This invention relates to a driving data recording device for +P vehicles such as collection and delivery vehicles that stores and collects the travel time required for each intersection and collection and delivery destination while performing collection and delivery operations.

[Conventional technology]

Nowadays, traffic congestion is a serious social problem, and it is important to inform people how to get to their destination in the shortest possible time! be caught.

This is an even more serious problem in the multi-wheel drive industry, where the key to profitability is how efficiently a vehicle can be moved. It's decided.

However, with the rapid development of information and communication technology in recent years, it is possible to use these to predict the time required between a departure point and a destination, or choose the shortest estimated time from among multiple routes. A system for selecting one is being developed by the Automotive Electronics Technology Association.

Until 06, sign posts were placed at major points on roads such as intersections from A to F, and received and demodulated radio waves corresponding to the identification number of each vehicle sent from vehicles passing nearby. , outputs the identification number to computer 110. 107 to 109 are vehicles, each of which is equipped with a radio, and each vehicle has an assigned identification number (
code) and is emitted.

The computer 110 reads passing vehicle information at sign post installation points such as intersections 101 to 106,
Calculate the travel time between the signposts of the vehicle, and store that time as it is or the average value with past data for the same section in the storage area for each section in the memory tit.
Store. That is, by reading the contents of this memory 111, it is possible to know the time required to travel each X interval Itj.

[Problem that the invention seeks to solve]

By the way, such conventional vehicle operation data recording systems are configured to measure the travel time required for each road section by installing signposts on the road and receiving radio waves emitted from the vehicle. Therefore, a huge amount of social investment is required to install signposts, and they cannot be used in areas where signposts are not installed. Especially when used in the collection and delivery industry, it is important to collect data on the travel time required from the intersection to the collection and delivery business location, but it is not possible to set up a sign post for each collection and delivery business location. ,
The problem was that it was not possible to collect important data such as the distance from the intersection to the collection and delivery business location.

The present invention has been made with attention to such problems, and allows for the recording of vehicle operation data without the need to install signposts on roads or the like. 1 (Operation record that can record operation data while estimating the own vehicle position using vehicle position detection means installed in the vehicle! IC)
This was done for the purpose of providing a convenient location.

[Failure to solve the problem]

Suekan IJJ includes a vehicle position detection means that detects that the vehicle is located at each predetermined point on the travel route and outputs a position detection signal, and a vehicle position detection means that detects that the vehicle is stopped and outputs a stop detection signal. a vehicle stop detection means for stopping the vehicle at a work place and performing work, a work end signal output means for outputting a work end signal after the vehicle is stopped at a work place, a time measuring means for outputting measured time data, and a memory for storing input data. and a temporary storage means for sequentially replacing and storing only the latest input data, while the data obtained based on the time data when the position detection signal or the end of work signal is input,

The response means and the transfer means that transfer the stop time data stored in the temporary storage means to the storage means in response to the input of the work end signal as the arrival time data of the two cars are transferred to the storage means in response to the input of the work end signal. It is something that

[Effect]

■1 (When the vehicle is running, when the vehicle position detection means detects that the vehicle is located at a predetermined point on the route, it outputs a position detection signal. Then, the signal/time correspondence The means sends data obtained based on time data when the position detection signal is input to the storage means as vehicle passing time data, and the sent vehicle passing time data is stored in the storage means.

When a vehicle stops due to traffic congestion or a traffic signal, the vehicle stop detection means outputs a stop detection signal, and the signal/stop signal is output.
The time correspondence means sends data obtained based on the time data when the stop detection signal is input to the temporary storage means as ilj both stop time data. The vehicle stop 1 (time data is temporarily stored in the temporary storage means until the next new vehicle stop time data is input. At the work place when the vehicle is stopped at the work place and the work is carried out) Unlike the stopping time of a vehicle while it is in motion, it is relatively long, and it is not appropriate to incorporate it into the vehicle's driving time when analyzing entrainment data. Therefore, in the present invention, after the work at the work place is finished, the work end signal output means outputs the work end signal and sends it to the signal/time correspondence means and the transfer means. The signal/time correspondence means sends data obtained based on the time data when the work end signal is input as the departure time of the vehicle from the work place to the storage means as work place arrival data.It also inputs the work end signal. The transfer means transfers the latest stoppage data from last month stored in the temporary storage means to the storage means as the vehicle's arrival time data at the business location.In this way, the storage means has information about each point on the travel route. Vehicle passing time data, arrival time data at the business location, and departure time data from the business location will be recorded.

〔Example〕

FIG. 2 is a block diagram showing the equipment configuration according to the embodiment of the present invention. Reference numeral 5 denotes an Ilt-based computer system, which includes a CPU 6 for controlling the system, an interface 7 and 8 for connection with attached devices, a memory (RAM) 9 used as a storage stage, a ROM 10, and the like.

The Tosa computer system 5 is connected via an interface 7 to a heavy speed sensor 1 for keeping the vehicle speed constant at A, a direction sensor 2 such as a geomagnetic sensor, and a clock 3 for measuring time and outputting time data. Further, the on-vehicle computer system 5 is connected via an interface 8 to a collection/delivery completion record switch 4 that outputs an electrical signal as a service completion signal indicating the completion of the collection/delivery service.

As shown in FIGS. 3 to 5, the memory (RAM) 9 includes a memory T, a memory E, and a memory P. As shown in FIG. 3, the memory T stores data such as the time when the vehicle passes a predetermined point, which is measured by the clock 3. Of these, the NO and O areas are areas for storing the vehicle speed 0, that is, the external time of the vehicle, and are used to temporarily store input data until the next new time data is input. After the NO, l area, the passing time of a predetermined point, the arrival time at the collection/delivery destination as a business location, and the departure time from the collection/delivery destination are stored.

As shown in FIG. 4, the memory E is a memory for storing the collection and delivery destination codes for which the collection and delivery service has been completed, and the fact that the collection and delivery service has been completed is sequentially stored for each case. Memory P is the fifth
As shown in the figure, this is a data memory for the planned travel route for each day, and stores in advance the coordinates of one planned passage point and the necessary data for the distance of the section. Therefore, the memory 9 can be freely accessed from the on-vehicle computer 5.

Here, vehicle speed sensor 5. The direction sensor 6, the memory P in the memory 9, and the program/software of the CPU 6 constitute a vehicle position detection means, which detects by calculation etc. that the vehicle passes a point determined by the memory P, and detects the position at that time. Output a signal. CPU6 and its programs
The software configures a stage corresponding to the signal and time, and the position detection signal.

The business end signal from the collection/delivery end record switch 4 or 11 (
When the stop/start detection signal from the speed sensor 1 is input, the time data of the input 11ν is sent to the storage means as vehicle passing time data, business location IIIi time data, or business location arrival data, respectively. Vehicle speed sensor l is ilj both stopped l
J detecting means outputs a stop detection signal when the vehicle speed is O. In addition, the collection/delivery end record switch 4 constitutes a business end signal output means, and the program/software of the CPU 6, register memory, memory (RAM) 9, memory 10, etc. constitute storage means and temporary storage means, and the CPU
The program φ software within constitutes a transfer means.

As described above, the on-vehicle computer system 5 calculates the current position of the vehicle by inputting the detected zero values from the heavy speed sensor 1 and Q sensor 2, and inputs the current position of the vehicle into IIJ1 at a predetermined time. It controls the storage of time data in the area, completes collection and delivery operations, and controls recording.

Next, the operation of this embodiment will be explained. Figure 6 shows the planned travel route of the vehicle shown in Figures 3 to 5, starting from collection and delivery center C, passing from intersection PI through P2 to P3, and arriving at collection and delivery destination AI as a business location. Do your business and cross the intersection P4. This shows the route passing through P5 and reaching the collection/delivery destination A2 as a business location, and is stored in the memory P in FIG.

The departure time of center C is stored in area No. 1 of memory T in FIG. The departure time is the first 11 (vehicle speed generation time) detected by the vehicle speed sensor l after the start of this system. This is done by comparing the current position η detected by the sensor 6 with the data in the memory P in the memory 9. If they match, a position detection signal is output, and the signal/corresponding means outputs the position detection signal when the signal is input. Time data, namely Pl.

P2. P3 passing time t2. t3. t4 is N of memory T
・1(
It is sent as both passing time data.

By the way, the dead reckoning method 11 (detection of both positions by the +p speed sensor 5 and the direction sensor 6 accumulates errors, so the calculated current position may deviate from the actual position, and it is difficult to judge whether to pass through an intersection. takes the midpoint between the time when the vehicle enters and exits a predetermined range (for example, a circle) centered on the coordinates of the intersection and stores it in memory, and when turning left or right at an intersection, the direction of the vehicle changes at a predetermined angle. It is assumed that the passing time data is stored in the memory using the following method.

The NO, 0 area of memory T is the stop 1 (
This is an area where time data is stored one after another.

For example, as shown in Fig. 7, when the dE cars temporarily stop f- due to waiting at a traffic light before the intersection P3, the vehicle speed sensor serving as the vehicle stop detection means detects the stop +1 (stop time data ts when inputting the detection 0). is stored in the N000 area of the memory T as a general storage means, as shown in FIG. 8 (&), and is retained even after the ilf issuance 41j.

Eventually, as shown in Figure 7, collection and delivery destination A1 as a business location was established.
When the vehicle arrives at ili speed O, the stop time data t5 at the time of inputting the stop detection signal output from the di speed sensor 1 is sent from the time correspondence means to the temporary storage means, and ts
and is stored in the NO, 0 area as shown in FIG. 8(b). As shown in Figure 7, the vehicle must be stopped for a relatively long time at the collection/delivery destination for business operations such as loading, unloading, and VC customers. If there is a traffic jam,
As described above, due to automatic position detection with errors, it is not possible to specify the time of arrival at the collection/delivery destination as a business location.

Collection/delivery end recording switch 4 as end of work Y signal output means
As shown in Fig. 7, is turned on every time the work at each collection/delivery destination is completed, so that the service end signal is output, and the business bond r at the collection/delivery destination as the corresponding business location is activated. Memory E
is stored in

At that time, No. 41) of memory T, which has temporarily lost its memory.
, Stop-1 (time data ts stored in area O)
is the same memory T as a storage means, area No. 5 (area for storing the arrival time at the collection and delivery destination A1 as a business location)
The time of arrival at A1 is determined as ts, as shown in FIG. 8(C).

The departure time from the collection/delivery destination A1 as a business location is the time when the electric signal (-) as a business end signal outputted by turning on the collection/delivery completion record switch 4 is input into the time correspondence means. Alternatively, for more precise measurement, the first output from the vehicle speed sensor 1 after the pickup/delivery end record switch is turned on +l (the time when the signal was received, that is, the time when the vehicle speed occurred) may be set as 6, and as a storage means. It is stored in the No. 6 area of memory T. In this case,
Also, the end-of-service r signal output means is the vehicle speed sensor l.

Thereafter, in the same way, the intersection passing time data, the arrival of the collection and delivery destination as a business location, and 9. East time data is stored in memory T. After the vehicle returns to the center C, the memory 9 is
It is removed from the IN computer system and read out the stored data on a stationary computer, calculates the required section time from the time data and creates a database, and also completes the collection and delivery work performed on that day. Perform processing, etc.

〔Effect of the invention〕

As explained above, according to one aspect of the present invention, the configuration is as follows: - The time when the F vehicle most recently stopped is stored in the temporary storage means;
When there is a work end signal, the time is stored in the storage means as the time when the vehicle arrived at the work place, so even if a dead reckoning type vehicle position detection means is used, the accurate time of arrival at the work place can be measured. can do. That is, the present invention can record accurate operation data at low cost without installing expensive equipment such as sign posts.
