Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an overspeed monitoring system that warns when a vehicle exceeds a predetermined speed, and more particularly to an overspeed monitoring system that can warn a taxi or the like with an appropriate warning message according to the presence or absence of a passenger.
[0002]
[Prior art]
When a driver drives a taxi or other business vehicle, he or she must pay a fine, but at the same time the company responsible for managing the driver is also held accountable. Therefore, the company needs to take measures to prevent drivers from speeding.
[0003]
As a method for the driver to voluntarily manage, when the vehicle exceeds a preset speed, the driver is warned by a chime or the like. The driver hears the chime and slows down.
[0004]
Further, as a method of managing the speed excess at the dispatching (management) center, the driver submits a tachograph, which is a running record of the day, to the manager at the end of the work. The administrator checks it and, if necessary, gives instructions on safe driving if there is an overspeed.
[0005]
In addition, as a method of managing and monitoring the speed excess in real time at the dispatch center, speed information is transmitted from the vehicle to the dispatch center in real time. The dispatching center transmits a warning signal (warning sound, warning message) to the vehicle if the speed exceeds the speed limit of the road. Some vehicles receive a warning signal and sound an alarm device.
[0006]
Prior art documents relating to the invention of this application include the following.

[Problems to be solved by the invention]
The method in which the driver voluntarily manages the excessive speed has the advantage that a chime sounds when the vehicle exceeds the set speed, and the driver can be warned in real time. However, there is a problem that the effect is small unless a psychological pressure that someone is being monitored is given to the driver.
[0009]
In addition, the method of managing excess speed using a tachograph, which is a running record, does not know that there is no excess speed but after work is over, and cannot provide guidance. For this reason, there is a problem that the effect is less than when the driver is instructed each time the speed is exceeded. Furthermore, since only the speed information is recorded in the tachograph, there is an ambiguity that even if the speed is excessive on a general road, the speed is not excessive on a highway.
[0010]
In addition, a method of judging excess speed at a dispatch center based on driving information transmitted from a vehicle in real time and immediately sending a warning signal to the vehicle is effective when a driver exceeds the speed. There is an advantage that you can teach each time. However, in a taxi or the like, there is a problem that when a customer (passenger) is on board, giving an effective warning of "ping pong / speeding off" will cause discomfort to the passenger.
[0011]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and can provide an effective warning in real time when a speed is exceeded, and prevent an uncomfortable warning even when a customer (passenger) is on board. The task is to
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is an overspeed monitoring system that monitors an overspeed of a vehicle based on traveling information of the vehicle, wherein a passenger detection unit that detects presence or absence of a passenger of the vehicle, Excess speed detection means for detecting that the vehicle has exceeded a predetermined speed, and when the excess speed detection means detects that the vehicle has exceeded a predetermined speed, the presence or absence of a passenger detected by the passenger detection means A warning means for outputting different warning information in response to the request is provided.
[0013]
The over-speed monitoring system includes a vehicle, and a management center that monitors the vehicle based on traveling information obtained from the vehicle. The vehicle transmits traveling information of the vehicle and information on the presence or absence of a passenger. Transmitting to the management center, when the management center detects that the vehicle has exceeded a predetermined speed based on the received traveling information, different warning information is given to the vehicle based on the received passenger presence / absence information. The vehicle transmits and outputs the received warning information.
[0014]
The overspeed monitoring system includes a vehicle and a management center that monitors the vehicle based on traveling information obtained from the vehicle, and the vehicle transmits traveling information of the vehicle to the management center. And, when the management center detects that the vehicle has exceeded a predetermined speed based on the received traveling information, the management center transmits overspeed information to the vehicle, and the vehicle receives the overspeed information. At this time, different warning information is output based on the presence / absence information of the passenger detected by the passenger detection means.
[0015]
Further, when the excess speed detection means detects that the vehicle has exceeded a predetermined speed, and the passenger detection means detects the presence of a passenger, the warning means sets the presence of the passenger. After outputting the warning information based on the information, when the passenger detecting means detects the absence of the passenger, another warning information is output again.
[0016]
Further, when the excess speed detecting means detects that the vehicle has exceeded a predetermined speed, and the passenger detecting means detects the presence of a passenger, the warning means includes the passenger detecting means. Delays the output of the warning information until the vehicle detects the absence of a passenger.
[0017]
In addition, the warning means outputs the warning information even when the vehicle once exceeds a predetermined speed and then falls below a predetermined speed.
[0018]
Further, the excess speed detecting means determines the predetermined speed based on road type information indicating a type of a road such as a general road or an expressway.
[0019]
In addition, the vehicle has map information including road type information, and the speed excess detection unit includes a road type detection unit that detects a road type of a road where the vehicle exists based on the map information and the position information of the vehicle. It is characterized by having.
[0020]
Further, when the excess speed detecting means determines that the road type detected by the road type detecting means is different from the road type selected by the driver, the excessive speed detecting means requests the driver to correct the road type. It is characterized by the following.
[0021]
Further, if the road type is not corrected within a predetermined time after requesting the driver to correct the road type, the excess speed detecting means may set the road type independently. It is a feature.
[0022]
Further, the warning information includes a warning method and / or a warning content, and the warning means outputs the different warning information by a warning method such as voice output, display, and vibration.

[0026]
Next, a method of outputting a warning message will be described with reference to the flowcharts of FIGS. In this embodiment, the vehicle side transmits traveling information such as vehicle speed information, position information, road type information, door opening / closing information, actual vehicle / vacant vehicle information to a dispatch center, and the dispatch center transmits the vehicle information based on the map information. The traveling road is specified and the excess speed is constantly monitored, and when the vehicle exceeds the speed, an appropriate message according to the actual vehicle state or the empty state is transmitted to the vehicle in real time. This process (both in FIGS. 2 and 3) starts when the operation switch of the in-vehicle device 1 is turned on (usually, leaving the warehouse and starting a job), and when the operation switch of the in-vehicle device 1 is turned off (usually, It is repeatedly executed until receiving and ending the work.
[0027]
First, the processing performed by the processing device 11 on the vehicle side will be described. In step S11, initial setting is performed, and the process proceeds to step S12. That is, the memory of the vehicle-mounted device 1 is cleared.
[0028]
In step S12, traveling information and operation information of the vehicle are detected, and the process proceeds to step S13. That is, the open / close sensor 13 determines the open / closed state of the door, the open / closed state of the door (open to closed, closed to open), the speed of the vehicle with the vehicle speed sensor 14, and the position of the vehicle with the GPS receiver or the like of the position detection unit 15. The road type signal output unit 16 detects the type of the road on which the vehicle is currently traveling from the selection switch operated by the driver, and the actual vehicle / empty vehicle detection unit 19 detects the actual vehicle / empty vehicle.
[0029]
In step S13, it is determined whether or not it is the transmission timing, and if it is the transmission timing, the process proceeds to step S14, and if not, the process returns to step S12. The transmission timing of information from the vehicle to the dispatch center is (1) when a predetermined time has elapsed (each time), (2) when the vehicle has traveled a predetermined distance (every time), and (3) there is a transmission request from the dispatch center. Time (polling method), (4) when the road type changes, (5) when the door opening / closing state changes, (6) when the actual vehicle / empty state changes, etc., are preset.
[0030]
In step S14, the travel information is edited and transmitted to the dispatch center, and the process proceeds to step S15. Edited in a format that can transmit various information necessary to determine whether or not a warning message is generated at the dispatch center, for example, car number information, time information, road type information already detected, position information, Vehicle speed information, actual vehicle / vacant vehicle-specific information, door open / close state information, information indicating the start and end of transmission, and the like are added. Then, the edited information is transmitted to the center device 2 of the dispatch center via the communication unit 12.
[0031]
In step S15, it is determined whether a road type confirmation request has been received. If a road type confirmation request has been received, the process proceeds to step S18. If a road type confirmation request has not been received, the process proceeds to step S16. The request for confirmation of the road type is sent to the dispatching center when it is determined that the type of the road specified by matching with the map information 23 on the basis of the received vehicle position information does not match the received road type information. 2 is a signal transmitted for reconfirmation to the vehicle side. No signal is transmitted when the road types match between the two.
[0032]
In step S16, it is determined whether a warning message has been received. If a warning message has been received, the process proceeds to step S17. If no warning message has been received, the process returns to step S12. The warning message is a signal output from the center device 2 to the vehicle when it is determined that the speed of the vehicle is exceeding the speed at the dispatch center. The speed (predetermined speed) serving as a reference for comparison is set in advance to, for example, 100 km / h for a highway and 50 km / h for a general road.
[0033]
In step S17, a warning message is output, and the process returns to step S12. That is, the warning message received from the dispatch center is output to the warning unit 17. The warning message is composed of an appropriate warning sound and a warning message depending on whether the vehicle is an actual vehicle or an empty vehicle at the dispatch center. For example, in the case of an actual vehicle, a gentle warning sound and warning message such as "Let's drive at a safe speed" with consideration for passengers, and in the case of an empty vehicle, an effective warning sound such as "Ping-pong / speeding driving" etc. The warning message and the re-warning are a warning sound and a warning message such as "Ping-pong, speeding has just been performed." Further, in the case of an actual vehicle, the volume of the warning sound or the warning message may be made slightly smaller than that of an empty vehicle in consideration of the passenger. Further, in the case of an actual vehicle, a warning may be issued so that the passenger is not noticed by blinking display or vibration of a lamp instead of voice.
[0034]
In step S18, a confirmation of the road type is requested, and the process returns to step S12. That is, the road type calculated based on the vehicle position and the map information at the dispatch center side does not match the road type input by the driver. Please select again. "(Voice output or display).
[0035]
Next, processing performed by the processing device 21 on the dispatch center side will be described. In step S31, initial setting is performed, and the process proceeds to step S32. That is, the memory of the center device 2 is cleared.
[0036]
In step S32, it is determined whether or not the travel information has been received. If the travel information has been received, the process proceeds to step S33. If the travel information has not been received, the process waits. When the travel information is received, an acknowledgment indicating that the travel information has been normally received is returned to the vehicle.
[0037]
In step S33, the position information and the dynamic information are updated, and the process proceeds to step S34. That is, based on the received information, the road type information, the position information, the vehicle speed information, the actual vehicle / vacant vehicle-specific information, the door open / close state information, and the like recorded in the memory of the dispatch center are updated.
[0038]
In step S34, it is determined whether or not the vehicle position and the road type match, and if the vehicle position and the road type match, the process proceeds to step S35, and if the vehicle position and the road type do not match. Move to step S49. The road where the vehicle exists is specified by matching with the map information based on the vehicle position information received at the vehicle distribution center. Then, it is determined whether or not the identified road type (regular road or expressway) matches the received road type information. The road type mismatch may occur when the driver does not change the road type each time when the vehicle moves from a general road to an expressway, or vice versa.
[0039]
In step S35, it is determined whether or not the flag is 1, and if the flag is 1, the process proceeds to step S45. If the flag is not 1 (the flag is 0), the process proceeds to step S36. This flag 1 is set when there is an overspeed but there is a passenger in the actual vehicle, so that it is not possible to give a very effective warning to the driver and it is necessary to give a warning again when the passenger gets off later. is there.
[0040]
In step S36, it is determined whether or not the speed has been exceeded. If the speed has been exceeded, the process proceeds to step S37. If not, the process returns to step S32. When the speed of the vehicle received at the dispatching center exceeds a preset speed, for example, 100 km / h on a highway and 50 km / h on a general road, it is determined that the speed is excessive. It should be noted that whether the speed is an instantaneous speed or an average speed within a predetermined time is set in advance in order to exclude the influence of overtaking (acceleration).
[0041]
In step S37, it is determined whether the vehicle is an actual vehicle or an empty vehicle. If the vehicle is an actual vehicle, the process proceeds to step S38. If the vehicle is empty, the process proceeds to step S42. This determination is made to differentiate the warning given to the driver depending on the presence or absence of a passenger. In other words, the distinction is made so as to give a gentle warning in consideration of the passenger when the vehicle is an actual vehicle, and to issue an effective warning when the vehicle is empty because there is no passenger.
[0042]
In step S38, "message A" is transmitted, and the routine goes to step S39. The “message A” is a gentle warning in consideration of the passenger, and is composed of, for example, only a warning sound such as “beep-beep-beep” or a warning sound such as “Let's drive at a safe-beep-beep-safe speed” and a warning message.
[0043]
In step S39, it is determined whether or not the flag is 1, and if the flag is 1, the process proceeds to step S41. If the flag is not 1 (the flag is 0), the process proceeds to step S40.
[0044]
In step S40, the flag is set to 1 and the process proceeds to step S41. Although there was an overspeed, the driver was not able to give a very effective warning due to the presence of passengers in the actual vehicle. Then, the flag is set to 1 in order to warn again when the passenger gets off later.
[0045]
In the step S41, the reception information and the warning information are recorded, and the process returns to the step S32. That is, reception information and warning information are recorded in order to grasp the driving situation of each driver at the dispatch center. Then, when the operation switch of the in-vehicle device 1 is turned off (usually, when the vehicle enters the warehouse and the operation is completed), the daily driving safety report is printed as shown in FIG. Based on the recorded information, it is possible to individually instruct a driver who has a large number of speed overruns.
[0046]
In step S42, "message B" is transmitted, and the routine goes to step S43. "Message B" is an effective warning when there is no passenger, and includes, for example, a warning sound such as "Ping-Pong / Speeding Driving" and a warning message.
[0047]
In step S43, it is determined whether or not the flag is 1, and if the flag is 1, the process proceeds to step S44. If the flag is not 1 (the flag is 0), the process proceeds to step S41.
[0048]
In step S44, the flag is set to 0, and the routine goes to step S41. Since there is no speed and there is no passenger in the empty vehicle, an effective warning can be given to the driver, and the flag is set to 0 since there is no need to give a warning again.
[0049]
In step S45, it is determined whether the vehicle is an actual vehicle or an empty vehicle. If the vehicle is empty, the process proceeds to step S46. If the vehicle is an actual vehicle, the process proceeds to step S36. In other words, the driver was not able to give a very effective warning because there was a passenger in the actual vehicle, though there was a speed excess before. Therefore, it is necessary to give a warning again when the passenger gets off, in order to determine the timing.
[0050]
In step S46, it is determined whether or not it has been detected that the door has changed from the open state to the closed state. If the door changes from the open state to the closed state, the process proceeds to step S47, where the door changes from the open state to the closed state. If not, wait. Even when the vehicle is vacant (at the time of operating the toll meter), there is a risk that the passenger is still inside the vehicle. Therefore, it is confirmed that the passenger has gone out of the vehicle by the door changing from the open state to the closed state. Note that, in this step, instead of detecting that the door has changed from the open state to the closed state, it may be detected that a predetermined time has elapsed since the door became empty.
[0051]
In step S47, "message C" is transmitted, and the routine goes to step S48. "Message C" is a warning again, and is composed of a warning sound such as "Ping-pong, speeding just before" and a warning message.
[0052]
In step S48, the flag is set to 0, and the routine goes to step S41. Since the driver was warned again, the flag is set to 0.
[0053]
In step S49, a confirmation request is transmitted, and the routine goes to step S50. That is, since the road type transmitted from the vehicle side does not match the road type calculated based on the vehicle position and the map information 23 on the dispatching center side, for example, the "confirm road type" Please select again. "
[0054]
In step S50, it is determined whether or not a predetermined time has elapsed. If the predetermined time has elapsed, the process proceeds to step S51. If the predetermined time has not elapsed, the process waits. The predetermined time is a time required for the driver's confirmation operation, for example, one minute.
[0055]
In step S51, the road type is set on the dispatch center side, and the process proceeds to step S36. That is, since there is no reselection from the vehicle side, the road type is set on the dispatch center side. The setting includes, for example, (1) a general road with a slow speed limit, (2) a road type calculated based on the vehicle position and the map information at the dispatch center side, and (3) a road type selected on the vehicle side. And the vehicle decides.
[0056]
As described above, according to the excess speed monitoring system of the present embodiment, the traveling information can be received from the vehicle, the traveling state of the vehicle can be monitored at the dispatch center, and a warning can be made in real time when the excess speed occurs. Also, at this time, a different warning message is issued depending on the presence or absence of a passenger, so that an appropriate warning can be given to the driver without causing discomfort to the passenger.
[0057]
An overspeed monitoring system according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a flowchart of a process performed by the processing device 11 on the vehicle side of the overspeed monitoring system according to the second embodiment of the present invention. FIG. 6 is a flowchart of a process performed by the processing device 21 on the dispatch center side of the overspeed monitoring system according to the second embodiment of the present invention. In this embodiment, the vehicle transmits traveling information such as vehicle speed information, position information, and road type information to the dispatching center, and the dispatching center identifies the traveling road of the vehicle based on the map information and determines whether the vehicle has exceeded the speed. The vehicle is constantly monitored, and when the vehicle has exceeded the speed, the vehicle transmits, in real time, excess speed (warning) information indicating that the vehicle has exceeded the speed. Upon receiving the warning information, the vehicle creates an appropriate warning message according to the actual vehicle state or the empty state and outputs the message to the warning unit 17. Further, this processing (FIGS. 5 and 6) starts when the operation switch of the in-vehicle device 1 is turned on (usually leaving the warehouse) and continues until the operation switch of the in-vehicle device 1 is turned off (normally enters the warehouse). It is executed repeatedly.
[0058]
First, the processing performed by the processing device 11 on the vehicle side will be described. In step S61, initial setting is performed, and the process proceeds to step S62. That is, the memory of the vehicle-mounted device 1 is cleared.
[0059]
In step S62, the traveling information and operation information of the vehicle are detected, and the process proceeds to step S63. That is, the open / close sensor 13 determines the open / closed state of the door, the open / closed state of the door (open to closed, closed to open), the speed of the vehicle with the vehicle speed sensor 14, and the position of the vehicle with the GPS receiver or the like of the position detection unit 15. The road type signal output unit 16 detects the type of the road on which the vehicle is currently traveling from the selection switch operated by the driver, and the actual vehicle / empty vehicle detection unit 19 detects the actual vehicle / empty vehicle.
[0060]
In step S63, it is determined whether or not it is the transmission timing, and if it is the transmission timing, the process proceeds to step S64, and if not, the process returns to step S62. The transmission timing of the information from the vehicle to the dispatch center is (1) when a predetermined time has elapsed (each time), (2) when the vehicle has traveled a predetermined distance (every time), and (3) when a transmission request is issued from the dispatch center. Time (polling method), (4) when the road type changes, (5) when the door opening / closing state changes, (6) when the actual vehicle / empty state changes, etc., are preset.
[0061]
In step S64, the traveling information is edited and transmitted to the dispatch center, and the process proceeds to step S65. This is edited in a format that can transmit various types of information necessary for judging excess speed at the dispatching center. For example, vehicle type information, time information, road type information, position information, vehicle speed information, and start of transmission , Information indicating the end is added. Then, the edited information is transmitted to the center device 2 of the dispatch center via the communication unit 12.
[0062]
In step S65, it is determined whether or not a road type confirmation request has been received. If a road type confirmation request has been received, the process proceeds to step S79. If no road type confirmation request has been received, the process proceeds to step S66. The request for confirmation of the road type is sent to the dispatching center when it is determined that the type of the road specified by matching with the map information 23 on the basis of the received vehicle position information does not match the received road type information. 2 is a signal transmitted for reconfirmation to the vehicle side. No signal is transmitted when the road types match between the two.
[0063]
In step S66, it is determined whether or not the flag is 1, and if the flag is 1, the process proceeds to step S75. If the flag is not 1 (the flag is 0), the process proceeds to step S67. This flag 1 is set when there is an overspeed but there is a passenger in the actual vehicle, so that it is not possible to give a very effective warning to the driver and it is necessary to give a warning again when the passenger gets off later. is there.
[0064]
In step S67, it is determined whether or not excess speed (warning) information has been received. If excess speed (warning) information has been received, the process proceeds to step S68. If no excess speed (warning) information has been received, the process returns to step S62. . Excess speed information is transmitted from the dispatch center when the speed of the vehicle received at the dispatch center exceeds a preset speed corresponding to the road type.
[0065]
In step S68, it is determined whether the vehicle is an actual vehicle or an empty vehicle. If the vehicle is an actual vehicle, the process proceeds to step S69. This determination is made on the vehicle side so as to make a difference between warnings issued to the driver depending on the presence or absence of a passenger. In other words, the distinction is made so as to give a gentle warning in consideration of the passenger when the vehicle is an actual vehicle, and to issue an effective warning when the vehicle is empty because there is no passenger.
[0066]
In step S69, "message A" is output, and the routine goes to step S70. The “message A” is a gentle warning in consideration of the passenger, and is composed of, for example, only a warning sound such as “beep-beep-beep” or a warning sound such as “Let's drive at a safe-beep-beep-safe speed” and a warning message.
[0067]
In step S70, it is determined whether or not the flag is 1, and if the flag is 1, the process returns to step S62. If the flag is not 1 (the flag is 0), the process proceeds to step S71.
[0068]
In the step S71, the flag is set to 1 and the process returns to the step S62. Although there was an overspeed, the driver was not able to give a very effective warning due to the presence of passengers in the actual vehicle. Then, the flag is set to 1 in order to warn again when the passenger gets off later.
[0069]
In step S72, "message B" is output, and the routine goes to step S73. "Message B" is an effective warning when there is no passenger, and includes, for example, a warning sound such as "Ping-Pong / Speeding Driving" and a warning message.
[0070]
In step S73, it is determined whether the flag is 1 or not. If the flag is 1, the process proceeds to step S74. If the flag is not 1 (the flag is 0), the process returns to step S62.
[0071]
In step S74, the flag is set to 0, and the process returns to step S62. Since there is no speed and there is no passenger in the empty vehicle, an effective warning can be given to the driver, and the flag is set to 0 since there is no need to give a warning again.
[0072]
In step S75, it is determined whether the vehicle is an actual vehicle or an empty vehicle. If the vehicle is empty, the process proceeds to step S76. In other words, the driver was not able to give a very effective warning because there was a passenger in the actual vehicle, though there was a speed excess before. Therefore, it is necessary to give a warning again when the passenger gets off, in order to determine the timing.
[0073]
In step S76, it is determined whether or not it has been detected that the door has changed from the open state to the closed state. If the door changes from the open state to the closed state, the process proceeds to step S77, where the door changes from the open state to the closed state. If not, wait. Even when the vehicle is vacant (at the time of operating the toll meter), there is a risk that the passenger is still inside the vehicle. Therefore, it is confirmed that the passenger has gone out of the vehicle by the door changing from the open state to the closed state.
[0074]
In the step S77, "message C" is output, and the process proceeds to a step S78. "Message C" is a warning again, and is composed of a warning sound such as "Ping-pong, speeding just before" and a warning message.
[0075]
In step S78, the flag is set to 0, and the process returns to step S62. Since the driver was warned again, the flag is set to 0.
[0076]
In the step S79, a confirmation of the road type is requested, and the process returns to the step S62. That is, the road type calculated based on the vehicle position and the map information at the dispatch center side does not match the road type input by the driver. Please select again. "(Voice output or display).
[0077]
Next, processing performed by the processing device 21 on the dispatch center side will be described. In step S81, initial setting is performed, and the process proceeds to step S82. That is, the memory of the center device 2 is cleared.
[0078]
In step S82, it is determined whether or not the travel information has been received. If the travel information has been received, the process proceeds to step S83. If the travel information has not been received, the process waits. When the travel information is received, an acknowledgment indicating that the travel information has been normally received is returned to the vehicle.
[0079]
In step S83, the position information and the movement information are updated, and the process proceeds to step S84. That is, the road type information, the position information, the vehicle speed information, and the like recorded in the memory of the dispatch center are updated based on the received information.
[0080]
In step S84, it is determined whether or not the vehicle position and the road type match, and if the vehicle position and the road type match, the process proceeds to step S85, and if the vehicle position and the road type do not match. Move to step S88. The road where the vehicle exists is specified by matching with the map information 23 based on the vehicle position information received at the vehicle distribution center. Then, it is determined whether or not the identified road type (regular road or expressway) matches the received road type information.
[0081]
In step S85, it is determined whether or not the speed has been exceeded. If the speed has been exceeded, the process proceeds to step S86. If not, the process proceeds to step S87. When the speed of the vehicle received at the dispatching center exceeds a preset speed, it is determined that the speed is excessive.
[0082]
In step S86, "excess speed information" is transmitted, and the routine goes to step S87. Unlike the first embodiment, this information is a signal notifying that the speed has been exceeded, and is not a warning message.
[0083]
In the step S87, the reception information and the warning information are recorded, and the process returns to the step S82. That is, reception information and warning information are recorded in order to grasp the driving situation of each driver at the dispatch center. Based on the recorded information, it is possible to individually instruct a driver who has a large number of speed overruns. Note that, unlike the first embodiment, the information for each actual vehicle / empty vehicle is not transmitted to the dispatch center, so the column for each actual vehicle / empty vehicle is blank.
[0084]
In step S88, a confirmation request is transmitted, and the routine goes to step S89. That is, since the road type transmitted from the vehicle side does not match the road type calculated based on the vehicle position and the map information 23 on the dispatching center side, for example, the "confirm road type" Please select again. "
[0085]
In step S89, it is determined whether or not a predetermined time has elapsed. If the predetermined time has elapsed, the process proceeds to step S90. If the predetermined time has not elapsed, the process waits.
[0086]
In step S90, the road type is set on the dispatch center side, and the routine goes to step S85. That is, since there is no reselection from the vehicle side, the road type is set on the dispatch center side.
[0087]
As described above, according to the excess speed monitoring system of the present embodiment, the traveling information can be received from the vehicle, the traveling state of the vehicle can be monitored at the dispatch center, and a warning can be made in real time when the excess speed occurs. Also, at this time, since a different warning message is created and output on the vehicle side depending on the presence or absence of a passenger, an appropriate warning can be given to the driver without causing discomfort to the passenger.
[0088]
【The invention's effect】
As described above, according to the present invention, a warning can be issued in real time when the speed is exceeded, and an unpleasant warning can be prevented even when a customer (passenger) is on board.
