Title:
燃料噴射制御装置
Document Type and Number:
Japanese Patent JP6953862
Kind Code:
B2
Abstract:
To provide a fuel injection control device for properly correcting a detection error of a current value.SOLUTION: A fuel injection system includes a fuel injection valve (30) having a coil (31) to be energized on the basis of voltage application from a low pressure power supply part (45) or a high pressure power supply part (46) and a needle (33) to be opened/closed depending on the energization of the coil, current detection circuits (44a, 44b) for detecting a current value for the fuel injection valve, and a micro computer (41), the micro computer including an energization control part for controlling the start/stop the energization of the coil, a voltage acquisition part for acquiring a voltage value for the fuel injection valve at its terminal after the stop of the energization, and a correction part for performing correction processing to correct a detection error of a current value detected by the current detection circuits on the basis of the voltage value acquired by the voltage acquisition part.SELECTED DRAWING: Figure 2
