DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle traveling information collecting apparatus, and more particularly to a vehicle traveling information collecting apparatus for accurately determining that a vehicle is traveling at a low speed on a congested road and measuring a low traveling time. .

[0002]

2. Description of the Related Art Conventionally, a vehicle running information collecting apparatus for automatically collecting the running state of a bus or a business truck, particularly for automatically measuring a low speed running time on a congested road, has a configuration shown in FIG. That is, a display operation unit 1 which is a man-machine interface with a crew member, a vehicle speed sensor 2, a computer (CPU) 3 for executing various arithmetic control processes,
It comprises a recording unit 4 for recording vehicle running information, and a display / operation unit 1 and interfaces (I / F) 5 and 6 between the vehicle speed sensor 2 and the computer 3. Then, the computer 3 acquires the traveling speed of the vehicle from the vehicle speed sensor 2 via the interface 6, obtains the traveling speed at each time with respect to this time axis, and outputs the traveling speed to the recording unit 4.

[0003]

However, in such a conventional vehicle running information collecting device, if even a running pulse is input from the running sensor 2 for one second, the one second is regarded as running and the running time is counted as one second. When the cumulative time reaches 60 seconds, the running time is counted as 1 minute, so the low-speed running such as 10 km / h is also included in the running time, and the low-speed running time is actually running on a congested road. However, there is a problem that it cannot be distinguished from the output of the recording unit 4 whether the vehicle is deliberately driven at a low speed due to the crew's illegal time gain even though the road is vacant.

[0004] The present invention has been made in view of such conventional problems. When the vehicle is traveling at a low speed, it is counted as a traveling time only when the traveling time is unavoidable due to traffic congestion. It is an object of the present invention to provide a vehicle traveling information collecting device that prevents a low-speed traveling for illegal time gain by preventing the vehicle from running into time.

As the proximity sensor 12, a radar device that transmits a search signal in the forward direction, measures the distance from the reflected signal to the target ahead, and uses an ultrasonic signal, a radio signal, a laser light signal, or the like is used. Used. Further, the sensor may be configured so that a reflected signal of a signal transmitted to a target ahead of a certain distance can be received, and when the reflected signal is received, the inter-vehicle distance is determined to be within the reference distance. .

As the vehicle speed sensor 22, a vehicle speed sensor for a speedometer mounted on a vehicle is usually used.

FIG. 2 shows a functional configuration of a program executed by the computer 16 for judging illegal low-speed running.
The proximity sensor signal input unit 21 for inputting the proximity detection signal a from the proximity sensor 12, the vehicle speed sensor signal input unit 22 for inputting the vehicle speed detection signal b from the vehicle speed sensor 13, and the memory 15 A reference value setting unit 23 that reads out the registered congestion determination reference distance ar and the low speed determination reference speed br and sets them as reference values,

A normal traveling determination unit 26 that determines whether or not the vehicle is traveling at a low speed based on the determination result of the unit 25. When the normal traveling determination unit 26 determines that the vehicle is traveling normally, the traveling speed and the traveling speed It comprises a running time integrating section 27 for integrating running time, and a recording information processing section 28 for creating recording information from the integration result of the running time integrating section 27 and outputting it to the recording section 14.

Next, the operation of the vehicle running information collecting apparatus having the above configuration will be described. In FIG. 1, the crew performs a necessary input operation on information displayed on the display operation unit 11. To collect actual vehicle travel information, the inter-vehicle distance signal a from the proximity sensor 12 and the vehicle speed signal b from the vehicle speed sensor 12 are input to the computer 16, and the congestion determination reference distance ar registered in the memory 15 by the computer 16 in advance. In comparison with the low-speed reference speed br, while traveling at a speed exceeding the low-speed reference speed, data is plotted on a graph with the travel time on the horizontal axis and the travel speed on the vertical axis, and this is recorded in the recording unit. Record at 14. When traveling at a vehicle speed b lower than the low-speed traveling reference speed br, the proximity sensor 1
Only when the inter-vehicle distance a detected by the vehicle 2 is smaller than the traffic congestion determination reference distance ar, the traveling time is accumulated and recorded by the recording unit 14.
To record.

The running time integrating process executed by the computer 16 is as follows. That is, in FIG.
The reference value setting unit 23 stores the traffic congestion determination reference distance a from the memory 15.
r, the low-speed travel determination reference speed br is read and the traffic congestion determination unit 2
4. Pass it to the low-speed running determination unit 25.

The congestion determination unit 24 compares the inter-vehicle distance a between the vehicle and the preceding vehicle input from the proximity sensor 12 through the proximity sensor signal input unit 21 with the congestion determination reference distance ar, and determines the actually measured inter-vehicle distance a as the congestion determination reference distance. If it is larger than ar, it is determined that the road is not congested and it is empty, and if the measured inter-vehicle distance a is smaller than the congestion determination reference distance ar, it is determined that the road is congested, and a congestion determination signal is output. c is output to the normal traveling determination unit 26.

The low-speed running determination unit 25 compares the vehicle speed b input from the vehicle speed sensor 13 through the vehicle speed sensor signal input unit 22 with the low-speed running reference speed br, and when the measured vehicle speed b is higher than the low-speed running reference speed br. Judge as normal running,
When the measured vehicle speed b is lower than the low speed reference speed br, it is determined that the vehicle is running at low speed, and a low speed running determination signal d is output to the normal running determination unit 26.

The normal traveling judging section 26 does not receive the low speed traveling judging signal d from the low speed traveling judging section 25, receives the traffic jam judging signal c from the traffic jam judging section 24, and receives the low speed traveling judging signal from the low speed traveling judging section 25. Only when the vehicle receives the low speed driving signal d, the normal traveling determination signal e is output to the traveling time integrating unit 27. And does not output the normal traveling determination signal e.

The running time integrating section 27 outputs a normal running determination signal e.
While receiving, the time to receive the measured vehicle speed b is integrated,
The vehicle speed data and the accumulated time data are passed to the recording information processing unit 28.

In the recording information processing section 28, the traveling time integrating section 2
From the vehicle speed data and the travel time data given from 7, the data in the form of a tachograph having a horizontal axis on the time axis and a vertical axis on the vehicle speed is created, output to the recording unit 14, and recorded by the recording unit 14.

By the above processing, the low-speed running reference speed b
The time during which the vehicle is traveling at a speed higher than r is integrated as the normal traveling time during the low-speed traveling, and the recording time is recorded by the recording unit 14.
Therefore, when a crew member intentionally drives at a low speed on an empty road in order to gain time, the time is not counted as a running time, but is recorded as a stopped time (that is, from the manager side). As a result, it is recorded as a pause time, so that an intention of earning a traveling time by illegally traveling at a low speed can be defeated, and illegal low-speed traveling can be prevented.

The procedure for collecting the above-mentioned vehicle traveling information will be described in more detail with reference to the flowchart of FIG. As shown in FIG. 4, if the vehicle on which the vehicle traveling information collecting device of the present invention is mounted is A and the vehicle B is ahead of it, the traveling time during low-speed traveling is counted based on the inter-vehicle distance n. Will be determined. Then, 15 m is set as the traffic congestion determination reference distance X, and 10 km / h is set as the low speed traveling reference speed Y. When the vehicle stops without traffic congestion, for example, when it stops at a traffic light, the vehicle enters a low speed traveling state. The number of times Z to repeat the congestion state determination process is twice, and the time interval T for repeating the congestion determination is
Is set to 2 seconds.

The processing in the flowchart of FIG.
For example, it is repeatedly executed every 5 seconds. First, the traffic jam determination reference distance X (= 15 m) and the low-speed reference speed Y (= 10 km)
/ h), the number of times of congestion determination Z (= 2 times), the weight time T (=
2 sec) is read and stored (step S1,
S2).

Next, it is determined from the vehicle speed signal whether the vehicle is running or stopped (step S3). If the vehicle is stopped, the process exits once without performing the running time integration. If the vehicle is running, the speed is calculated from the vehicle speed signal input as a pulse signal (step S4), and the low speed reference speed Y is calculated.
(= 10 km / h) and the actual speed V (step S
5).

In the speed comparison in step S5, if the actual speed V is higher than the low speed reference speed Y (= 10 km / h), it is regarded that the vehicle is traveling normally, the traveling time is integrated, and the process exits once (step S8). .

If the actual speed V is equal to or less than the low speed reference speed Y (= 10 km / h) in the speed comparison in step S5, it is determined that the vehicle is running at low speed, and then the inter-vehicle distance n is determined based on the proximity sensor signal.
Is calculated (step S6), and the measured inter-vehicle distance n is compared with the set value X (= 15 m) of the traffic jam determination reference inter-vehicle distance (step S7). In this comparison, if the measured inter-vehicle distance n is smaller than the set value X (= 15 m), the inter-vehicle distance with the preceding vehicle B is small, and it is determined that the vehicle is traveling at low speed because the vehicle is really congested, and the traveling time is integrated ( Step S8).

However, in the inter-vehicle distance comparison in step S7, the inter-vehicle distance n is equal to the traffic congestion determination reference inter-vehicle distance X (=
If it is larger than 15m), it means that the vehicle has entered the low-speed operation because it is about to stop due to a signal or an obstacle at hand, or whether it is deliberately driving at a low speed to gain traveling time. Assuming that there is, after entering the low-speed running state, it is determined whether or not to stop within a certain wait time T (= 2 sec).

Therefore, when the vehicle enters the low-speed running state for the first time, Z = 2.
Then, a wait of T = 2 sec is performed by the timer (steps S10 and S11), and then it is determined whether or not the operation has stopped again (step S3). If the operation has not stopped, the speed calculation is executed again (step S4), and the actual speed V If the vehicle travels at a low speed, the inter-vehicle distance n is calculated again (steps S5 and S6), and compared with the traffic congestion determination reference distance X again (step S7).

In the second comparison in step S7, if the actual inter-vehicle distance n is smaller than the traffic congestion determination reference distance X, it is determined that there is congestion, and the process branches to step S8 to accumulate the travel time. However, if no congestion determination is made even in the second comparison, Z = Z in step S9.
In step S10, the flow branches to YES, and the process exits without accumulating the travel time. That is, it is determined that the vehicle is traveling unnecessarily at low speed even though there is no traffic congestion, and the low speed traveling time is not included in the actual operation traveling time.

As a result, even if the vehicle travels intentionally at a low speed in order to earn the traveling time, the recorded time is recorded as a stop time. It will be possible to prevent earning time.

In the above-described embodiment, a sensor that measures the distance between vehicles is used as the proximity sensor. However, a sensor that detects the presence of a target in front of the vehicle when the target approaches a certain distance may be used. The various reference values set in the above embodiment are not particularly limited, and can be set to other numerical values.

[0030]

As described above, according to the present invention, when the vehicle is traveling at a low speed, the vehicle is regarded as actually traveling at a low speed due to traffic congestion only when the inter-vehicle distance to the preceding vehicle is smaller than a predetermined reference value. Since the time is accumulated, if the crew is deliberately traveling at low speed in order to earn the traveling time without congestion, the time is not accumulated as the traveling time, and the illegal traveling time is earned. Can be prevented.
