发明名称 ENGINE CONTROL APPARATUS
摘要 An engine control apparatus is used with a system equipped with an engine and an engine starter. The engine starter includes an electrical motor, a pinion gear driven by the electrical motor, and a pinion shifter which thrusts the pinion to a location where the pinion is engageable with a ring gear coupled to the engine. The engine control apparatus determines a pulsation parameter which represents a pulsating component of speed of the engine or a value correlating with the pulsating component. The engine control apparatus works to thrust the pinion through the pinion shifter to establish engagement with the ring gear and then rotate the electrical motor to crank the engine. The engine control apparatus alters a cranking terminating time as a function of the pulsation parameter. This minimizes mechanical noise occurring between the pinion gear and the ring gear at the start of the engine.

主权项 1. An engine control apparatus for use with a system equipped with an engine and an engine starter, the engine starter including an electrical motor which is electrically energized to produce torque, a pinion gear to which the torque, as produced by the motor, is transmitted, and a pinion shifter which thrusts the pinion to a location where the pinion is engageable with a ring gear coupled with a crankshaft of the engine, comprising: a pulsation determiner which works to determine a pulsation parameter which represents one of a pulsating component contained in a rotational speed of the engine and a value correlating with the pulsating component; and a cranking controller which works to thrust the pinion using the pinion shifter to establish engagement with the ring gear and then rotate the electrical motor to crank the engine, said cranking controller altering a cranking terminating time, the craning terminating time being when a cranking operation of the engine starter to crank the engine is terminated as a function of the pulsation parameter.
