Title:
電子制御装置
Document Type and Number:
Japanese Patent JP7120029
Kind Code:
B2
Abstract:
A fuel injection device includes a first driver for driving a first valve and a second driver for driving a second valve. A control device performs an open control of the first valve multiple times by using the first driver, for enabling multistage fuel injection from an injection hole in one fuel cycle of an internal combustion engine via a high pressure fuel passage. The control device performs an open-close control of the second valve by using the second driver during an open control of the first valve by using the first driver, for controlling an inclination of injection rate of the fuel injection. The control device stops an output of a drive signal to the second driver when detecting an overheat of a drive circuit based on a temperature detection result of a temperature sensor.
