The ROM 12A stores pump characteristic curves and calculation procedures (calculation formulas) based thereon.
第２図には、32屯ダンプトラツク塔載エンジン
の回転数と燃料消費量と出力の関係を表わす特性
曲線が示してある。 FIG. 2 shows a characteristic curve representing the relationship between the rotational speed, fuel consumption, and output of a 32-ton dump truck tower-mounted engine.
この特性曲線を用いれば、エンジン回転数と燃
料消費量とから前記ダンプトラツクの場合の正確
なエンジン出力を求めることができる。 Using this characteristic curve, it is possible to determine the accurate engine output for the dump truck from the engine speed and fuel consumption.
即ち、エンジン出力は基本的にエンジンの燃料
消費量によつて決定されるため、該消費量を計測
すれば、その時点でのエンジン出力が判明する。 That is, since engine output is basically determined by the amount of fuel consumed by the engine, by measuring the amount of fuel consumed, the engine output at that point in time can be determined.
その結果をエンジン回転数で除すれば、エンジ
ンの出力トルクまたは平均有効圧力の推定も可能
である。 By dividing the result by the engine speed, it is also possible to estimate the engine output torque or average effective pressure.
かかる事由から、エンジン系の総負荷は次式で
求めることができる。 For this reason, the total load of the engine system can be calculated using the following formula.
ｑ∝PS＝Ｋ・Pme・Ｎ ……(i)
（ｑ：燃料消費量、PS：エンジン出力、Pme：平
均有効圧力、Ｎ：エンジン回転数、Ｋ：エンジン
個有の定数）
従つて、上述のエンジン特性曲線と(i)式がエン
ジン系ROM１１Ａに記憶される。 q∝PS=K・Pme・N...(i) (q: fuel consumption, PS: engine output, Pme: average effective pressure, N: engine speed, K: constant unique to the engine) Therefore, the above The engine characteristic curve and equation (i) are stored in the engine system ROM 11A.
一方、ポンポ系ROM１２Ａには、第３図に示
す如きポンプ特性曲線と下記演算式(ii)が記憶され

即ち、油圧補機系については、ポンプ吐出油の
圧力と流量およびポンプ駆動効率（機械効率）が
判明すれば、その系統の正確な負荷（消費馬力）
を推定できる。 In other words, for a hydraulic auxiliary system, if the pressure and flow rate of the pump discharged oil and the pump drive efficiency (mechanical efficiency) are known, the exact load (horsepower consumption) of that system can be determined.
can be estimated.
従つて、上記第３図のポンプ特性曲線を用いれ
ば、補機系負荷を次式(ii)によつて求めることがで
きる。 Therefore, by using the pump characteristic curve shown in FIG. 3 above, the auxiliary system load can be determined by the following equation (ii).
PS＝ＰＱ／η ……(ii)
（PS：補機系消費馬力、Ｐ：油圧力、Ｑ：圧油流
量、η：機械効率や容積効率等の全効率）
この場合の圧油流量Ｑはエンジン１で駆動され

から圧油流量Ｑを求めることができる。 PS=PQ/η...(ii) (PS: auxiliary system horsepower consumption, P: hydraulic pressure, Q: pressure oil flow rate, η: total efficiency such as mechanical efficiency and volumetric efficiency) In this case, the pressure oil flow rate Q is Since it is proportional to the rotation speed of the pump 2 driven by the engine 1, the pressure oil flow rate Q can be determined from the rotation speed.
なお、ポンプ系の使用油の粘性は補機駆動に必
要な馬力に大きく影響するので、前記補機系負荷

す油温を充分に考慮する必要がある。このため、
補機系ROM１２Ａには、油の温度と粘度の特性
基準データをも記憶させておく。 The viscosity of the oil used in the pump system greatly affects the horsepower required to drive the auxiliary equipment, so when estimating the load on the auxiliary equipment system, it is necessary to fully consider the oil viscosity and the oil temperature that affects the viscosity. There is. For this reason,
The auxiliary system ROM 12A also stores characteristic reference data of oil temperature and viscosity.

is the sensor 3 to 5 of each system when the vehicle is operating.
By inputting the signals from and 6 to 8,
Each characteristic curve and calculation equations (i) and (ii) are read out from the ROM 11A, 12A of each system, and the input signal from the sensor is processed based on the characteristic curve using the equation. As a result, the total load of the engine system and the load of the auxiliary equipment system are calculated individually. In this case, the arithmetic processing mechanism 12 of the auxiliary system uses the input signal from the oil temperature sensor 8 when calculating the load of the same system to ROM12A.
Since oil viscosity correction is performed by reading the oil characteristic reference data from , the auxiliary system load calculated as described above becomes an accurate value after oil viscosity correction.
