Engine control method and control device
First Claim
1. A method of controlling an engine, comprising:
- setting a target torque of the engine;
controlling an engine torque based on the target torque;
setting an allowable torque that is greater than the target torque;
detecting a plurality of differing operating state parameters as indicators indicating an actual operating state of the engine;
individually calculating actual torques that are actual engine torques based on the plurality of detected operating state parameters;
selecting a largest value among the calculated actual torques as a final actual torque;
comparing the selected final actual torque to the allowable torque; and
generating a control signal according to a result of comparison between the selected final actual torque and the allowable torque.

8. An engine control device comprising:
-
a first operating state sensor that detects a first operating state parameter as an indicator indicating an actual operating state of an engine; a second operating state sensor that detects a second operating state parameter different from the first operating state parameter as an indicator indicating the actual operating state of the engine; and an engine control unit (ECU) that receives detection signals of the first and second operating state sensors and controls an operation of the engine, wherein the ECU is configured to set a target torque of the engine, wherein the ECU is configured to control engine torque based on the set target torque; wherein the ECU is an allowable torque setting unit configured to set an allowable torque greater than the target torque; wherein the ECU is configured to individually calculate actual torques that are actual engine torques based on the detected first and second operating state parameters; wherein the ECU is configured to select a largest value among the calculated actual torques as a final actual torque; wherein the ECU is configured to perform a comparison between the selected final actual torque and the allowable torque; and wherein the ECU is configured to output a control signal according to a result of the comparison.
