| 发明名称 | Idle stop condition determination method of engine | ||
| 摘要 | An idle stop condition determination method of an engine includes: calculating and storing a fuel saving estimation amount in idle stop of an engine on the basis of traveling information; calculating the amount of fuel consumption in restarting for restarting, when an idle stop condition of the engine is satisfied; comparing the magnitudes of the fuel saving estimation amount with the amount of fuel consumption in restarting, and stopping the engine in accordance with the result of the comparing; and restarting the engine, when a restarting condition of the engine is satisfied. | ||

| 主权项 | 1. An idle stop condition determination method of an engine performed with a control unit having a calculator and a memory, comprising; calculating a fuel saving estimation amount, with the calculator, in idle stop of an engine on the basis of traveling information, and storing the fuel saving estimation in the memory; calculating an amount of fuel consumption required for restarting the engine, when an idle stop condition of the engine is satisfied; comparing magnitudes of the fuel saving estimation amount with the amount of fuel consumption required for the restarting, and stopping the engine in accordance with a result of the comparing; and restarting the engine, when a restarting condition of the engine is satisfied, wherein the fuel saving estimation amount is calculated by multiplying an idle stop estimation time, which is calculated by dividing the total time of idle stop of the engine by the total number of times of idle stop of the engine, by the amount of fuel consumption in idling. | ||
