Abstract

PURPOSE:To enable the suitable data, by which an automobile can perform its economic running, to be given to the driver or the operation controller, by calculating the detection outputs of sensors, which detect the speed of an engine and its load, so as to output the arithmetic result. CONSTITUTION:A microcomputer 10 reads at every second the speed of an engine 1 from a speed detecting sensor 9 while its load from a load sensor 8, storing these data in a corresponding address to a random access memory (RAM) of the computer 10. Then a value of the address is added by one because the data are stored as a frequency, for instance, the speed is divided into ten sections of every 400rpm over the range from 500 to 4,400rpm, while the load is divided into ten sections 10% by 10%. While the frequency of the corresponding address is added one by one in accordance with the speed and the load respectively detected by the sensors 8, 9. In this way, the operating condition of a vehicle is known by printing a content, stored in the RAM10 after the predetermined operation, by a printer 16, and operation improving fuel consumption can be guided on the basis of the operating condition.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile operation control device, and more particularly to an automobile operation control device that measures fuel consumption, etc. in a predetermined driving section.

As the price of fuel refined from petroleum resources continues to rise, the proportion of fuel costs in the operating costs of commercial vehicles equipped with diesel fuel is increasing, rising to about 80% in the case of route trucks. It is said that it will reach Under these circumstances, automobile manufacturers are making various improvements to improve fuel efficiency. However, if the operation manager does not properly maintain the N1 cars, or if the driver does not try to drive in a way that improves fuel efficiency, costs will increase. It turns out.

In view of these problems, we have developed a system that targets commercial vehicles in particular.
:A traffic management device has been proposed. The purpose of this device is to provide the driver with data to enable light driving, and also to provide data to enable economical driving management for traffic control considerations. This device uses a microcomputer to:1. This microcomputer processes the various detection values detected by the sensor and outputs the data using a printer or the like. However, conventional operation control devices of this type only calculate the fuel consumption rate, the usage frequency distribution of engine speed, or the usage frequency distribution of each stage of the transmission, etc. The drawback was that not enough data could be obtained.

There was a vacancy in which no information regarding the negative (I:i) of the S engine could be obtained, without having the If there is a conventional method between stations, there is a lack of proper data to be provided before operation or to the operation manager in order to provide relief 511j. was there.

This invention has been made in view of the above-mentioned problems, and it is necessary to install a sensor to detect the condition of the engine (1) before operation or during operation. 71tn: Shuttle running 1) to provide 11I appropriate data for the flight, U1. 2 self i1', l + luck of the car (

A load (answer 8) consisting of a potentiometer is provided on the surface of the mechanical governor 5, and the load on the engine 1 is detected by this sensor 8.Furthermore, the rotation speed of the crankshaft of the engine 1 is The rotation is detected by a rotation detection sensor 9.These sensors 8.9 are connected to the input ports 1 to 1 of the micro combi coater 10. Connected to the input port of the controller 10 are a car 3-speed switch 11, a fuel switch 12.11, a no-1 switch 1:3, a club switch 1'l, a fuel switch 15, etc. The output side of the microphone coater 10 is connected to the printer 16.

The data is stored in the corresponding RAM address. In this case, in order to store it as El lu, the numerical value of the above address is increased by one.

As shown in Fig. 3, in this embodiment, the rotation speed of one engine 1 is divided into 101 rotations per /IOOrpm from 50 Or't1m to 4400rpm, and the t1 load of engine 1 is It is also divided into 10 wards of 10% each. Therefore, depending on the rotational speed and load of the engine 1 detected by the sensors 8 and 9, the frequency of the corresponding address is added one by one.

0 rllllll is displayed in 10 divisions, but this division may be further divided into 20 divisions. Further, in the above embodiment, the load on the engine 1 is detected by the potentiometer 8 that detects the rotation angle of the load lever 6, but instead of using such a sensor, the load on the engine 1 is detected by the position of the control rack of the fuel injection pump 2. A rack sensor may be used to detect the load on the engine 1, or a sensor may be attached to the accelerator pedal or a link linked thereto to detect the load on the engine 1. Also, the number of revolutions of the crankshaft of the engine 1 (the number of revolutions detected by the rotation detection 1'!n) is 4, but instead of the rotation speed of the alternator, Even if the rotation speed of the engine is detected by attaching it to the terminal 1:=1? However, instead of time-based measurement, distance-based measurement may be used. In this case, the vehicle is detected at a certain distance, for example, 10
