Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traffic management device for obtaining information regarding the operating status of a motor vehicle.

As the price of fuel refined from petroleum resources rises, the proportion of fuel costs in the operating costs of commercial vehicles equipped with diesel engines is increasing.For example, in the case of route trucks, the proportion of fuel costs is increasing. It has reached about 80%. Under these circumstances, automobile manufacturers are making various improvements to engines and vehicles to improve fuel efficiency. However, if the operation manager does not perform appropriate maintenance, or if the driver does not take care to drive in a way that improves fuel efficiency, fuel efficiency will deteriorate and costs will increase.

In view of these problems, traffic control devices have been proposed especially for commercial vehicles. The purpose of this device is to provide the driver with data to enable economical driving, and to provide the operation manager with data to manage economical driving. Furthermore, information regarding the timing of maintenance can also be provided. This device uses a microcomputer, and the microcomputer processes various detected values such as the engine rotational speed detected by the sensor, and outputs the data using an output device such as a printer. And conventional methods such as this (J management device calculates the amount of fuel consumed, the frequency of use in each rotational speed range of the engine, or the distribution of the frequency of use of each stage of the transmission, etc.) I have to.

Therefore, with such a conventional traffic control device, it has not been possible to detect the state of the parts operated during driving operation. In other words, it is not possible to detect the operating status of various devices installed in a car, such as service brakes, exhaust brakes, clutches, starters, and coolers, and therefore it is not always possible to obtain complete information about the operating status of the car. The drawback was that it could not be done. In particular, the use of the service brake and exhaust brake has a large impact on engine fuel efficiency and maintenance timing, so it is preferable to reliably detect and notify the user.

The present invention has been made in view of these problems, and it is an object of the present invention to provide a traffic control device that reliably obtains information regarding the state of the parts that are activated during driving operations. This is the purpose.

The present invention will be explained below with reference to an illustrated embodiment.

FIG. 1 shows an automobile operation control apparatus according to this embodiment, and this operation control apparatus is composed of a microcomputer 1. As shown in FIG. The microcomputer 1 is equipped with an input port 2 through which the microcomputer 1 is connected to a battery 3 mounted on a vehicle. Further, the input port 2 is connected to a key switch 4. The key switch 4 is connected to the battery 3 via a battery relay 5. A battery switch 6 is connected to the battery relay 5 in order to control the battery relay 5.

Furthermore, the microcomputer 1 is connected to an engine rotation sensor 7 via an input port 2. The rotation sensor 7 is provided, for example, in an alternator 8 installed in the engine. Further, the microcomputer 1 constituting this operation management device is connected to a vehicle speed sensor 9 via an input port 2, and is configured to read information regarding vehicle speed. Furthermore, the microcomputer 1 is connected to a pair of fuel gauges 10.11. The fuel side 10 is designed to measure the amount of fuel supplied, while the other fuel meter 11 is designed to measure the amount of fuel returned. Further, a detection horn of a load sensor 12 is supplied to the microcomputer 1 via an input boat 2. Load sensor 1
Reference numeral 2 includes a sensor that detects, for example, the angle of the load lever of the fuel injection pump of this engine.

A service brake switch 13 is connected to the ON contact of the key switch 4. This switch 13 is connected in series with the brake lamp 14, and is opened when the brake pedal is depressed, causing the brake lamp 14 to blink. A terminal is taken out from the connection point between the switch 13 and the lamp 14, and this terminal is connected to the input port 2. Furthermore, the ON contact of the key switch 4 is connected to a series circuit of a clutch switch 15, an exhaust brake switch 16, a control switch 17, and an electromagnetic valve 18.

A terminal is taken out from the connection point between the control switch 17 and the coil of the pulp 18, and this terminal is connected to the input port 2 of the microcomputer 1. Further, another clutch switch 19 is connected to the input port 2 of the microcomputer 1. Furthermore, input port 2 is connected to thermo unit 20,
This thermo unit 20 detects the water temperature of the engine and supplies the information to the microcomputer 1. Further, a thermo gauge 21 is connected to the ON contact of the key switch 4.

Furthermore, the ON contact of the key switch 4 is the cooler switch 2.
2 and a magnet switch 23, and by opening and closing the cooler switch 22, the magnet switch 23 is controlled and the cooler is turned on and off. A connection point between the switch 22 and the magnet switch 23 is connected to the input port 2. Further, the microcomputer 1 has a printer 24.
is connected to. This printer 24 constitutes an output device of the microcomputer 1, and is used to output various data.

Next, we will explain the operation of the vehicle operation control system configured as described above. This operation control device uses a pair of fuel units to reduce the amount of fuel used by 3.
The microcomputer 1 calculates the usage amount to calculate the fuel consumption, and the printer 14 prints out the fuel consumption. Further, according to this operation control device, the engine rotation speed is measured by the engine rotation sensor 7 provided in the alternator 8, and this value is subjected to -C calculation processing by the computer 1, thereby determining the engine rotation speed. I'm trying to get all kinds of information.

Furthermore, this traffic control device reads the vehicle speed using a vehicle speed sensor 9 and processes the data obtained by the sensor 9 using the computer 1 to obtain various information regarding the vehicle speed.

Furthermore, this operation control device counts the number of times each of the service brake, exhaust brake, clutch, starter, and cooler are used. The service brake usage status is determined by the service brake switch 13.
The state of exhaust brake use is obtained by the outputs of three switches 15, 16, 17, the state of clutch use is obtained by clutch switch 19, and the state of cooler use is obtained by cooler switch 22.
It is now detected by. The detection output of the sensor consisting of these switches is supplied as an interrupt signal to the microcomputer 1 through the input port 2, and when one of these interrupt signals is supplied, the result shown in FIG. The counting is performed based on the flowchart shown.

To explain this operation in more detail, the service brake,
If one of the exhaust brake, clutch, starter or cooler is activated, this will cause the CP
A signal will be supplied to the interrupt control signal input port of the LII.

In other words, the microcomputer 1 determines whether the vehicle is currently traveling in a city area or on an expressway.

This determination is made by detecting the switching state of a switch (not shown) installed in the traffic management device. Then, for each of the city area and the expressway, it is determined from the combination of the read signals whether the signal is a service brake signal, exhaust brake signal, clutch signal, starter signal, or cooler signal. If the corresponding signal is confirmed, the count is incremented by one. This allows for accurate counting of the number of times each service brake, exhaust brake, clutch, starter, and cooler are used. Moreover, since the above-mentioned counting is carried out for the city area and the expressway, it is possible to more accurately know the usage status of each of these parts.

Furthermore, in the traffic control device according to the present embodiment, not only the number of times the exhaust brake and the cooler are used but also the length of time they are used are measured. The usage time of the exhaust brake is counted based on the flowchart shown in FIG. 3, and when the three switches 15, 16, and 17 shown in FIG. The exhaust brake will be switched to the active state. Therefore, the microcomputer 1 reads this state and starts counting time from this point. Then, when one of the three switches 15.1'6.17 opens, the voltage at the output of the switch 17 decreases, so in this state it is detected that the exhaust brake is OFF, and the above-mentioned time is counted. I'm trying to stop it. Therefore, the time during this period becomes the operating time of the exhaust brake.

Similarly, regarding the cooler, the time during which the cooler switch 22 is closed is measured according to the flowchart shown in FIG. 1, that is, when the cooler switch 22 is closed, the microcomputer 1 starts counting time, and when the cooler switch 22 is turned off, it stops counting the time. The operating time of the cooler is then counted from this time. Furthermore, regarding the car cooler, the usage time of the car cooler relative to the operating time is calculated by dividing the cumulative usage time by the operating time. Therefore, it becomes possible to reliably grasp the state in which the car cooler is being used.

Although the present invention has been described above with reference to the illustrated embodiment, the present invention is not limited to the above-described embodiment, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiment, a service brake, an exhaust brake,
The microcomputer 1 counts the number of times each clutch, starter, and cooler are used, and the results are printed out by the printer 24, but the portions counted in the present invention are not necessarily limited to these portions. It is also possible to replace some or all of these parts with other parts.

As described above, the present invention relates to an automobile operation control device that is provided with a sensor that detects the state of a part that is activated during driving operations, etc., and that counts the number of detection operations of this sensor. be. Therefore, according to the present invention, it becomes possible to reliably count the number of times a part that is activated during a driving operation or the like is used, and it becomes possible to obtain more detailed information regarding the operating state of the automobile.
