That is, in a system that intensively monitors automobile driving practice at a monitoring center, a plurality of detection means for detecting various driving conditions are provided, and a monitoring data creation means that receives each detection signal is used to monitor automobile driving practice. During the process, multiple types of predetermined timing judgments are made according to the driving conditions of the vehicle, and monitoring data is sequentially created and stored using detection signals from different detection means for each timing. The means is a storage means for storing the monitoring data in chronological order. The stored monitoring data is sequentially transmitted to the monitoring data by the on-vehicle communication means during predetermined communication.

An embodiment of the present invention shown in the drawings will be described below. In the detailed block diagram showing the overall configuration of FIG. 1, numeral 10 is a detection unit that detects various driving states of the training vehicle, 11 is a start switch that issues a training start signal when pressed by the practitioner at the start of driving, and 12 13 is a gear position switch that detects the gear position; 14 is a brake switch that detects brake pedal operation, auxiliary brake pedal operation, or automatic brake operation; 15

Reference numeral 40 denotes a roadside communication unit that transmits communication request specific data and check point designation data to the on-board communication device 30, and receives communication information sent from the on-board communication device 30. The roadside communication unit 41 performs transmission and reception through a large number of roadside loop antennas 42 installed in a loop at each communication point of the driving practice course. A communication point code ID is transmitted from each roadside loop antenna 42.

Reference numeral 50 denotes a central computer installed in the monitoring center, which receives monitoring data indicating driving conditions from the vehicle received by the roadside communication unit 40, judges whether the driving practice is good or bad, and outputs the judgment result. . Reference numeral 51 denotes a processing unit comprised of a computer that executes the calculations, which determines the location and extent of defects in the driving practice based on the monitoring data, and displays the determination results together with the layout pattern of the practice course on the keyboard/display 52. , and is also printed out on the graphics printer 53.

Next, the operation of the above configuration will be explained.

First, at a driving school, when a trainee starts driving practice without an instructor,
Push the start switch 11. As a result, the microcomputer of the in-vehicle processing device 20 starts the arithmetic processing shown in the flowchart of FIG. 2, and the determination at determination step 101 is YES.
, proceed to step 102 to initialize,
The driving status will be automatically monitored.

Then, driving practice of various driving modes on the practice course is started. During the driving practice, each data creation step 107 from steps 103 and 106 in FIG.
~114, each communication point with the roadside loop antenna 42 installed at many locations on the practice course and the distance from that communication point to the next communication point were divided into fixed distances of about several meters. Each division point,
Monitoring data including various driving status data at each point such as a checkpoint point, which is a travel point of a designated check distance, and data at each transition point of driving operation, etc., through communication with each road loop antenna 42. It is created and stored as follows at each creation timing.

a. At the time of communication, communication point data, division point data, point data, and check data (gear position data, derailment data, brake data, rotation speed data, and vehicle speed data) are created and stored in data creation step 107.

b. When passing a dividing point (each point divided at a fixed distance from the communication point), dividing point data is created and stored in step 108.

c When passing a check point (driving point within the specified check distance from the time of communication), the step
109, point data, check point data,
Create and store check data (same as above).

d. When starting the engine, point data, engine stop period data, and check data (gear position data, brake data) are created and stored in step 110.

e When the engine is stopped, in step 111, point data, engine operating period data, and check data (same as above) are created and stored.

f At the time of departure, in step 112 the point data,
Create and store stop period data and check data (same as above).

g When stopped, the point data,
Create and store travel period data and check data (same as above).

h When the contact changes (at the time of transition of various detection switches)
In step 114, point data and corresponding contact data (gear position data, derailment data, or brake data) are created and stored.

This type of data has the following format, which integrates each item code and detection data. That is,
Segment point data is "0000v (4 bits)", v = vehicle speed (4Km/H unit), point data is "001d (5 bits)", d = number of vehicle speed pulses from the latest segment point, communication point data is "010c (5 bits)", c = communication point ID (loop antenna number), check point data is "011p (5 bits)"
So, p = check point ID, gear position data is "10000g (3 bits)",
g = gear position code, brake data is "10001B ₁ B ₂ B ₃ ", B ₁ =
Driver, B ₂ = passenger, B ₃ = automatic, rotation speed data is "1011n (4 bits)", n =
Rotation speed (in units of 200 rpm), vehicle speed data is "0001v (4 bits)", v = vehicle speed (in units of 4 Km/H), engine operation period data is "11000t (3 bits)", t = 0 (0 seconds) , 1 (1 second or more), 2 (2 seconds or more), 3 (3 seconds or more), 4 (4 seconds or more), 5 (5 seconds or more), 6 (10 seconds or more), 7 (20 seconds or more), Engine stop period data is "11001t (3 bits)", t = (same as above), running period data is "11010t (3 bits)", t
= (same as above), stop period data is "11011t (3 bits)", t
(same as above), the derailment data is "1110F ₁ F ₂ R ₁ R ₂ ", where F ₁ = front left wheel, F ₂ = front right wheel, R ₁ = rear left wheel, R ₂ = rear right wheel. ing.

The above-mentioned various monitoring data are stored in chronological order each time they occur.

When the vehicle reaches the end point of the roadside loop antenna 42 after driving practice, it receives a monitoring data request signal through the loop antenna through the calculations in steps 103 and 104 in FIG. In response, the stored monitoring data is sent to the on-board communication unit 3 along with the vehicle number.
1. Sequentially transmit data from the on-board antenna 32 in chronological order to the roadside loop antenna and roadside communication unit 41.
The data is inputted to the processing unit 51 of the monitoring center via step 105, and the arithmetic processing is completed.

The processing unit 51 analyzes and processes the monitoring data, and displays the diagnostic results on the keyboard/display 52 in the format shown in the explanatory diagram of FIG. 3, and also prints them out on the graphic printer 53.

This diagnosis result clearly indicates a defective gear position G and a derailment point W on the layout pattern of the practice course.

Therefore, the driving situation of the trainee can be automatically diagnosed without the need for an instructor to accompany the driver during driving practice, and the location and extent of the driving defect can be objectively clarified. The labor of the instructor can be greatly reduced.

In the above-described embodiment, the monitoring data created and stored in the on-vehicle processing device 20 is sent to the monitoring center at the end point position. may be sent out sequentially.

As described above, according to the present invention, a plurality of predetermined timing determinations are performed according to the driving situation of the car during driving practice by a trainee, and different detection means are used for each timing depending on the timing. Monitoring data is created and stored sequentially using the detected signals from the driver, so after the driving practice is completed, the monitoring data is automatically analyzed and the instructor is on hand to assess whether the driving situation is good or bad. This has the excellent effect of making it possible to automatically and objectively judge the situation without any problems, and to improve the efficiency of driving practice.
