disturb the main body even if you continue running, so the user may feel discomfort because the alarm may be harsh. I could feel it.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle which always informs a user or a surrounding person of an abnormality of a main body.

[0005]

According to the present invention, there is provided a driving device for driving a driving wheel provided on a main body, an accelerator for instructing a driving force of the driving device, and a driving device for driving the driving device based on the instruction of the accelerator. A driving means for outputting a driving signal for performing the operation, a state detecting means for detecting a state of the main body, and a notifying means for notifying the state detected by the state detecting means, and the magnitude of the output of the notifying means is provided. A changeover switch for setting is provided, and the notifier outputs a predetermined output when the main body is in a specific state regardless of the setting of the changeover switch.

With the above arrangement, the driving device is driven and travels by the instruction of the accelerator. When an abnormality occurs in the main body and the state detecting unit detects the abnormal state identified, the notifying unit sets the output of the changeover switch to a small output, or the user feels that the notification is overhearing. Even when the changeover switch is turned off, the output set by the changeover switch does not notify the user with the determined output, but the user can know only the specific state by the notification and the user can know the specific state. In any state other than the state of, no notification is made, so that it is difficult to feel discomfort such as a touch.

A driving device for driving driving wheels provided in the main body, an accelerator for instructing a driving force of the driving device, and a driving signal for driving the driving device based on the instruction of the accelerator are output. A driving unit, a state detecting unit for detecting a state of the main body, and a notifying unit for notifying a state detected by the state detecting unit from an alarm sound and a sound indicating the state, and a magnitude of an output of the notifying unit. And a notifying switch that outputs only an alarm sound when the setting of the changeover switch is set to off.

With the above arrangement, the driving device is driven and travels by the instruction of the accelerator. When an abnormality occurs in the main body, the state detecting unit detects the abnormality, and the notifying unit outputs only an alarm sound even if the user feels the notification to be jarring and turns off the changeover switch. In addition, the user can know the abnormality by the alarm sound, and does not notify the voice, so that the discomfort such as a noise can be reduced.

Further, the state detecting means discriminates between a danger warning for which traveling must be prohibited and other cautionary warnings, and the notifying means determines the state of the danger warning regardless of the setting of the changeover switch. When the main body travels on a steep slope and the temperature of the motor rises and continues to travel as it is, the motor is broken down and the travel is performed. The state of the main body detected by the state detection means is determined to be a danger state in which the danger state in which disabling is not possible and the caution state in which the main body is not hindered immediately after traveling is continued. For example, the notifying means does not notify the output set by the changeover switch even if the changeover switch is set to a small output, or the changeover switch is turned off when the user feels uncomfortable. Since notified by-determined output, together with the user alarm of only dangerous state of the body is able to know for sure, when the attention state, nothing less likely to feel the discomfort, such as harsh because it does not alarm.

The state detecting means distinguishes between a danger warning in which traveling must be prohibited and a caution warning other than the danger warning, and the notifying means sets a changeover switch when notifying the caution warning. Since only the alarm sound is output when set to off, if the state of the main body detected by the state detecting means is the caution state, the notifying means outputs only the alarm sound. Even if the user feels the sound to be unpleasant and turns off the change-over switch, the user can know the cautionary state by the alarm sound, and since the sound is not reported, the discomfort such as the unpleasantness is reduced. be able to.

Further, a driving device for driving driving wheels provided on the main body, an accelerator for instructing a driving force of the driving device, and a driving signal for driving the driving device based on the instruction of the accelerator are output. Driving means, state detecting means for detecting the state of the main body, and a notifying means for notifying the state detected by the state detecting means from an alarm sound and a sound indicating the state, the state detecting means, the traveling A danger alarm that must be prohibited and a caution alarm other than that are discriminated, and the notifying unit outputs a predetermined output when the danger alarm is in a state even when the changeover switch is turned off, and When the caution warning is issued, only a warning sound is output.

With the above arrangement, the driving device is driven to run by the instruction of the accelerator. When an abnormality occurs in the main body, the state detection means detects and determines the abnormality,
If the determination is the danger state, the notification means is set by the changeover switch even if the changeover switch is set to a small output or the changeover switch is turned off even if the user feels the sound to be jarring. A predetermined output, such as the alarm sound and the voice, is output without notification, and if the caution state is issued, only the alarm sound is output. It is possible to reliably determine whether the user is in a caution state or not, and in the caution state, the voice is not notified, so that discomfort such as noise can be reduced.

[0013] The notifying means may include: a magnitude of an output at the time of the danger warning when the setting of the changeover switch is off;
Since the magnitude of the output at the time of the caution warning when the setting of the changeover switch is the maximum is made the same, even if the user feels the sound to be aggressive and turns off the changeover switch. If the state of the main body detected by the state detection means is the dangerous state, the notification means,
Since the output is the same as the maximum output set by the changeover switch that is output when the caution state is detected, the user can surely know the danger warning without overlooking it, and Actions can be taken to avoid the situation.

Then, when the accelerator lever 12 is operated, the vehicle starts running based on the operation amount. At this time, if the traveling direction switch 9a is on the forward side,
If the vehicle is on the reverse side, the vehicle travels in the reverse direction.

When the vehicle starts traveling, the traveling direction and traveling speed are input from the encoder 23, and it is determined whether the traveling direction and the traveling direction are the same as the signal from the traveling direction switch 9a and whether the speed is higher than the speed indicated by the accelerator lever 12.

When restarting, the power switch 11 is turned "OFF" and then turned "ON" again, so that power from the battery 13 is supplied.

Next, the operation of the state detection circuit 27 will be described with reference to FIG.

In this embodiment, the types of states that occur in the main body 1 are the danger states in which traveling must be prohibited,
It is divided into two groups with other attention states,
The type of alarm is such that the danger state is a danger alarm and the caution state is a caution alarm. These alarms are constituted by a combination of an alarm sound such as “beep” or “boo” and a sound that announces the state by sound. These audible alerts will sound "boo" when it is difficult to continue driving.
When a mere warning is given, a warning sound of a "beep" sound is issued, and then a sound indicating each state is output.

Next, a specific description will be given of how the state detection circuit 27 announces a sound when the state of the main body 1 is in the caution state.

When the vehicle is traveling in the reverse direction by switching the direction change switch 9a to the reverse side, a signal in the reverse direction is input from the encoder 23, and a reverse warning alarm, that is, a sound indicating a warning alarm after an alarm sound "pipi" from the audio speaker 29. "I'm going back."

When a load is applied to the motor 21 and the current of the motor 21 increases, for example, when the vehicle runs on a steep uphill, a motor current detection circuit (not shown) for detecting the current is provided with a predetermined current. When the state is detected to be higher than the value, the state detection circuit 27 determines that the state is the caution state, and
From 9, a warning warning of climbing, that is, a warning sound "Beep", followed by a warning sound "Sudden uphill. You can not run for a long time" is issued.

When the power switch 11 is turned on while the accelerator lever 12 is operated, if the signal from the accelerator input circuit 19 and the signal from the power switch 11 are simultaneously input to the microcomputer 18, the state detection circuit 27 is determined to be a caution state, and a power switch operation error caution alarm is issued from the audio speaker 29, that is, a sound indicating a caution alarm after the alarm sound "beep", "Return the accelerator lever and turn on the power switch again." .

When the power switch 11 is turned on and a charging plug (not shown) is inserted, the battery 1
3 and the AC voltage from the commercial power supply are input at the same time, the state detection circuit 27 determines the caution state,
The voice speaker 29 issues a charging operation error caution alarm 1, that is, a sound indicating a caution alarm after the alarm sound “beep”, “Turn off the power switch and re-insert the charging plug.”

Further, the power switch 11 is turned on during charging.
In this case, since the DC voltage from the battery 13 and the AC voltage from the commercial power supply are simultaneously input, the state detection circuit 27 determines that the state is cautionary, and the charging operation error warning alarm 2 from the audio speaker 29, that is, the alarm sound “ After the beep, a warning sound is sounding, "Charging is in progress. Turn off the power switch."

When a battery voltage monitoring circuit (not shown) for monitoring the voltage of the battery 13 is lower than a preset voltage, the state detection circuit 27 determines that the state is a caution state, A low-warning warning, that is, a warning sound "beep" followed by a warning sound "battery low. Recharge."

When the vehicle cannot travel with the performance of the motor 21 due to excessive load, the current of the motor 21 increases. Therefore, a motor current detection circuit (not shown) detects a value higher than a preset current value. State detection circuit 27
Is judged as a caution state, and an overload caution warning is issued from the voice speaker 29, that is, a voice sound indicating a caution warning is issued after the warning sound "beep""Motor power is insufficient."

Next, the announcement of the sound when the state is dangerous will be described in detail.

When a temperature sensor (not shown) for detecting the temperature of the motor 21 detects a value higher than a preset temperature, for example, when a load is applied to the motor 21 and the motor 21 is overheated, a state detection circuit is provided. 27 is determined to be in danger,
The voice speaker 29 issues a motor overheat danger warning, that is, a warning sound "boo" followed by a danger warning sound "The motor has become hot. After a short rest, please run."

If a control box (not shown) containing a control circuit such as the microcomputer 18 is overheated for some reason, the electronic components may be damaged by the heat. When a temperature sensor (not shown) detects a value higher than a preset temperature, the state detection circuit 27 determines that the state is dangerous, and issues a warning from the audio speaker 29 to the control box overheating danger, that is, an alarm sound “boo”. Followed by a danger warning sound "The control box has become hot. Rest for a while and then drive."

Further, when the encoder 23 fails and the motor 2
If the rotation of the motor 1 is not detected and the traveling speed is not input to the microcomputer 18, the speed cannot be controlled to the set speed, so that the state detection circuit 27 determines that the vehicle is in a dangerous state. Followed by a danger warning sound "The motor is running abnormally. Contact your dealer."

When the motor drive circuit 22 fails and the power generation braking of the motor 21 is not applied, when the encoder 23 detects the number of rotations of the motor 21 and determines that the speed cannot be controlled to the set speed, the state detection circuit 27 turns on. It is determined that the vehicle is in a danger state, and the voice speaker 29 issues a speed danger alarm 2, that is, a warning sound "beep" followed by a danger warning sound "The motor speed is abnormal. Contact your dealer."

If the potentiometer 20 or the accelerator input circuit 19 fails and the rotation of the motor 21 cannot be controlled, the encoder 23 detects the rotation speed of the motor 21 and determines that the speed cannot be controlled to the set speed. The detection circuit 27 determines that the state is dangerous, and the sound speaker 29
Then, a speed danger warning 3, ie, a warning sound "boo" followed by a danger warning sound "The speed does not reach the predetermined speed. Please contact your dealer."

Further, when the electric circuit for controlling the main body 1 fails, the state of the operation cannot be controlled, so that the state detection circuit 27 determines that the operation is in danger. "", A danger warning sound "The control circuit is abnormal. Please contact your dealer."

The relationship between the above-mentioned alarm and the alarm switch 10 will be described.

In the case of the caution alarm, when the alarm changeover switch 10 is set to OFF, only the alarm sound is issued at an output smaller than the maximum output. The indicated sound is emitted at an output smaller than the maximum output, and when the sound is set to be large, the alarm sound and the sound indicating the state are emitted at the maximum output. That is, the alarm changeover switch 1
It is output as set to zero.

In the case of a danger alarm, an alarm sound and a sound indicating the state are issued at the maximum output regardless of the setting of the alarm switch 10.

More specifically, when the alarm changeover switch 10 is set to the off position and, for example, the vehicle travels backward by switching the direction changeover switch 9a to the reverse side, a signal in the reverse direction is input from the encoder 23 and the audio speaker From 29, only the reverse warning, that is, the warning sound "beep" is issued with an output smaller than the maximum output set by the large value of the alarm changeover switch 10.

When the alarm changeover switch 10 is set to a small value, for example, when the direction changeover switch 9a is switched to the reverse side and the vehicle travels in the reverse direction, a signal in the reverse direction is input from the encoder 23, and the state detection circuit 27 It is determined that the vehicle is in the caution state, and the voice speaker 29 emits a backward caution warning, that is, a warning sound "beep" followed by a sound indicating the state "back."

Further, when the alarm changeover switch 10 is set to a large value, for example, when the direction changeover switch 9a is switched to the reverse side and the vehicle travels in the reverse direction, a signal in the reverse direction is input from the encoder 23, and the state detection circuit 27 It is determined that the vehicle is in the caution state, and a reverse caution warning is issued from the voice speaker 29, that is, a sound “backing up” indicating the state is issued after the warning sound “beep” with the maximum output set by the warning changeover switch 10.

Further, a description will be given of an announcement of a voice when the state is dangerous.

When the state detection circuit 27 detects that the state of the main body 1 is in a dangerous state, for example, when the motor 21 is loaded on a steep uphill for a long time and a load is applied to the motor 21 to cause the motor 21 to overheat and break down, an alarm is issued. Regardless of the setting of the change-over switch 10, a motor overheating danger alarm from the audio speaker 29, that is, an alarm sound "boo", and a sound indicating the state "The motor has become hot. It is emitted at the maximum output set by the changeover switch 10.

In the present embodiment, the alarm sound and the sound are emitted from the audio speaker.
For example, a horn may be used. In this embodiment, a motor is used as the driving device, but an engine may be used.

As described above, when an abnormality occurs in the state of the main body 1, the state detection circuit 28 detects the abnormality, and even if the alarm changeover switch 10 for notifying the state is off, the predetermined state is determined only when the specified abnormal state occurs. Since the notification is made by the output, there is an effect that the user can notice the specific state of the main body 1.

When the alarm changeover switch 10 is set to small or large, an alarm sound and a sound indicating the state are output to notify an abnormal state.
When 0 is set to off, only the alarm sound is output, so that the user can be surely aware of the abnormality of the main body 1, and since the sound is not output, the discomfort such as tingling can be reduced. effective.

The state detecting circuit 27 discriminates an alarm for notifying a state occurring in the main body 1 into a danger alarm in which the traveling must be prohibited and a caution alarm in other cases. Even if the switch 10 is turned off, the user is notified with a predetermined output, so that the user can notice that the main body 1 is in a dangerous state.

Further, an alarm for notifying a state generated in the main body 1 is classified into a danger alarm in which the state detection circuit 27 must prohibit traveling and a caution alarm other than the above. Even if the switch 10 is turned off, only the alarm sound is output, so that the user can notice that the main body 1 is in the caution state, and since the sound is not output, it is possible to reduce the discomfort such as tingling. effective.

Further, even if the alarm changeover switch 10 is turned off, an alarm sound and a sound indicating the state are output in a danger state, and only an alarm sound is output in a caution state. Can determine whether the state of the main body 1 is a danger state or a caution state, and in the caution state, since the sound is not output, an unpleasant sensation such as noise can be reduced.

Further, the output of the danger alarm when the alarm changeover switch 10 is turned off is the same as the output of the cautionary alarm set by the alarm changeover switch 10 to a large value. Be sure to be aware of the fact that you are not overlooked, and if the user is in danger of being unable to move, notify the user as well as the surrounding people of an alarm and receive relief. There are effects such as being able to. Further, when designing the output of the alarm, there is an effect that the configuration can be simplified.

A changeover switch for setting the value, and the notifying means, when the main body is in a specific state, outputs a predetermined output irrespective of the setting of the changeover switch. When the state detecting means detects the specified abnormal state, the notifying means does not notify with the output set by the changeover switch even if the changeover switch is set to a small output or set to off. The user can be notified of the abnormality by the notification because the output is determined in the above-mentioned manner. The effect of regret, and the like.

According to a second aspect of the present invention, there is provided a state detecting means for detecting a state of the main body, and a notifying means for notifying a state detected by the state detecting means from an alarm sound and a sound indicating the state, A changeover switch for setting the magnitude of the output of the notifying means is provided, and the notifying means outputs only an alarm sound when the setting of the changeover switch is turned off. Then, the state detecting means detects the abnormality, and the notifying means outputs only an alarm sound when the changeover switch is set to off, so that even if the changeover switch is set to off, the user is notified. Has the effect that the abnormality can be known by the alarm sound, and the sound is not reported, so that discomfort such as noise can be reduced.

According to a third aspect of the present invention, the state detecting means distinguishes between a danger warning for which traveling must be prohibited and a caution warning other than the warning, and the notifying means determines whether or not the changeover switch is set. In the case of the danger alarm state, a predetermined output is output. Therefore, if the state of the main body detected by the state detection means is the danger state, the notification means turns off the changeover switch. Even if the setting is not made, the output set by the changeover switch is not notified but a predetermined output is notified, so that the user can surely recognize the danger state, and at the time of the caution state, Also, since it does not notify the user, it has the effect of making it difficult for the user to feel unpleasant sensation such as a feeling of harshness.

According to a fourth aspect of the present invention, when notifying the caution alarm, the notifying means outputs only an alarm sound when the setting of the changeover switch is turned off. If the state of the main body detected by the means is the caution state, the notification means outputs only an alarm sound, so that the user can reliably recognize the caution state even when the changeover switch is off. In addition, since the voice is not notified, it is possible to reduce an unpleasant sensation such as noise.

According to a fifth aspect of the present invention, the notifying means outputs a predetermined output when the danger alarm is in effect even when the setting of the changeover switch is off, and notifies the caution alarm. When the state of the main body detected by the state detection means is the danger state, the notification means sets the output of the changeover switch to a small output, or turns off the state. Even if the setting is made, the output set by the changeover switch outputs a predetermined output without notification, for example, an alarm sound and a voice, and if the caution state is given, only the alarm sound is output. The person can reliably determine whether the abnormality of the main body is a danger state or a caution state, and in the caution state,
Since the voice is not notified, an effect such as a reduction in discomfort such as noise can be achieved.

According to a sixth aspect of the present invention, the notifying means is configured to output the magnitude of the output at the time of the danger alarm when the setting of the changeover switch is off, and to provide the caution when the setting of the changeover switch is maximum. Since the magnitude of the output at the time of the alarm is the same, even when the changeover switch is set to off, if the state of the main body detected by the state detection means is the danger state, the notification means is Since the output is the same as the maximum set by the changeover switch that is output when the caution state is detected, the user can reliably know the danger state of the main body, and the user can take a motion. When the vehicle is in an extremely dangerous state, not only the user but also the surrounding people can be alerted and relieved.
