Title:
自動車の制御装置
Document Type and Number:
Japanese Patent JP5564476
Kind Code:
B2
Abstract:
An automobile control device includes a function that can control drive torque of a starting device to an arbitrary value, and a positive rotation detecting unit having at least one of a function to detect whether an engine rotates positively and a function to detect whether the engine does not rotate reversely. The control device also has an idle stop function to increase the drive torque of the starting device when the positive rotation detecting unit detects that the engine rotates positively or does not rotate reversely. Accordingly, problems of malfunctions such as a reduction in a system voltage, abnormal wear of a brush in a starter motor, and breakage of a semiconductor switch are solved that are found in a conventional automobile control device having the idle stop function and that are caused by flowing of overcurrent when a starter is driven during swing-over that occurs immediately before engine stop.
